Replacement Method of Pump Impeller

After use of the pump impeller may produce some damage to one, the impeller should be replaced.

     1) pump impeller surface cracks.

     2) pump impeller surface due to corrosion, erosion or cavitation to form more holes.

     3) due to erosion caused by pump impeller cover and leaves thinning, affecting the mechanical strength.

     4) pump impeller mouth ring hub more serious partial mill phenomenon without repair value.

     Repair of pump impeller, Repair method of impeller of water pump

     Pump impeller due to sediment erosion, often the formation of grooves or streaks, and sometimes due to cavitation damage, the leaves appear honeycomb holes. If the impeller surface cracks, there are more trachoma or holes, due to erosion leaving the impeller wall thinning, affecting the mechanical strength of the impeller and impeller performance; blade impingement by solid debris or impeller entrance has serious eccentric wear , Should replace the new impeller. If the performance of the pump and the impeller itself has little effect on the strength, you can use welding repair methods. After welding to make use of grinding wheel flat, and do static balance test. In the replacement of axial flow pump blades, should be replaced with a complete set, in the replacement of each blade should be weighed before, and should pay attention to the angle of the installation of the blade to be consistent, so as not to cause axial flow pump vibration.
