The gas compression apparatus consists of two commercial compressor receiver units each with added temperature indicators, flow indicator, power meter and pressure indicating controller. The compressors are of similar power demand but different design. Pressure, temperature and flow data obtained can be used to calculate compression efficiency. Control valves are provided to provide control of the downstream pressure.
Function of Compressor Trainer Single and Duplex Compressor
The gas compressors use air as the working fluid to demonstrate reciprocal compressor operation. Trainees select compressor type and flow rate then read and record the flows and temperatures for further analysis. The discharge pressure is automatically controlled to a selected process pressure set point.
