Symptoms the reason Elimination method Mixed flow pump does not water 1, insufficient water or vacuum pump suction enough air inside the pump 2, water pipeline leak 3, suction stroke is too high 4, the pump is not steering 5, the total height of water exceeds the provisions 1, continue to pump or pump 2, check and exclude 3, lower the pump installation height 4, change the steering 5, lower Mixed flow pump water is interrupted 1, too much air bubbles 2, inlet pipe to store air 3, into the water pipe leaks 4, into the water pipe or impeller is clogged with debris 1, increase the depth of the inlet pipe into the water 2, exhaust 3, adjust the litter, tighten the bolt 4, remove debris Out of water 1, the inlet pipe or impeller is clogged with debris 2, speed is not enough or not enough power 3, water is too high 4, pump cover and impeller wear, sealing gap is too large 5, the gate valve is too small or the check valve is obstructed 6, Immersed into the water inlet depth is not enough 1, remove debris 2, adjust 3, lower 4, repair or adjust the paper pad 5, proper opening gate valve, remove obstacles 6, increase the depth of immersion Power consumption is too large 1, the speed is too high 2, drive shaft bending 3, packing pressed too tight 4, bearing wear or damage 5, the belt is too tight 1, lower 2, straighten 3, release the gland nut or filler to take out some flat

stroke is too high, cavitation occurs 6, pump inhalation of debris 1, find correct 2, straighten or replace 3, tighten 4, excluded 5, reduce the installation height 6, exclude Bearing fever 1, lack of oil 2, the quality of lubricants is not good, not clean 3, the shaft center is not right 4, bearing wear 5, the belt is too tight 1, cheer up 2, replace the oil, cleaning bearings 3, find correct 4, replace the bearing 5, appropriate to relax Filler fever 1, the packing is too tight and uneven tightness around 2, the packing pressure deflection, the bearing sleeve friction uneven 1, Loosen the gland nut to adjust the packing tightness 2, release the gland, re-tighten again Leakage at the packing too much 1, the packing is not compressed 2, improper packing device 3, packing specifications do not match 4, sleeve wear 1, appropriate screwing gland nut 2, adjust the filler buckle, so that a certain angle of staggering 3, replace the packing 4, with the shaft sleeve Symptoms the reason
