Приложение:
WQ type sewage pumps widely used in agriculture, architecture,
mine, environment protection and industry, such as drainage slurry,
waste water, which contained short fibre, CZPT fibre, wastepaper,
sand and so on, it is also an ideal equipment for irrigation.

| fault phenomenon | failure cause | elimination methods |
| 1.No CZPT supply or one or two phase CZPT supply is needed | Check all phases of CZPT supply and restore CZPT supply |
|
| 2.Poor contact of ac contactor and burning of coil | Repair or replace contactors |
|
| can not start | 3. The CZPT switch is not closed, malfunction or damaged |
Close the switch and replace it if the CZPT 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 CZPT supply for a few CZPT s, the inverter fault reset before starting. | |
| The manual is normal | 3The frequency converter is damaged | Repair or replace |
| Automatic transmission failure | 4.Pressure switch damage | Repair or replace |
| 5The pressure transmitter is damaged | Repair or replace | |
| 6.Switch failure | Repair or replace | |
| Pump CZPT – 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 CZPT |
Too much flow, impeller wear |
Check whether the pump shaft is bent, replace the impeller, close the outlet valve to reduce the flow |
