How to solve the rusting of the blower?
Release time:
2022-03-31
When rotary blowers are used for a long time, various problems may arise, such as rust inside the machine. We can use small electric motors and pneumatic tools, such as angle grinders and polishers, to utilize their impact and sanding effects to remove rust and dirt. Sandblasting is a more thorough method of rust removal, capable of completely eliminating impurities and rust layers adhered to the metal surface. The surface treated by sandblasting provides good mechanical adhesion for coatings. Sandblasting methods include: dry sandblasting, warm sandblasting, closed dust-free sandblasting, throwing force method, and high-pressure water sandblasting. Chemical rust removal: This method is particularly suitable for processing workpieces with complex shapes and structures. It is important to note that the quality of the substrate itself and the construction requirements may vary. The metal is placed in an acid solution for washing, allowing the acid solution to chemically react with the metal surface oxides to achieve rust removal. It is recommended to use diesel for rust removal! The specific operation steps are as follows: If the Roots blower impeller is rusty, you can remove the blower outlet silencer, block the blower outlet, and pour kerosene from the inlet, which can soak about half of the blower chamber. After soaking in kerosene for a few hours, try to rotate it (you can use a flat pry bar inserted into the impeller gap to assist in rotation, being careful not to damage the impeller). If it can rotate, you can let the other impeller soak in kerosene for a few more hours, and you can wait until the next day to start running. Manual rust removal: Use tools such as diamond sandpaper, scrapers, hammers, and wire brushes to manually chisel and brush off the rust layer, and use cotton sandpaper to wipe away the rust dust before painting.
