The reason for the screw air compressor to stall

Why does my rotary screw compressor keep shutting down?

Here’s What to Check It’s one of the most annoying compressor problems: the unit powers up, starts running, and then shuts right back down. Whether you’re using a reciprocating compressor, a portable rotary screw, or a stationary rotary screw, this issue usually comes down to power, load, or airflow problems.

Why does my air compressor stall after startup?

When these types of compressors stall out seconds after startup, it’s usually something electrical or mechanical: things you can troubleshoot quickly without pulling the manual. Breaker or Wiring Issues – A weak power supply or loose wiring may allow the motor to start, but not stay running.

Controller Alarms – Look for alarms related to phase loss, overloads, or motor temperature.

What happens if a compressor stalls?

A rotating stall may develop into a surge. The choking occurs in the compressor which operates at a low discharge pressure and maximum flow rate. It is the limit of the performance curve, at this point velocity of the impeller reaches a velocity of sound of the gas at that condition within the compressor (Mach number reaches Unity).

How do I know if my rotary screw compressor is bad?

Check the voltage when the compressor is running. If the voltage drop significantly when the compressor starts/runs, you have a bad connection somewhere. Check all relays, fuses and electrical connections. Common rotary screw compressor problems and issues that have been reported. Get help with the most common problems for rotary screw compressors.
