Industrial Process Pumps – An Overall Detail

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 resistance with good thermal properties.

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

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

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

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

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

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?

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

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

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 Mumbaiwho are reliable and have the best products.
