RO reverse osmosis purified water equipment ten failures and maintenance methods
1. 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 is not reset after protection
Solution:
1. Water undervoltage, check the insurance, check the wiring
2. The thermal protection element is reset
3. Check waterways to ensure water supply pressure
2. After the equipment is started, the water inlet solenoid valve is not opened
1. Cables are disconnected
2. The internal mechanical of the solenoid valve is faulty
3. The solenoid valve coil is broken
Solution:
1. Check the cable
2. Remove the solenoid valve for repair
3. Repair or replace the coil
3. pump operation, but not up to the rated pressure and flow
1. Pump reversal
2. The filter element of security filter 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 the air from the pump
4. Adjust the pressure after rinse
4. when the system pressure rises, the pump noise is large
1. The 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 leak
5. The solenoid valve is not closed after washing
1. The control component and circuit of the solenoid valve are faulty
2. The solenoid valve is faulty
Solution:
1. Check or replace components and circuits
2. Remove the solenoid valve and repair or replace it
6. under voltage stop
1. Raw water is in short supply
2. The security filter element is blocked
3. Improper pressure adjustment, automatic flushing caused by underpressure
Solution:
1. Check whether the raw water pump and pretreatment system are working
2. Clean and replace the filter element 3. Adjust the system pressure to the best state and maintain the post-filter pressure above 20psi
7. the concentrated water pressure is not up to the rating
1. Pipeline leaks
2. The flushing solenoid valve is not fully closed
3. The recycling system leaks
Solution:
1. Check and repair pipes
2. Check and replace the flushing solenoid valve
3. Check and repair the recovery system
8.the pressure is enough, but the pressure display is not in place
1. The pressure gauge hose is blocked with foreign bodies
2. There is air in the hose
3. The pressure gauge is faulty
Solution:
1. Check and unclog pipes
2. Air out
3. Replace the pressure gauge
9. the water quality is worse
1. Membrane contamination and scaling
2. The seal of the membrane junction fails due to aging
Solution:
1. Chemical cleaning shall be carried out according to technical requirements
2. Replace the O-ring
3. Replace the membrane
10. Decline in output
1. Chemical cleaning shall be carried out according to technical requirements for membrane contamination and scaling
2. Water yield is determined by recalculating the change of water temperature according to the actual water temperature.
