Centrifugal pump three maintenance methods

[Asia pump network] Xiaobian today and we introduce the next three centrifugal pump maintenance methods. We pay attention to the maintenance process, you can extend the life of centrifugal pumps. Centrifugal pump three maintenance methods Centrifugal pump first-class maintenance Centrifugal pump cumulative operation (1000 ± 24) h, the duty by a maintenance personnel, the main contents, 1, check the coupling (back wheel, the wheel) In good condition, tighten the bolt, improve health work. 2, replace or fill with sealing packing, so gland parallel press-in, gland packing box from the end face distance of not more than 5mm, no more than 30 drops per minute leakage. 3, check and clean the bearings, add or replace the lubricating oil. 4, check and clean the import filter, proofreading import and export pressure gauge. 5, check the motor bearings and raise the oil. 6, check and tighten the bolts of the various parts of the unit to deal with the leakage of the various sections of the pipeline. Centrifugal pump secondary maintenance Centrifugal pump cumulative operation (3000 ± 24) h, the maintenance of large classes or mechanics mainly by the duty staff with secondary maintenance operations. 1, will be a maintenance job completed all over again. 2, measuring and checking the bearing clearance, if necessary, to adjust and replace, to ensure that the gap in line with the provisions. 3, check the work of the pump string (balancing disk gap). 4, check the coupling of concentricity. Centrifugal pump three maintenance Centrifugal pump cumulative operation (10000 ± 72) h, by the pump repair professionals at the scene for three maintenance operations. 1, remove and connect all the pipe and pump outlet flange, and inspection and cleaning, to be unimpeded, no damage. 2, remove the pump: After loosening the tile cover bolts, remove the tile and the tile, remove the tile frame and the tail cover.
