The pump does not turn when starting Cause: The packing is too tight or clogged with clogs between the impeller and the pump body; the pump shaft, bearings and leakage ring rust live; the pump shaft is severely bent. Remedy: Loose packing, clear the diversion channel: open the pump body to remove debris or rust; to correct the curved shaft or a new pump shaft.
After the start of the pump is not water causes: the pump air or inlet gas; bottom valve lax irrigation is not satisfied, the vacuum pump filling a serious leak; gate valve or rattling closed lax. Remedy: remove debris, replace the damaged rubber mat, change the direction of the valve; press or replace the new packing, close the gate valve or the door; increase the amount of irrigation until the deflation plug does not bubble; replace with Cracked tube water; reduce head, the pump nozzle pressed into the water 0.5 meters.
Flow shortage reasons: the actual head of the pump exceeds the allowable head; speed does not support or belt slippage, low speed; axial pump blade mounting angle is too small; suction stroke is too high; the end of the valve, piping and impeller partial plug or impeller defect; Water leakage is serious. Remedy: Reduce the lift, restore the rated speed, remove the belt dirt and adjust the belt tightness; adjust the blade angle, reduce the pump installation position; tighten the gland, seal the pump leakage, compression packing or replacement packing; clear the blockage, Replace the impeller; replace the leak ring, plug the leak.
Flow from big to small Cause: Mesh or bell mouth is gradually blocked by debris; dynamic water level decreases, water depth submerged enough. Remedy: Remove debris, increase the depth of the bottom valve into the water.
Run out of water due to interruption: there is blockage of debris or water inlet; packing wear, loose, blocked water seal tube; Impeller was broken or loose; Remedy: remove clogs, replace the filler, clear the guide pipe groove, the correct installation of water seal ring; tighten or replace the impeller; reduce the pump installation location, or until the water level rise and then boot.
Power consumption is too large Reason: high speed; pump shaft bending; leaves around a debris; head is too high. Remedy: Adjust the appropriate speed; correct pump shaft; remove debris; try to reduce head.
