The stainless steel fan is a machine that relies on the input mechanical energy to increase the pressure of the gas and discharge the gas. It is a driven fluid machine. Stainless steel fans are widely used in ventilation, dust extraction and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings; ventilation and air induction of boilers and industrial furnaces; cooling and cooling in air conditioning equipment and household appliances ventilation;

Grain drying and delivery; wind tunnel wind source and hovercraft inflation and propulsion. Wear of stainless steel fan transmission parts is a common equipment problem, including exhaust fan bearing position, bearing room wear, blower shaft bearing position wear and so on. In view of the above failures of stainless steel fans, traditional repair methods include surfacing, thermal spraying, brush brushing, etc., but there are certain disadvantages: the thermal stress generated by the high temperature of repair welding cannot be, which is likely to cause material damage and cause Parts are bent or broken; while brush plating is limited by the thickness of the coating, it is easy to peel off, and the above two methods use metal to repair the metal, which cannot change the "hard-to-hard" cooperation relationship. Under the combined effect of various forces, This will cause the abrasion of the rubber-covered roller to wear again.

ontemporary Western  uses polymer composite repair methods for the above problems, and the most commonly used is the American Fu Shilan technology system, which has the comprehensive properties such as superb adhesion, excellent compressive strength, etc. Can be dismantled and machined. It has neither the effect of repair welding thermal stress nor the limitation of repair thickness. At the same time, the metal material of the product does not have the concession, which can absorb the shock and vibration of the equipment and avoid the possibility of re-wearing. It is gradually replacing traditional methods.
