5 Benefits of Regularly Changing Compressed Air Filter Elements

by vemcoblogs -

The enormous amount of focused energy that compressed air is able to produce is used for a wide-ranging set of activities. These include drilling, combustion, metalwork, filtration, chemical processing and moulding. While performing these operations, plenty of dust and particulate matter could get stuck in the compressor. In the short run, this impacts the performance of the compressor, while over the longer horizon, it could even affect its longevity due to wear and tear, or over-exertion. Air filters are therefore necessary to maintain the health and performance of your compressor.

Why air filter elements must be changed regularly

A compressed air filter typically has a coalescing filter, a dry particulate matter element or both. The former is used to pull and cohere water droplets or oil from the air while the latter helps trap dry particulates and microbes. Both use removable filter element. This is because in a typical industrial setup, these filters are under serious strains due to pressure and temperature fluctuations, corrosive chemicals, varying air speeds, extreme humidity etc. These require a change at regular intervals.

Let’s understand in detail the 5 benefits that arise from regular replacement of air filter elements:

1. Safety

By regularly changing your air filter, you’re committing yourself to particulate-free air on the factory floor. This will protect your employees from exposure to dust particles and microbes, where air compressors are being used for air conditioning. Besides this will also prevent accidents from unwanted overheating or system malfunction.

2. Cost control

By replacing the air filters regularly, you are reducing the risks of sudden breakdown and also the costs associated with it, such as downtime and expensive repairs. A saturated air compressor which doesn’t have a fresh air filter has to work harder causing more wear and tear, and also consuming more energy.

3. Efficiency

By enabling easy flow of air through your compressor, fresh air filter elements are highly useful in ensuring greater efficiency and productivity in your facility. The adsorption dryer beds for instance can work with maximum efficiency when new filters are used.

4. Boosting longevity

Filters are generally manufactured using borosilicate glass. If air filters are not replaced regularly, this glass can develop tiny holes causing accelerated contaminant flow. Overall, the regular replacement of air filters can help in ensuring longevity of the compressor system as it helps avoid the mechanical wear and tear, damages and corrosive glitches.

5. Reassurance

Having regularly replaced air filters can give you and your employees a sense of reassurance that the environment of the factory floor is safe, and the air is healthy to breathe. There are also lesser chances of breakdown and downtime, which could be a cause of serious business loss.

Piston Vs. Rotary Screw Air Compressors: Which One to Choose?

by vemcoblogs -

Air compressors have diverse applications for a wide range of businesses. Two of the most popular and widely used compressors are piston and rotary screw compressors.

Piston, also known as reciprocating compressors, find maximum use in the automotive service industry such as gas stations, tire stores, and general service shops, due to their price and availability. However, rotary screw compressors can be a suitable alternative as they offer better performance and require less space.

In this blog, we will understand the various points of difference between the two to help you choose the right one for your business.

Duty Cycle and Flow

Duty cycle is the time (calculated in percentage) a compressor can operate for, without getting overheated or causing wear. The allowable duty cycle for most piston compressors is 60-70%. Most piston compressors are oversized to allow space for the compressor to shut down and cool off due to the high temperatures. This may cause capacity problems during peak operating hours.

Modern rotary screw compressors, on the other hand, have in-built aftercoolers with huge surface area and robust fans to bring down the air temperature leaving the compressor.

Oil Carry-over

When pistons, cylinders, valves, and rings experience wear and tear, the quantity of air goes down. This causes more lubricating oil to seep through the piping into the usable parts. This is known as carry-over.

Piston compressors usually pass more oil than rotary screw compressors. Rotary screw compressors experience lesser oil seepage in comparison because the rotors don’t come in contact with each other and hence, don’t wear. Moreover, the compressor fluid also acts as non-wearing sealant that’s captured, filtered, cooled, and recirculated.

Energy Efficiency

For service industries that use compressors as large as 30 hp, energy efficiency becomes an essential factor to save electricity costs.

