Common faults and troubleshooting of coater

Coating machine drive part wear

During the operation of the coater, there are often problems of the wear of the transmission parts, such as the wear of the drying cylinder head of the coater, the wear of the roll bearing chamber and so on. The traditional repair methods include overlay welding, thermal spraying, brush plating and so on, but all of them have some disadvantages: overlay welding will make the surface of parts reach a very high temperature, cause deformation or cracks, and even lead to shaft fracture when it is serious; the electroplating coating can not be too thick, and the pollution is serious, and the application is limited. With the development of technology, polymer composite materials can be used to solve the above problems. Among them, the more mature technology system of meijiahua is used. The material has a good adhesion and compressive strength, which can avoid dismantling and repairing the coater wear on site. At the same time, because of its metal deficiency, it can absorb the impact vibration of the equipment and avoid the secondary wear.

Damage to concrete foundation of coater

Due to the influence of corrosion, aging, equipment vibration and other factors, the coating machine will also cause damage to the concrete base and other parts, resulting in the loosening of the bolts fastening the equipment, which seriously affects the production. The traditional concrete pouring method will prolong the repair time greatly, which is difficult for enterprises to accept. Polymer composite material also solves this problem very well. The impact resistance and compressive strength of the material itself is much greater than the current concrete material, and it also adheres to steel and other rough surfaces, which can cure rapidly. It is a new scientific research achievement to repair the damage of concrete base of coater.
