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.
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 in the storage tank. Common intake valves include rotary disc structure and reciprocating valve plate mechanism. The disc or valve plate is used to open or close the intake port, thereby controlling the airflow entering the compressor head.
There are two control modes: one is a switch. When the pressure in the gas tank reaches the upper limit set value, the air inlet is closed. When the pressure drops to the lower limit set value, the air inlet is reopened. The other mode is that when the gas tank reaches a certain pressure, the rotating disc, under the control of the proportional valve, slightly approaches the air inlet. As the pressure in the gas tank increases further, the air inlet further decreases with the increase in the pressure of the gas tank. A slight decrease will open the air inlet and stabilize the pressure within a certain range. If the pressure does not reach the allowable pressure, the air inlet valve disc is fully opened and the air inlet is fully open.
What is the reason for closing the intake valve of the screw air compressor during operation? What is the solution? Let's have a brief discussion about it!
Maintain the control pipeline by controlling the water flow within it on a daily basis.
2. Inspect the cylinders, valve sleeves and other components, and replace them if necessary, as the intake valve will not function properly.
3. Air intake valve blockage; Inspect the air intake valve, valve sleeve or shaft. Replace if necessary.
4. Intake valve spring damaged; replace the spring
5. Electromagnetic valve failure; if necessary, perform maintenance or replacement. Before replacement, check the wiring.
6. Throttle valve damaged; repair or replacement is required.
7. The wire connector of the electromagnetic valve is loose. Check and tighten the wire terminals.
These may cause faults in the intake valve of the screw air compressor, and should be handled carefully during production. The intake valve is a normally closed valve, which prevents a large amount of gas from entering the head during startup and increases the starting current of the motor. The intake valve of the screw air compressor has an intake bypass valve, which prevents the machine from starting and discharging. Moreover, a high vacuum is formed at the head, which affects the atomization of the lubricant.
