Maintenance method of centrifugal pump

Centrifugal sand pump has been designed and developed for petroleum drill in solid control equipment. It adopts the axial sucking structure and all the hydraulic components are friction proof cast iron, which is suitable for delivering the corrosive liquids with suspended particles in well drilling or other similar liquids. When designing the sand pump. Its specifications were fully thought that the completesolid control equipment can work under the best operating mode. It is endowed with high commonality of parts, operating reliability, durability and convenient maintenance etc.
The detailed maintenance method of centrifugal pump
1. Impeller: It must be renewed if serious cavitation (in particular the main vanes) and excessive damage.
2. Shaft: Repair and maintain or renew it if the run out is over 0.05 mm, the location of lip seal had been seriously bruised and the surface of shaft had been damaged.
3. Shaft sleeve: Please renew it if rough surface and serious damage.
4. Lip Seal: The dismantled lip seal must be changed.
5. Ball Bearing: For the bearing which is too wearing, and too tight, loose or with noise when operating, sure to renew it.
6. All the parts and particularly the rotating ring of mechanical seal, ‘0’ sealing groove, thread, sealing face, bearing and its lubricating location must be carefully cleaned.
7. When assembling the inboard bearing, the two bearings should be back to back, sure to buckle the lock washer after screwing the locknut.
8. A thin layer of antifriction should be smeared on the shaft before fitting the shaft sleeve.
9. The packing gland cannot be screwed too tight and keep the liquid leaking drop by drop, or the packing will be burned down when the pump operating.
10. The assembling can be proceeded as the opposite sequence and pump shaft should smoothly rotate after assembling.
