Common fault maintenance methods for vacuum pump repair are as follows:
1. Wear of pump shaft bearing position: Wear of vacuum pump transmission parts is a common problem, including wear of bearing positions, bearing seats, bearing chambers, keyways and threads.
Maintenance skills: Contemporary Western countries mostly use polymer composite material repair methods, and the US Migahua technology system is more commonly used, which has strong adhesion and high compressive strength. This method can be repaired without disassembly and machining. There is no effect of repair welding thermal stress, and the repair thickness is not limited. At the same time, the products concession can absorb the shock and vibration of the equipment, avoid re-wearing, and greatly extend the service life of equipment components, saving a lot of downtime for enterprises, and creating huge Economic value.
2. Corrosion: The corrosion of vacuum pumps can be divided into two categories: general corrosion and local corrosion. The former occurs more uniformly on the entire surface of the vacuum pump, while the latter only occurs locally, such as pitting corrosion, crevice corrosion, intergranular corrosion, stress corrosion, etc. .
Vacuum pump repair and maintenance skills: the use of polymer composite materials to implement organic coating on the surface of the vacuum pump for anti-corrosion. It has very good chemical resistance and excellent mechanical properties and bonding properties. Compared with traditional pressure vessel welding repairs, it has simple construction, Features of low cost, safety performance and good repair effect.
3. Shell cracks: due to casting, processing defects, internal stress and overload operation, vacuum pumps often cause cracks or fractures in parts.
Vacuum pump repair and maintenance skills: The conventional repair method is welding, but some parts are made of cast iron, aluminum alloy, and titanium alloy, which is difficult to weld. There are also some dangerous occasions that are prone to explosion, and it is even more difficult to use welding repair methods. MEGAWA technology is a kind of "cold welding" technology, which can avoid thermal stress and deformation. At the same time, the material has good adhesion, compression resistance, corrosion resistance and other properties, which can meet the requirements of various equipment components to the greatest extent. Cost investment effectively guarantees production, safety, convenience and reliability.
