Reasons: slurry pumps speed is too high; slurry pumps slurry pumps shaft bending or spindle and motor shaft misalignment or not parallel; inappropriate choice of slurry pumps head; slurry pumps suction sand or obstructions; motor ball bearing damage, etc. .
Solutions:Check circuit voltage and reduce slurry pumps speed; the relative position of the spindle correction or adjustment slurry pumps slurry pumps and motor; slurry pumps lift the appropriate choice; clean up sediment or blockage; replace the motor's ball bearings.
