On-Grid Solar Could Change The Face Of The Energy Industry In India

by vemcoblogs -

Solar power is one of the most sustainable forms of energy. When you install a solar system, you choose from 3 types of solar power systems – On-Grid, Off-Grid and Hybrid. However, most consumers prefer on-grid solar systems to enjoy the benefits of net metering policies and avail credit on their electricity bills.

What is an on-grid solar system? 

An on-grid solar system or a grid-tied system is a solar power generation system that is connected to the local utility grid. This is the popular choice for corporates and commercial consumption as individual fluctuations – lesser or more – in energy production, get covered by the utility grid. Excess energy is sent to the grid’s power company in exchange for credit which can be cashed out at the end of a year. This is called net metering. As per the feed-in-tariff rates in your vicinity, you’ll be compensated for the extra power fed back to the grid. On the other hand, if your solar electric system is producing less power than you need, you can draw additional power from the grid. On-grid system also does away with the need to install battery back-ups. 

How much does an on-grid solar system cost?

An on-grid solar system costs around INR 45,000 to INR 65,000 per Kilowatt in India but the price varies according to the brand you chose. On an average, the on-grid rooftop solar system will cost you about Rs. 75 per watt.

Benefits of on-grid solar system

The various benefits include:

  • Significant reduction in electricity bills
  • Hassle-free installation
  • Easy maintenance as the system does not require batteries 
  • Longer life than an off-grid system
  • Government subsidies on installation of grid-tied rooftop solar systems
  • Advantage of net metering

How to get a subsidy?

Do you own an electricity meter? Do you have a valid identity proof and property papers to go through the installation of a grid-connected and battery-less solar system? 

If your answer to both the questions is yes, then you are entitled to claim for subsidies and other incentives from the government. 

However, the only thing to keep in mind is that an on-grid solar system won’t perform or generate electricity during a power outage. If the on-grid system continues to supply energy to the grid, the lives of the people working on the damaged grid will be at great risk.

There are several advantages of installing an on-grid solar system, which is why, many business owners, organisations and corporate customers are shifting to this eco-friendly lifestyle. By installing a grid-connected solar system, you are not only choosing an eco-friendly life, but also availing of credits on your electricity bills, courtesy net meters. Currently, this program is a huge success in Spain, Australia, Canada, Denmark, Italy and The United States. In India, it is still in the process but it is expected that very soon, on-grid solar power systems will change the face of the energy industry in the country.If you need a trusted partner who can help you switch to solar in a hassle-free way, VEMCO Solar is there for you.

6 Things to Ask Solar Consultant

by vemcoblogs -

It is really important to let your guards down and learn everything about solar panels before you plan to get one for your residential or commercial space. Well, having a direct chat with solar consultants might be your guide over here. As they are associated with this field for a pretty long time, you can expect to get quality responses to all your queries. So, let’s learn about the 6 things that you should primarily ask your consultant, especially from Vijay Engineering and Machinery Company (VEMC).

1.Don’t forget to ask about the Financial Options:

Can you benefit from that tax credit? Does the solar energy consultant have any lease option or competitive loan by his side for the clients? Most companies will push for the Power Purchase Agreement. It will make your solar contractor the electric company. It means you are not going to own the system and just need to pay for the power it produces for your place. But, the solar contractor has every right to raise the rates. That’s why another loan or leasing program with a 0 down and 0 increase guarantee is always important for most customers.

2. Ask to check their design centre:

If you want, the consultant can sees the company’s design centre or operation office. Avoid letting them meet you at your place. You need to know more about the company and its precise workflow because you proceed further and get panels from their sides. When you have experienced groups like Vijay Engineering and Machinery Company (VEMC), you don’t have to worry much. With 72 years of experience, you can expect only the best from this source!

3. Ask for expansion of solar energy system in future:

This is another interesting point for you to jot down whenever you are dealing with the solar panel consultant for your queries. Ask them if they can expand the current solar system later if the need arises. With some countries becoming less dependent on fossil fuel, the consumers need to know if they can create a larger system in the near future for accommodating the power needed for their devices.

4. Ask more about the panels:

You should ask the consultant about the solar panels they are planning to install at your place. Always remember that not all panels are the same. Some are more durable and efficient than others. Experienced companies like Vijay Engineering and Machinery Company (VEMC) are able to produce around 75% more energy over the course of their working period. So, always research the panels through one third-party source to ensure that the products will last long.