Piston compressors usually deliver 3-4 cfm per hp whereas rotary compressors deliver 4-5 cfm per hp. This shows that rotary compressors deliver more air per unit of input energy.

Maintenance

The maintenance of piston compressors is more expensive than screw compressors because the frequency of maintenance and the number of spares is significantly higher for piston compressors. However, the advantage is that any semi-skilled technician or worker will be able to perform the maintenance service.

Noise Levels and Vibration

Traditional piston compressors produce a lot of noise and vibration. As a result, they are mostly placed in separate rooms or outside. However, the immediate ecosystem directly affects a compressor. For example, a hot and humid room will increase the compressor temperature, reduce its shelf life and make it difficult to remove moisture and oil from compressed air.

Rotary compressors cause lesser noise and vibration. They also don’t need to be kept in separate rooms or sealed to the floor, offering more flexibility with their location i.e., well-ventilated areas.

How significant is it to evaluate the right financial model for solar power system?

by vemcoblogs -

Making the shift to solar power can be beneficial for your business, especially, cost-saving in the long run. However, before you can go green, there are a lot of technicalities to take care of.

When you’re considering shifting to solar power, you’ll find two models in the market: the capital expenditure (CAPEX) model and the operating expenditure (OPEX) model.

In this blog, we will be discussing the two models in detail to help you reach an informed decision.

The CAPEX Model

In this type of financial model, the client approaches VEMC to install a solar pump system on the premises owned by the client. After the commission of the system, the ownership gets transferred to the client and VEMC’s scope ends. Hence, in this type of model, the client pays for the installation of the plant, and the ownership too rests with the client.

Some of the advantages of this model are:

  • The client gets to have complete ownership of the plant and its operation
  • Based on the capacity of the solar plant, the client can save sizeable margins on electricity
  • The client can earn several subsidies and taxes from government bodies, for example, the central finance assistantship (CFA)
  • The client can be partially immune to rising utility electricity prices
  • Industrial and commercial clients can get accelerated depreciation benefits as well

The OPEX Model

In the OPEX model, the investor invests in the project and the client only pays for the power he consumes. The amount of consumption is agreed upon in a contract known as the Power Purchase Agreement (PPA).

What is PPA financing?

The Power Purchase Agreement (PPA) covers the contractual terms of the solar plant and the individual roles of the parties involved. There are usually three parties involved in such a contract – the investor, the installer, and the end client. VEMC is usually the installer for most of the clients. The investor invests in the solar plant and the client buys all or part of the power they want to consume at a rate that can be fixed or changed with time. VEMC installs the plant as per the investor and client’s approval and takes ownership of the plant’s annual maintenance. The client can terminate the agreement after payment of a certain amount or buy the plant directly from the investor.

Choosing the right financial model for your solar investment will depend on your budget and purpose. If you have the resources to take all the responsibility for the installation and maintenance of the plant, CAPEX will be a good choice. But if you don’t have dedicated personnel to look after the systems, OPEX can be a good option for you.

Buying a Swimming Pool Pump? Here’s what you need to know.

by vemcoblogs -

A swimming pool pump passes the pool water through the pool filter and sometimes, a pool heater. A pump is effective when it passes the water through the filter once every 12 hours, also known as a turnover. The effectiveness is measured through the size of the pool and the turnover rate. It’s calculated by the gallons per minute (GPM) of water it passes.

What is a swimming pool pump?

It’s a common part of swimming pools that allows you to pump water through a filter, circulate it, and keep it clean. It’s an important component that ensures the pool water is cool and safe to bathe in.

Do I need a swimming pool pump?

Traditionally, pools were cleaned manually with skewers. While this helps remove large particles such as leaves, it’s not as effective for cleaning fine debris such as dust, sand, or dirt.

A swimming pool pump is ideal for cleaning the debris at the bottom of the pump to render the pool water dirt-free and ideal to swim in.

What are the key parts of a swimming pool pump?

