Why is my air compressor not working?
An air compressor problem could stem from one of many issues, such as an air leak, an oil leak or a broken part. In some cases, you might have insufficient pressurization or air flow. In other cases, the compressor might fail to start up or stop running as prompted.
What happens if the check valve fails open in a reciprocating compressor system where a pressure switch and unloading valve are used?
The air compressor unloader valve provides a critical function in preparing your air compressor to restart. If the unloader valve has failed when the motor tries to start quite often the motor will lug (struggle) to start and typically a breaker will trip or a fuse will blow.
What causes pressure switch failure?
A high reading means the pressure switch has failed. Check for a clogged hose port or cracked hose running from the draft inducer motor or condensate collector box to the pressure switch. These problems can cause the switch to trip or fail.
How do you know if your unloader valve is bad?
Water leaks and inconsistent behavior are also signs of a potential failure in the near future. González: The typical signal when there is an unloader malfunction is a reduction of flow through the nozzle, which results in pressure loss. Dean: Typical symptom of an unloader failure is a sudden smooth pressure loss.
What is a delayed unloader valve?
unloader valves- (EV) and delayed unloader valves (AEV) Air compressor applications particularly reciprocating compressors, often use what is called an unloader valve. The delayed unloader valve, on the other hand, additionally assists the motor when starting in that it remains open until a certain pressure (approx.
What happens when there is no pressure in an air compressor?
When there’s pressure build-up in the cylinder, it forces the pressure valve to open. This action leads to compression of atmospheric air. Without the pressure valves, air will lose the pressure to flow through air lines into the compression tanks.
What to do if your compressor does not unload?
Compressor does not unload. Check if pressure switch is correctly set and working. Check inlet valve and loading solenoid for good operation. If the safety valve is located before the oil separator, check differential pressure of oil separator.
What causes a compressor to shut down at high temperature?
Compressor shuts down on high-temperature. If your compressor trips on over temperature, it could be any of the following: Ambient temperature too high or not enough ventilation. Too low oil level. Wrong type of oil. Dirty oil cooler. Thermostatic valve not not working. Dirt / obstruction in oil lines.
