1. The spring is damaged, and the spring on the pulse valve core is easily damaged, resulting in the appearance that the pulse valve is blowing in the nozzle for a long time, and the treatment is to replace the spring.



2. When the rubber pad is damaged, after long use, the rubber pad on the pulse valve core can be easily damaged, resulting in the appearance that the pulse valve has long been blowing into the nozzle, and the treatment method is to replace the rubber pad.


Dirt 3, valve core, due to the air inlet is not clean, cause the valve core of dirt to accumulate knot, causing the appearance of injection port is long-term intake or after electric pulse valve not action, processing way is to clean the valve core.


4. The diaphragm is damaged. After a long period of work, the diaphragm is easy to be tired and oxidized. The appearance of the diaphragm is the long-term release of the pressure relief valve. The pulse valve does not work.


5. The throttle hole is blocked or damaged, and the air intake is not clean and easy to cause the blockage of throttling holes. The appearance is that the pulse valve has long been injected into the nozzle, and the treatment mode is to clean the throttle orifice. Orifice damaged or missing, the orifice loss of intercept, result in normal pressure and the appearance is some action after electric pulse valve, pressure relief vent mouth, but not for injection pulse valve, handling is a change of orifice.
