Introduction of the Rotary Screw Air Compressor

Introduction of the Rotary Screw Air Compressor

Rotary Screw Air Compressor works by trapping air between two interlocked rotors and decreasing the volume of that stucked air and its moves down to the rotors when the volume of compressed is reduced then used as a powerful tool and for numerous other applications. There are many uses of air compressor in industry wise also.

History of Rotary Screw Air Compressor.

There is a big history of Rotary Screw Air compressors. The Rotary screw air Compressor was before called twin rotary screw compressor and developed in 1980.

So Why Have They Named Twin Rotary Screw Compressors? 

Twin Rotary Screw Air Compressor

There are two-element are present in the rotary compressor which is a male and female element. The twin element in the compressor rotated in opposite direction in the Rotary screw air compressor. The Air fills a space between the two rotors squeezing or compressing the air into smaller space.

Reciprocating Air Compressor vs Rotary Screw Air Compressor. 

There are many types of air compressors like reciprocating air compressors and also called piston air compressors. This air compressor’s job is to take compressed air in a smaller space and then compress it to a receiver tank. The Reciprocating air compressor is more expensive than another compressor. That’s the reason everyone chooses the rotary air compressor. A rotary screw air compressor is worked by compressing the air between two rotors and giving adequate pressure.

Reciprocating Air Compressor Parts.

Air-End

The heart of the air compressor is the air end and it is made of lots of components.

Mainly air end is just one part of an air compressor system and the air is compressed oil will enter the air end through an inlet valve then the oil is subsequently separated from the compressed air. Not only air Air ends many additional Components are needed to make a rotary screw air compressor work.

What Are the Other Common Components?

Air Filter

The Compressed air enters the compressor and that’ll affect the longevity of the air compressor system. So always remember about a suited air filter is needed for airflow in an air compressor.

The air filter can be scaled directly to the compressor or mounted and attached to an air input hose. The location of the filter should be considered as cool clean air.

Separator Tank Primary.

The primary separator tank is when compressed air leaves the filter and is mixed with compressor oil. This mixture enters Separator Tank Primary in the first step to separate the oil from the occurred air.

Primary Separator Tank uses automatic separation and centrifugal force to Force the oil molecules together. At this stage, a large amount of oil removed in this stage and the separator tank also acts as an oil reservoir.

Separator Tank Secondary.

The secondary tank Separation filter compresses when the air leaves the primary tank. This is oil-free and the remaining oil mixed with the air when coalescing filter air entered the Separator Tank Secondary. This Filter has a membrane material that collects the remaining oil particles. Then the remaining oil particles extend the oil around into the primary oiling method.

Oil Filter

Air Filter

It must contain an oil filter because it has a closed-loop oiling system. The main job of the oil filter is to gather any loose particles collected from the entry of the air compressor system.

Oil filters may be located in different locations called compressors, mounted rollers, or separator tanks.

So These are the points you want to know about Rotary Screw Air compressors.

Comparing of Rotary Screw Air Compressor vs Reciprocating Air Compressor

Do you have any idea about these two standard air compressors? Yup, that is a Rotary screw air compressor and Piston or reciprocating air compressor. In this blog, we will show the comparison and performance of the Rotary screw air compressor and Reciprocating air compressors.

Everyone in the business field has this major question in their mind Should I buy a Reciprocating or a Rotary screw? Mutually both of the compressors create compressed air but it depends upon the application so we will explain it briefly.

What Is the Dissimilarity between the Reciprocating Air Compressor and Rotary Screw?

Both of the compressors produce compressed air utilizing positive displacement, These compressors compress air mechanically to reduce its volume but the mechanics or engine is different.

Reciprocating Air Compressor

Reciprocating air compressor

This air compressor is also known as a piston air compressor.

Pistons were used in the mid-1600s, Now these are largely used in industry, and Similarly, the same compressor was used during the 1800s 

The reciprocating air compressor engines are systematic and easy to maintain. They are adequate for applications.

Rotary Screw Air Compressor

Rotary screw air compressor

Rotary screw air compressors have been about since the mid-1900s. There are two rotors and a compressed air system present in the Rotary screw air compressor.

The air is pulled into the chamber and squeezed into a smaller space. The rotors turn and are continuously compressed in this process. There are a few moving parts in the rotary screw air compressor and mainly this air compressor is more reliable.

Which Is the Best Reciprocating Compressor or Rotary Compressor?

Reciprocating or Rotary doesn’t matter and it’s all depending upon how the compress is used? How much compressed you need and the environment is also part of it.

Mainly you want to know about the pros and cons of Reciprocating or Rotary compressor

How Does Elgi Rotary Screw Air Compressor Work?

Elgi Rotary screw air compressors work a positive displacement process and that includes air pulling into a chamber. Compressed air is made by reducing the volume in the chamber. Rotary screw air compressors particularly use positive displacement with spiral screws.
  • The screws allow a hydraulic seal to compress the air. The most common rotary screw air compressor and the steps are
  • The first step is air entering the machines through the inlet valve. Perfectly, that will clean the air of unnecessary dust but you want to keep the machine in the right place.
  • The next step is air will move into the pressure controller line and It goes through the regulator valve, which sets the air pressure.
  • To combine into a mist, oil and air move into the compressor.
  • The air compressor travels the machine’s rotary screws.
  • Then an air and oil mist exists in the air compressor and enters into the oil separator tank.
