Excavator machinery parts 152-8346 Solenoid valve for Carter

    What is the performance of the solenoid valve broken, in fact, very simple, no professional detection tools can also judge the solenoid valve is broken, if you use the solenoid valve can not work properly and do not know whether it is good or bad, generally can take three simple steps, one listen, two look, three tests, the above three steps can judge most of the problems, The following by our Taiming technical staff to share with you the electromagnetic valve is broken what is the simple judgment method.

First: listen to the performance of the voice;

1, the action speed of the solenoid valve is fast, under normal circumstances, the power will hear a sound of "da", crisp, if the coil is burned, there will be no sound;

2, there is another situation is the power after the continuous "da" "da" "da" sound, this is generally insufficient suction, consider whether the voltage is not enough or the valve cavity impurities lead to the spire stuck;

3. There will also be sound after the AC solenoid valve is powered on, but this continuous and stable current sound is normal;

4, if the solenoid valve has action, at this time should be able to hear the flow of the pipeline medium or the outlet gas liquid outflow:

Second: Look at the external performance:

1, see whether the coil bag, split,

2, see whether the wiring is damaged;

3, the valve body has no cracking, especially some plastic or iron valve bodies, easy to age at low temperature or high temperature, this problem may occur;

Third: test internal performance;

1, if the coil is good, there will be a magnetic field in the coil hole, use a screwdriver to try to know:

2, touch the temperature of the coil, after the general solenoid valve is energized, it is hot to touch, if it is cold, you can judge the connection break or the wire is burned.

3, if you can hear the sound of water or air flow at the outlet of the pipeline after closing, what is the performance of the broken solenoid valve - this is an obvious one, that is, the valve is not tightly closed, the sealing position is wrong, the seal is damaged or aging - replace the seal, the valve has debris - remove debris.
