6 FAQs about [Screw air compressor delayed unloading]

Why does my compressor trip on over temeprature?

If your compressor trips on over temeprature, it could be any of the following: Ambient temperature too high or not enough ventilation. A screw compressor can run loaded ('pumping air') or unloaded ('idle'). The inlet/loading valve opens and closes according to air demand.

How does a screw compressor work?

A screw compressor can run loaded ('pumping air') or unloaded ('idle'). The inlet/loading valve opens and closes according to air demand. The inlet valve is controlled by a solenoid valve that supplies control air to the inlet/loading valve. Check solenoid valve coil and solenoid valve operation.

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.

What happens when a compressor lubricant sump is blown down?

The added capacity will push the system pressure up until the unload setpoint is reached. When unloading, the inlet valve closes and the compressor lubricant sump is blown down, producing zero flow but keeping the compressor running at about 30% of full load power. Fig. 1.

How do you control a compressor at part load?

A moderately efficient method of controlling a compressor at part load uses load/unload mode with adequately sized storage receiver capacity. With this mode, a pressure switch, or electronic control, is used to provide load and unload signals to the compressor.

How do you load a compressor?

Load/unload — Loading and unloading a compressor using inlet valve control and sump blowdown. Moderately efficient if the compressor has access to large storage. Variable displacement — Opening up ports in the screw to bypass the compression element. Good efficiency if set up correctly.
