Lubrication and leaking stoppage method for dynamic seal of high-vacuum equipment

Abstract

The invention provides a lubrication and leaking stoppage method for a dynamic seal of high-vacuum equipment. The lubrication and leaking stoppage method includes steps that A, a liquid storage tank is additionally mounted at the upper end of the dynamic seal, and the lower end of the liquid storage tank is connected with the high-vacuum equipment; and B, liquid lubricants and solid lubricating leaking stoppage materials are added into the liquid storage tank to realize leaking stoppage and sealing. Liquid materials and the solid materials are used for lubrication and leaking stoppage, so that the lubrication condition of the dynamic seal of the high-vacuum equipment can be effectively improved, gas can be stopped against leaking slightly under the conditions that the dynamic seal and a movable part are worn and the movable part is slightly damaged, and the lubrication and leaking stoppage method is remarkable in effect and has high popularization and application values.

Description

technical field [0001] The invention relates to a plugging method, in particular to a method for lubricating and plugging dynamic seals of high-vacuum equipment. Background technique [0002] The level of leakage rate of high vacuum equipment directly affects the quality of products. There are micro-leakages in the equipment, the time to obtain high vacuum is doubled, and even the production requirements cannot be met, which not only increases energy consumption, but also directly affects production efficiency. [0003] At present, the dynamic seal of high vacuum equipment generally consists of several skeleton oil seals and movable parts. If it is used in high-vacuum equipment for welding and smelting, due to the harsh environment and large dust, it is easy to cause wear and tear on the dynamic seal and moving parts, and sometimes cause slight damage to the moving parts. At this time, there will be micro-leakage at the dynamic seal, which will cause The oxygen content of ...

Problems solved by technology

If it is used in high-vacuum equipment for welding and smelting, due to the harsh environment and large dust, it is easy to cause wear and tear on the dynamic seal and moving parts, and sometimes cause slight damage to the moving parts. At this time, there will be micro-leakage at the dynamic seal, which will cause The oxygen content of the product is too high and the welding is oxidized. In this case, only the dynamic seal or movable parts should be replaced.

However, sometimes there are micro-leaks that cannot be detected by a leak detector, and some dynamic seals are very difficult to replace and take a long time to replace, and the movable parts are expensive, and some are even as high as hundreds of thousands
