What does the motor power of a compressor depend on?
Thread Content
May I ask, what factors are related to the motor power of a compressor? How to calculate it? Can the motor power be reduced by adjusting the backflow of a piston compressor?
Adjusting the motor speed can reduce the motor’s efficiency in performing work; does adjusting the return flow affect the working load of the compressor? It has no effect on motor power, in my personal opinion. .
It is mainly calculated based on the full-load power of the compressor and the conversion efficiency between the motor and the compressor; the thermal losses of the motor itself should also be taken into account. It has turned out that using a return line for the compressor does not help save energy; reducing the amount of air intake or adjusting the compressor’s clearance is necessary instead.
