RO reverse osmosis purified water equipment ten failures and maintenance methods
First, the switch is on, but the device does not start:
1. Electrical line failure, such as bad insurance, wire fall off
2. The thermal protection element does not reset after protection
The solution:
1. Water undervoltage, check the insurance, check the wiring
2. Reset the thermal protection element
3. Check waterways to ensure water supply pressure
Second, after the equipment is started, the water inlet solenoid valve is not opened:
1. Cables are disconnected
2. The internal mechanical fault of the solenoid valve occurs
3. The solenoid valve coil is faulty
The solution:
1. Check the cable
2. Remove the solenoid valve for repair
3. Repair or replace the coil
Third, the pump operation, but not up to the rated pressure and flow:
1. Pump reversal
2. The security filter element is dirty
3. There is air in the pump
4. Flush the solenoid valve to open
Solution:
1. Reconnect cables
2. Clean or replace the filter element
3. Remove air from the pump
4. Adjust the pressure after rinse
Fourth, when the system pressure rises, the pump noise is large
1. Raw water flow is not enough
2. Raw water flow is unstable
Solution:
1. Check the original water pump and pipes
2. Check whether the original water pump and pipes are leaking
5. The solenoid valve is not closed after washing
1. The control components and circuits of the solenoid valve are faulty
2. The solenoid valve is faulty
The solution:
1. Check or replace components and circuits
2. Remove the solenoid valve and repair or replace it
Sixth, under voltage stop
1. Insufficient supply of raw water
2. The security filter element is blocked
3. Improper pressure adjustment, automatic flushing caused by underpressure
The solution:
1. Check whether the original water pump and pretreatment system are working
2. Clean and replace the filter element 3. Adjust the system pressure to the best state, so that the filter pressure is maintained at more than 20psi
Seven, the concentrated water pressure does not reach the rated value
1. Pipeline leakage
2. The flushing solenoid valve is not fully closed
3. The recycling system is leaked
The solution:
1. Check and repair pipes
2. Check and replace the flushing solenoid valve
3. Check and repair the recycling system
Eight, the pressure is enough, but the pressure display is not in place
1. The pressure gauge hose is blocked with foreign matter
2. There is air in hose
3. The pressure gauge is faulty
The solution:
1. Check and dredge pipes
2. Remove air
3. Replace the pressure gauge
Nine, the water quality deteriorates
1. Membrane contamination and scaling
2. The seal of the membrane junction fails due to aging
The solution:
1. Chemical cleaning according to technical requirements
2. Replace the O-ring
3. Replace the membrane
Ten. Decline in production
1. Membrane contamination, scaling, chemical cleaning according to technical requirements
2. Water temperature change is determined by recalculating the actual water temperature.
