Filter press pump failure and troubleshooting reasons Solution can not play a liquid 1, the suction tube air 1, re-perfusion liquid or 2, suction tube leakage 2, check the suction line 3, the pump perfusion liquid less than 3, reperfusion Liquid 4, Suction block is clogged with debris 4, Remove clogged debris 5, Pump reversal 5, Adjusting steering 6, Suction height is too high 6, Reducing installation height Less than 1 flow, Impeller damage 1, Impeller replacement 2, Speed Insufficient 2, Check the motor and power supply lines 3, Clogged with debris in the pipeline 3, Remove the clogged debris power is too large 1, The proportion of the transmission medium is too large 1, Reduce the viscosity or increase the filling pressure 2, The pump axis and the motor axis error Large 2, readjustment 3, mechanical friction 3, check where the friction, the maintenance lift less than 1, there is air in the transmission medium 1, re-perfusion liquid Or exhaust air 2, impeller damage 2, replace the impeller 3, speed is not enough 3, check the motor and power supply line 4, the proportion of transmission medium is too large 4, reduce viscosity or increase perfusion pressure pump group 1, pump axis and the motor axis error Large 1, readjust 2, suck the height, produce cavitation 2, reduce the installation height 3, there is mechanical friction 3, check where the wear and tear, shaft shaft leakage and seal leakage inspection 1, the shaft end snap ring clearance Large, loose ring 1, adjust the ring screw 2, suction height is too high, resulting in cavitation 2, reduce the installation height 3, mechanical seal, static ring wear, spring pressure 3, replacement of wear material, adjust the spring 4, Mechanical seal, static ring is not good fit 4, adjust the dynamic and static ring
