Vacuum electron beam welding is a high-energy electron beam heating metal welding technology. Its basic principle is to use a high-pressure electron gun to emit high-speed electrons into the weld area, and then focus the electric field to form an electron beam, converting the energy of the electron beam into thermal energy to quickly heat and melt the welding material. Electron beam welding at vacuum can obtain high-quality welding joints. Therefore, it is widely used in fields such as aviation, aerospace, and nuclear industry. Like many vacuum processes, the use of vacuum electron beam welding also requires the installation of a filter to protect the vacuum pump.
During the process of vacuum electron beam welding, the high-pressure electron gun produces metal vapor and oxides during operation. These impurities sucked will contaminate the vacuum pump oil, causing turbidity, emulsification, and other phenomena. They will also damage the impeller or seal of the vacuum pump chamber, affecting the safe operation of the vacuum pump.
If these metal vapors and oxides are not removed in a timely manner, it will affect the effectiveness of electron beam welding. Therefore, in order to maintain the stability of vacuum electron beam welding, it is necessary to remove impurities. This also reflects the necessity of vacuum pump filters.
LVGE, a vacuum pump filter manufacturer with over 10 years of industry experience, gradually explores more vacuum application fields. We are dedicated to providing suitable vacuum pump filtration solutions for more fields and serving more customers. Our goal is to become a globally trusted brand of vacuum pump filters.
