Recently, a small partner asked Xiaobian spin-chip vacuum pump in the small lid swollen swollen What to do? What good repair methods? Xiaobian advice related technical staff, for everyone a brief introduction rotary vane vacuum pump cover repair knowledge, hope Can help to everyone.    Damage is not serious small cap, you can use the No. 3 emery cloth to wipe the surface rust, and then coated with a thin layer of red lead, with the impeller with it, hand rotating the impeller several laps, and then observe the cone surface. A small cover was rubbed off the part of red lead, indicating that the higher part of the rasp file can be flat. Impeller with the cone on the surface is rubbed traces of Histamine, is also a higher part, available scraper scraping away. After the initial repair, re-painted red lead, a small lid with the impeller and rotate, repeat the above repair procedures. This repeated several times until most of the small cap conical mating surface with red lead, most of the impeller conical mating surface evenly coated with red lead, indicating that the two with the surface of the basic smooth, with the basic close. At this point you can grind the two mating surfaces. First with rough scrub tone coated on the small cap conical surface, and then with the impeller with grinding. After several times, with the contact surface up to 80%, and then grinding with a fine grinding sanding time, the last wipe with a cotton matte, and the surface coated with a layer of oil.    If the damage is more serious, that is to say the surface of the cone is not smooth with prominent phenomenon, in order to speed up the repair speed, you can first go to the lathe on the floor, and then repaired in accordance with the above method.    Small cover repair, the wall thickness is bound to reduce, you can use metal spray coating layer of metal. In addition, the small cap of the cone also gradually smaller, on the contrary, the impeller space gradually expanded, so after assembly inevitably does not meet the original assembly position, the impeller will meet the end face of large diameter at one end of the small lid large cap, The end face of the small diameter will hit the impeller shaft hole end face. MC Oil-Filled Cast Nylon Liners MC oil-filled cast nylon liners are a type of liner used to protect the interior walls of silos. They are made from a type of nylon material that is cast with oil to provide added lubrication and impact resistance. These liners are designed to withstand high levels of abrasion and impact, making them ideal for use in silos that store abrasive materials. The oil-filled design also helps to reduce friction and wear, extending the lifespan of the liner. MC oil-filled cast nylon liners are a cost-effective solution for protecting the contents of a silo, while also providing excellent insulation and protecting stored materials from contamination.
