水泵常见故障的排除方法_泵浦资讯网_百度空间

Pump does not start to reason: too tight or filler between the impeller and the pump body and the plug was stuck debris; shaft, bearings, ring rust live leak; serious bent shaft. Troubleshooting: relax fill flume clear: open the pump body to clear debris or rust; bending correction or replacement of the pump shaft axis.
     After the water pumps can not start because: pump air or gas inlet; valve closed at the end of dissatisfaction with poor irrigation, fill a serious vacuum leak; valve or strict door closed. Troubleshooting: debris removal, replacement of damaged rubber pad to change the direction of the valve; pressed or replacement of the fill, close the gate valve or door; increase the amount of water until gas bubbles are not exposed to plug Office; replacement There are cracks in water management; reduce the head, will pump pressure into the nozzle of 0.5 meters underwater.
     Inadequate flow of reasons: the actual lift pump lift more than allowed; speed does not support or belt slip, low speed; axial flow pump blade installation angle is too small; smoke way too high; at the end of valve, pipe and impeller Impeller partially plugged or defect; water possession of a serious leak. Excluded methods: reduce the head, the restoration of the rated speed, to remove dirt and transfer belt, a good belt tightness; tuned blade angle to reduce the pump installed; screw pressed cover, water pump seal leaks, fill or replace the fill compaction; clear plug material to replace the impeller; replacement ring leak, plug the leaks.
     Flow by the change of small reasons: filter or debris gradually plug bell; move to lower the water level, insufficient water depth of submerged inlet. Troubleshooting: debris removal, increase in water depth at the end of valve.
     Interruption of the operation of the reasons for water: water pipe, or there is debris blocking; packing wear and tear, loose tube plug seal; impeller was broken or loose; move the sharp drop in water level. Troubleshooting: plug removal and replacement of fill, dredge water pipe trench, the correct installation of seal ring; fastener or replacement of the impeller; reduce pump installation, or when the water level rose after the boot.
     Too much power consumption reasons: excessive speed; shaft bending; leaf debris around there; head high. Rule out the method: the right to adjust the speed; correction shaft; removal of debris; to reduce lift.
