Behavior of A Piston Compressor
CS-510
Test stand for piston compressor from refrigeration open process with air typical open two-cylinder compressor drive via asynchronous motor with frequency converter for speed adjustment
Inlet pressure and outlet pressure (pressure ratio) adjustable via valves instruments: flow meter, sensors for pressure, temperature, speed, torque (via force) data acquisition via PLC, access to stored measured values via Ethernet
