What is pure water equipment?
Pure water equipment mainly adopts reverse osmosis membrane technology. Its working principle is to exert a certain pressure on water, so that water molecules and ionic mineral elements pass through the reverse osmosis membrane, while most inorganic salts (including heavy metals), organic substances, bacteria and viruses dissolved in water cannot pass through the reverse osmosis membrane, thus strictly separating the permeated pure water from the impermeable concentrated water; The pore size of reverse osmosis membrane is only 0.000 1 micron, while the diameter of virus is generally 0.02-0.4 micron, and that of common bacteria is 0.4- 1 micron.
Characteristics of pure water equipment
1.？ High water permeability and high desalination rate. Under normal circumstances ≥98%
2.？ It has a high interception and removal effect on organic matter, colloid, particles, bacteria, viruses and heat sources.
3.？ Low energy consumption, high water utilization rate and lower operating cost than other seawater desalination equipment.
4.？ The separation process has no phase change and is reliable and stable.
5.？ The equipment has the advantages of small volume, simple operation, easy maintenance, strong adaptability and long service life.

Fault treatment method of pure water equipment
First, the high-pressure pump of pure water treatment equipment is not started, so it is impossible to make water.
1, check whether there is power failure and whether the plug is plugged in.
2. Check whether the low-voltage switch is faulty and cannot be connected to the power supply.
3. Check whether the water pump and transformer are short-circuited, or the wiring of the whole machine is wrong.
4. Check whether the high voltage switch or water level controller fails and cannot be reset.
5. Check whether the computer box is faulty (microcomputer type)
Second, the high-pressure pump works normally, but it can't produce water.
1, pressure loss of high-pressure pump
2. The water inlet solenoid valve is out of order, and water cannot enter (there is no pure water and waste water) (whether it is reversed).
3. The front filter element is blocked (there is no pure water wastewater or little wastewater)
4. Check valve failure (waste water without pure water)
5. The automatic flushing solenoid valve fails and cannot be effectively closed (it has been in flushing state).
6. If there is something wrong with the computer box, the recoil solenoid valve cannot be closed (it is always in the flushing state).
7, reverse osmosis membrane blockage
Third, the high-pressure pump does not stop.
1, the high-pressure pump pressure is insufficient, and the high-pressure set pressure cannot be reached.
2. The check valve is blocked and pure water cannot be produced.
3. High voltage failure, unable to take off.
Fourth, the high-pressure pump stopped, but the wastewater continued.
1, solenoid valve failure, unable to effectively cut off water.
2. There is something wrong with the computer box, and the solenoid valve (microcomputer type) can't be turned off.
3, check valve pressure relief (small waste water flow)
Five, after the water is full, the machine beats repeatedly.
1, raw water pressure is insufficient.
2, check valve pressure relief
3, high voltage switch or liquid level switch failure
4. There is pressure release in the system.
The pressure barrel of pure water equipment is full of water, but pure water cannot flow out.
1, the pressure of the pressure barrel is released.
2. The rear activated carbon is blocked.
Seven, pure water flow is insufficient.
1, the front filter element is blocked
2. Insufficient pressure of high-pressure pump
3. The reverse osmosis membrane is blocked
4. The waste water valve or waste water proportional device is too conductive.
5. The rear activated carbon is blocked
6. Insufficient pressure or internal damage of the pressure barrel.
8. What is the reason for the water leakage near the pipe joint?
1, check whether the PE pipe head is cut flat.
2. Check whether the plug is in place.
3. Check whether the screws are tightened.
9. What is the reason for the abnormal sound during the operation of pure water equipment?
1, check the check valve for failure or aging.
2. Check whether there is any problem with the quality of high-pressure pump.
X. What is the reason why the sunrise water quantity of pure water equipment can't meet the requirements?
1, check whether the calculation is wrong.
2, check whether the pump pressure is in place (0.6Mpa)
3. Check whether the waste water valve or waste water proportional mixer is too conductive.
4. Check whether the water temperature is too low.
Xi。 There is no concentrated water discharged from the concentrated water pipe, and the TDS value of purified water is the same as that of tap water.
Possible reasons: it may appear after the product has just been installed, and the water machine has been disassembled and reinstalled in a large scale. The water pipe between the high-pressure pump and the RO membrane shell is directly connected to the tee joint of the post-positioned activated carbon, so it may be wrong to let the tap water from the high-pressure pump directly enter the water storage bucket.
Solution: Connect correctly.
12. The prepared pure water has bad taste or peculiar smell.
1. Check whether the filtration effect of RO membrane is reduced or invalid.
2. Check whether the pure water end and waste water end of RO membrane shell are separated or cracked.
3. Check whether one end of the RO membrane rubber belt is of proper size or damaged.
4. Check whether the post activated carbon is effective.
Thirteen, pure water equipment doesn't work
Possible reasons:
1, check whether there is power failure and whether the plug is firmly inserted.
2. Check whether the wiring plug of the low-voltage switch falls off or fails, so that the power contact cannot return.
3. Check whether the connecting wire of each terminal falls off.
4, check whether the tap water pressure is too low, so as not to cause low voltage switch doesn't work.
Treatment method:
1. Connect the dropped plug.
2. Replace the low-voltage switch
3. Install the disconnected cable
