WFB series sealing automatic self-priming centrifugal pump troubleshooting
WFB series sealing automatic self-priming centrifugal pump troubleshooting
Failure failure cause elimination method
Automatic control state of the water pump can't start 1, a sensor only poor contact
2, sensor, the bottom installed upside down
3, motor or the fuse is damaged
There is no liquid in 4, RongChi and no 1, restore good contact sensor
2, correct installation of sensors
3, to repair the motor or the fuse
4, check the liquid pool
Water pump can't 1, an automatic parking sensor has been damaged, produce misoperation
2, have particles in the liquid and sensor floating ball, forcing the misoperation 1, replace the damaged sensor
2, flushing float sensor, make its restore flexibility
Automatic and manual unable to convert 1, a button is damaged only 1 and replace damaged button
The manual pump can't start 1, manual button has been damaged
2, 1 motor or the fuse is damaged, replace damaged button manually
2, to repair the motor or fuse
Electric air control valve parts
Failure failure cause elimination method
1, connecting pipe leakage, cannot form a vacuum pump, the suction fluid
2, the piston movement
3, the piston moves, but the pump suction fluid 1, control valve and the pump connection thread is not tight or use for a long time, the corrosion is loose, causing leakage
2, the power can't
3, electric control valve coil damage or damage of electrical components
4, enclosed pad wear
5, sealing pad 1 and the piston stroke is too big, increased on the connecting thread sealing tape, make it not leak or replace corroded connecting pipe
2, check that the electric control valve, power supply cord connected to electric power supply are in good condition
3, replace the electric control valve coil or some components on the circuit board
4, replace the sealing pad
5, adjust the sealing pad and piston stroke
