You know Air Compressors are classified in different types. The principle of operation is same in each type but according to stages,the builiding of discharge pressure is different in each compressor.In this post i will describe general working of a Reciprocating Air Compressor.The reciprocating type compressor consist of a piston which is enclosed within the cylinder & equipped with suction & discharge valves.
The piston recives power from main shaft through crankshaft and connecting rod.A flywheel/beltwheel is fitted on the crankshaft which is driven by electric motor or diesel engine.It supply uniform motion through out the cycle of operations.
The compression of air is done by first drawing a volume of air into its cylinder through suction valves during suction stroke by the piston & then compressing & discharging it on the return stroke of the piston through delivery valves.
This simple working is used in every Reciprocating Air Compressor.
Find details of each type of reciprocating air compressor in comming posts.
Bye till next post.
