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.

Applications of Screw Air Compressor in the Paper and Textile Industry

by vemcoblogs -

Air compressors are used widely across all industries. They serve a variety of purposes in the least possible time. The capacity and capabilities of a screw air compressor depend upon its usage and applications. Screw compressors are usually large due to their capacity to receive the air. The larger the size of the tank of the compressor the greater is its capacity. The engine size of a screw air compressor is larger than a normal compressor to successfully carry out various functions. The power consumption of a reciprocating air compressor is large. It requires a considerable amount of energy to function and serve various purposes.

Following are some of the applications of screw air compressor in the paper and textile industry:

  1. Spinning: One of the major functions of an Elgi air compressor is spinning. A screw air compressor is used in paper and textile industries for spinning. A screw air compressor also helps in a ring, air-jet spinning as well as open too. A screw air compressor makes it easy to spin the textile and achieve the desired outcome.
  2. Texturing: In the paper and textile industry, one of the major concerns is the texture of the final product. A screw compressor is used at various stages in a factory to get the perfect texture of the product. In this process, yarn is intermingled with the help of a nozzle and the jet. The pressure generated during this process helps one to achieve the texture required.
  3. Air-jet weaving: the modern technique of air-jet weaving is popular for its swift results and perfect alignment. A screw air compressor is used to blow a yarn with weft transportation. This is one of the most crucial stages; it requires technical expertise and complete know-how to ensure the yarn is blown optimally while using the right combination of machinery and industrial equipment.
  4. Pneumatic conveying: A screw air compressor is used for pneumatic transport and allied works. The screw air compressor is extensively used for fabric and PET chips. They ensure flawless performance and provide optimum results in the least possible time. 
  5. Man-made fibre production: A reciprocating air compressor is used for the production of partially oriented yarn (POY) and fully oriented yarn (FOY). The air compressor enables faster production of quality yarns. However, the size of the screw compressor depends upon its application and production capacity too.
  6. Garmenting process: There are several processes involved in the production of the garment. Some of them include printing, stitching, marking, cutting, laying, and much more. An air compressor can be highly useful in streamlining the process and scheduling the production too. A screw compressor optimizes the process of production. Therefore, it is widely used in the textile industry. 
  7. Dyeing textiles: Screw air compressor helps one to transfer a yarn to spool or cone for dyeing and other purposes. Compressed air is used for dyeing purposes and dyes the fabric/textile with the planned colour. 
  8. Packaging: The screw air compressor is used to wind the yarn and package them as per one’s needs. Packaging plays a very important role whether it is textiles or paper. The wrap beams and air compressors are used together for packaging purposes and wrapping too. Compressed air is also used for sizing the paper and textile products.
  9. Combing: Combing is the process of removing impurities and short fibres with the help of rollers and brushes. The screw air compressor can make this difficult task much easier and organized. One can get a pure version of output with minimal efforts with the help of the screw compressor.
  10. Treating wastewater: One of the most important parts of production is managing wastewater and wastage. Whether it is the textile industry or paper, it is imperative to efficiently plan wastewater treatment to get rid of the impurities optimally. The screw air compressor can facilitate wastewater treatment with utmost efficacy.

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.

So, if it is centrifugal pump you seek, VEMC stands by its promise to provide only the best to you as the renowned distributors of the reliable Kirloskar pumps, making it one of the best pump dealers in Navi Mumbai, Mumbai and Raigad Districts

Incidently we are also the Master Distributor for process pumps for entire West and Central zone.

Happy pumping as it is a way of Life at VEMC

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.

But when it comes to Vijay Engineering and Machinery Company, you can rest assured that you will be given the best service by one of the trusted pump dealers in Mumbai, who are renowned for providing a wide range of high-quality Kirloskar pumps.

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.

If you are in search for a reliable and professional supplier of Reciprocating or Screw Compressors, you can contact Vijay Engineering And Machinery Company – the Authorised Distributors of Elgi Compressors and Spare Parts.

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.

Factors to Consider When Choosing Gate Valves

by vemcoblogs -

Gate is one of the most used valves when opening and closing the flow of liquid from a straight medium line. The gate valves are usually found in different places. Instantly they are found in the irrigation areas and can be used in different plantation areas in regulating various fluids.

Valves are essential components used in the pumping systems in diverse industries. Some of the main functions of the valves is preventing backflows, regulating the direction of flow as well as regulating the system pressure, the UL /FM approved gate valves may sometimes be dismissed as secondary considerations while designing different faucets at your home. This is necessary because they increase the performance of the systems minding their efficiency, longevity, and safety. This article, therefore, will discuss the critical factors you should ‘put into consideration while selecting the gate valves.

The type of valve used:

The water faucets at home are mostly made of valves with handles used in regulating the flow in it. The valve, therefore, should be designed with a gate as well as an actuator. The actuator is usually made of level, electric motor or a handwheel. Each of these creates the anticipation of regulating the performance that makes the valve useful in given conditions. Therefore, the gate valve is regarded as a piece of metal that determines the passing and non-passing of the flow.

