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:
