Q: What is difference between screw compressor and piston compressor?

A:
1. Screw units adopt box-type structure, it is easy to install, while piston machine installation cost is higher;

2.screw unit has lower vibration and high operating efficiency, the piston unit consumes more energy than parameters;

3. screw unit needs to be replaced and maintained on time, the piston machine has many parts and high maintenance costs;

4. Screw unit adopts rotary operation, low noise, while piston units adopt reciprocating movement, it has high noise;

5. screw unit has higher energy efficiency than piston units, which is much more obvious when power exceeds 30p.
