How do I troubleshoot rotary screw compressors?

Troubleshooting rotary screw compressors doesn’t have to be overwhelming. By identifying common issues like insufficient air pressure, oil carryover, or high energy consumption, and taking proactive steps to address them, you can keep your system running smoothly and efficiently.

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 you troubleshoot a compressor?

Troubleshooting Steps Start with the basics: check the power supply. Ensure that all connections are secure and that the voltage matches the compressor’s requirements. A multimeter can be helpful here to test the circuit. Next, reset the circuit breaker or motor overload protection.

What happens if a rotary screw compressor uses too much oil?

Excessive oil consumption in a rotary screw compressor is more than just a minor inconvenience—it’s a costly issue that can impact the efficiency and lifespan of your system. When a compressor uses more oil than expected, it’s essential to identify and address the root cause to avoid escalating operational costs and potential downtime.

Why is my rotary screw compressor overheating?

Solving insufficient air pressure is critical for maintaining productivity and avoiding further system stress. When a rotary screw compressor begins overheating, it’s a clear sign that something is amiss. High operating temperatures can lead to inefficiencies, system shutdowns, and even long-term damage to critical components.

Why do rotary screw compressors make noise?

By addressing excessive oil consumption promptly, you can save on operating costs and ensure your compressor performs at its best. Rotary screw compressors are known for their smooth and quiet operation, so when you hear unusual noises or feel excessive vibrations, it’s a sign that something isn’t right.
