Maintenance plan of water pump

In the process of long-term operation of the water pump, the bearing chamber of the water pump bearing frame is worn, the bearing position is worn, the pump body is cracked and broken, the water pump is cavitation, and scouring wear. After the above problems occur, the traditional solution of the company is repair welding or machining and repairing after brush plating, but both have certain drawbacks: the thermal stress generated by the high temperature of repair welding cannot be completely eliminated, and it is easy to cause material damage and cause parts to bend or break. ; But electric brush plating is limited by the thickness of the coating, which is easy to peel off, and the above two methods use metal to repair the metal, which cannot change the "hard-to-hard" coordination relationship. Under the combined action of various forces, it will still cause re-wear.

Contemporary Western countries mostly use polymer composite repair methods for the above problems, which have super adhesion, excellent compressive strength and other comprehensive properties. It can be repaired by polymer materials without disassembly and machining. There is no thermal stress of repair welding, and the repair thickness is not limited. At the same time, the metal material of the product can absorb the shock and vibration of the equipment, avoid the possibility of re-wear, and greatly extend the service life of the equipment components. Enterprises save a lot of downtime and create huge economic value.
