Understanding Air Compressor Discharge Pressure

by vemcoblogs -

If you’re an air compressor owner, you must be acquainted with some of the basics of your equipment. Discharge pressure is one of the most relevant notions that significantly impacts how your air compressor performs. VEMC is one of the leading air compressor dealers in Mumbai, and in this blog, we take you through all you need to know about discharge pressure.

Definition and importance of discharge pressure

Discharge pressure simply refers to the air pressure at the output end, that is, the discharge flange of your compressor. Maintaining optimum discharge pressure is necessary to ensure maximum levels of efficiency and productivity. However, higher than required discharge pressure could cause wastage of energy as well as damage to the system. This is because of the rise in temperature leading to metal fatigue of valves and thermal stress on lubricants.

Factors affecting discharge pressure

Discharge pressure of an air compressor is quite dynamic and a number of factors affect it. Some of these are:

  1. Size and speed of the condenser fan
  2. Size of the discharge line
  3. Condition of the condenser coil
  4. Leakage of air
  5. Cooling effect by oil, water , etc.
  6. Rotational speed in case of a screw compressor
  7. Voltage and frequency of the power grid
  8. Suction temperature and pressure

Impact of discharge pressure on system performance and efficiency

For starters, discharge pressure directly impacts the air flow of a compressor, and the simple Boyle’s Law equation can substantiate this. 

P1 x V1 = P2 x V2

However, compressed air isn’t free and with every unit rise in discharge pressure, there is a proportionate rise in energy consumption as well. In fact, it is widely believed that for every 2-psi increase in pressure, the energy consumption increases by 1 percent. So while increase in discharge pressure does boost your performance significantly, it also reduces the efficiency due to overconsumption of energy. Besides, higher levels of discharge pressure can also cause leaks in the system and reduce the distribution of the compressed air, while reducing the lifespan of the air compressor in the long run.

Optimal discharge pressure settings for different applications

It is quite clear that operating an air compressor and deciding the right discharge pressure requires  some amount of nuance. There is no on-size-fits-all for every application that you use your compressor for. Industrial applications usually require a pressure of 100-200 psi while if you’re using the compressor for domestic use, anything between 90-150 psi should be enough. Pneumatic tools like nail guns require a pressure of 90-100 psi while sandblasters and spray painters would typically need 120-150 psi.

Discharge pressure seems to be a straightforward notion. However, to ensure you get the maximum out of your air compressor without wasting energy, you must operate it at the right levels of discharge pressure.

Why Air Compressor Dryers Are Essential

by vemcoblogs -
Air Compressor

Atmospheric air always contains a certain amount of moisture. When this air goes through rapid pressure changes through a compressor, this moisture precipitates as a condensate. This can be potentially harmful not just to your air compressor itself but also to your business operations. Moisture in your food processing or packaging business can encourage the growth of microorganisms, thus causing spoilage and quality concerns. Moisture also speeds up the process of corrosion in metallic parts leading to higher repair and maintenance costs. Vemc Is The Leading Air Compressor Dealer In Mumbai.

In This Blog, We Explain Why Air Compressor Dryers Are Essential And Which Type Of Compressors Suit Your Needs The Best:

  • The Need To Dry Compressed Air:

When air is compressed, the water vapour condenses and starts flowing into the pipes. The point at which the vapours start condensing is called Pressure Dew Point (PDP). This can cause serious issues with pipes and the connected equipment over a period of time, and thus the compressed air needs to be dried. This can be achieved by using either an integrated aftercooler or standalone drying equipment. 

Whether you use an aftercooler or augment your compressor with a standalone dryer depends entirely upon your business requirement. VEMC as the top Elgi Compressor Dealer in Mumbai can provide you with all the relevant information and also supply the equipment as per your need. 

  • Two Main Dryer Types:

As any compressor dealer in Mumbai will brief you, two main types of compressed air dryers are available in the market. Which one you choose depends upon your need, budget and business application.

  1. Refrigerant Dryers

This is one of the most cost-effective solutions to your problems. A refrigerant dryer provides air drying through cooling (as the name suggests). By cooling the air intensely, these dryers try to achieve the dew point at temperatures between 2-10 (C). This makes them highly energy efficient. Besides, the refrigerant gases used in equipment these days are more sustainable and environment-friendly. Get in touch with your nearest Elgi compressor dealer in Mumbai to know whether refrigerant dryers are right for your business operations.