5. Ask about the benefits of working with them:

There must be some benefits involved while working with a local solar contractor over a national brand. So, do ask about those benefits before you get yourself involved with their solar panels. Vijay Engineering and Machinery Company (VEMC) is one ISO 9001:2015 certified firm and a pioneer in the field of electromechanical engineering items, allied equipment, and all the necessary services. This company is CRISIL MSE-1 rated. They are known to present strategic expansion and consistency throughout for providing excellence in service, quality of product, and leadership. So, working with this team will save you a lot of money and time!

6. Ask if moving towards solar panel is a good call for you:

Well, the answer to such a question can be a complex one. It depends on multiple physical factors. How much are you currently paying on your electric bill? How much shade does your roof actually get? Why are you looking for solar panels? Is it because of the financial benefits or anything else? Make sure to get these questions answered first before you can opt for the solar panels.

Get help from Vijay Engineering and Machinery Company (VEMC):

If you are currently eyeing the most affordable solar panel system cost and panels that are designed to last long, then Vijay Engineering and Machinery Company (VEMC) is your name. VEMC Solar presents end-to-end solutions, starting from selecting the right set-up kin to the final selection of best Opex or Capex models.

How To Reduce Unexpected Long-Term O&M Costs With A Smart Solar Solution

by vemcoblogs -

Once a solar power plant is installed, the next aspect to be considered is operations and maintenance (O&M) management. It is a crucial aspect of any solar project since it mitigates the risks of unexpected costs and must never be overlooked. Efficient O&M ensures the generation of maximum power, while also providing a sizeable return on investment. No matter the scale of your photovoltaic (PV) module usage, you will always need an effective and efficient O&M solution. And you can do this by taking the SMART goals approach.

What is a SMART solar solution?

In management practices, SMART is an oft-used acronym for better guidance towards your set goals. SMART stands for:

  • Specific: Making sure that your objectives are well-defined and clear.
  • Measurable: Chosen criteria must be measurable to ensure the tracking of progress. 
  • Achievable: Keep your goals attainable. Impossible goals can lead to demoralization.
  • Realistic: Keep your objectives realistic, relevant, and within reach.
  • Timely: A clearly defined timeline is necessary along with target dates.

The SMART systematic approach towards making your goals clear and reachable will help reduce long-term O&M costs.

What are the steps to reduce unexpected costs?

  1. Preventative focus: In order to keep the equipment used in solar panels in top condition, it is necessary to conduct advanced analytics and condition monitoring testing. This reduces the possibility of any problems arising in the future, thus saving the time and money spent on remedial measures.
  2. Timely maintenance: Just as we abide by the user manual for maintaining other pieces of equipment, doing the same for solar solutions is always a good idea. Timely maintenance greatly reduces the possibility of errors and production loss. O&M providers like VEMC can offer planned maintenance schedules to maximise equipment performance and minimise downtimes.
  3. Spare management: Creating a detailed breakdown impact analysis of solar plant sites is necessary to prepare a priority matrix for spare management and better maintenance.
  4. Remedial maintenance: One of the main aspects of O&M is, of course, remedial maintenance. Any solar plant must have proper planning in place for repairs or replacement. This not only ensures immediate solutions but also helps avoid costly system failures.
  5. Safety: With the handling of large equipment comes the problem of ensuring the safety of everyone working around it. An experienced O&M provider will be equipped with skilled employees who perform their jobs with utmost care. They will also provide their maintenance personnel with the safety equipment needed to perform their jobs in a secure manner.

That said, it’s absolutely necessary to have an O&M plan in place for your solar plant to alleviate long-term costs. At VEMCO Solar, our valued clients are provided with customized plans to fit all their needs.

Industrial Process Pumps – An Overall Detail

by vemcoblogs -

In layman’s terms, a process or industrial process pump is a centrifugal pump, widely used in chemical processes, mostly in petrochemical industries and oil refineries. The design is mainly that of the back pull-out. Like most of the chemical pumps, these process ones are used for handling some of the aggressive chemical fluids.

These options are also highly suitable for higher system pressures and temperatures. So, if the process pump is used in any oil-based industry, it will generally comply with the requirements or API standards.