A basic swimming pool pump has five different components. They are:

  • Water inlet – This allows the pool water to enter the pump. The diameter of the inlet directly impacts the flow rate of the pump.
  • Water outlet – The water exits the pump from this area. Again, the diameter of the outlet dictates the flow rate of the pump.
  • Filter – This is an important component since it captures the debris before the water re-enters the pool. They are also known as sand filters or strainer baskets and are built from high-quality, erosion-resistant plastic.
  • Impeller – This spinning component propels the water out of the pump. It sucks the water into the impeller face and expels the water through the side.
  • Motor – The motor is the force that runs the impeller, draws water into the pump and again out of it.

How does a swimming pool pump work?

At the heart of a good swimming pool is an effective pump. It circulates the water, disperses the treatment chemicals, and prevents the water from stagnating. It achieves this by pulling the water through an inlet, passing it through the filter, and then pumping it back out into the pool.

Why choose Kirloskar KPP swimming pool pump?

This is a high-performing pump that works silently.

It can be used for water circulation and filtration in various systems such as:

  • Hot springs
  • Swimming pools including suction sweeping
  • Spas
  • Water treatment systems
  • Landscape fountains

Bird droppings and nesting on solar panels causes loss of efficiency by 2%. Ways to avoid it.

by vemcoblogs -

Solar panels are an effective and environment-friendly choice for your commercial spaces, to cut down on harmful pollution. It not only helps the planet, but also enables energy efficiency in a sustainable way. However, since the panels are located outdoors, they may attract various outside elements such as birds. Many people are unsure about whether solar panels hurt birds or vice versa.

In this blog, we discuss in detail about the relation between birds and solar panels.

Solar panels and birds

It’s common knowledge that birds may find a good nesting ground in your solar panels and may soil your gutters and panels. What should you do about it? And how should you save the birds as well as your solar panels? Let’s learn more.

Do solar panels benefit birds?

This may come as a surprise but solar panels benefit birds. Currently, some of the primary sources of electricity are oil, coal, and natural gas. They cause carbon pollution in the air and form a layer in the atmosphere that traps heat. Apart from various issues around global warming, it also leads to birds having to find alternate homes. Hence, solar panels are beneficial to birds as they provide them and their young ones with warmth and shelter.

Do solar panels attract birds?

Yes, just like windows, solar panels have reflective surfaces, and such surfaces usually attract birds.

Do solar panels kill birds?

Solar panels don’t kill birds directly. The reflective surfaces of solar panels often resemble water when birds are flying above. The appearance of moving water makes them dive, which eventually hurts them and sometimes, kills them.

Do birds harm solar panels?

Solar panels usually have space between the panels and the roof that allow wiring and ventilation. The shade in these spaces is ideal for birds to take shelter.

Birds usually build nests here as well as leave droppings, broken eggs, etc., under the space available. When these accumulate, they reduce the airflow needed to prevent solar panels from overheating. They can also flow into the gutter, leading to blockages and foul odour. It can also collect on top or under the panels and it’s best to get them cleaned as soon as possible.

Damages from small critters

Critters such as squirrels also enjoy nesting under solar panels and may cause harm by chewing on exposed wires. This could lead to solar panels running inefficiently.

Another serious concern is that nesting materials such as leaves, debris, and chewed wires may also lead to fire hazards.

How to protect your solar panels from birds?

There are several options to look at:

  • Wire Mesh – Building a wire mesh along the edges of the solar panel can help stop birds from nesting under the system. This can also prevent the accumulation of debris.
  • Roof Spikes – They don’t necessarily hurt birds but make it difficult for them to nest.
  • Plastic Predators – Decoys are a great way to ward off birds since they can’t differentiate between artificial and real birds. Like scarecrows, an owl with a swivel head can be very effective in scaring birds away.

Importance of Solar O&M

These various factors can affect the output of your solar panels. Proper operation and maintenance can enhance the lifespan of these systems. The frequency and degree of maintenance of solar systems depend on the installation type, system configuration and location of the setup. You can choose from various types of services such as performance monitoring, preventive maintenance, and corrective maintenance.

