Fan cover manufacturers introduce common problems and solutions of fans

First of all, cracks or fractures in equipment components are often caused by excessive operation of fan components due to casting, machining defects, or internal stress. The conventional repair method is welding, but welding often causes thermal deformation or thermal stress on the parts. It is thin-walled parts, and some parts are made of difficult-to-weld materials such as cast iron, aluminum alloy, and titanium alloy. There are also some occasions prone to explosion hazards, such as the petrochemical industry. It is not easy to use welding repair methods, which severely restricts the fan The maintenance level of the equipment by the cover manufacturers increases the operating cost of the enterprise.

Secondly, most of the equipment parts are made of metal materials. Due to their high strength and high hardness, parts of the parts are subjected to vibration, impact and other composite forces during production and operation, and part of the impact deformation becomes deformation, the recovery stress is reduced, and the gap is formed. Coordination that meets operating requirements leads to wear of transmission components. Traditional repair methods include surfacing welding, thermal spraying, and brushing.

One point is the corrosion problem mentioned by the fan cover manufacturer, the damage and deterioration caused by the fan under the action of the environmental medium. This problem will not only cause economic losses for enterprises, but also have certain hazards to safety and the environment, as well as deplete natural resources. In response to this problem, frequent replacement of equipment components is currently a temporary method adopted by enterprises, and the equipment is affected by materials and processing techniques, and has high general value.