  1. Desiccant/Adsorption Dryers

These air dryers are slightly expensive but at the same time more energy efficient and effective in removing moisture from the air. These work through a chemical process which binds to the moist air and removes it. These dryers can attain dew point at temperatures as low as -40(C). 

Conclusion

Following the right procedures to dispose of condensate is necessary for your business as well as the environment. The moisture often contains tiny oil particles invisible to the naked eye. These need to be removed using an oil/water separator. Otherwise, you could incur fines or penalties for violating environmental guidelines.

How to Use an Air Compressor: Things to Consider

by vemcoblogs -
Air Compressor

Air compressors are used for a variety of applications across industries. This is because of the enormous amount of power that compressed air generates. Compressed air when focused and channelised in the proper way can be used to accomplish tasks like cleaning, drilling, pumping etc. in an effective and efficient way. VEMC is the leading air compressor dealer in Mumbai and in this blog, we explain how best to use your air compressor.

Picking The Right Compressor For Your Needs:

It all begins with selecting the right compressor for your business operations. For instance, if you are using the compressor simply for cleaning tasks, a portable compressor without a tank will fully suffice. In case you wish to perform heavy-duty tasks, this obviously won’t be enough and you may have to look for a more powerful compressor. Likewise, you may also want to check out whether the reciprocating or rotary air compressor is better suited for your tasks. A quick call or visit to VEMC –– the authorised Elgi Air Compressor Dealers in Mumbai can help you choose better!

  • Getting started

Find the ideal position for your compressor. Make sure the floor is sturdy and can resist the load and vibrations from the compressor while it is at work.

  • Oil And Air Intake

Make sure the compressor has enough oil. Manually remove the oil cap and add the oil if it isn’t up to the specified mark. An adequate amount of oil keeps the compressor parts in good health by avoiding unnecessary friction.

Next, turn the switch on and fill the air tank. This should also get the PSI needle going. Set the PSI that you will be needing for the operation. Make sure the drain valve is tightly closed. Your nearest compressor dealer in Mumbai can definitely help you with these manual nitty-gritties. 

  • Moisture And Drainage

Moisture can speed up the process of rusting and corrosion, thus affecting the working life of your compressor. This naturally has implications for your maintenance, repair and replacement costs. Besides, moisture can also encourage the growth of microbes and cause spoilage of food or other sensitive inventory. Regular drainage of moisture is therefore necessary. This might call for some help from your nearest ELGi Air Compressor Dealers in Mumbai, but in most models, the drain valve is located at the bottom of the tank.

  • Power

Connect the air compressor to a three-pin power source. For your personal safety and to avoid damage to equipment due to high voltage, always make sure your compressor is grounded. As much as possible, avoid using extension cords and instead use an additional air hose to increase your reach. This is because extension cords can cause your compressor to overheat.

  • Meeting All Safety Regulations

Use goggles and closed-toe shoes to protect your eyes and feet from impact while using an air compressor. To ensure the safety valve is functioning properly, test it by tugging on it before use and listening to the air escaping.

Five Mistakes Not to Make When Choosing an Industrial Air Compressor

by vemcoblogs -

Choosing an industrial air compressor for a specific application is an important task. It is a seminal step, and although it can be complex, it is crucial to get right for smooth operations. Here are five mistakes that are necessary to refrain from making when selecting an air compressor:

Choosing the wrong compressor technology

There are several different compressor technologies in the market including centrifugal, screw, piston, and scroll compressors, and making the right choice best can be confusing. Here’s a guide to help you select the one that fits your requirements best.

  • Piston compressors are ideal to operate in a relatively smaller space where the daily hours of running are low and duty cycles are shorter. If you are looking for a compressor in these conditions that comes with an affordable initial cost, this may be the right compressor for you.
  • Screw air compressors are highly energy-efficient, make less noise, and are easier to maintain. If your tasks are going to need long duty cycles, and the number of hours of running each day will be higher, these can be suitable for you.
  • Scroll air compressors make minimal noise and maintain a fully oil-free environment. They are appropriate for use in places like hospitals and universities.

Picking the wrong compressor size

Selecting the right size for the compressor is crucial for efficient operations. It helps to know the exact measures of operating pressure and the flow of volume in the air compressor for your processes. This will then help you determine the correct size that you need the air compressor to be.

Ignoring your air quality requirements

The application of the air compressor may have a standard air quality requirement. For example, in pharmaceuticals, you may need the air quality to be completely oil-free, while in other industries, the rules may not be as stringent, such as in manufacturing. You can consult an air compressor expert for help with identifying yours.

