ZEGA screw air compressor intake valve failure inspection and maintenance, will you?

　　ZEGA screw air compressor intake valve belongs to normally open type intake valve, when the screw air compressor is not loaded, the solenoid valve is open, and the solenoid valve is closed after the compressor is loaded.

When the solenoid valve is opened, there will be a gas all the way to close the intake valve, but it cannot be completely closed, and the intake space must be reserved to maintain the minimum pressure required for compressor lubrication. This pressure is generally 1.5 bar; after the solenoid valve is closed, the compressor will enter normal operation until the set working pressure is reached, depending on the user. <a href="http://www.5293333.com/">span style< style="color:#eeeeee;"> http://www.5293333.com/

　　The intake valve has two pipes, one way empty; Drain the residual gas in the valve all the way to ensure the normal loading of the compressor. When unloading, the current is too large, indicating that the tank pressure is high, the opening of the intake valve is large, please adjust the venting screw to ensure that the tank pressure is not too high.

　　 after the Chigo screw air compressor is stopped, the tank pressure can generally be completely emptied in about 60 seconds, that is, the pressure is 0, and your tank pressure is still 6bar, indicating that there is a problem with the intake valve venting pipeline: it may be that the diameter of the pipeline is too thin; The combination valve orifice is too small or whether it is blocked by debris.

　　After unloading, the pressure will rise back and forth slightly, but this is only needed for balance, and it is short. It will not rise to high-pressure shutdown, high-pressure shutdown should be a problem with the solenoid valve of the air compressor, please check whether it is intact and whether it can work normally. No matter what kind of intake valve, the tank pressure should be maintained between 1.0~2.0BAR when unloading. Too high is a big waste of energy for screw air compressors.

Reasons and solutions for the intake valve of Chigo screw compressor cannot be opened:

　　The intake valve of Chigo screw air compressor is a component that controls the air pressure in the air tank, and the commonly used intake valve has a rotating disc structure and reciprocating valve plate mechanism, which uses the disc or valve plate to open or close the air inlet to control the airflow into the machine head.

　　There are two control methods:

　　One is a switch, when the pressure of the air receiver reaches the high limit set value, close the air intake, and when the pressure drops to the low limit set value, reopen the air intake.

　　The other is that when the air 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 air tank further increases, the air inlet is further reduced, and when the pressure of the air tank is slightly reduced, the air inlet will be increased, so that the pressure is stable in a certain range. When the pressure does not reach the volumetric pressure, the inlet valve disc is fully open and the air inlet is fully open.

In the case of operation, < a href="http://www.hnzega.com"> what are the reasons why the intake valve of the Chigo screw compressor is closed. What are the solutions? Let's take a brief look!

　　1. Control the excessive water in the pipeline, and maintain the control pipeline every day.

　　2. The inlet valve works incorrectly; Check cylinders, valve sleeves and other parts, and replace them if necessary.

　　3. The air intake valve is stuck; Check the intake valve, sleeve, or shaft and replace it if necessary.

　　4. The intake valve spring is broken; Replace the spring< br/>
　　5. Solenoid valve failure; Repair or replace as needed, and check the wiring before replacement.

　　6. The reciprocating valve is damaged; Repair or replacement.

　　7. The solenoid valve wire joint is loose; Check and tighten the wire terminals.

　　These will cause Chigo screw compressor intake valve failure, should be handled carefully during production operation.
