Pump failure and troubleshooting: one can not play the liquid 1, there is air in the suction tube 2, suction tube leak 3, pump less than 4 perfusion fluid, sucking pipeline debris clogging 5, pump reverse 6, The suction height is too high Solution 1, re-perfusion of liquid or air 2, check the suction pipe 3, re-perfusion liquid 4, remove clogging debris 5, adjust the steering 6, reduce the installation height II. Flow reasons 1, Damage 2, the speed is not enough 3, there are clogs in the pipeline is blocked Solution 1, replace the impeller 2, check the motor and power supply lines 3, remove clogs Three reasons for excessive power 1, the proportion of the transmission medium is too large 2, Motor axis error is too large 3, mechanical friction solution 1, reducing viscosity or increase perfusion pressure 2, readjustment 3, check where the friction, the overhaul Fourth. Lack of head causes 1, there is air in the medium 2, impeller damage 3 , Speed ​​is not enough 4, the proportion of transmission medium is too large Solution 1, re-perfusion liquid or air 2, replace the impeller 3, check the motor and power supply lines 4, reduce the viscosity or increase perfusion pressure V. Pump vibration causes 1, pump axis versus Machine axis error is too large 2, suction on the high, resulting in cavitation 3, mechanical friction solution 1, readjustment 2, reduce the installation height 3, check where the wear and tear for maintenance VI shaft leakage and seal leakage Reason 1, the shaft end snap ring gap is too large, the ring loose 2, suction on the height is too high, resulting in cavitation 3, mechanical seal, static ring wear, spring pressure 4, mechanical seal, static anastomosis is not good Method 1, adjust the clamp ring screw 2, reduce the installation height 3, change the wear material, adjust the spring 4, adjust the dynamic and static ring
