Long axis of submerged pump seal

long axis of the submerged pump sealing

long shaft submerged pump is generally used in bottom pressure straight pipe, sealing characteristics depends entirely on the center of the cap and body are in line with the degree of good or bad, it will face card tight is relying on the tighten the screw nut to create below. Commonly used in PN 0 or less. 6 million mpa.

based on centrifugal impeller geometry appearance leaves, the leaves can be share out bonus after bending, axial and bending before a few kinds. Because after bending leaf can benefit fluid mechanical energy transformation for negative pressure, so it is widely use; Axial leaves the key used in the part of flow pump and non-clogged pumps; Before bending leaves very little use in the long shaft submerged pump. Equipment assembly line long shaft submerged pump start to roller bearing installed on the roller bearing box and arrange ushering bearing separation, will be felt circle in bearing end cover a, c and roller bearing on the box. Followed by bearing end cover b, c in arrange ushering bearing on common anchor bolt tightening.

adjustment screw centrifugal impeller and the space between the front cover, after alignment with the screw nut, anchor bolt fastening. Equipment will motor shores above arrange ushering bearing bolts tightening, on top of the shaft with the axis of prefabricated, connecting shaft and motor USES twisting the screw twist on motor shaft, the motor mounted on its shores, Shared anchor bolt, nut twist.

long shaft submerged pump used in belt conveyer can fine particle suspension and containing liquid crystal fluid. Long shaft submerged pump is applied in recent years rapid development, appeared with a mandatory RunHua sealing ring type long shaft submerged water pump. Because compulsory RunHua cap and body of tu between layers of oil slick. To be stronger in sealing characteristics, easy opening and closing, avoid surface damage.

long shaft submerged pump repair tips: after long shaft submerged water pump overhaul and replacement parts for equipment from scratch, as shown in the bearing seat, bearing in the upper pump shaft, sealed coupling and bearing cover installed and tightened up and down round nut, correction of pump shaft bending, will bring down into the pump body of the bearing, and bearing in the center seat, adjustable impeller and water pump casing space up and down, the impeller and shaft sleeve and impeller and cap with a reuse phenolic daub on the pump shaft, such as phenolic daub cured completely, before the pump cover installed, after the equipment, with his hands on the rolling coupling the pump shaft is normal. Such as replacement of bearing and the pump shaft, pump shaft top down the first round nut and coupling, loosen the long shaft submerged pump bearing cover up and down 12 only screw, with the bearing sit up.
