The pulse valve can be repaired when it fails. Common faults of the pulse valve include power supply problems, circuit connection problems, valve core dirt, diaphragm damage, spring or rubber pad damage, etc. These problems can be solved by corresponding maintenance measures.
Common faults and solutions
Power supply problem: Check whether the power switch is turned on, whether the power cord is plugged in tightly, and whether the power supply is normal. If there is a problem with the power supply, the power supply should be repaired or replaced in time.
Circuit connection problem: Check the connection line between the pulse valve and the controller to ensure that there is no poor contact, short circuit or open circuit. If a line problem is found, the damaged line needs to be reconnected or replaced.
Valve core dirt: If the pulse valve has carbon deposits after long-term use, the valve core should be cleaned regularly with a cleaning agent to remove the carbon deposits. If cleaning is ineffective, the valve core may need to be replaced.
Damage to the diaphragm: After long-term work, the diaphragm is prone to fatigue and oxidation, etc., resulting in long-term deflation of the pressure relief port. The solution is to replace the diaphragm.
Spring or rubber pad damage: If the spring or rubber pad on the pulse valve is damaged, it will also cause the pulse valve to not work. The solution is to replace the spring or rubber pad.
Throttle hole blockage: Unclean intake air can easily lead to throttle hole blockage. The solution is to clean the throttle hole; if the throttle hole is damaged or missing, the throttle hole needs to be replaced.
Repair steps and required tools
Check the power supply and circuit connection: Use a multimeter to detect the power supply voltage and circuit connection to ensure that the power supply is normal and the circuit connection is good.
Clean or replace the valve core: Use a cleaning agent to clean the valve core to remove carbon deposits; if cleaning is ineffective, the valve core needs to be replaced.
Replace the diaphragm and spring: Check the status of the diaphragm and spring. If damaged, replace a new diaphragm and spring.
Check and clean the throttle hole: Use a cleaning agent to clean the throttle hole to ensure that it is unobstructed.
Reinstall and debug: Make sure the valve is installed correctly, the sealing surface is flat, the connection is tight, and debug to ensure the normal operation of the valve.