Not considering the lifecycle costs of the compressor

When choosing an air compressor, bear in mind that a majority of its lifecycle costs are due to energy consumption. This is why it is important to choose a machine that is energy efficient for use in the longer term. Don’t make the mistake of underestimating the total lifecycle cost of the air compressor.

Going with the wrong service provider

Choosing the right compressed air service provider is as important as choosing the right air compressor machine. Make sure to go with a reputed provider that not only supplies OEM parts but also offers quality maintenance and emergency support.

Follow the above tips and avoid costly mistakes when selecting an air compressor!

Oil Lubricated Screw Compressors

The range of oil-lubricated air compressors from ELGi equips you with long-lasting and cost-effective compressed air solutions. An air compressor that is oil-lubricated draws air into a storage tank with a screw that requires oil in order to keep the production process running smoothly. They are relatively quieter than other ELGi air compressors and have long durability.

ELGi’s collection of oil-lubricated rotary screw air compressors have optimal profitability and make for efficient installation with its reliable design, advanced technological features, and sheer manufacturing excellence.

Why should you choose ELGi’s Electric EG Series of screw air compressors? 

The Electric EG Series of screw ELGi air compressors are known for their oil carryover of less than 1 PPM. In fact, this range has the lowest oil carryover in the industry and comes with 6 years of uptime warranty on Air End, and 3 years of uptime warranty on the Motor and Air oil separator.

Up to 85% of a compressor’s cost is from energy consumption, cost of spares, cost of service, warranty, and downtime. ELGi aims to minimize this 85% impact by offering high-efficiency motors with high flow capacity air ends that offer more airflow for the rated power.

Additionally, ELGi offers in-built Variable Frequency Drives (VFDs) and standalone VFDs that help regulate airflow as per demand, which reduces power consumption.

Air Accessories

It is important to note that compressed air is not pure. The compressed air contains naturally occurring impurities that could have a negative effect on the end application. Common contaminants of compressed air include dirt, water, bacteria, and other particles, and sometimes, even the degraded and residual lubricating oil. When these mix together, they may form an acidic sludge which is likely to increase the wear and tear of the end applications. For increased reliability and energy savings, you must make sure that the compressed air is absolutely clean and dry.

ELGi provides an array of accessories that ensures that application-specific air quality norms are met as per ISO 8573 standards. Contact your local ELGi dealer and ELGi compressor distributor for the air compressor and air accessories that are best suited for you.

5 Steps to Achieve Maximum Air Compressor Efficiency

by vemcoblogs -

The key to optimal air compressor efficiency is to maintain the integrity of your entire pneumatic system. This includes the air compressor, fittings, air hose, and tools. An efficient pneumatic system will ensure that you’re getting the air you need when you need it. An inefficient one will cost you time and money. So, here are 5 steps that will make sure your pneumatic system keeps operating the way it was intended to.

  1. Use 3/8-inch Air Hose: Whenever possible, use a 3/8-inch air hose to ensure you get the maximum amount of pressure to the tool. While a 1/4-inch air hose is lighter to work with, its smaller diameter restricts airflow and causes a greater degree of frictional loss. As a thumb rule, opting for a larger diameter hose ensures the maximum amount of pressure to the tool.
  2. Use Shorter Lengths of Air Hose: The longer the distance air has to travel, the greater is the loss of pressure. For the maximum amount of pressure, use shorter lengths of air hose wherever possible. This, however, may not be possible in certain unavoidable situations, and in that case, using an auxiliary tank can come to your rescue.
  3. Use an Auxiliary Tank: An auxiliary tank acts as a reservoir of extra air and allows a user to maximize the distance between the compressor and the tool. It also helps minimize frictional loss.
  4. Lubricate your Pneumatic Tools Regularly: Using lubricants on movable parts can reduce friction and achieve greater levels of efficiency. It is important to consider the frequency of lubrication as well as the type of lubricant being used in the tools. For tools that are used daily, 4-5 drops at the start of each shift, is the norm. Using the wrong type of lubricant can damage the O-rings and other critical components.
  5. Check the System for Leaks: This can be done simply by allowing the compressor to build top pressure with the air hose and other components connected. Once the compressor has stopped pumping, watch the tank pressure gauge and listen carefully for any hissing noise. If the needle of the pressure gauge drops continuously, it indicates a leak. If on the other hand, it stays put and there is no hissing noise, the system is completely leak-free. Leaks in the system can cause excessive running of the compressor, leading to early wear and tear. A leak can be detected by spraying soap water on the hose and other components and looking for the formation of bubbles.

