How to repair the electromagnetic pulse valve after encountering a fault

Pulse valve refers to a diaphragm valve that is controlled by a pilot valve such as electromagnetic or pneumatic, and can open and close a high-pressure gas source to generate pulses in an instant. Pulse valve is the main component of the bag filter, blowing to more than 1 million times.

How to repair the failure of the pulse valve? 

1, spring damage, the spring on the pulse valve spool is easy to damage, resulting in the appearance of the pulse valve long-term venting to the blowhole, the treatment is to replace the spring.

2, gaskets damage, after a long time of use, the pulse valve spool gaskets easily damaged, resulting in the appearance of the pulse valve long-term venting to the blowhole, the treatment is to replace the gaskets.

3, spool dirt, due to the air inlet is not clean, resulting in the accumulation of dirt at the spool, resulting in the appearance of a long-term blowing mouth into the air or power after the pulse valve does not act, the treatment is to clean the spool.

4, the diaphragm is damaged, after long-term work, the diaphragm is easy to fatigue, oxidation, etc., resulting in the appearance of the pressure relief port for a long time to bleed air, the pulse valve does not work, the treatment is to replace the diaphragm.

5, throttle hole clogging or damage, air inlet is not clean easily lead to throttle hole clogging, the appearance of the pulse valve to the blowing mouth for a long time to bleed air, the treatment is to clean the throttle hole;

Throttle hole is damaged or missing, so that the throttle hole loses the function of retention, resulting in pressure relief is not normal, the appearance of power after the pulse valve has action, the pressure relief port bleed, but the pulse valve does not blow, the treatment is a replacement of the throttle hole.
