1) According to the different requirements of corrosion resistance and cavitation erosion degree of each flow passage component, different process measures are adopted on the substrate made of cast iron, cast steel or carbon steel, which greatly improves the acid resistance, alkali resistance and cavitation resistance, and prolongs the service life. The lining layer of flow passage parts can work reliably within the specified maintenance period under the condition of vacuum degree 3kpa and water and steam scouring. The maintenance cycle is 0.5 ~ 2 years according to the different working conditions such as corrosive medium, temperature and pump speed. Compared with stainless steel, the anticorrosion cost can be reduced by 1 ~ 5 times under the same working conditions and service life.
2) Because the matrix of the vacuum pump parts will not be damaged, when the corrosion-resistant lining fails, it can be repaired repeatedly simply, economically and effectively.
3) It can be used in all water ring vacuum pumps with flat distributor structure, with low cost, long service life and relatively simple manufacturing process. It is suitable for pumping corrosive gases without solid substances in chemical, metallurgical, environmental protection, papermaking, pharmaceutical and other industries.
