No matter when, people are inseparable from water. There is a saying that water is the source of life. People will not starve to death if they don’t eat for a day, but they will die of thirst if they don’t drink water for a day. So water How important it is for people. The water resources we generally use or drink must be filtered by a pure water machine before they can be consumed directly, because a pure water machine can provide people with clean water compared to a water purifier. The following is Xiaotu’s introduction to commercial pure water machines. If the pure water machines malfunction, how to repair them.
Commercial pure water machine
Commercial pure water machine is a kind of water purification equipment that uses multi-stage filter elements to purify water. It mostly uses filtration, adsorption, Physical methods such as reverse osmosis. According to the water purification accuracy of commercial pure water machines, they can be divided into two categories: domestic drinking pure water machines, also called household pure water machines, and laboratory pure water machines that can meet laboratory pure water quality requirements.
Introduction to the faults and maintenance of commercial pure water machines:
1. The high-pressure pump does not start and water cannot be produced? Check whether there is a power outage and whether the plug is plugged in
Solution: Check whether the low-voltage switch is malfunctioning and cannot be connected to the power supply
Check whether the water pump and transformer are short-circuited, or whether the wiring of the whole machine is incorrectly connected? Check whether the high-voltage switch or water level controller is malfunctioning and cannot be reset? Check the computer Is the box faulty (referring to the microcomputer type)
2. The high-pressure pump works normally, but cannot produce water? The high-pressure pump loses pressure
Treatment method: The water inlet solenoid valve is faulty and cannot flow. Water (no pure water or waste water) (is the connection reversed)? The pre-filter is clogged (no pure water or waste water or the waste water is very small)? The check valve is malfunctioning (there is waste water but no pure water). The automatic flushing solenoid valve is malfunctioning and cannot be effectively closed. (Always in the flushing state)? The computer box is faulty and cannot close the recoil solenoid valve (always in the flushing state)? The RO membrane is clogged
3.? The high-pressure pump does not stop
How to deal with it : The high-pressure pump has insufficient pressure and cannot reach the high-pressure setting pressure? The check valve is clogged and no pure water comes out? The high-pressure pump fails and cannot start up
4.? The high-pressure pump stops, but the waste water does not stop? The solenoid valve Failure, cannot effectively cut off the water
Treatment method: The computer box is faulty, the solenoid valve cannot be closed (referring to the microcomputer type), the check valve must be relieved (the wastewater flow is small)
5. Water After the machine is full, the machine jumps repeatedly? Insufficient raw water pressure? Check valve pressure relief
Treatment method: The high-pressure switch or liquid level switch fails? There is pressure relief in the system
6. Pressure barrel The water is full, but the pure water cannot flow out
Treatment method: The pressure barrel is released and the rear activated carbon is clogged
7. Insufficient pure water flow? The pre-filter is clogged and the high-pressure pump has insufficient pressure. ?RO membrane is clogged
Treatment method: The wastewater valve or wastewater proportioner is too conductive? The rear activated carbon is clogged, the pressure barrel has insufficient pressure or is internally damaged
8. Pipe interface What is the cause of water leakage nearby?
Treatment method: Check whether the PE pipe head is cut flat, check whether the pipe plug is plugged in place, and check whether the screw cap is tightened.
9. What is the reason for the abnormal noise during the operation of the water machine?
Treatment method: Check whether the check valve is malfunctioning or aging? Check whether there is a problem with the quality of the high-pressure pump
10. What is the reason why the daily water production of the water machine does not meet the requirements?
Treatment method: Check whether the calculation is wrong, check whether the water pump pressure is in place (0.6Mpa)? Check the wastewater valve or wastewater ratio Is the water heater too conductive? Check whether the water temperature is too low
11. No concentrated water is discharged from the concentrated water pipe, and the TDS value of the purified water is the same as that of tap water. Why?
Possible reasons : It may appear after the product has just been installed, the water machine has been disassembled in a large area, and it has been reinstalled. It may be wrong to connect the water pipe between the high-pressure pump and the RO membrane shell directly to the post-activated carbon tee, so that the tap water from the high-pressure pump directly enters the water storage barrel.
Treatment method: Correctly change the connection
12. What is the reason why the machine does not work? Possible reasons:
Treatment method: Check whether there is a power outage and whether the plug is inserted Is it reliable?
Check whether the low-voltage switch wiring plug has fallen off or failed, causing the power contacts to fail to return. ?Check whether the connecting wires of each terminal block are disconnected.
Check whether the tap water pressure is too low, causing the low-pressure switch to not work.
?Connect the fallen plug? Replace the low-voltage switch and install the fallen connecting wire
13. The produced pure water tastes bad or has a peculiar smell. Why?
How to deal with it: Check the filtration effect of the RO membrane to see if it is reduced or failed, and check whether the pure water and wastewater ends of the RO membrane shell are separated or cracked. ?Check whether one end of the RO membrane rubber ring is of appropriate size or damaged. ?Check whether the post-activated carbon function is effective.
Okay, the above is Xiaotu’s brief introduction to the malfunctions and solutions of commercial pure water machines. I hope it will be helpful to everyone when using commercial pure water machines. So when there is a problem with our commercial pure water machine, everyone will deal with it according to the maintenance methods shared by Xiaotu. At the same time, we should pay attention to the method to solve the problem and not blindly deal with it! If we still have problems with our commercial water purifier after repairs, it may be a hardware failure. Then we can ask professionals to repair or update a new commercial water purifier!
