Refrigeration piston compressor

Refrigeration piston compressor: Single-stage piston compressor; Two-stage piston compressor.

Refrigeration piston compressor

Standard type: The unit consists of compressor, motor, coupling, and control board, which are mounted on one base.

Perfect safety protection

Exhaust pressure super-high protection   Oil pressure difference ultra-low protection

Automatic by-pass safety valve  Anti-liquid hammer gas valve 

1. With CAD optimized design, gas valve has small resistance and long service lifetime.

2. Advanced shaft seal structure and material are reliable and durable.

3. Main machine frame is made by high accuracy machining center, which improve the movement accuracy.

4. Needle bearing with cage of high pressure connecting rod has high accuracy and long service lifetime.

5. Piston ring is monolithic cast, no elasticity attenuation.

6. With high phosphor and electric spark quench, wear resistance of cylinder sleeve is good.

7. Checked with dynamic balance, the crankshaft has the features of good balance and small vibration.

8. With flexible coupling, the equipment has the features of high efficiency, energy saving, and self-alignment.

9. With capacity control, the compressor can start up without load and operate with partial load, so electric power is saved.
