RO pure water machine (or RO reverse osmosis pure water machine /RO water purification machine) is the use of reverse osmosis technology principle for water purification machine. Under a certain pressure, water molecules (H2O) can pass through the RO membrane, while the inorganic salts, heavy metal ions, organic matter, colloid, bacteria, viruses and other impurities in the source water can not pass through the RO membrane, so that a part of the water through the RO membrane is separated, and the water not through the solute increases to form concentrated water.
High pressure pump does not start, 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 faulty and cannot be connected to the power supply
(3) Check whether the water pump and transformer are short-circuited or the circuit is incorrectly connected
(4) Check whether the high pressure switch or water level controller (refers to the vertical ice heat machine) fails to reset
⑤ Check whether the computer case is faulty (referring to the microcomputer type)
Folding ⑵ high pressure pump works normally, but can not make water
(1) High pressure pump loss of pressure
② Water inlet solenoid valve can not open can not water (pure water thick water are not)
(3) The front filter element is blocked (no pure water or concentrated water is very small)
④ Check valve failure (waste water without pure water)
⑤ Automatic flushing solenoid valve failure, can not be effectively closed (has been in the state of flushing)
⑥ Computer box failure can not close the recoil solenoid valve (has been in the state of flushing)
All landowners RO membrane congestion
Fold the high pressure pump does not stop
The high pressure pump pressure is insufficient, can not reach the high pressure setting pressure
(2) The check valve is blocked, and no pure water is produced
③ High voltage switch failure, unable to jump
Fold the high pressure pump shut down, but the wastewater does not stop
① Water inlet solenoid valve failure, can not effectively cut off water
② The computer box is faulty, can not close the inlet solenoid valve (refers to the microcomputer type)
③ Pressure relief of check valve (concentrated water flow is small)
Fold (5) after the water is full, the machine jumps repeatedly
(1) Pressure relief of check valve
(2) High pressure switch or liquid level switch (referring to vertical ice heat machine) failure
(3) Pure water pipeline system has pressure relief phenomenon
Folding ⑹ pressure bucket full of water, but pure water can not flow out
(1) Relieve the pressure of the pressure bucket, inflate until the water in the bucket is just discharged, about 0.3mpa, and fill the pressure to 0.04-0.08mpa according to the barometer.
(2) the rear activated carbon is blocked
◎ Insufficient pure water flow
(1) the front filter element is blocked
(2) the high pressure pump pressure is insufficient
③ RO membrane blockage
(4) Flush the solenoid valve, it cannot be closed
⑤ Post reactive carbon plug
⑥ Pressure drum pressure is insufficient or tank leakage
What is the cause of water leakage near the pipe interface?
◆ Check whether the PE pipe head is cut flat,
◆ Check whether the plug is in place.
◆ Check whether the screw is tightened.
Folding water machine operation process has the abnormal noise is the reason?
Check whether the check valve is out of order or aging
◆ Check whether the high pressure pump quality problems
◆ The original water pressure is too low, the pump body is filled with air
Folding of the daily water volume of the water machine does not meet the requirements is the reason?
◆ Check whether the calculation is wrong
◆ Check whether the pump pressure is in place (0.6mpa)
◆ Check whether the flushing solenoid valve is closed loosely
◆ Check whether the water temperature is too low
Folding (vacuuming) pipes do not drain concentrated water
No concentrated water is discharged from the concentrated water pipe. The TDS value of purified water is the same as that of tap water
Possible causes:
◆ May appear in the product just installed, a large range of disassembly of the water machine, after the new installation. The water pipe between the high pressure pump and the RO membrane shell may be wrongly connected directly to the three-way place of the activated carbon after the high pressure pump, so that the tap water directly enters the storage bucket.
Treatment method:
◆ Correct replacement
Folding (11) machine does not work why?
Possible causes:
◆ Check whether power failure, plug insertion is secure.
◆ Check whether the low-voltage switch wiring plug falls off or fails to cause the power contact can not return to position.
◆ Check whether the connecting wire of each terminal falls off.
◆ Check whether the water pressure is too low to cause the low pressure switch does not work.
Treatment method:
◆ Connect the missing plug
◆ Replace the low-voltage switch
◆ Install the loose cable
When folded, pure water will have bad taste or bad smell. Why?
◆ Check whether the pure water and concentrated water end of RO membrane shell is cut off or crack.
◆ Check whether one end of RO film rubber band is suitable or damaged.
◆ Check whether the post activated carbon action is effective.
