Top ten failures and maintenance methods of reverse osmosis equipment

• RO reverse osmosis purified water equipment ten failures and maintenance methods
• the switch is on, but the device does not start
• Electrical line failure, such as bad insurance, wire fall off
• The thermal protection element is not reset after protection
• Solution:
• Water undervoltage, check the insurance, check the wiring
• The thermal protection element is reset
• Check waterways to ensure water supply pressure
• After the equipment is started, the water inlet solenoid valve is not opened
• Cables are disconnected
• The internal mechanical of the solenoid valve is faulty
• The solenoid valve coil is broken
• Solution:
• Check the cable
• Remove the solenoid valve for repair
• Repair or replace the coil
• pump operation, but not up to the rated pressure and flow
• Pump reversal
• The filter element of security filter is dirty
• There is air in the pump
• Flush the solenoid valve to open
• Solution:
• Reconnect cables
• Clean or replace the filter element
• Remove the air from the pump
• Adjust the pressure after rinse
• when the system pressure rises, the pump noise is large
• The raw water flow is not enough
• Raw water flow is unstable
• Solution:
• Check the original water pump and pipes
• Check whether the original water pump and pipes leak
• The solenoid valve is not closed after washing
• The control component and circuit of the solenoid valve are faulty
• The solenoid valve is faulty
• Solution:
• Check or replace components and circuits
• Remove the solenoid valve and repair or replace it
• under voltage stop
• Raw water is in short supply
• The security filter element is blocked
• Improper pressure adjustment, automatic flushing caused by underpressure
• Solution:
• Check whether the raw water pump and pretreatment system are working
• Clean and replace the filter element 3. Adjust the system pressure to the best state and maintain the post-filter pressure above 20psi
• the concentrated water pressure is not up to the rating
• Pipeline leaks
• The flushing solenoid valve is not fully closed
• The recycling system leaks
• Solution:
• Check and repair pipes
• Check and replace the flushing solenoid valve
• Check and repair the recovery system
• the pressure is enough, but the pressure display is not in place
• The pressure gauge hose is blocked with foreign bodies
• There is air in the hose
• The pressure gauge is faulty
• Solution:
• Check and unclog pipes

2. Air out

• Replace the pressure gauge
• the water quality is worse
• Membrane contamination and scaling
• The seal of the membrane junction fails due to aging
• Solution:
• Chemical cleaning shall be carried out according to technical requirements
• Replace the O-ring
• Replace the membrane
• Decline in output
• Chemical cleaning shall be carried out according to technical requirements for membrane contamination and scaling
• Water yield is determined by recalculating the change of water temperature according to the actual water temperature.
