Rotary Compressor vs Reciprocating Compressor

Sharing is Caring :)-

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

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