VEMC, one of the top solar companies in Mumbai, provides solar panel installation in Mumbai. VEMC provides solar O&M services as well.

A Short Guide to Moisture Control in Air Compressor Systems

by vemcoblogs -

It’s not uncommon for moisture and condensation to accumulate in your compressed air systems. Hence, you need a solution that can help prevent excess condensation in your compressor, especially if you’re in an industry that demands 100% moisture-free condensed air.

Why does your air compressor contain moisture?

Moisture is a natural by-product of the compression process. It just extracts the moisture that already exists in the ambient air.

Some of the common causes of moisture build-up in compressors are:

  • Equipment damage – When the internal parts of compressors wear out, it leads to moisture build-up. This causes the machine to lose its power to extract air as well as heat up, leading to more moisture build-up.
  • Environmental factors – Humid conditions also cause the machine to take in more moisture leading to more condensation.
  • Pressure on the compressor – When your compressor is strained beyond capacity, it gets heated up further more. This is especially the case with piston compressors, which heat up more when used for longer periods of time.

Why is excess moisture harmful?

Excess moisture hampers the workings of your air compressor. Some of the consequences of excess moisture are:

  • Rust and corrosion – Build-up of water in your compressors can lead to rust in and corrosion of the machine and pipes.
  • Damage to pneumatic controls – The machines that rely on pneumatic controls suffer from severe damage when there is moisture build-up inside them. That can result in rust and scale build-up.
  • Rapid wear and tear of production equipment – Moisture can cause the lubrication inside compressors to wash away. This causes metal components to wear away faster.
  • Damaged circuits and in-line filters – In-line filters help clean particles and oil from your compressor. Moisture increases pressure in the machine and reduces the filter’s efficiency.
  • Contamination – Moisture can damage end products, valves, and motors. It can easily contaminate solvents, lubricants, and food products.

How to eliminate excess moisture from your compressor?

Some of the solutions you can try out to remove moisture build-up from your compressors are:

  • Install an air dryer – An air dryer works in tandem with an air compressor to remove moisture. There are four common types of air dryers: refrigerated dryers, desiccant dryers, membrane dryers, and deliquescent dryers.
  • Get a piping system – Piping systems are one of the most cost-efficient systems. In these setups, the metal pipes absorb heat to bring down the air temperature, and can be a good solution for office buildings.

6 Air Compressor Maintenance Tips to Avoid Breakdown

by vemcoblogs -

Air compressors of all makes and models require varying degrees of maintenance. Whatever the model or quantity of compressors you use for your operations, it’s essential to regularly inspect the parts and service them, whenever necessary. Failure to perform routine maintenance on your compressors can lead to early failure or expensive repairs.

Air Compressor Supplier Johor Bahru (JB), Rotary Screw Compressor Supply Malaysia, Air Receiver Tank Suppplies ~ JCompressor Services Sdn Bhd

Here’s a short guide on how to keep your air compressors running at full capacity:

1. Drain your air receiver tank

Use the drain and plug at the bottom of the compressor to drain the air from the compressor’s air receiver tank. Collection of air in the machine leads to the accumulation of water and moisture while the machine is running, especially during summer, when humidity is higher. The moisture gets collected in the receiver tank and if not drained regularly, it can lead to corrosion of the receiver tank and piping. An automatic and a manual bypass drain during daily inspections is ideal.

2. Inspect the hoses

Hoses are often the most vulnerable parts of compressors because they need to be strong enough to transfer air between the machine and the final point, which can put a lot of strain on them. Checking your hoses on a weekly basis is extremely important. Cold weather also affects hoses — it causes them to crack or corrode and hence leak. Routine checks are ideal for keeping the hoses clean and leak detection devices are ideal to find the leaks.

3. Alter the air filter

Air filters usually trap a lot of junk. The filters are designed to bear a heavy load, without which, a lot of impurities will accumulate and degrade the performance of the compressor. This contamination is critical for industries such as food and beverage, hospitals, and labs. Air filter inspections should be done regularly, especially in dusty conditions.

