6 FAQs about [Diesel screw air compressor unloading valve]
What is a compressor unloader valve?
A compressor unloader valve is a small component, typically measuring around 4-5 inches in length and width, which performs the critical function of releasing trapped air inside the tank. By doing so, it enables the motor to restart. An unloader valve malfunction is one of the more common air compressor issues.
What is an air compressor unloader check valve?
The air compressor unloader check valve keeps the entire tank from draining and has a pipe running to the unloader valve. Above is an unloader valve diagram where the valve is attached to the pressure switch. However, the unloader valve can also be located next to the compressor on larger-scale air compressors.
Where is the unloader valve located on an air compressor?
The unloader valve will most likely be located inside the pressure switch or attached to it on most air compressors. During the operation of the air compressor, the switch turns the compressor off which activates the unloader valve.
How do you unload a screw compressor?
In simpler terms, unloading a screw compressor involves closing the inlet valve to stop the flow of air into the compressor, causing it to halt operation. When Is Unloading a Screw Compressor Used? Unloading a screw compressor is employed when there is no demand for compressed air in the system.
What happens when the air compressor unloader valve is working correctly?
When the the air compressor unloader valve is working correctly, the pressure in the tank has dropped to below the normal cut in pressure level of the pressure switch, the pressure switch trips to allow power to flow through it, and the motor starts.
How does an unloader valve work on a reciprocating compressor?
An unloader valve works on a reciprocating compressor, by releasing compressed air that’s trapped over the piston, between the pump’s cylinder and the tank check valve when the compressor reaches the cut-out pressure and stops.
