Rotary Compressor vs Reciprocating Compressor

Today we will learn about rotary compressor vs reciprocating compressor. A compressor is a device which takes atmospheric air or other gases, compresses it and delivers the high pressure air or gas to a storage vessel from which it may be conveyed by a pipeline to wherever the supply of compressed air required. These are classified mainly into two types. The first one is known as reciprocating compressor and other one as rotary compressor.



The main difference between rotary and reciprocating compressor is that the rotary compressor use an  impeller which is in rotary motion to compress the gases while a reciprocating compressor involves a piston cylinder device in which gases are filled and they compressed due to upward movement of piston. There are many other parameters on which they can be differentiate. These are as follow.

Rotary Compressor vs Reciprocating Compressor:


S.No.
Particulars
Reciprocating Compressor
Rotary Compressor
        
1. 

Suitability

These compressors are suitable for low discharge of gas at high pressure.


They are suitable for large volumes of gas at low pressure.
    
2.

Operation Speed


Low operational speed.


High operational speed.
          
3.

Gas Supply

Pulsating


Continuous
         
4.

Balancing

Cyclic Vibration occur.


Less vibration due to rotary mass.

         
5.

Lubrication system

It contain complicated lubrication system.

Generally simple lubrication compare to reciprocating compressor.

       
6.

Quality of Gas delivered


Generally contained with oil.


It supply clean gas relatively.
       
7.

Size

It has large size.

Rotary compressor comparatively small for same .discharge.

          
8.

Free air handle


250-300 m3/min


2000-3000 m3/min
          
9.

Delivery Pressure


800-1000 bar


Below 10 bar
      
10.

Process

It involves generally isothermal compression.


Rotary compressor involves isentropic compression.



This are all main differences between rotary compressor and reciprocating compressor. If you have any query regarding this article, ask by commenting. If you like this article, don’t forget to share it on your social networks. Subscribe our website for more interesting articles.