Actuation Method

It is necessary to consider the operation of the valve. Therefore you need to determine if the valve is manually operated by hand or it will require an actuator for turning it on and off automatically. If you settle on the latter, then you decided on the unit that will be used if it will require, pneumatic, or hydraulic actuator. There are other several Gate Valves Ul/Fm Approved and used in different industries with electric motors. Therefore, it is necessary to determine the functionality of the gate valve.

Maintenance Requirements

Maintenance should be done regularly; the gate valve requires maintenance to ensure they do not clog. Hence, this is the simplest method of providing the gate valves to serve you for a long time. The gate valves are designed in a way that makes them easy to clean without having to disconnect the end cups from the pipe. This, therefore, prevents the line from shutting done during the maintenance process. The most common uses valve the wedge valves that are parallel, the valves are utilized highly because they easily overcome the contraction and expansions in the climate that fluctuates regularly.

Application Conditions

Selecting the right gate valve for application in the essential factor when choosing a correct valve for your application purpose. When the valve is not appropriately sized, it may lead to operational issues within the valve or in the system. This also determines the temperature, flow rate and pressure that the valve operates with. However, metal valves in most sentences withstand the high temperatures as well as the pressures as compared to the plastic ones.

Valve Function

Before installing the valve gate, always consider determining the need of the valve. They are typically used in on and off controls, diverting as well as media mixing. Also, consider if your valve will be open or closed. When you want to increase the life expectancy, you should consider the order value in the orientation as well as the changes on different valves.

Finally, there are diverse factors involves when selecting the right UL /FM approved gate valves for your application. It is essential to seek the help of qualified engineers to help in analyzing the critical factors as well as in understanding the application requirements. This will; be essential in finding the right gate valve for your application.

Various reasons for a centrifugal pump not discharging water

by vemcoblogs -

When centrifugal pumps produce inadequate flow, not only is the pump’s efficiency compromised, but the entire system suffers a gradual breakdown until the problem is solved. But often, we put the entire blame of the low flow on the pump itself, misdiagnosing problems in the system as pump problems only but to solve issues related to the performance of the system one has to look at the bigger picture.

Reasons for a centrifugal pump to produce a low flow of water

  1. A clogged suction pipe: If a suction pipe is riddled with debris, there is less flow into the pump, which in turn leads to less flow out of the pump.
  2. Worn impeller, ring, and plate: If the vanes on the impeller, the ring, and plate have worn down, the hydraulic capacity of the pump is hampered.
  3. Reversed Impeller Rotation: Often, a pump’s motor is bump started without first ensuring whether the pump is hooked up for proper rotation of the shaft. So, when the motor turns in the wrong direction, the shaft is pushed back by the impellor which nat damage the internal surface of the pump.
  4. Excessive Clearances: Excessive slip may occur if the clearances are too wide for the type of fluid pumped causing the fluid to recirculate inside the pump, thus causing the lower flow.
  5. Debris in the impeller: The hydraulic capacity of the impeller is sometimes removed by the debris clogging it, creating an area of low pressure.
  6. Open Bypass Valve: Sn open bypass valve may be the one diverting the flow isn’t somewhere else.

But you don’t have to worry about under performing centrifugal pumps or water pumps not working adequately as you have the best pump dealers in Mumbai, Vijay Engineering and Machinery Company at your service.

How to select the right pump for any chemical process?

by vemcoblogs -

As the name itself suggests, chemical pumps are used in the process of making, using or disposing of chemicals. The materials used in their construction and designing are chosen in a way that they can withstand substances with high or low levels of viscosity, abrasiveness, and corrosiveness. 

When something is so susceptible to the state of the substance flowing through its interiors, it becomes crucial to be as accurate as possible during its selection. When it comes to zeroing on the correct chemical centrifugal pumps, there are many variables one has to keep in mind:

-The materials used for the construction of the pump

The materials used should be compatible with the chemical media as acids like sulfuric acid and hydrochloric acid may cause problems like corrosion.

There are two types of pump materials- metal and nonmetallic. Metallic chemical pumps are mostly made from stainless steel, a nickel alloy or titanium for protection against corrosion. Nonmetallic pump materials are rubber, plastic, ceramics, glass, etc. which are all used as pump materials for corrosive materials.

  • Pump size

If a pump of incorrect size is picked up, it will lead to operating problems within the pump fluid transfer system. Although owing to a built-in safety factor, mostly pumps are slightly oversized but if a pump is too big, it can make the centrifugal motor to be lightly loaded during operation. This, in turn, leads to lower productivity and higher operating costs. 

There are other issues that crop up as well like premature bearing failures, excessive vibration, increase in operating temperature and cavitation issues. But that doesn’t mean that one should go for an undersized pump as it has its own share of consequences. In an undersized chemical pump has to pump faster, straining their pump components, bringing down their suction capabilities, as well as fastening its wear, which may lead to failure.

  • Pump performance specifications

The proper performance of the pump includes maximum discharge flow, maximum discharge pressure (head), inlet size, discharge size, and media temperature.