4. Clean the intake valves

The intake valves of an air compressor must be clean to function fully. When compressors are put to constant use, dust particles and other elements get sucked into the vents. Cleaning the vents at least once every three months is essential.

5. Change the oil

The compressors that run on oil need the oil to be changed regularly as well. Fresh oil helps run the various parts of the engine smoothly. Especially in humid conditions, the oil loses its viscosity and fails to lubricate the different parts.

6. Get it inspected by a professional service team

Allowing a professional service team to regularly check leaks and perform preventive maintenance and required repairs, can offer a lot of peace of mind. Scheduling this regular maintenance can help save time and money in unnecessary breakdown repairs.

Keeping your air compressors healthy and functioning smoothly is essential and possible through regular maintenance. VEMC is an authorized ELGi air compressor dealer and provides end-to-end solutions for all your industrial energy requirements.

Why is it important to understand the difference between gauge and absolute pressure?

by vemcoblogs -
Difference Between Gauge and Absolute Pressure Measurement

Pumps and similar systems are built in a way so as to generate and retain pressure. In gas-based systems such as air compressors, the pressure is fairly low. This is because gasses when compressed incessantly makes air molecules huddle nearer to each other in the application of energy. This pressure doesn’t extend to the tubes or chambers of the compressed air systems.

In brief, pressure can be defined as a force acting over a certain area. It’s most commonly measured in pounds per square inch (psi).

There are multiple systems to measure pressure. Two of the most common ones are absolute and gauge pressure. There are quite a few differences between the two that have considerable impact on their use and measurement. Once the purpose behind measuring pressure is identified, the next step involves choosing which system to use: gauge or absolute pressure. This is a crucial decision since choosing the wrong system can severely impact the accuracy of measurements.

The pressure inside a compressed air system is comparatively lower. Hence, even minor deviations such as 10 psi or 20 psi can lead to major operational issues.

Here are the differences between the two systems in great detail:

Gauge Pressure

It’s one of the most commonly used systems of measurement and uses atmospheric pressure as its base value. So, any chamber will equalize based on the atmospheric pressure, when vented. This makes it easy for calculations and tests since the atmospheric pressure doesn’t have to be subtracted.

Also known as effective pressure, gauge pressure is signified by BARG or BARE and PSIG or PSIE.

Absolute Pressure

Comparatively, absolute pressure is used less frequently, since it signifies zero pressure or a perfect vacuum. A good example of the measurement of absolute pressure can be that of barometric pressure.

Absolute pressure is commonly signified by BARA and PSIA.

Choosing the right system: gauge or absolute pressure

The most fundamental difference between gauge and absolute pressure is that gauge pressure uses atmospheric pressure as its base or zero point whereas absolute pressure uses absolute zero as its base or zero point.

So, if the idea is to measure a type of pressure influenced by atmospheric pressure, it’s best to use a gauge pressure. It will help measure the pressure minus the atmospheric pressure. This is the system used to measure the output of pressure of air compressors.

Again, if the idea is to measure a type of pressure not influenced by atmospheric pressure, absolute pressure is used as a reference. An example of this can be leak testing a sealed container.

What type of piping is needed for my compressed air system?

by vemcoblogs -

Compressed air systems find use in various industries such as construction, automotive, metal-work, and wood-work. Tools used in these industries require compressed air to run and since they don’t need motors, they are lightweight and handy to use.

Compressed air systems work best when air is released from the system at the right pressure, volume, and consistency. These systems can run the risk of miscalibration which robs them of their power and leads to rust and debris build-up in the pipes.

This makes choosing the right air compression system as well as its parts integral to their efficient functioning. Pipes are one of the most critical components in a compressed air system and defective and inefficient pipes can often lead to loss of power. Moreover, obstructions and blockages, moisture build-up, and sharp angles can also affect the pressure of compressed air systems negatively.

