Advantages of Reciprocating Compressor Over Screw Compressor

ELGi Screw Compressor

Before choosing an air compressor, it is very important to consider the features of each type to ensure suitability for your business operations. Screw air compressors operate by using two screws that trap and compress air between them while reciprocating compressors operate using pistons in a cylinder. While both find utility across industrial operations, reciprocating air compressors have some remarkable advantages over screw compressors. VEMC is the leading Air Compressor Dealers In Mumbai.

In This Blog, We Take You Through Each Of These Advantages In Detail:

Better Control Over The Discharge Pressure

Reciprocating compressors are typically used to discharge pressure of up to 12000 psi. They can be used at atmospheric pressure and to some extent even in a slight vacuum.

Reciprocating Compressors Operate At Higher Efficiencies

An Elgi Reciprocating Compressor can generate greater pressure but operates at much less energy.

Lower Installation Cost

As any air compressor dealer in Mumbai will tell you, reciprocating air compressors have a low initial setup cost as compared to other compressors. 

Low Noise Level

The piston pump of a reciprocating air compressor is quite straightforward and moves up and down rapidly to compress air. With its simple design and operation, the friction levels are quite low which in turn also results in lower noise levels.

Longer Service Life

These compressors have high durability and can serve sturdily for a much longer period of time than screw compressors. If proper upkeep is ensured, a typical reciprocating compressor is estimated to serve for a total of up to 50000 hours.

Easy Maintenance

Due to the simple design and operation, the maintenance of reciprocating air compressors is quite easy and cost-effective. Technicians have easy access to most components of the compressor and spare parts are also readily available in the market.

Versatility

These compressors are great to use in both light as well as heavy-duty operations. These can be tank-mounted or base-mounted which reduces the placement constraints and boosts ease of use. Besides, these air compressors have both oiled and oil-free varieties and can thus be put to use in a wide range of operations. This is especially useful if you function in restaurants, food processing or the pharmaceutical industry and are concerned about oil contamination. 

Better Efficiency In High-Pressure Applications

Reciprocating air compressors are known to perform much better in high-pressure applications. This makes them most beneficial when intermittent use with high pressure is required.

Better Variable Load Situation

Reciprocating air compressors are better suited for variable load situations. These can be controlled using variable-speed drives, bypass recycling, step-less methods, and clearance pockets. 

Better For High-Pressure Pulsations

Unlike screw compressors, reciprocating air compressors are very good at handling high-pressure pulsations both in terms of energy efficiency and generation of air pressure.

How to Use an Air Compressor: Things to Consider

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.

What Size of Industrial Air Compressor do I Need?

One of the most challenging decisions while buying an air compressor is sizing it. This is necessary for maximum efficiency and involves a number of parameters such as CFM, pressure, application, layout, etc. While sizing an air compressor may seem simple on the surface, it is determined by a host of factors to ensure optimum performance. As we are one of the leading Air Compressor Dealers in Mumbai.

In This Article, We Can Take You Through All Of These That Shape The Sizing Decision Of Your Industrial Air Compressor:

Size of your project

Quite simply, bigger the size, more will be the power generated. Whether you need your air compressor for heavy-duty construction work or office work will be the primary determinant of your sizing decision. Besides, if you need a constant flow, it will be better to invest in a large-sized air compressor as small compressors are not able to generate it.

Your tools and applications

Next, you’ll have to consider the work you’re going to perform with your air compressor. Air compressors have wide-ranging applications from drilling to sand-blasting. Choosing the right size for the right task is critical to ensure effectiveness. All tools have a required flow or CFM which should be matched with that generated by your air compressor. An ELGi Reciprocating Compressor is a great option for both light and heavy-duty use.

Your source of power

A standard domestic voltage should be enough for most compressors to work. But for larger industrial compressors, a 240-volt source is necessary. Where electricity isn’t available, compressors can also be powered with petrol. Since your source of power acts as an important constraint in the functioning of your compressor, take it into serious consideration before choosing one.

Space available

If you’re trying to buy an air compressor for your garage startup, there’s very little hope that a large industrial compressor will fit in there. Given the paucity of space in the city, most air compressor dealers in Mumbai will emphasize on the space constraint as the number one factor to size your compressor. Besides, if you’re going to move the compressor frequently, a smaller and lighter one will always be the better choice to avoid inflating your carriage and labour bills.

Size of the tank

The size of the tank is the most important factor that decides the size of an air compressor. This is significant because it determines how long you use the compressor before it needs to refill the air tank. If your tools and applications require a constant flow, a bigger air compressor is the right choice. Smaller tools like nail gun require short bursts of compressed air that don’t need a large tank. But the motor will have to switch on and off, which can cause wear and tear, and affect the lifespan of your compressor overall.

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.

5 Steps to Achieve Maximum Air Compressor Efficiency

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

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

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.