An Overview of the Industrial Pumps:

These industrial pumps are the most common and popularly used pump types for transferring fluids. It uses an impeller for displacing the water or any type of fluid by using its centrifugal force. This undisputed pump choice is perfect for delivering liquid from one location to another.  The industrial pumps are used in multiple sectors including municipal, agriculture, power generation plants, industrial, mining, petroleum, pharmaceutical, chemical, and all the other options. 

  • Reputed Industrial pumps distributors like Vijay Engineering & Machinery Company  in Mumbai work hard to deliver top-notch quality centrifugal pumps. These pumps are of high utility and can handle large volumes of liquids having high or low PH and fluids with flammable properties.
  • These pumps are mainly designed and suitable for liquids with low viscosity that pours much like oil or water. The more viscous ones, like 10 or 20 wt. oils at around 68 to 70 degrees F will need added horsepower for these pumps to work.
  • Due to the current design of centrifugal pumps they work out to be the effective solution for various applications. Moreover, because of few parts installation, maintenance remains easier and cheaper, when compared to positive displacement pumps.

The above information proves to be a great resource to gather insights about industrial pumps. It will further enable you to select the best industrial pump based upon your requirements.

Major factors affecting the selection of industrial pumps:

To get a better understanding of industrial water pumps in Mumbai, it is important to learn more about the factors, which actually affect their performance level. The major points are listed below for your reference:

  • MOC (MATERIAL OF CONSTRUCTION):  

The materials used for manufacturing the industrial pumps will definitely put a hold on the performance level. The performance level of the water pumps varies based on the material of construction.  Some of the materials used in pump construction are bronze, cast iron, manganese bronze, multiple grades of stainless steel, duplex steel, haster alloy metallurgy, and nickel-aluminium bronze

  • TEMPERATURE:

Another interesting factor affecting the performance rate of industrial pumps is the heat or temperature. The pumps are highly effective on their own within temperatures around 300 to 500 degrees F. It is important the temperature of any process liquid as some of the liquids when in contact with the atmosphere may solidify and hamper the complete process.

  • VISCOSITY:

A higher level of viscosity is difficult to pump up liquids. Higher viscosity liquids will act more like solid and will make pumping a difficult process. But, a smooth-flowing liquid can enhance the working mechanism of industrial pumps well.

  • SPECIFIC GRAVITY:

Generally speaking, specific gravity is the weight of the presented volume of liquid as expressed in relation to the weight of an equal volume of clear water as around 62 degrees F. It is mostly expressed as 1.0.

  • NPSH REQUIRED:

For better functions, it is important to learn about NPSH-A and NPSH-R as two major values.  NPSH-R is the suction pressure at which the cavitation has reduced pump performance by around 3%. NPSH-A is calculated from the suction portion system configuration. Note that NPSH available should always be greater than NPSH required. The concept of NPsh is extremely important while evaluating the selection of any chemical process pump.

  • MECHANICAL SEAL SELECTION:

Selecting the right mechanical seal can enhance the performance level of industrial pumps. The right mechanical seal needs to be wear and corrosion resistant with good thermal properties.

The leading experts:

If you are looking out for industrial pumps, then get in touch with Vijay Engineering and Machinery Company. Our evolution can be traced back to the year 1948.

Is Solar Energy Still A Good Investment Under New MERC Norms?

by vemcoblogs -

Even though the recent revision of the Maharashtra Electricity Regulatory Commission (MERC) tariff has slashed the price for power distribution companies, what does it mean for the solar energy sector? Is it still a good investment?

Earlier, the Maharashtra State Electricity Distribution Company Limited (MSEDCL) had proposed that a considerable grid support charge should be added to net metering rooftop solar systems which have a capacity of over 10 kW.

Well, the good thing is that despite the looming possibility of solar power prices to rise amidst the coronavirus pandemic, the Commission decided to NOT levy any support charges to on-grid solar system installation on rooftops. This will hold until the total rooftop solar photovoltaic module capacity of the state reaches 2 GW. 

The fact is that the decision was taken against the regulatory mandate to impose grid support charges in an attempt to reduce additional tariff burden on non-solar consumers. An additional banking charge has also been approved that includes an energy adjustment of 7.5% for HT and 12% for LT of the excess generated energy which will be fed back into the grid.

Also, the commission has exempted additional fixed charges behind the meter rooftop solar to ensure that such installations are registered primarily for grid security.

These latest changes, indeed make both off-grid solar system and on-grid solar system a good investment option. Plus, you have Vijay Engineering and Machinery Company to provide you with the best solar solutions and maximise your savings.

