The purpose of the disc-type welded vacuum bellows bellows
1. The pressure is based on the actual working pressure of the hose, and then check the nominal diameter and pressure gauge of the bellows to determine whether to use the stainless steel mesh sleeve type.
2. The size of the nominal diameter of the hose, select the joint type (mainly flange connection, thread connection, quick joint connection), size, and hose length.
3. The state is based on the state of the hose when it is used, referring to the correct use and installation method of the metal hose and the optimal length of the hose during settlement compensation. The length calculation of the hose in various motion states, the minimum bending times and the minimum bending radius of the hose and other factors, the correct selection of the length of the hose and the correct installation of the parameters.
4. The working temperature and range of the medium in the temperature hose; the ambient temperature when the hose is working. When the temperature is high, the pressure after temperature correction must be determined according to the temperature correction coefficient of the working pressure of the metal bellows at high temperature to determine the correct pressure level.
5. The chemical properties of the medium transported in the medium hose determine the material of each part of the hose according to the corrosion resistance parameter table of the hose material.
6. Vacuum hoses are mainly used in the production of monocrystalline silicon to achieve negative vacuum.
