The reasons and solutions for the inability to open the intake valve of a screw air compressor. The intake valve of a screw air compressor is a component that controls the air pressure inside the air storage tank. Commonly used intake valves include a rotating disc structure and a reciprocating valve plate mechanism, which use a disc or valve plate to open or close the intake port and control the airflow entering the machine head< Br/>


There are two control modes: one is a switch, which closes the air inlet when the pressure in the gas tank reaches the upper limit setting value, and reopens the air inlet when the pressure drops to the lower limit setting value. The other is that when the gas tank reaches a certain pressure, the rotating disc is slightly close to the air inlet under the control of the proportional valve. As the pressure of the air tank further increases, the air inlet further decreases as the pressure of the air tank increases. A slight decrease will increase the air intake and stabilize the pressure within a certain range. If the pressure does not reach the allowable pressure, the intake valve disc is fully open and the intake port is fully open< Br/>


What is the reason for closing the intake valve of the screw air compressor while driving? What is the solution? Let's have a brief talk< Br/>


1. Maintain the control pipeline daily by controlling too much water in the pipeline.

2. Check the cylinder, valve sleeve, and other components, and replace them if necessary, as the intake valve will not function properly< Br/>


3. The intake valve is blocked; Check the intake valve, valve sleeve or shaft, and replace if necessary< Br/>


4. The intake valve spring is damaged; Replace the spring



5. Electromagnetic valve failure; Repair or replace if necessary, and check the wiring before replacement< Br/>


6. The shuttle valve is damaged; Repair or replace< Br/>


7. If the solenoid valve wire connector is loose, check and tighten the wire terminals< Br/>


These may cause the inlet valve of the screw air compressor to malfunction and should be handled with caution during the production process. The intake valve is a normally closed valve, which can prevent a large amount of gas from entering the machine head during the starting process and increase the motor starting current. The intake valve of the screw air compressor has an intake bypass valve, which prevents the machine from starting and discharging. In addition, the formation of high vacuum on the machine head affects the atomization of lubricants< Br/>
