Screw air compressor inlet valve appears closed reasons and solutions
There are two control methods: one is a switch, when the pressure of the gas tank reaches the high limit set value, close the air inlet, when the pressure drops to the low limit set value, re-open the air inlet. The other is that when the gas tank reaches a certain pressure, the rotating disc slightly closes the air inlet under the control of the proportional valve. When the pressure of the gas tank further increases, the air inlet is further reduced. When the pressure of the gas tank is slightly reduced, the air inlet will be increased to stabilize the pressure in a certain range. When the pressure does not reach the regulating pressure, the intake valve disc is fully opened and the intake port is fully opened.

In the case of operation, screw air compressor intake valve appears closed reasons and solutions:
1. Excessive water in the control pipeline, maintain the control pipeline every day.
2, the intake valve work error; check the cylinder, valve sleeve and other components, if necessary, replace.
3, air intake valve stuck; check the intake valve, valve sleeve, or shaft, if necessary, replace.
4. The intake valve spring is broken; replace the spring.
5, solenoid valve failure; repair or replace as needed, check the wiring before replacement.
6. The reciprocating valve is damaged; repair or replace.
7. The solenoid valve wire connector is loose; check and tighten the wire terminal.
These will cause the screw air compressor intake valve failure, in the production operation should be handled with caution. The intake valve is generally a normally closed valve to prevent a large amount of gas from entering the machine head when starting and increase the starting current of the motor.
