Fault Cause Remedy not pump the liquid [1], the motor turning right malfunction the reason Method of exclusion Pump out of liquid 1, the motor is not steering
2, lack of liquid storage pump
3, there is air leakage in the suction tube 1, adjust the steering
2, add enough liquid
3, remove the gas ã€Pump does not absorb liquid】 1, the end of the valve is not open or blocked
2, suction stroke is too high or inhalation pipeline is too long
3, inhalation of impurities in the pipeline blocked 1, calibrate or replace the bottom valve
2, reduce suction or shorten the pipeline
3, remove clogged debris ã€Insufficient pump flow】 1, impeller damage
2, inhalation or export part is blocked
3, lack of power speed is too low 1, replace the impeller
2, remove clogged debris
3, check the motor speed up [Pump head inadequate] 1, impeller damage
2, There is air in the conveying medium
3, speed is not enough 1, replace the impeller
2, re-perfusion liquid or exclude air
3, check the motor speed up Noise or vibration 1, pump shaft and motor shaft is not the same heart
2, the foot nut loose
3, suction stroke is too high 1, correct the pump and motor concentricity
2, Tighten the bottom nut
3, reduce the installation height Bearing temperature is too high 1, bearing damage
2, deterioration of grease dry or missing 1, replacement
2, replacement, filling grease Pump Leakage 1, mechanical seal damage
2, the connection bolts are loose 1, replacement
2, tighten the various parts of the bolt
2, lack of liquid storage pump
3, inhaled air leakage in the tube 1, adjust the steering
2, add enough liquid
3, remove the gas [pump does not absorb liquid] 1, the end of the valve is not open or blocked
2, suction stroke is too high or inhalation pipeline is too long
3, inhalation of impurities in the pipeline block 1, correction or replacement of the bottom valve
2, reduce suction or shorten the pipeline
3, remove clogged debris [pump less] 1, impeller damage
2, inhalation or export part is blocked
3, low power speed is too low 1, replace the impeller
2, remove clogged debris
3, check the motor to increase speed [pump head less] 1, impeller damage
2, There is air in the conveying medium
3, speed is not enough 1, replace the impeller
2, re-perfusion liquid or exclude air
3, check the motor to increase speed ã€Noise or vibration】 1, the shaft and the motor shaft is not the same heart
2, the foot nut loose
3, suction stroke is too high 1, calibration of pump and motor coaxiality
2, Tighten the bottom nut
3, reduce the installation height [Bearing temperature is too high] 1, bearing damage
2, grease deterioration dry or missing 1, replacement
2, replacement, filling grease [pump leak] 1, mechanical seal damage
2, loose bolt connection phenomenon 1, replacement
2, tighten the various parts of the bolt
