It is called as positive displacement compressor because air is first sucked in a chamber and then compression is achieved by decreasing area of the chamber.
Reciprocating air compressor diagram.
Various compressors are found in almost every industrial facility.
A reciprocating compressor is a positive displacement machine that uses a piston to compress a gas and deliver it at high pressure.
The principle of operation is same in each type.
A reciprocating compressor or piston compressor is a positive displacement compressor that uses pistons driven by a crankshaft to deliver gases at high pressure.
So classification will help you better understand the working of the reciprocating air compressor.
Reciprocating air compressor has also classified according to its stages.
To understand the operation of an air compressor let us assume the cycle and indicator diagram for a simple single stage reciprocating air compressor as shown below.
But according to stages the building of discharge pressure is different in each compressor.
Reciprocating air compressor is a positive displacement air compressor in which air is sucked in a chamber and compressed with the help of a reciprocating piston.
It is called as positive displacement compressor because air is first sucked in a chamber and then compression is achieved by decreasing area of the chamber.
Reciprocating compressors have been the most widely used for industrial plant air systems.
