1 , The pump vibrates violently because of the unbalance of the electric rotor or the bad combination of the coupling, bearing wear and tear, loosening and breaking of some rotating parts, weakness of the pipe support, etc. Adjustments, repairs, reinforcements, straightening, replacement Other ways to deal with. 2, the pipeline leakage or leakage may be due to screw the screw cap is not tight when installed.If the leakage is not serious, in the place of leakage or leakage of cement, wet mud or soft soap, etc. If joints leak, then Tighten the screw cap by hand. Severe water leakage must be reassembled. Imported pump valve 3, bad oil pumping: filling overheating and more due to the packing pressure is too tight, the cooling water can not enter the filler or the shaft surface damage caused .Can take appropriate relaxation of packing, sealing tube blockage and other clean-up.Filler wear must be replaced with a new installation Soak in the oil before the turn, according to the ring into the incision to be staggered, so as to reduce leakage. The last lap packing installed tightly gland, then adjust the tightness. 4, the pump does not absorb the oil for many reasons due to the end of the valve stuck, partial blockage of the water filter, suction height is too high or oil leakage, may also be due to the wrong direction, impeller runner blockage caused by one by one inspection, can be taken separately At the end of the valve, remove debris, correct steering, cleaning impeller and other measures for processing.
