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.

What is a water hammer? What are its ill effects?

by vemcoblogs -

A water hammering  effect happens when a sudden closure of the valve causes the back and forth movement of water at supersonic speeds. Water hammer is an understudied topic, and unaware of the fact that residentials have it in their submersible motors, nobody seems to care. In the light of water hammer- for residentials, it’s just that loud noise when the submersible pumps are shut. 

Having said that; a water hammer could have some adverse effects as stated below: 

  • When a centrifugal pumpset suddenly shuts at any given site, the mass of water before closure will still be moving, hence a high pressure shall be created, resulting in a shock wave. This process makes a similar hammering sound that one often hears after shutting their centrifugal pumps.
  • In the worst case, water hammers can even cause the pipelines to break if the pressure is too high. For safety purposes, air traps are often installed to absorb the damaging factors caused by high pressure.
  • The water hammer can also harm valves and pipes in case of any water, oil, or gas application. This happens in the same process of high pressure, as mentioned above, which causes a spike, thereby damaging gauges. This can occur even if the gauge has a correct pressure range for the flow application.

To avoid these adverse effects of a water hammer, air chambers prove to be quite useful because they soften the impact and hence prevent the hammer effect.

But you can swiftly avoid the chances of a malfunctioning water pump, by opting for the high-efficiency Kirloskar pumps that Vijay Engineering and Machinery Company, the best pump dealers in Mumbai, promise to provide to you. Counted amongst the reputed pump dealers in India, VEMC is the answer to your problems!

In which direction does water enter the centrifugal pump?

by vemcoblogs -

So, how does water enter the centrifugal pump? Well, there are different ways in which it makes it to the eye of the impeller in the pump:

  1. End suction and top discharge centrifugal pump:

 In this arrangement, the water enters the impeller horizontally and then proceeds to discharge vertically from the top of the pump, a good example of which is the single stage horizontal centrifugal pump popularly known as end suction back pull out pumps

  • Top suction and top discharge centrifugal pump:

The water both enters and discharges from the top of the pump,i.e. top half of the casing  something which happens in a boiler feedwater pump.popularly known as Multistage pump.

  • Side suction and side discharge centrifugal pump:

Here, the water both enters and exits from the same direction, but in this case, it is from the side.i.e. bottom half of the casing. A classic example of this type of arrangement is an axial split horizontal centrifugal pump. Popularly known as side suction side discharge pump

No matter which method is employed, they are available in a variety of options and are applicable in several applications.

What will happen if the speed of the centrifugal pump doubles, keeping other parameters the same?

by vemcoblogs -

What happens if we increase the speed or rather double it, keeping the other parameters constant? This is what will happen:

It is governed by the Affinity Laws (Laws of Similitude)

Flow ( Q ) is directly proportional to the ratio of the speed

Head ( m ) is directly proportional to the square of the ratio of the speed

Power required is directly  proportional to the cube of the ratio of the speed

Eg.  If flow and head is 10 m^3/hr and 10 m @ 1450 rpm respectively

        Then @ 2900 rpm the flow shall be 20 m^3/hr and head shall be 40 m.

Hence, increasing the speed of water pumps or doubling it without a proper understanding of the consequences that it will have on the pressure and flow of the pump can lead to the entire system to fail.

On the contrary, the fact remains this has been happening for the longest time possible. This means that the solar, panel still plays a significant role in increasing energy in the future and reducing the power consumption expenses.

The costs of remaining dependent fossil fuels instead of that of renewable had started to increase. However, sun and wind still can provide the ever-increasing portion of day to day energy for the consumers, especially those who are vulnerable to electricity.

Solar panel, regardless of one or dozens, they reduce the cost of electricity significantly. It, however, does not matter whether the solar panels are manufactured commercially or made for homeowner use.

Once your first panel starts working, you will start seeing the saving that it brings to you through reduced electricity bills

Finally, installing a solar panel at your home is the best way of reducing the monthly electricity bill expenses. Therefore it is worth your money. Although it may be hard to know which one is suitable for your home, you should consult experts to ensure you select the best solar panel since the set up will last for many years.

