Pulse valve failure and repair

1. The spring is damaged. The spring on the pulse valve core is easily damaged, which causes the pulse valve to deflate to the blow port for a long time. The solution is to replace the spring.

2. The rubber gasket is damaged. After being used for a long time, the rubber gasket on the pulse valve core is easily damaged, which causes the pulse valve to deflate to the blow port for a long time. The solution is to replace the rubber gasket.

3. Dirt on the valve core. Due to unclean air intake, dirt accumulates at the valve core. The result is that the injection port has long-term air intake or the pulse valve does not operate after power is supplied. The solution is to clean the valve core.

4. The diaphragm is damaged. After long-term operation, the diaphragm is prone to fatigue, oxidation, etc. The resulting symptoms are that the pressure relief port deflates for a long time and the pulse valve does not work. The solution is to replace the diaphragm.

5. The throttle hole is clogged or damaged. Unclean air intake can easily cause the throttle hole to become clogged. The symptom is that the pulse valve vents air to the injection port for a long time. The solution is to clean the throttle hole. If the throttle hole is damaged or missing, the throttle hole will be blocked. The interception function is lost, resulting in abnormal pressure relief. The symptom is that the pulse valve moves after power is turned on, and the pressure relief port deflates, but the pulse valve does not blow. The solution is to replace the orifice.