How Revised MERC Tariff Is Going To Affect The Consumers

by vemcoblogs -

The coronavirus pandemic has not only slowed down everyday life but has also wreaked havoc on India’s economy as businesses and trades all across the nation are floundering to stay afloat, and the average middle-class individuals are struggling to make ends meet in the absence of functioning work sources. In this bleak scenario, the recent revision of the Maharashtra Electricity Regulatory Commission (MERC) tariff has slashed the price for power distribution companies in an attempt to boost the state’s economy but is it enough? Or is it time to switch to more renewable sources of energy like solar street lights, solar inverters, etc.

Having been applied since April 1, the MERC rates have been reduced for the first time in 10-15 years. 

The Impact of the Revision on Consumers

The tariff has been reduced by 5-7% for domestic consumers, while industrial and commercial consumers now avail the benefit of the prices being reduced by 10-12%. But compared to these high benefits, the tariff has been barely reduced for agriculture consumers – farmers received only a 1% reduction in electricity costs.

These revisions are for a period of five years and will allow power distribution companies to supply to consumers at a much lower rate. 

Still find it costly? Well, all you have to do is switch to a “solar” lifestyle with VEMCL’s aid! From solar rooftop to ground mount solutions and off-grid to on-grid solutions, we are here to make your smart transition easier with your particular need specific customised solutions.

Impact Of Pandemic COVID – 19 On Solar Business

by vemcoblogs -

There is no section of human life that hasn’t been affected by the novel coronavirus pandemic. This includes the solar energy business too, which has taken a hit as well, but unlike other sectors, not only has it not been too severely affected but is also expected to recover a lot quicker!

Many global industry analysts had predicted that there would be a shortage of solar wafers, module glass, and other components in China, which would, in turn, lead to a rise in solar component prices, but thankfully, no such escalation has been observed, though there have been disruptions in the supply chain. 

When it comes to the solar energy business, China dominates the PV modules market with India as one of its biggest buyers. In fact, Chinese firms provide 80% of the solar cells and modules used in India as they make up for 40-60% of the total cost of a solar energy project. Luckily, nearly 80% of the solar industry in China has already recovered and whatever supply chain disruptions have taken place are expected to be fully restored in some time.

As the curve of the pandemic has almost flattened in China, employees are gradually resuming work as restrictions are being eased, which means that export of many solar energy-related materials like PV panels, aluminium frames, used in the creation of solar grid system, and other key components like solar inverters, module mounts, etc. has now become possible. 

Industrial Air Compressor: Application, Uses & Working

by vemcoblogs -

Industry-used air compressors are very different from your regular home-used air compressor. If you are unaware of industrial air compressors’ features and capabilities, it would be tough to use them in the industry.

How does compressed air work? 

The compressed air basics are apparent. Compressed air is only air that is held under pressure more significant than the atmosphere. Compressed air technology has been around for decades, but it has progressed like any other technology. It is commonly used commercially and residentially, but compressed air technology’s industrial applications are enormous.

 An air compressor functions similarly to that of your car engine. Pistons press down on a combination of air and gasoline in your car engine. The mixture compresses and then ignites, which generates energy. An air compressor does the same thing, in the simplest form. A piston forces air down in the compressor, pressurizes it, and stores it in the underlying tank. The air compressor used today can hold vast quantities of pressurized air in its tanks because of technology.

Most Common Industry Applications

Air compressors are used in various industrial applications, from the production of pharmaceuticals and food and beverages to nuclear power and the production of chemicals and petrochemicals. The design, engineering, and service capabilities provide a broad cross-section of industries with efficient operations and cost savings. Industries that routinely use highly compressed air volumes include the following:

Petrochemical / Chemical

Chemical & petrochemical plants require compressed air of very high quality. Additionally, these plants also choose inherently safe systems regardless of the unsafe environments that might occur.

Pharmaceutical

As with the chemical and petrochemical industries, there are stringent criteria for compressed air for pharmaceutical applications. It is essential to provide compressed air of the highest quality, especially when the air contacts raw materials or finished products.

Food and Beverage

Again, the Food and Beverage Industries demand high-purity air supplied consistently as with pharmaceuticals. The atmosphere that could come into contact with the substance of food or drink must be safe.

Manufacturing

In general, compressed air quality may vary widely in manufacturing applications, depending on the use. Some applications need an air of general-purpose, while others require a mixture of general-purpose and instrument grades of higher quality.