Paying proper attention to the size, layout, installation, and maintenance of pipes used in compressed air systems is a prerequisite to ensuring their powerful performance. Two materials usually go into making pipes: plastic and metal. Of these two, metal pipes are the preferred choice for compressed air systems.

Here are some of the common types of metal pipes used for compressed air systems along with things to consider when choosing them:

  • Black steel pipes are the most commonly used ones because they are strong and durable. However, it can be time-consuming to install them and they are also susceptible to corrosion. There’s also the risk of the threaded connections slipping and leaking.
  • Another widely used type is galvanised steel pipe. They help solve the corrosion problem. However, in some cases, the galvanised coating can come off and cause blockages in the air flow.
  • Copper pipes come with a lot of advantages. They are free from corrosion from condensation and are easy to cut and weld. They are lightweight and come with a wide range of fittings to choose from. Their smooth interior means that they can sustain solid laminar flow. However, they can be a bit expensive since they require time and skill to install, especially the threading and soldering bit.
  • Aluminium pipes can also be a good choice since they are lightweight, durable, and anti-corrosive. They’re also easy to install and maintain than other types. The only downside is that it can be as expensive as copper.
  • Stainless steel pipes are corrosion-free, both from the inside and outside. Moreover, they are easy to weld and press. However, they can be heavy and the material cost can be on the higher side.

How often should I change the oil in my pump/piston?

How often should I change the oil in my pump/piston?

Air compressors need to be in optimum condition to give the best performance. Maintaining them properly ensures that they last long and help save money in the long run. There are several maintenance routines to consider for a smooth-functioning air compressor. One of the most important routines is changing the oil in the pump or piston of the air compressor. While focusing on other maintenance routines, many people overlook this one, which often leads to poor performance of the air compressors and, in some cases, also causes damage to the systems.

Why is it important to change the oil?

The oil in a compressor has several functions apart from lubrication. It helps the compressor parts to cool down so that the motor doesn’t overheat. The oil also acts as a sealing agent during the compression process.

If the compressor doesn’t have enough oil, it may not perform as efficiently as it’s supposed to. Low oil levels cause the compressor to overheat since air compression produces heat and oil absorbs the heat. Moreover, low oil levels also increase friction, which can lead the compressor to overheat. It’s also important to replace the contaminated oil from the air compressor regularly. Failing to replace the old oil with new oil causes debris and particles to build up and hampers its smooth functioning. Lack of sufficient oil can also increase the chances of rust, wear and tear, and corrosion. Finally, oil has a tendency to oxidise in the presence of water and heat. This reduces its effectiveness which can lead to costly breakdowns.

In some systems, overheating leads to an automatic shutdown. In such situations, the compressor can be used again only after it has cooled down and the oil has been replaced.

How often should the oil in an air compressor be changed?

Air compressors need consistent lubrication to prevent friction on the pumps or pistons and hence, the oil level must be checked regularly. The frequency of changing oil in compressors depends on the type of compressors used. Some compressors need more frequent changes than others and it’s best to consult the user manual that comes with the system. It’s possible to even find the life expectancy of some oils in terms of service hours in some of the manuals.

For rotary screw compressors, the oil should ideally be changed every 2000 hours or 12 months, whichever is earlier. For reciprocating air compressors, the oil needs to be changed every 3 months.

Performing an oil analysis that checks for important factors such as viscosity, particle count, water contamination, and total acid number (TAN) can help determine when to change the oil. It’s ideal to conduct an oil analysis every 500 to 2000 hours, depending on the user manual and the warranty.

Solar Success Story

VEMC, a 72-year-old solar power company in India, has played an integral role in helping companies transition from electrical to solar energy. It has helped companies adopt smart solutions in solar power and taken over the end-to-end execution as well. In this blog, we take a look at how VEMC helped install solar rooftop systems and inverters on the industrial rooftop of Caravan Logipark Pvt. Ltd. and executed the project successfully. The site is located in Koproli, Uran, in the state of Maharashtra. The building authorities were looking to reduce their energy consumption and substitute it with a renewable source of energy.

