Fault Analysis and Elimination Method of CYZ Self - priming Oil Pump
CYZ-type self-suction pump failure analysis and troubleshooting methods to troubleshoot the cause of the pump does not oil 1, the pump casing without liquid or liquid storage less than 2, suction pipe leakage 3, speed error 4, suction stroke is too high or inhalation Pipeline is too long 5, the mechanical seal leakage is too large 6, the suction pipe gas can not be discharged from the outlet 1, plus enough liquid storage 2, check and eliminate leakage 3, adjust the direction 4, reduce suction or shorten the suction pipe 5, Repair or replacement 6, open the outlet valve noise and vibration larger 1, unstable feet 2, pump shaft bending 3, cavitation 4, serious bearing wear 5, there are impurities in the inlet pipe 6, both the pump and the motor Spindle is not the heart 1, reinforcement 2, replacement or correction 3, adjust the working conditions 4, replace 5, remove debris 6, adjust the concentricity less than 1 oil, debris into the suction pipe or impeller flow is blocked 2, the speed is too low 1, exclude blockage 2, adjusted to the rated speed shaft power consumption is too large 1, the flow is too large 2, the speed is too high 3, the pump shaft bending or impeller stuck 4, the pump flow blockage or stuck 1, Export pressure 2, appropriate to reduce 3, replacement or Correct 4, remove the blockage