Metal Manufacturing

Air compressors are used for several processes at the finishing end at metal production plants. Pressurized air is used as newly shaped metals take shape to power the pneumatic tools that cut raw metal supplies into measured lengths and specified conditions. The grinding tools that smooth out and clean the surfaces of metal items are often used by air compressors to power them.

 Ships Building

The shipbuilding processes involve a complex arsenal of instruments and machinery, many of which depend on air compressors. Air-powered tools are used to cut the pieces, smooth the surfaces, refine the edges, and attach separate components into one during shipbuilding phases where the parts are made. Further rounds of pneumatic tools are used after the assembly stages to paint and apply finishes to different naval vessel details.

Uses

Energy Air is, first of all, used to store and transfer energy for mechanical work. It is used to power pneumatic manufacturing machinery, air-operated lathe chucks, pressure clean parts, and manufacturing to convey or cool components.

On the other hand, active air is needed as a dynamic and integral part of a specific method. In this situation, the air comes into contact with the product; the air quality is, therefore, essential.  The air compressor dealers in Navi Mumbai ensure clean, dry air quality, or CDA quality for short, is improved using oil-free compressors and treating the air using one of the many quality air tools available. 

5 Basic Questions Need to Ask Before Purchasing the Air Compressor

by vemcoblogs -

A compressor has a wide variety of applications in various businesses and manufacturing industries. When you think about an air compressor, the one thing that pops in mind is that it is present at almost every shop from the garage to the dentist’s office. The popularity of the compressor is because it is reliable and can work in virtually any setup and keep well to the pace. But many a time people are made fools just because they don’t know anything about compressors while buying one. Here is a checklist of questions that will help buy a new compressor. Answering these questions will help in finalizing the right air compressor based on your needs.

What is the application for which the compressor is required?

The answer to this question decides the type of compressor that you are going to buy. The size of the compressor is determined by the most crucial factor that is the type of application you are using it. Also decide how long you intend to use the compressor whether it is 10 or 20 hours a day, five days a week, or only occasionally. Buy a perfect compressor like a screw compressor if your demands are consistent. If the needs are constant, get a compressor that is designed for a duty-cycle which equals or exceeds specified requirements.

Where will the compressor be placed?

The second main question that you have to answer before buying a compressor.

For example, if it is to be installed outdoors, the compressor would require superior protection against rain and heat. The compressor must have adequate ventilation for proper functioning since most reciprocating compressors are air-cooled. The compressor should not be placed inside of a closet. The closet, in most cases, won’t have enough ventilation to handle the heat produced by the compressor. Also, be mindful that sunlight doesn’t fall on the equipment and the noise generated it.

How much PSI do you require?

The PSI of the compressor will differ based on the type of work that you perform. The demand for compressor pressure depends on the needs of the tools that you are using. Check the system that requires the highest volume of air and use that as a reference to select the compressor. Also, be careful that you do not overpressure the system. Go according to the specification of the manufacturer. The pressure also determines whether the unit should be a single-stage or two-stage compressor.

How much airflow (CFM) does your operation require?

Cubic feet per minute or CFM is the measure of airflow created by the compressor. Sometimes the ideal volume of air is not exactly the ideal CFM ratings. In that case, take a load cycle on the existing compressor for all shifts if possible. Installing a flow meter on the new compressor for a nominal cost can save you thousands in the long run. Once you have determined your flow requirements, you can match that to consider the needs for future growth. Oversized compressors will use more power and increase the cost of power in the long run.

What is the type of control system that you need?

There are three variants of a control system that can be employed in a shop. The first is the start/stop system, the second is the constant speed control, and the last one is the dual control system. The Elgi air compressor has various types and will suit perfectly for your specifications.

Bottom line

Compressors help in maintaining the quality of the shop and efficiency. You can go for a screw air compressor that would be the best choice due to capabilities and functionality.

Does The Current Pandemic Situation Will Impact the Renewable Energy Sector?

by vemcoblogs -

The novel coronavirus 2019 has reset the global economy while the impact of the virus on the energy sector is no different. The slowdown and the lockdown have led to a remarkable decline in the demand for energy globally. While the after-effects of the pandemic are still being played out; there will be some impact on the renewable energy sector. 

