                  Water pump simple maintenance scheme

                  In the process of the condensate pump in the long run, often appear the pump room bracket bearing wear, bearing wear, pump body crack fracture, water pump cavitation and erosion wear, etc. Appear afore-mentioned problems, the enterprise solution is traditional machining repair after repair welding or brush plating, but both has certain disadvantages: repair welding high temperature thermal stress can not completely eliminate, easy cause material damage, lead to bend or break parts And brush plating coating thickness restrictions, easy to peel, and two methods above are with metal repair of metal, can't change "hard to hard" cooperate relationship, under the force combination, still can cause wear again. First, enterprises should participate in Cairo expo and various professional exhibition to expand influence, enhance the understanding of our high quality products, so as to improve the mechanical and electrical products of high technology content of exports in Egypt. Common leakage phenomenon

                  The proportion of mechanical seal leakage accounted for more than 50% of the total pump maintenance, the operation of the mechanical seal is good or bad directly affects the normal running of water pump, summarized analysis as follows.

                  1. The leakage of periodic

                  (1) pump rotor axial momentum large, secondary seal and shaft interference quantity is big, ring cannot be flexible on the shaft to move. In turn pump, dynamic and static ring wear, without compensation displacement.

                  Countermeasures: in the assembly of mechanical seal, shaft axial momentum should be less than 0.1 mm, auxiliary seal and shaft interference quantity should be moderate, while guarantee the radial sealing, can guarantee on the shaft collar is assembled flexible mobile (press ring to spring can free to bounce back.

                  (2) the sealing surface lubricating oil quantity insufficient cause dry friction or hair the seals.

                  Countermeasures: oil chamber cavity lubricating oil surface height should be added to the above dynamic and static ring sealing surface.

                  (3) the rotor periodic vibration. The reason is that the stator and the upper and lower cover not on or in the impeller and shaft imbalance, cavitation or bearing damage (wear), that will shorten the seal life and leakage.