Challenge

The main challenges arose during the excavation work for AC cabling. The first step was to trench the road where there was already a lot of vehicle movement. Next, the cable had to be placed and sand and bricks had to be filled on the top or bottom of the cable. During the final termination phase, the grid had to be shut and the connection terminated. However, there was cold storage which couldn’t be shut for more than 15 minutes; otherwise the food stored will get spoilt. There was also a dearth of continuous light and so, it was arranged source like DG for cold storage.

Our Solution

VEMC steered the success of this project with effective time, cost, quality, team, procurement, and communication management. One example of this was during the excavation work for AC cabling. The team took the smart decision of trenching half the road first and installing the cables, and then taking up the other half. This ensured that vehicle movement wasn’t hampered. Moreover, the team worked at a stretch during shut down and ensured the DG was loaded at the same time as the grid shut down.

Safety Measure During Execution

VEMC ensured the execution of the installation was done with all safety measures in mind. Some of the measures taken were:

  • Avoiding the use of mobiles or electronic devices during the installation
  • Using crane and forklift managed by trained experts for unloading of modules and limiting the speed to 10 km/hr
  • Constant training of installation staff to avoid any damage to modules
  • Thorough checking of cable for damage before the cable routing process
  • Limiting the speed of the boring machine within 10 km/hr during the earthing process
  • Use of cotton, PVC, and leather gloves while fixing electrodes, handling backfilling compound, and connecting the electrical panel
  • Use of welding goggles, face shields, and aprons during the welding system

Our post-installation feedback revealed that the client had savings of 4-5 lakh units of electricity monthly from this system.

SP Coupled Pumpset With IE5 Motor — The Ultra Premium Efficiency Pump

by vemcoblogs -

Kinetic pumps propel large volumes of fluid at low pressure, while positive displacement pumps move relatively small volumes of fluid at high pressure. Before further pressure or velocity can be increased, a certain level of pressure is necessary to get the fluid to flow into the pump. Cavitation (the creation of a void space in the pump that is typically filled with liquid) will take place if the inlet pressure is too low. Cavitation is frequently caused by the vaporization of liquid in the suction line. A greater pressure zone causes the vapor bubbles that were brought into the pump with the liquid to collapse, which causes excessive noise, vibration, corrosion, and erosion. The necessary inlet pressure, the capacity against a specified total head (energy per pound owing to pressure, velocity, or elevation), and the % efficiency for pumping a certain fluid are crucial features of a pump.

What is an SP Coupled Pumpset with IE5 motor used for?

  • Handling mild chemicals, effluents, sewage, ashwater, etc.
  • Handling flood and rainwater. foundation, trench, and pit drainage
  • Water pumping from ships, ports, and docks. removing stored water from parking lots, roads, and basements, etc.
  • Cooling water for shovels, piling equipment, and marine motors.

If your business has any of the above needs, you should consider contacting industrial water pump dealers in Mumbai to help you out.

Why go for a SP coupled pumpset with IE5 motor?

  • They function with extremely high efficiency, leading to more productivity with lesser energy consumption.
  • Lower operational costs and lower life cycle costs.
  • For the same amount of fluid to be pumped, up to 16.5 percent less energy is required.
  • They contain superior F-Class insulation.
  • Strong construction to handle significant power fluctuations ensures the equipment’s dependability, safety, and longevity.

Does Colour Play a Role in the Way Solar Panels Function?

by vemcoblogs -

Solar panels are designed to absorb incoming solar radiation and use it to generate electricity. It is recommended that we shift our electricity needs from other non-renewable sources to solar energy as it is renewable, relatively safe for the environment, and cheaper to maintain. With the help of solar software, which has increased the effectiveness and usefulness of solar electricity, solar power is now widely used in utilities, businesses, homes, and other applications. It is interesting to note that majority of solar panels are dark blue and black in colour. However, coloured solar panels are also gaining in popularity. So, which colour solar panel is the best for you to buy?