The recent situation presents both opportunities and threats to the renewable energy sector. However, since the total energy generated using renewable sources is via an off-grid solar system or wind energy, the impact on this sector shall be rather low. Due to the slowdown in demand of renewable resources during this short-term, the number of new renewable energy projects may experience a slight downfall. In addition, the ongoing projects that have already been announced shall experience some delay altogether that will turn the demand of renewable energy at a low rate. 

-In the medium term, however, the demand for renewable energy is again expected to again reach the pre-pandemic situation and that shall lead to opportunities. The disruption of the supply chain has created a shortage of equipment like an on-grid solar system, panels for renewable energy providers in India. While this is negative for the short term, over the medium term, it has led to an excellent opportunity for the local manufacturers of equipment for renewable energy. Indigenous companies manufacturing equipment for renewable energy shall now be able to gain a foothold in this market.  An increase in the local supply of equipment shall give a boost to renewable energy production in India and other emerging economies.

The reset of the energy demand caused by a pandemic is a once in a lifetime opportunity for countries like India to pursue clean-energy more aggressively. The pandemic has made governments globally realize the importance of public health on the accelerating switch from the polluting fossil fuel economy to the renewable energy economy. The governments shall focus on providing incentives, subsidies and stimulus packages on the renewable sector to move away from the adverse effects of fossil fuels. 

For India, specifically, over the medium term, this pandemic offers tremendous opportunities. Since the oil prices shall be much lower, it will free-up the government’s resources w.r.t foreign reserves. The government may use these resources to give a boost to renewable energy, as a means to focus on long-term public health. These incentives and subsidies would help develop a complete ecosystem of renewable energy right from equipment manufacturers to service providers. Globally, the pandemic has made people realize to de-risk their entire supply chain from a single country. This shall provide new opportunities for the renewable energy sector in India to export their products and service globally in the post-pandemic world. 

All the after-effects of the pandemic would be realized once the situation is restored to normal post the pandemic. However, the short-term is going to be extremely difficult for the renewable energy sector globally. Reduction in overall energy demand, supply chain disruptions, unavailability of inspectors, servicemen and installers shall lead to short term adversity for the entire sector. However, the pandemic has created a tremendous opportunity for the governments over the globe to come together and focus on public health by giving a boost to global renewable energy demand through incentives and subsidies. For India, over the medium term, as a means to de-risk the supply chain, the pandemic shall open opportunities for renewable energy equipment manufacturers. 

How Does Water Pump Contribute As A Back-Bone For Industrial Sectors

by vemcoblogs -

All pumping equipment is intended for one purpose, and specifically, for pumping water. They can be used in communal systems, in industry, and even in everyday life. For example, you can bring the installation of a mechanism for pumping wastewater in private sewer systems. Industrial water pumps are more complex. It’s hard to imagine how, presently, the supply and pumping of water can be done without a centrifugal pump. After all, pumps play a crucial role in this process.

In the world pumps, there are various types like Vertical Inline Pumps, Multi Outlet Pumps, and Vertical Split Casing Pumps. This is since it is possible to supply water in different ways, and not only water can be supplied and pumped out, but also other liquids.

It is essential to choose the right pump, in particular when selecting water pumps. For example, centrifugal water pumps or external circulation pumps. The only question is which pump and why.

When choosing a water pump, you can be guided by many criteria, since the choice of products is large, but more important criteria that will prompt the right choice of pump can be:

– Scope

– Tasks that the pump must fulfil

The scope of pumps for water can be domestic and industrial. If water pumps are needed for an enterprise (production, non-production), institutions, or other similar fields, it is necessary to choose water pumps in the industrial category.

Centrifugal pumps are dynamic hydraulic machines and are characterized by low cost in contrast to other devices. The simplicity of design, reliability in operation have led to their wide distribution in various industries. The advantages include continuity of fluid supply, high efficiency and reliability, and ease of automation control. Industrial centrifugal pumps available in India are used in water supply, heat power engineering, chemical, and nuclear industry.

The necessary pressure is created in the pump due to the centrifugal force when the impeller rotates. Inside the housing, the impeller is rigidly mounted on the shaft. When the impeller rotates, a centrifugal force appears, and a vacuum appears in the central part, and pressure increases on the periphery. Therefore, the liquid is pushed into the pressure pipe. Most pumps are driven by an electric motor, which can be located in one housing with the pump unit. Such an electric centrifugal pump has compactness and high efficiency.

