phenomenon the reason Elimination method phenomenon the reason Elimination method Consumption power Rate is too large 1 . Submerged pump packing pressed too tight 2. impeller and shell friction 3. The motor axis is offset from the pump shaft centerline 4. The pump shaft is bent or tilted 1. Adjust the packing gland 2. Adjust the axial clearance 3. Find the coupling 4. The adjustment or replacement Pump out liquid 1. Suction tube or imported plug 2. The liquid level is lower than the working impeller 3. The pipe contains air 4. The motor is not turning 1. To eliminate the phenomenon of congestion 2. Fill the tank with liquid 3. Exclude pipe gas 4. change the direction Traffic is not foot 1. impeller wear 2. Import and export pipeline blocked 3. The impeller excessive wear of the sealing ring 4. The impeller off 1. Change the impeller 2. Clean the import and export pipelines 3. Replace the seal ring 4. Heavy by the assembly Pump vibration There is noise 1. The center line of the motor and the pump shaft centerline misalignment liquid 2. The pump impeller and the friction 3. Bearing clearance is too large 4. Mandrel bending The impeller wear, corrosion, Rotor is not balanced 1. Find the two-axis center line 2. Adjust the draw clearance 3. Replace the bearing 4. Straightening 5. Replace the impeller or rotor to find balance Bearing too heat 1. Bearing assembly is not reasonable 2 bearing box lack of oil or oil quality    3. Bearing wear or corrosion 4. The motor shaft and pump shaft are not on the same center line 1. Reassemble 2. Clean the bearings, refuel or replace the oil 3. Replace the bearings to solve the leakage 4.
