Our company targets the followingROProvide maintenance services for related products centered on membrane separation

　　Such as reverse osmosis equipment maintenance, pure water filling production lines, deionization equipment

　　We provide dedicated and excellent after-sales service for the maintenance of high-purity water equipment and other issues.

　　And provide related accessories and consumables, such as reverse osmosis membranes, at prices lower than the market rate.

　　Quartz sand/Activated carbon filter materialPPFilter elements, scale inhibitors, etc.

　　All users and distributors are welcome to call for consultation.

　　1The switch is on, but the device does not start

　　①Electrical circuit faults, such as broken fuses or fallen wires

　　②The thermal protection element failed to reset after protection

　　③Under-voltage in the waterway         Check the fuse and inspect all the wiring

　　②Reset the thermal protection element

　　③Check the waterway to ensure the water supply pressure

　　2After the equipment was started, the water inlet solenoid valve did not open

　　①The wiring has come loose.

　　②Mechanical failure inside the solenoid valve

　　③The coil of the solenoid valve is broken ①Check the circuit

　　②Disassemble the solenoid valve for maintenance

　　③Repair or replace the coil

　　3The pump is running, but it fails to reach the rated pressure and flow rate

　　①The pump is reversing.

　　②The filter element of the security filter is dirty

　　③There is air in the pump.

　　④The flushing solenoid valve is open ①Reconnect the wire

　　②Clean or replace the filter element

　　③Expel the air inside the pump

　　④Adjust the pressure after rinsing is complete

　　4When the system pressure rises, the pump makes a lot of noise

　　①The flow of raw water is insufficient

　　②The flow of the raw water is unstable

　　①Inspect the raw water pump and pipelines

　　②Inspect the raw water pump and pipelines, and check if there is any leakage in the pipelines

　　5 The solenoid valve was not closed after flushing

　　①Faults in the control components and circuits of the solenoid valve

　　②Mechanical failure of the solenoid valve ①Inspect or replace components and circuits

　　②Disassemble the solenoid valve or replace it

　　6Under-voltage shutdown

　　①The supply of raw water is insufficient

　　②The filter element of the security filter is clogged

　　③Improper pressure adjustment causes under-pressure during automatic flushing ①Check whether the raw water pump and the pretreatment system are working

　　②Clean and replace the filter element

　　③Adjust the system pressure to the optimal state to maintain the post-filtration pressure at20psiAbove

　　7The concentrated water pressure fails to reach the rated value

　　①Pipeline leakage

　　②The flushing solenoid valve was not fully closed

　　③Leakage of the recycling system ①Inspection, pipeline

　　②Inspect and replace the flushing solenoid valve

　　③Inspect and recycle the system

　　8The pressure is sufficient, but the pressure display is not accurate

　　①Foreign objects are blocking the pressure gauge hose

　　②There is air in the hose.

　　③Pressure gauge malfunction ①Inspect and unblock the pipelines

　　②Expel the air

　　③Replace the pressure gauge

　　9The pressure difference between the front and rear sections of the membrane is too large Membrane fouling and clogging Carry out chemical cleaning in accordance with technical requirements

　　①Membrane fouling and scaling

　　②The sealing of the film junction head has aged and failed ①Carry out chemical cleaning in accordance with technical requirements

　　②ReplaceO"Profile ring

　　③Replace the membrane

　　10Decline in output

　　①Membrane fouling and scaling shall be chemically cleaned in accordance with technical requirements

　　②Water temperature variation Recalculate and determine the produced water based on the actual water temperature

　　Repair reverse osmosis equipment Repair the pure water equipment Repair high-purity water equipment
