金彩汇Ten faults and maintenance methods of RO reverse osmosis purified water equipment

金彩汇1、 The switch is on, but the device does not start:

1. Electrical circuit failure, such as broken fuse and wire falling off

金彩汇2. The thermal protection element is not reset after protection

resolvent:

1. The waterway is under voltage, check the fuse and check the wiring everywhere

金彩汇2. Reset the thermal protection element

3. Check the waterway and ensure the water supply pressure

金彩汇2、 After the equipment is started, the water inlet solenoid valve is not opened:

1. The wiring falls off

2. Internal mechanical failure of solenoid valve

3. Solenoid valve coil is broken

resolvent:

金彩汇1. Check the circuit

2. Disassemble solenoid valve for maintenance

3. Repair or replace the coil

3、 The pump operates but fails to reach the rated pressure and flow:

1. Pump reverse

2. The filter element of the security filter is dirty

金彩汇3. There is air in the pump

金彩汇4. Open the flushing solenoid valve

Solution:

1. Rewire

金彩汇2. Clean or replace the filter element

金彩汇3. Remove the air in the pump

金彩汇4. adjust the pressure after flushing

金彩汇4、 When the system pressure increases, the pump noise is loud

1. Insufficient raw water flow

金彩汇2. Unstable raw water flow

Solution:

金彩汇1. Check the raw water pump and pipeline

2. Check the raw water pump and pipeline and check whether there is leakage in the pipeline

5、 The solenoid valve is not closed after flushing

金彩汇1. Solenoid valve control element and circuit failure

金彩汇2. Mechanical failure of solenoid valve

resolvent:

金彩汇1. Check or replace components and circuits

2. Disassemble, repair or replace the solenoid valve

Vi. undervoltage shutdown

1. Insufficient raw water supply

2. The filter element of the security filter is blocked

金彩汇3. Under pressure caused by improper pressure adjustment and automatic flushing

resolvent:

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 filtered pressure above 20psi

7、 The concentrated water pressure cannot reach the rated value

金彩汇1. Pipeline leakage

2. Flushing solenoid valves are not fully closed

金彩汇3. Leakage of recovery system

resolvent:

金彩汇1. Check and repair the pipeline

金彩汇2. Check and replace the flushing solenoid valve

3. Check and repair the recycling system

8、 The pressure is sufficient, but the pressure display is not in place

金彩汇1. Foreign matters in the pressure gauge hose are blocked

金彩汇2. There is air in the hose

3. Pressure gauge failure

resolvent:

1. Check and dredge the pipeline

2. Remove air

3. Replace the pressure gauge

金彩汇9、 Deterioration of water quality

1. Membrane pollution and scaling

2. Aging and failure of membrane junction seal

resolvent:

1. Carry out chemical cleaning according to technical requirements

金彩汇2. Replace O-ring

3. Replace the membrane

10、 Production decline

1. For membrane pollution and scaling, chemical cleaning shall be carried out according to the technical requirements

2. The water temperature change shall be recalculated according to the actual water temperature to determine the water production.