Different Types of Air Compressors

by vemcoblogs -

Compressed air is a great source of energy in wide-ranging industrial operations and is used for powering tools like impactors, drills, and other equipment. Air compressors, therefore, act as engines to create and supply this powerful driving force. Compressors are prone to falling into disrepair, especially due to impure, humid, or hot air, and therefore require regular maintenance, care, and protection to ensure optimum level performance.

Different types of air compressors are used in the industry, each with unique designs and operation specifics. So, you must understand the difference between all of these air compressors. Buying the right type of compressor from a reputable company ensures a longer lifespan and higher returns on your investment. In this blog, we shall take a look at the most common types of air compressors in use today.

Reciprocating Air Compressor

A Reciprocating Air Compressor, also known as a Piston Compressor uses one or more pistons to compress the air which enters it through a system of valves. The compressed air then flows into the holding tank. This is one of the most widely used types of industrial air compressors and finds application in areas like chemical processing, gas transmission, and hydrocarbon refining.

Screw Air Compressor

Screw Air Compressors make use of two closely meshing helical screws to compress air. Once the air enters into the chamber, the helical screws are turned to push it down into an extremely constricted space, which increases its pressure manifold. These compressors are mostly used in refrigerators and automated manufacturing systems. In the construction sector, these are used to provide compressed air to jackhammers, riveting tools, pneumatic pumps, sandblasting operations, and industrial paint systems.

Centrifugal Air Compressor

A centrifugal compressor makes use of a fast-rotating impeller and radial blades which create centrifugal force to suck the air in. These days, centrifugal compressors have high-speed electric motors to drive the impellers and create powerful centrifugal force. These compressors are used in gas turbines, automobile turbochargers and superchargers, oil refineries, natural gas processing, air-conditioning, and HVAC systems.

Oil-Free Scroll Compressor

Air compressors have a number of moving parts which create friction and wear and tear, leading to early degradation of the compressor. As such, oil lubrication is a must for air compressors. However, frequent oil lubrication can be burdensome and may not be suitable in operations where cleanliness is of utmost importance. Oil-free scroll compressors can come in handy in such situations. These use the rotary movement of scrolls to compress air into a very small space and pass it through the air outlet located at the centre of the scroll.

Maintenance for Air Compressor Systems

by vemcoblogs -

Maintaining air compressor systems is simple but very important! It requires combating heat, moisture, and loss of air pressure, to ensure peak levels of performance and also prevent early degradation of the compressor system. Heat causes motors, bearings, and oil to break down while moisture can affect the internal parts of the compressor by corrosion and microbial growth. Loss of air pressure makes the compressor do more work for the same volume of compressed air. So, in order to ensure the smooth running of operations, avoid interruptions and unexpected downtime, it is crucial to maintain the compressor at regular intervals. In this blog, we take a look at the measures that need to be taken.

Maintain the Coolers and Filters

  • Heat being the number one enemy of compressors, it is extremely important to keep the intercoolers and aftercoolers clean. These cool the air between the stages and after compressing the air respectively. 
  • It must also be ensured that the oil cooler is working properly. This is mainly responsible to prevent the degradation of oil and reduction in its life with rising in temperatures. Regular testing of the compressor oil is an important maintenance practice to predict the breakdown of oil before it becomes problematic.
  • The air inlet must be kept safe from dust, dirt, and contaminants. Regular replacement of air filters is very effective in keeping the air compressor clean on the inside.

Remove Compressed Air Condensate

  • As air is compressed, it ejects excess water that it cannot hold. In the humid spring season, this water could gush into your distribution system while in winters it can freeze inside the system and damage the piping. Clogged traps and stuck open valves must be regularly checked to ensure the removal of condensate from the system.
  • It’s important to check the drain valve regularly to ensure only clean and dry air is coming out. Any presence of moisture indicates retention of the condensate in the compressor and must be treated immediately to prevent corrosion and fungal and bacterial growth inside the system.

Avoid Compressed Air Pressure Loss

  • It is essential that the air pressure is maintained at the level suitable for your operations. Any drop in the pressure means the system is not operating at peak efficiency vis-à-vis the consumption of energy.
  • Change the inline filters and point of use filters as soon as they reach saturation. It is recommended that these elements are changed when the indicator reaches 6-8 PSI. Besides the filters must be inspected twice a year to ensure that they haven’t been compromised.
