The Role of Air Compressor in Oxygen Cylinder Plant

Air compressors are used in numerous industrial applications, including healthcare products, food and beverages, petrochemicals, and nuclear power. Oxygen plants are industrial systems that are designed to generate oxygen, and compressed air plays a pivotal role in these. Typically, air compressors use air as a source of fuel, using pressure swing adsorption (PSA) or membrane separation techniques. Let’s take a closer look at the main types of air compressors that are manufactured and offered by ELGi.

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.