Choosing the right solar panels for your project

Comparing two types of coloured solar panels

First, let’s compare the two most common types of solar panels- black monocrystalline and blue polycrystalline. Black coloured panels are more energy-efficient than blue coloured panels. This means that they require fewer solar cells to absorb larger amounts of solar energy. The advantages of this would be increased solar power generation and conservation of space. Black solar panels also come with a 25-year guarantee and so are well worth the investment. Blue solar panels on the other hand are priced lower and have a relatively low maintenance cost. It therefore can be said that monocrystalline (black) panels are more efficient than polycrystalline (blue) panels, however, this efficiency comes with higher costs. Furthermore, considering environmental factors, blue-coloured solar panels create less waste and generate a lower carbon footprint.

Other colours of solar panels

Other colours of solar panels are available mainly for aesthetic reasons. For example, green-coloured solar panels are recommended for areas surrounded by greenery as they can blend into the surroundings well. Similarly, some buildings may require solar panels of a colour similar to the colour of a building as black or blue panels could be distracting against a building of a contrasting colour. It is true that coloured solar panels come with higher prices and are less efficient. However, solar technology is rapidly growing, and efforts are being made to increase its efficiency and make its availability cheaper.

What are the Basic Reciprocating Compressor Components?

by vemcoblogs -

A reciprocating compressor or piston compressor uses pistons that are aided by a crankshaft. The main function of the reciprocating compressor is to increase the level of pressure in gases.

A reciprocating compressor has several components that aid in the passage and compression of the gas. Each of these components plays a specific role and is equally necessary for the smooth functioning of the reciprocator compressor. 

Let’s take a closer look at the basic components of a reciprocating compressor:

Frame

The frame or crankcase is a sturdy structure that encloses all the rotating components. ELGI air compressor frames are square or rectangular shaped. In Integral Compressors, the frame is fitted to both the compressor and engine-powered cylinders which are driven by one crankshaft. 

Cylinders

Cylinders play a crucial role in containing the air that needs to be pressured. A compressor could have either large low-pressure cast iron cylinders or small high-pressure steel compressors. Cylinders help to keep the reciprocating compressor cool during the compression cycle. Reciprocating compressor dealers might also show you cylinders with replaceable liners that can be changed when damaged or worn out.

Distance piece

The distance piece is an intermediary component that attaches the low-pressure cylinders to the frame of the compressor. Due to the distance piece in ELGI air compressors, the cylinders can be detached if required. A distance piece could have a single, double or extra-long compartment arrangement. 

Piston

The piston is what compresses the gas within the cylinder. It is typically made up of a strong and heavy material that does not react with the gas in the chamber. You might find pistons made from aluminium or cast iron when looking for compressors at reciprocating compressor dealers.

Piston rings

Piston rings are placed around the piston. These rings could be either metallic-like bronze or non-metallic like a fluorocarbon compound. They are subject to friction as they come in contact with the inner walls of the cylinder and might wear out easily. Piston rings might have to be replaced regularly but help to protect the piston from damage due to friction. 

Cross head

The piston is inserted into the cylinder bore with the help of a cross head. Narrow pistons used with a cross head are more efficient as they can accomplish longer strokes. 

Crankshaft

This is what drives the piston. It is attached to the electric motor shaft on one end and to the piston on the other. Higher powered crankshafts are made of forged steel while those operating less than or equal to 150kW are made of ductile iron.

Connecting rod

The connecting rod connects the crankshaft to the piston and enables its upward and downward motion. The connecting rod is typically made of the same material as its corresponding crankshaft.

Valve

The valves of a reciprocating air compressor ensure that the gas flows in only one direction. On one side of the cylinder, there are inlet valves while on the other there are outlet valves. Valves are of three types:

  • Ring valve
  • Poppet valve
  • Plate valve

Bearings

Bearings complete the structure of the reciprocating compressor. They ensure the proper radial and axial positioning of components of the compressor including the crankshaft, connecting rod, and cross head.
