Submersible pump wells with common faults and troubleshooting methods

Well pump with submersible well is an important equipment for deep well water supply, when used, the whole unit dives into the water to extract the groundwater to the surface. Well submersible pump common faults and troubleshooting methods Submersible pump common cause of the fault and its troubleshooting Symptom: No water, less water or intermittent water. Reason: ① motor reversal; ② motor does not start; ③ water level lower than the suction inlet; ④ pipeline or connection serious leaks; ⑤ pump seal ring or impeller severe wear and tear bad; ⑥ motor and pump coupling sleeve ran . Remedy: ① exchange contact location; ② exclude the line fault, check the voltage; ③ increase the pump or replace the water pump; ④ demolition pump troubleshooting, eliminating the failure; ⑤ replace the seal ring or impeller; Symptom: traffic is reduced. Causes: ① seal ring is worn; ② filter is blocked; ③ Yang pipe or shell between the water leakage. Remedy: ① demolition pump replacement seal ring; ② demolition pump repair drainage network; ③ demolition pump troubleshooting, troubleshooting. Symptom: Unit violent vibration. Reason: ① pump shaft bending; ② pump and motor bearings wear too much. Remedy: ① disassemble the pump shaft or replacement; ② remove the pump or motor, bearing repair. Symptoms: ammeter pointer swing large. Causes: ① moving water level down to the pump inlet; ② flow is too large, causing the pump rotor string. Remedy: ① increase Yang pipe or replace the pump; ② small valve to reduce the amount of water. Symptoms: insulation resistance dropped to 0.5MΩ below. Causes: ① cable connector is not high quality; ② motor insulation damage; ③ cable damage. Remedy: ① reconnect the cable connector; ② repair motor windings; ③ repair or replace the cable. Symptoms: start the motor does not turn, there is a buzz. Reason: ① motor single-phase operation; ② bearing bite axis. Remedy: ① Check the power cable to find out the phase; ② repair or replace the bearing. (Editor: Li Juan QQ:) Recommended reading: Acting procurement
