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.
A reciprocating compressor is a positive displacement machine that uses a piston to compress a gas and deliver it at high pressure.
A reciprocating compressor or piston compressor is a positive displacement compressor that uses pistons driven by a crankshaft to deliver gases at high pressure.
But according to stages the building of discharge pressure is different in each compressor.
So classification will help you better understand the working of the reciprocating air 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.
Various compressors are found in almost every industrial facility.
Reciprocating compressors have been the most widely used for industrial plant air systems.
Click the image to enlarge the simple reciprocating air compressor has a piston which reciprocates inside the cylinder wall and cylinder head.
The principle of operation is same in each type.
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.
The intake gas enters the suction manifold then flows into the compression cylinder where it gets compressed by a piston driven in a reciprocating motion via a crankshaft and is then discharged.