Centrifugal pump is divided into several types, depending on the number of stages, the flows flowing along with them, as well as the conditions for liquid drainage, drive method, shaft location, and purpose. For example, a surface centrifugal pump is used to organize water supply from open sources and is installed above the surface of the pumped liquid. The working chamber must be filled with liquid before starting.

To date, the market is simply clogged with pumping equipment. This gives a certain advantage for buyers who can choose for themselves. But you must have knowledge of how the pump is used and its maintenance. Furthermore, getting the ideal type of pump is essential.

Working of ELGI Air Compressor

by vemcoblogs -

How ELGI air compressor works?

An air compressor is a device designed to pump compressed air. It is used to ensure the circulation of cooling refrigerant in a closed circuit, and the pumping of pressure into various containers. This equipment is widely used in medicine, industry, and household. Its presence allows you to perform a wide range of actions.

The principle of operation of the ELGI air compressor can be described as follows.

  • When the engine starts, the crankshaft begins to rotate, transmitting reciprocating movements through the connecting rod to the piston.
  • The piston, moving downward, creates a vacuum in the cylinder under the influence of which the inlet valve opens. Due to the difference in air pressure, it begins to be sucked into the cylinder. But before it enters the compression chamber, air passes through the filter.
  • Further, the piston starts to move up. In this case, both valves are in a closed state. At the time of compression, pressure begins to increase in the cylinder, and when it reaches a certain level, the exhaust valve opens.
  • After opening the exhaust valve, compressed air is directed to the receiver.
  • When a certain pressure has entered in the receiver, a pressure switch is activated, and air compression is suspended.
  • When the pressure in the receiver decreases to the set values, the pressure switch starts the engine again.

How to choose an industrial air compressor?

To select the right compressor, first of all, you need to determine how often it will be used, depending on your needs for compressed air.

You are also required to determine if you need a portable compressor or whether it will be used indoors. In this case, it is necessary to ensure good ventilation of the compressor to make sure that it has optimal cooling.

Also, consider the continuous running time of the compressor. Manufacturers usually indicate the duty cycle on these elements. This duty cycle allows you to determine the duration of the compressor for one hour. 

Purpose and principle of operation

What is an air compressor? This is a device designed to compress air and pump them to the required place. How does it work? The principle of operation of the ELGI compressor is quite simple; atmospheric air enters the mechanism that performs its compression. For this, different methods can be used. The mechanism that compresses the air determines the device and the principles of operation of the compressor. For the effective operation of the equipment, it must be connected to the electric network and the air network, through which compressed air will be transmitted. 

Common problems of air compressor

Unit overheating

Usually, the unit may overheat when operating in intensive mode or at an increased ambient temperature in the room. If the unit still overheats under standard operating conditions and normal room temperatures, then a clogged air filter may be the reason behind the malfunction. It should be removed and washed, then dry it properly.

Knock on the cylinder

It is caused by a breakdown or wear of the piston rings due to carbon deposits. Usually, it appears if you use low-quality oil. Knocking-in the cylinder can also be caused by wear on the connecting rod. These parts should be replaced with new ones. When the cylinder and piston are worn, repair of the air compressor consists of boring the cylinder and replacing the piston.

ELGI air compressors are very essential since they require small maintenance. Apart from that, they are highly reliable and huge. This is the reason why they are good for industrial applications. Ensure that you look for reputable dealers in the same product. You may opt for the ELGI air compressor dealers in Mumbai, who are reliable and have the best products.

Difference between Magnetic Driven Centrifugal Pump & Mechanical Seal Centrifugal Pump

by vemcoblogs -

It’s undoubtedly a difficult choice to make between a magnetically driven centrifugal pump and a mechanical seal centrifugal pump! To save you some time and constant Google searches, let’s give you a gist about the main comparison between the two: 

  • Sealing the fluid

In the sealed centrifugal pumps, the presence of a mechanical seal prevents fluid leakage even while the water pump is in operation. On the other hand, magnetic water pumps do not require a seal since it has a containment shell at the end that ensures a safe enclosure for any leakage to happen. 

  • Maintenance cost and life

In sealed centrifugal pumps, there is a continuous movement between the parts which are in close contact with each other. This arrangement results in easy wear down of the elements and hence, constant maintenance costs. But, because the magnetic submersible motors do not contain any seal, there’s no need for replacements, which costs less. 