How To Decide – Reciprocating Compressor or Screw Air Compressor

by vemcoblogs -
Elgi Screw Compressor & Reciprocating Compressor

In recent times, more and more industries rely on compressed air and are, sometimes, called the 4th utility of any industry. When looking for an air compressor, there are different types of compressor like Reciprocating compressor, Vane Compressor, Screw Air Compressor, Diaphragm Compressor, Centrifugal Compressor, and so much more. We will talk about the 2 popular types of compressor, namely the reciprocating and screw air compressor (also known as the rotary compressor). Users often get confused between these 2 variants during purchase; however, in order to make the correct decision, you will need to understand how they operate.

Reciprocating Compressor

In a reciprocating compressor, air is taken into a cylinder and then compressed to a higher pressure with a piston using reciprocating motion (much like an engine). Piston compressors are the most common type of compressor used in most industries because of their lower capital investment. These compressors, however, make a lot of noise and vibration. As the compressor operates on reciprocating motion, there is pulsating air produced, which causes the inlet and outlet valve blades to open and close multiple times a second, making higher noise levels. Most air compressors manufacturers provide an allowable duty cycle of 60%-70%. That said, a general recommendation is that when your compressor is idle for more than 50% of the time, it is best to go for a reciprocating compressor. Piston compressors are usually oversized to allow some idle time as they operate at higher temperatures. BAC Reciprocating Compressor ranges from 0.5HP to 20HP and are manufactured to industry standards to withstand above 70% duty cycle.

Screw Air Compressor

Screw air compressor consists of 2 rotors, rotating in the opposite direction, compressing air between the lobes to a higher pressure. Since the rotors are rotating and not reciprocating, there is minimal vibration, wear, and downtime compared to a reciprocating compressor. In a reciprocating compressor, there is a high friction loss between the piston rings and cylinder compared to a screw compressor where their rotors are non-contact. The air produced is continuous and prevents the inlet and outlet valves opening and closing continuously, thereby reducing noise to significantly lower levels. Screw compressors are especially good in medium-scale and large-scale industries where there is a continuous requirement of air. These compressors do not prefer idle time and long periods of idle time, which sometimes causes issues. Rotary Screw compressor requires a higher capital investment, but provides better efficiency and faster ROI. There are 2 types of screw air compressor fixed speed and variable speed compressors, each having its own advantages. BAC’s screw compressors currently range from 7.5 hp to 60 hp, and also provide custom combinations for getting the best out of your investment.

What makes a fire pump different from other kinds of pumps?

by vemcoblogs -

Are you also amongst the ones who don’t find any difference between fire pumps and other pumps, primarily domestic water pumps?  Both pump water, don’t they? But they are as different as the scenarios they are employed in. And as the material and construction of fire pumps is different, they are far more costly than ordinary pumps.

So, before you go switching your fire pumps with domestic water pumps to control the cost, let’s take a look at the differences between the two:

  1. Corrosion-resistant- As we mentioned, both pumps are used in different situations wherein the fire pump is an emergency pump, rarely used in normal times. But all the time it is not in use, the fire pump still needs to be intact for whenever it is needed. So, a fire pump is constructed, keeping in mind to keep its corrosion resistance factor high- much more than that of an ordinary water pump. Like, water pumps have a cast iron material used in the construction of their impeller, compared to the pure copper or stainless steel impeller of fire pumps.  
  2. Fire pumps have to be fire-resistant- No matter how similar their applications might look, it is important for a fire pump to be fire resistant- something a water pump doesn’t need. A fire pump is not merely supplying water, it is used douse fires so, the material of the pump has to be metal and the surface of fire pump needs to a red paint coating, which not only stops it from getting rust but also fire-proofs it.
  3. High-temperature resistance- Fire pumps have to be high-temperature resistant as they may have to counter scorching heat in the event of a fire hazard, something ordinary pumps don’t have.  

Now that we have cleared the air of any lingering doubts and you are sure without a doubt that it is a fire pump you need, ensure that you approach the best pump dealers in Mumbai, Vijay Engineering and Machinery Company.
