About Failure and repair of diaphragm
1. The spring is damaged. The spring on the pulse valve spool is easily damaged. The appearance is that the pulse valve is deflated to the blow port for a long time. The treatment method is to replace the spring.
2. The rubber pad is damaged. After the use time is long, the rubber pad on the pulse valve spool is easily damaged. The appearance is that the pulse valve is deflated to the blowing port for a long time. The treatment method is to replace the rubber pad.
3, the valve core dirt, because the intake air is not clean, causing the fouling of the valve core, resulting in the appearance of long-term intake of the nozzle or the pulse valve does not work after the power, the treatment method is to clean the valve core.
4, the diaphragm is damaged, after long-term work, the diaphragm is easy to fatigue, oxidation, etc., resulting in the appearance of long-term deflation of the pressure relief port, the pulse valve does not work, the treatment is to replace the diaphragm.
5. The orifice is blocked or damaged. The intake air is not clean and the throttle hole is blocked. The appearance is that the pulse valve is deflated to the nozzle for a long time. The treatment method is to clean the orifice; the orifice is damaged or missing, and the orifice is made. Loss of interception, resulting in abnormal pressure relief, the appearance of the pulse valve after the power is activated, the pressure relief port deflation, but the pulse valve is not sprayed, the treatment is a replacement orifice.
