The sewage pump is a high-efficiency and energy-saving sewage pump which has been successfully developed by domestic and foreign advanced technology. The pump has the characteristics of non-blocking design and high efficiency. The unit unit wastewater discharge, the urban sewage treatment plant discharge system, the sewage drainage station in the residential area, Subway, basement, civil air defense system drainage station, hospital, hotel, high-rise building sewage discharge, municipal engineering, drainage of mud in construction site, sewage discharge from farms and irrigation of rural farmland, water supply device for water plant, mine exploration and water Processing equipment package. phenomenon Pipeline sewage pump causes Pipeline sewage pump elimination method Pipeline sewage pump does not start and operate Voltage is too low Increase the voltage or increase the voltage and then use it again. Feeder has open circuit Look at the fuse and wiring and replace it The impeller is stuck by debris Exclude debris No axial clearance between the two coupling halves and jamming Adjust the axial clearance between the two coupling halves to 0.5 mm The impeller and the volute are in close contact Reassembly, separation of the impeller and volute Nut off and flat key damage makes the impeller slip Install flat keys and nuts Coupling flat key damage Change flat key Insufficient flow in the sewage pump Motor speed is lower than rated speed Increase motor speed The suction port is blocked, the mud pit is not deep, and the pump does not suck the mud. Remove the suction block and move the pump so that the volute is completely buried in the mud and manure The mud pipe is blocked Check the pipe and take out the blocker The medium is too thick or the supply is not good Dilute the medium to increase the supply Large leakage Check the cause of the leak and replace the part that caused the leak Impeller broken Exchange impeller The lift is too high, the transport is too far Reduce head and shorten conveying distance Swiveling opposite Change motor rotation There are debris around the impeller Exclude debris Pipeline sewage pump noise and vibration The temperature of the liquid is too high Lower liquid temperature There is a hard object in the working fluid Control the size of the pump debris, encryption filter Air infiltration Deep volute There are debris in the volute Exclude debris The nut is loose Tighten the nut Impeller and volute friction Check the pump assembly and adjust it The bearing is damaged or less oil Change bearings or refuel The pump shaft is not concentric with the motor and the shaft is bent Adjust the concentricity, correct the axis Pipeline sewage pump overload Concentricity change, bearing damage, shaft deformation Correct parts, change bearings Improper assembly of the pump parts, difficulty in turning, foreign matter stuck Reassemble, remove foreign objects Swiveling opposite Transform motor rotation The head is too low and the flow is too large Try to avoid long-term use The article is from the production department of Shanghai Equan Pump Co., Ltd. , welcome to read and learn. The sewage pump (submersible sewage pump , self-priming sewage pump and pipeline sewage pump ) produced by our factory has reached the international advanced level.

The technical department of our factory: The four aspects of the pipeline sewage pump are not started and operated, the flow is insufficient, the vibration is large, and the overload is analyzed as follows:
