Roots blower in the process of using the “injured” situation, I Roots blower on the “injury” to bring you to understand the solution.
1. For minor abrasions, the abrasions can be smoothed with an oil stone. If the chassis or wall panels are scuffed with large area, deeper layer, or corrosion is more serious and the inner hole of the chassis is deformed, the chassis can be corrected by machining. If the processing has a large impact on the size, if necessary, can be coated, sprayed and other methods to be repaired.
2. For the eyelet defects occurring in the Roots blower casing, the outer surface of the wall panel and the fixed bonding surface, you can use epoxy resin special filler goods putty to fill. For some small holes on the working surface, you can use plugs with threads for plugging, or use nickel-iron welding rod for welding.
3. For the cracks of the Roots blower casing, it is also possible to make up the welding without affecting the use of the Roots blower. Mending welding has hot welding and cold welding two methods, hot welding is to preheat the parts to 650-700 ℃, welding operation at this temperature, cold welding without preheating. Due to the cold welding method is economical, easy to do, the repair of most of the use of this welding method.