  • Application of fluid types 

The mechanical centrifugal motor is capable of pumping out some hazardous fluid, but there’s always a scope for leakage there. Whereas, magnetic pumps due to their inherent design are comparatively safer for hazardous liquids as there is zero scope of leakage. Also, hazardous liquids are generally more expensive and require safe use, which proves magnetic pumps to be more effective for the purpose.

Difference Between A Centrifugal Pump And A Vacuum Pump

by vemcoblogs -


Centrifugal pumps and vacuum pumps differ from each other for multiple reasons, and here is the detailed explanation for both that reflects those reasons: 

Centrifugal Pumps 

Popularly known as hydrodynamic pumps and dynamic pressure pumps as well, centrifugal pumps are manufactured by making use of the primary centrifugal forces. The flow happens when the kinetic energy produced with the help of a rotating turbine or electric motor is turned to pressure in the liquid. 

If kept in comparison with a vacuum or any other pump for a fact, these water pumps are easier to install. Unlike others, they are manufactured with the help of the back pullout-design process. When a repair is required, the parts can be taken apart and restarted within a short period.

Vacuum Pumps 

Vacuum pumps are those types of submersible pumps that are used to pump out the gases, leaving a partial vacuum aside. While choosing the best vacuum pump among many, the flow of air removal in the pump, the amount of vacuum that is produced, and the power required to create the vacuum are some of the factors that need to be considered. Keeping this in mind, it’s mandatory that the manufacturers should provide information on flow-rating availability. 

When put in comparison with other pumps used in submersible motors, vacuum pumps have comparatively lower power requirements. For continuous pumping, large-sized vacuum pumps are put to use. The only drawback that vacuum pumps have that centrifugal motor doesn’t is that they get overheated if put in continuous use.

On-Grid or Off-Grid

by vemcoblogs -

Many people think that whenever one switches to solar energy, the only option they have is to install an off-grid system, especially in rural areas, where extending the power lines is difficult and expensive. But before you make a hasty decision, a better idea is to consider the two options in front of you- off-grid solar system and on-grid solar system. 

Here are a few differences between the two: 

  • On-grid basically means that your solar system is connected to the local company’s system eg. MSEDCL, Adani, BEST. Generally, residential homes opt for on-grid solar systems where there are good grid parity and lesser downtime. Whereas, the off-grid system means that you’re not connected to any utility company. 
  • Using the on-grid system, the extra energy produced that’s not used by you will be stored in the grid’s power company. This stored energy will act like a credit that can be cashed out at the end of the year as per the local distribution norm. Whereas, using an off-grid system, you’ll need to install a backup battery for storing energy this way. As there is no good parity and a higher electricity outage dependency on battery storage of electricity which makes more sense and has longterm financial viability. But the challenge is that this battery is rather expensive thus increasing the cost spent on installing the off-grid solar systems.
  • Though over the next 5 years the cost of battery storage shall be reduced due to the higher scale of economic order quantity. 

So stay calm! Leave the extra work to Vijay Engineering and Machinery Company, the best solar EPC consultants in Thane. We will ensure that you get the services that will benefit you the best- so whether it is choosing the right grid system or its proper installation; we are at your service!

What is an Isolation Valve, and in what conditions is it used?

by vemcoblogs -

An isolation valve is used to manage the flow of fluids in the plant process and prevent it from flowing to a specific location. The primary purpose is to prevent the flow of contaminated components such as blood, pharmaceuticals, or any medical devices.

Isolation valves come to use under multiple circumstances and for various technical equipment as stated below: 

  • Firewater control 

Firewater pumps are extremely risky and dangerous to handle, especially when they need to be removed. But, isolation valves ensure the safe removal of firewater control pumps and prevent any impact on the entire system of the centrifugal motor.

  • Pipeline safety

The blockage of drain lines or water pumps is quite a common issue due to ice or hydrate formation. The worst cases might even include an uncontrollable situation where the submersible pumps freeze open and are impossible to be shut back again. To avoid such mishappenings with the motor, isolation valves could be installed between the inventory and expected leakage area of the submersible motors, eliminating the scope of any leakage in the future. 

  • Oil and gas wells

Valves in the oil and gas industry ensure confidence and reduce any unforeseen risks. Every industry or plant must adhere to the safety and health guidelines provided as per the government, where oil and gas industries are quite prone to damage to the environment. Even a small gas leak in centrifugal pumps can lead to substantial environmental concerns in the future. The stem seal designs of isolation valves prevent any such leakage and ensure adherence to the social and environmental guidelines.
