What are the common faults in the use of pure water equipment?

I the high-pressure pump of the pure water treatment equipment does not start and cannot make water 1 Check whether the power is cut off and whether the plug is plugged in 2 Check whether the low-pressure switch is out of order and cannot be connected to the power supply 3 Check whether the water pump and the transformer are short circuited or the wiring of the whole machine is wrong 4 Check whether the high-pressure switch or the water level controller is out of order and cannot be reset 5 Check whether the computer box is faulty (refers to the microcomputer type) 2 The high-pressure pump works normally, but it can't make water 1 The high-pressure pump loses pressure 2 The water inlet solenoid valve is faulty, and it can't make water (no pure water and waste water) (whether it is connected reversely) 3 The pre filter element is blocked (no pure water and waste water or waste water is very small) 4 The check valve is faulty (no waste water and pure water) 5 The automatic flushing solenoid valve fails to close (always in the flushing state) 6 The computer box fails to close (always in the flushing state) 7 The RO membrane is blocked 3 The high-pressure pump does not stop 1 The pressure of the high-pressure pump is insufficient and cannot reach the pressure set by the high pressure 2 The check valve is blocked and does not produce pure water 3 High pressure failure, unable to take off 4 High pressure pump shutdown, but waste water does not stop 1 Solenoid valve failure, unable to effectively cut off the water 2 Computer box failure, unable to close the solenoid valve (refers to the microcomputer type) 3 Check valve pressure relief (small waste water flow) 5 After the water is full, the machine repeatedly takes off 1 Insufficient raw water pressure 2 Pressure relief of check valve 3 Failure of high-pressure switch or liquid level switch 4 Pressure relief of the system 6 Water in the pressure bucket of pure water equipment is full, but pure water cannot flow out 1 Air pressure in the pressure bucket is discharged 2 Activated carbon is blocked after 7 Pure water flow is less than 1 Pre filter element is blocked 2 Pressure of high-pressure pump is insufficient 3 RO membrane is blocked 4 The waste water valve or waste water proportioner is too open 5 The post activated carbon is blocked 6 The pressure of the pressure barrel is insufficient or the internal damage 8 What is the reason for the water leakage near the pipeline interface? 1 Check whether the PE pipe head is cut flat, 2 Check whether the pipe plug is in place, 3 Check whether the nut cap is tightened IX what is the cause of abnormal noise during operation of pure water equipment? 1 Check whether the check valve is out of order or aging 2 Check whether the quality of high-pressure pump has problems 10 What is the reason why the daily water output of pure water equipment fails to meet the requirements? 1 Check whether the calculation is wrong 2 Check whether the water pump pressure is in place (0.6MPa) 3 Check whether the waste water valve or waste water proportioner is too conductive 4 Check whether the water temperature is too low 11 No concentrated water is discharged from the concentrated water pipe The TDS value of the purified water and tap water is the same Possible causes: it may occur after the product has just been installed, the water turbine has been disassembled in a large range, and it has been newly installed It is possible to connect the water pipe between the high-pressure pump and the RO membrane shell directly to the tee of the post activated carbon, so that the tap water from the high-pressure pump can directly enter the water storage barrel Treatment method: change properly 12 The pure water produced has bad taste or peculiar smell 1 Check the filtration effect of RO membrane to see if it is reduced or invalid 2 Check whether the pure water and waste water ends of RO module shell are separated or cracks appear 3 Check whether one end of RO membrane rubber band is of proper size or damaged 4 Check whether the post activated carbon is effective XIII Possible causes for non operation of pure water equipment: 1 Check whether the power is cut off and whether the plug is firmly inserted 2 Check whether the wiring plug of low-voltage switch falls off or fails, so that the power contact cannot return 3 Check whether the connecting wires of each terminal fall off 4 Check whether the water pressure of tap water is too low to cause the low-pressure switch not to work Treatment: 1 Connect the fallen plug 2 Replace the low-voltage switch 3 Install the fallen connecting wire
