Pump industry suppliers to tell you: the balance should be paid attention to multistage pump is disassembled

since the balance of multistage pump remove items that should be paid attention to when

1, parking in the parking order;

2, liquid in the pump housing ( Including the cooling water) Should be put off; When bearing components is thin oil lubrication, should put off lubricating oil;

3, down impede remove the attached pipeline, such as balance pipe, water pipe line and the lead;

4, the manufacturing precision of should strictly protect the removed parts from damage, remove the wear of rod at the same time should use the middle block padding, in order to avoid the middle check loose mouth sinking shaft bending.

mining wear-resisting multistage pump disassembly sequence

1, unscrewing out side bearing bolt on the end cover and water period, end cap, bearing body between the three components of the connecting bolt, unloaded and bearing end cover, bearing body bearing parts;

2, turn round nut and so on the shaft under unloading bearing inner ring, bearing gland and collar, remove packing ( Including the packing gland, packing ring, packing, etc) ；

3, in turn to unload a O ring on the shaft, shaft sleeve, the balance disc peace key after discharged out of the water at the end of the period, guide vane, gimbal ring

4, after peace key level at the end of the impeller, landed in the middle, guide vane; According to this, in turn, remove the impeller at all levels, middle, and guide vane, until grade impeller before unloaded;

5, after unloading water pump coupling, unscrewed the fill section and bearing body coupling nut and bearing gland bolts on after discharged water period of side bearing parts;

6, the shaft from the water pumped section, screw shaft fixed nut, in turn bearing inner ring, O ring, shaft sleeve, etc to unload;

7, using sliding bearing of the pump, the disassembly sequence are basically the same, only when removing the bearing components is slightly different.
