working of reciprocating compressor

But according to stages, the building of discharge pressure is different in each compressor. (Tom) Dahmen As the piston moves downward (towards BDC), the air from the atmosphere enters into the chamber of the cylinder. Today we’re discussing how these compressors work. A reciprocating compressor is employed for compressing a small volume of air or gas to a relatively high-pressure ratio. The compression process may be isothermal, polytropic or isentropic. This motion is enabled within the device using pistons. For example, corner compressors are the most common type of compressor units, since they have com… The piston starts doing to and fro motion inside the cylinder.

The crankshaft is connected to the electric motor directly by coupling or by belt and driven by the pulley arrangement. Example: The cylinder of a single-suction compressor. The hermetic type of compressor may be either reciprocating or rotary and is a direct drive unit with both motor and the compressor hermetically sealed with in the housing. 7. The compressor working principle involves the reciprocating action of a piston inside a cylinder, which compresses air / gas inside the cylinder. At the end of the delivery stroke, a small quantity of air, at higher pressure, is remained at the top surface of the cylinder. Here, we will discuss about single stage air compressor. The compressor automatically adapts to the current load. - Trunk design As power is On, the electric motor starts rotating and also rotates the crankshaft attached to it. Then the cooled air is compressed in the high pressure cylinder.
