Pure water machine fault mostly caused by electromagnetic valve

Pure water machine fault of electromagnetic valve causes the chemical instruments of network times a solenoid valve manufacturer. High pressure pump is not started, cannot make water check whether the power outage, the plug is in check whether low voltage switch failure, can't check whether the pump and transformer short circuit power supply is connected, or the whole machine line connection is wrong, check whether the high voltage switch or water level controller is failure can't reset check box if there is a computer fault ( The microcomputer type) 2. High-pressure pump to work properly, but cannot make water high-pressure pump inlet pressure loss solenoid valve malfunction cannot fill ( Pure water waste water are not) ( Whether meet the) Pre filter clogging ( Pure water wastewater are no or wastewater is small) Non-return valve failure ( Is wastewater not pure water) Automatic flush solenoid valve failure, cannot effectively closed ( Has been in flushing state) Defective computer box cannot be closed recoil solenoid valve ( Has been in flushing state) RO membrane block 3. High-pressure pump non-stop high-pressure pump pressure is insufficient, cannot achieve high pressure setting pressure check valve plug, not out of the water high pressure failure, can't jump four. High-pressure pump stop, but waste water electromagnetic valve failure, cannot effectively computer box is faulty, no water electromagnetic valve cannot be shut down, The microcomputer type) Non-return valve pressure ( Wastewater discharge small) Five. Insufficient water, after the expiration of the raw water pressure machine repeatedly takeoff non-return valve pressure relief system of high voltage switch or liquid level switch failure phenomenon of pressure relief six. Pressure bucket of water, but water cannot flow pressure barrel drain off the rear air pressure activated carbon block 7. Insufficient water flow front filter clogging high-pressure pump pressure proportioner RO membrane valve jams waste water or wastewater is too insufficient pressure conduction rear active carbon block pressure barrels or internal damage to eight. Pipeline leak near interface is what reason? Check whether the PE tube head is cut flat, check whether the pipe plug is in place and check the screw are on tight.
