During the long-term operation of the pump, the wear of the bearing housing of the pump bearing frame, the wear of the bearing position, the crack cracking of the pump body, the cavitation erosion of the pump, and the erosion wear often occur. After the above problems occur, the traditional solution of the enterprise is repair welding or machining repair after brush plating, but both of them have certain disadvantages: the thermal stress caused by the high temperature of repair welding cannot be completely eliminated, which is easy to cause material damage, leading to bending or fracture of parts; However, brush plating is subject to the coating thickness, which is easy to peel off, and the above two methods are both metal repair methods, which cannot change the "hard to hard" coordination relationship, and will still cause re wear under the combined effect of various forces. In the contemporary western countries, polymer composites are often used to repair the above problems. They have super adhesion, excellent compressive strength and other comprehensive properties. It can be repaired with polymer materials without disassembly or machining. It is not affected by the thermal stress of repair welding, and the repair thickness is not limited. At the same time, the metal materials of the product do not have the flexibility, which can absorb the impact and vibration of the equipment, avoid the possibility of re wear, and greatly extend the service life of the equipment components, saving a lot of downtime for enterprises and creating huge economic value.
