Vacuum system and high vacuum system

There are many kinds of vacuum application equipment, but no matter what kind of vacuum application equipment, there is a suction system to exclude the gas in the vacuum container, so as to obtain the required vacuum conditions in the vacuum container. For example, a container for vacuum treatment is connected with a vacuum pump by pipes and valves. When the vacuum pump evacuates the container, there must be a vacuum measuring device on the container, which constitutes a simple vacuum pumping system.

Simple vacuum system can only obtain the vacuum degree in the low vacuum range in the pumped container. When it is necessary to obtain the vacuum degree in the high vacuum range, a high vacuum pump is usually connected in series in the vacuum system. When a high vacuum pump is connected in series, valves are usually added to the inlet and outlet of the high vacuum pump, so that the high vacuum pump can keep the vacuum alone. If the series high vacuum pump is an oil diffusion pump, in order to prevent a large amount of oil vapor from flowing back into the pumped container, a trap - water cooling baffle is usually added at the entrance of the oil diffusion pump. According to the requirements, dust collector, vacuum relay gauge head, vacuum soft connection pipeline, vacuum pump inlet vent valve and so on can also be added to the pipeline, thus constituting a relatively perfect high vacuum system.
