Traditional repair methods: mainly brush plating, spraying, surfacing or replacement. Brush plating is easy to delaminate, the replacement cost is high, and it is difficult to solve the problem.
Repair with Meijiahua technology: Fuji Lan 22 1 1F polymer composite material repair.
Polymer composites are materials composed of polymer, metal or ceramic ultrafine powder, fiber and so on. Under the action of curing agent and curing accelerator. Various materials learn from each other's strong points in performance, resulting in synergistic effect, which makes the comprehensive performance of composite materials superior to raw materials. It has strong adhesion, mechanical properties and chemical corrosion resistance, so it is widely used in the repair of mechanical wear, scratches, pits, cracks, leaks and casting sand holes of metal equipment, as well as the chemical corrosion protection and repair of various chemical storage tanks, reaction tanks and pipelines.
Wear of bearing position of 380Kw motor shaft
After the motor shaft bearing is damaged, the bearing position is worn. After the problem occurs, it should be repaired by traditional methods such as repair welding, brush plating and machining. However, the thermal stress caused by high temperature of repair welding can not be completely eliminated, and it is easy to bend or break; Brush plating is limited by the thickness of the coating and is easy to peel off; Moreover, all the above methods use metal to repair metal, which can not change the matching relationship of "hard to hard", and will still cause re-wear under the comprehensive action of various forces.
Bearing position and bearing chamber wear of 900Kw motor
During the long-term operation of the motor, due to the influence of various factors, the wear of the bearing chamber is very common. After the problem occurs, the traditional method cannot be solved on the spot, and it must be repaired or replaced through external cooperation. Moreover, using metal to repair metal can not change the "hard to hard" coordination relationship, and under the comprehensive action of various forces, it will still cause re-wear.
Wear of bearing chamber of 90Kw motor
During the long-term operation of the motor, bearing cavity is very common due to various factors. After the problem occurs, the traditional method cannot be solved on the spot, and it must rely on scrapping and replacement.
