EXPERIMENTS ON A TWO-STAGE AIR-COMPRESSOR. A reciprocating compressor or piston compressor is a positive-displacement compressor that uses pistons driven by a crankshaft to deliver gases at high pressure.. As the operating speed of compressors can be several thousand rpm, heat generated during compression cannot be sufficiently transmitted to the environment in such a short time. It then passes to through an intercooler to reduce the temperature in a constant pressure process by a counter current water flow heat exchanger. This video is unavailable. According to the technology, it can be devided to single stage air compressors and two stage air compressors.A single-stage reciprocating piston compressor works by drawing the air into the cylinder where it is compressed in a single piston stroke of approximately 120 PSI and then sent to a storage tank.
