LSK electric power frequency pump control cabinet is assembled according to electrical wiringquirements of switchgear, measuring instruments, protective appliances and auxiliary equipment in closed or semi-closed metal cabinets or screen, the layout should meet the requirements of
the normal operation of the power system, easy maintenance, does not endanger the person And the surrounding equipment safety. In normal
operation, the circuit can be switched on or off by manual or automatic switch. Fault or abnormal operation with the protection of electrical cut off the circuit or alarm. By measuring instruments can display a variety of parameters in operation, but also to adjust some of the electrical parameters, deviation from the normal state of work for the prompt or signal. Commonly used in the hair, with substations.
| 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 | 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 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 |
