The high-pressure pump of pure water equipment plays a very important role in the entire operation process, but it is also a frequently problematic component, and some are difficult to handle, such as how to reset it

Reset method for high-pressure pump of pure water equipment: 1. Check if there is a common fault in the low-pressure switch, and do not turn on the switch power; 2. Check if there is a short circuit fault and transformer in the pump, and if there are all or incorrect route connections; 3. Check if the high-voltage circuit breaker or liquid level controller has failed to reset; 4. Check if there are common faults in the electronic computer box (referring to the type of microcomputer).

The high-pressure pump has stopped operating and the sewage has not stopped: 1. Common faults in the relay make it impossible to disconnect the water reasonably; 2. Box defect: Electronic computers and relays cannot be turned off (refer to microcomputer models); 3. Check valve pressure relief (low total sewage flow).

The high-pressure pump is working normally, but cannot produce water: 1. The high-pressure pump is overpressure; 2. The electromagnetic water valve has common faults and cannot leak water (there is no pure water or sewage) (is it connected incorrectly); 3. External filter clogging (with no or little pure water or sewage); 4. Check valve failure (with sewage but no purified water); 5. The fully automatic cleaning relay is malfunctioning and cannot be turned off properly (it has been in cleaning mode); 6. If there is a common malfunction on the computer box, the recoil relay cannot be turned off (it has been in cleaning condition); 7. RO membrane blockage.

Shutdown time of high-pressure pump: 1. The working pressure of the high-pressure pump cannot reach the high pressure set working pressure; 2. The reverse shut-off valve is blocked and there is no purified water; 3. High voltage common malfunction, unable to take off and land.
