Small water purification equipment may appear failures and solutions
First, the high pressure pump of small purified water equipment does not start, and can not make water
1. Check whether there is a power failure and whether the plug is plugged in.
2. Check whether the low-voltage switch is out of order and cannot be connected to the power supply.
3. check whether the water pump and transformer short circuit, or the whole machine line connection is wrong.
4. Check whether the high pressure switch or water level controller is out of order and cannot be reset.
5. check whether there is a fault in the computer box (referring to the microcomputer).
Two, the high pressure pump of small pure water equipment works normally, but can not make water
1. high pressure pump pressure loss.
2. The inlet solenoid valve is faulty and can not fill the water (pure water and wastewater are not)(whether it is reversed).
3. The pre-filter element is blocked (no pure water or waste water is small).
4. check valve failure (there is no pure water waste water).
5. automatic flushing solenoid valve failure, can not be effectively closed (has been in the flushing state).
6. the computer box has a fault can not close the recoil solenoid valve (has been in the state of washing).
7. RO membrane is blocked.
Three, small pure water equipment high pressure pump do not stop
1. the high pressure pump pressure is insufficient, can not reach the high pressure set pressure.
2. the check valve is blocked, not out of pure water.
3. high pressure failure, unable to jump.
Four, the high pressure pump of small pure water equipment stops, but the wastewater does not stop
1. solenoid valve failure, can not effectively cut off water.
2. the computer box has a fault, can not close the solenoid valve (refers to microcomputer type).
3. check valve pressure relief (small wastewater flow).
Five, small pure water purification equipment is full of water, the machine repeatedly jump
1. Insufficient raw water pressure.
2. check valve pressure relief.
3. high pressure switch or level switch failure.
4. the system has pressure relief phenomenon.
