Drainage pump does not start after the start of water: the pump air or gas into the tube, or the bottom valve is not strict Irrigation filling, vacuum pump filling serious leaks, gate or lap closed lax. Countermeasures: remove debris, replace damaged rubber pads, change the direction of the valve; press or replace the new filler, close the gate valve or the door; increase the amount of irrigation until the deflation plug is not bubble up; replacement Cracked pipe; lower head, the pump nozzle into the submerged 0.5 meters. Start pump does not turn: packing is too tight or between the impeller and the pump is clogged with debris, or the pump shaft, bearings, leakage ring rust live, or serious bending of the pump shaft. Countermeasures: relax the filler, clear the diversion trough; open the pump body to remove debris, rust; remove the pump shaft to correct or replace the new pump shaft. Pump heat bearing damage: Rolling bearing or bracket cover gap is too small; shaft bending or two axes are not the same; tape is too tight; lack of oil or poor oil quality; impeller balance hole plug, impeller out of balance, increasing the direction Thrust on one side. Countermeasure: Change the bearing; Remove the back cover, install the gasket between the bracket and the bearing seat; Adjust the pump shaft or adjust the concentricity of the two shafts; Adjust the tightness of the tape appropriately; Fill clean the butter, 60% of the gap; remove the blockage in the balance hole. Insufficient flow after starting: insufficient speed or belt slippage, resulting in low speed; axial pump blade mounting angle is too small; insufficient lift; suction stroke is too high; bottom valve, pipe and impeller partial blockage or impeller defect; serious. Countermeasures: Adjust the blade angle, reduce the pump installation position; to restore the rated speed, remove the belt grease, adjust the belt tightness; seal the pump leak, compaction packing; remove clogs, replace the impeller; Department.
