Maintenance method of submerged slurry pump


No matter how good the equipment will be used after a certain period of time, the submerged slurry pump is no exception. What should we do when it fails? Let's take a look at it together:

1. When repairing, first remove the pump from the storage tank, remove the motor and the base, remove the lower pump casing, knock off the lower bushing and the impeller (note the anti-corrosion layer on the pump shaft), loosen the upper bearing and sit 6 Hex bolts, then pull the positive pump shaft and bearing parts together for inspection.

2. If the bearing and the pump shaft are replaced, firstly remove the upper end round nut and the coupling of the slurry pump pump shaft, loosen the 12 screws of the upper and lower bearing caps, and drive the bearing up and out.

3. When reassembling after repairing and replacing consumables, see Mounting the bearing housing and bearing together on the upper part of the pump shaft, sealing the upper and lower bearing caps, installing the coupling and tightening the round nut to correct the bending of the pump shaft. Insert the pump with the bearing seat down into the pump body, then install the bearing seat on the intermediate seat, adjust the gap between the impeller and the upper and lower pump casings, and immerse the impeller and the lower bushing with the impeller and the cap with phenolic glue on the pump shaft. After the phenolic cement is completely cured, the lower pump cover is installed. After the assembly is completed, it is normal to rotate the pump shaft by hand on the coupling.

The above is the maintenance tips of the submerged slurry pump. We should always master some maintenance methods, so that we can solve some small problems ourselves. If we can't solve it ourselves, we still need to find a professional to repair.
