Fault Phenomenon Failure Cause Elimination Methods
  1. No power supply or one or two phase power supply is needed
Check all phases of power supply and restore power supply

 
  2. Poor contact of ac contactor and burning of coil
Repair or replace contactors

 
Can not start 3.
The power switch is not closed, malfunction or damaged

 
Close the switch and replace it if the power indicator does not turn on
  4.
Thermal relay trip or damage

 
Check whether the motor is blocked, find out the reason and eliminate it.Manual reset is replaced if it cannot be started
  Water level is too low
Put water in the sink

 
  The motor burned
Repair or replace the motor

 
  1. Line is loose
Check wiring and tighten connectors

 
  2. Frequency converter malfunction Check the fault content, check the cause according to the frequency converter manual, and restart after reset.Or disconnect the inverter power supply for a few seconds, the inverter fault reset before starting.
The manual is normal 3. The frequency converter is damaged Repair or replace
Automatic transmission failure 4. Pressure switch damage Repair or replace
  5. The pressure transmitter is damaged Repair or replace
  6. Switch failure Repair or replace
Pump non - suction pressure gauge pointer to beat violently Insufficient water supply for perfusion, air leakage at the connection between pipeline and instrument Check pipeline and bottom valve, refill water diversion. Tighten air leakage

The pump consumes too much power

 

Too much flow, impeller wear

 
Check whether the pump shaft is bent, replace the impeller, close the outlet valve to reduce the flow
