In order to avoid any doubt in the operation of vacuum pump, this paper introduces how to correct the vacuum pump: the corrosion shape of vacuum pump can be divided into total (uniform) corrosion and partial corrosion. The former is more uniform in all the surface of vacuum pump, while the latter only occurs in some parts, such as pitting corrosion, crevice corrosion, intergranular corrosion, stress corrosion, etc.
It is one of the effective anti-corrosion methods to select polymer composite materials to carry out surface organic coating anti-corrosion of vacuum pump. It has outstanding chemical resistance function, excellent mechanical function and bonding function. Compared with the traditional welding repair of pressure vessel, it has the characteristics of simple construction, low cost, safety function and good correction function.
Scaling and cleaning of vacuum pump in the application process, due to the technical water, calcium and magnesium hardness, pH value, conductivity, total alkalinity, temperature and other factors, scaling appearance will occur, and then constitute the following damage: 1. Increase the consumption of chemicals
