There are many kinds of vacuum application equipment, but the vacuum application equipment has a set of gas pumping system used to discharge the vacuum container, so as to obtain the required vacuum conditions in the vacuum container. For example, a container for vacuum treatment is connected to a vacuum pump through a pipe and a valve. The container must have a vacuum measuring device. When the vacuum pump evacuates the container, it constitutes the simplest vacuum pump system.

The simplest vacuum system can only obtain a vacuum level in the low vacuum range of the pumping container. When it is necessary to obtain a degree of vacuum in the high vacuum range, a high vacuum pump is usually connected in series in the vacuum system. Usually, valves are added to the inlet and outlet of the high vacuum pump. When the high vacuum pump is connected in series, the high vacuum pump can maintain the vacuum independently. In order to prevent a large amount of oil vapor from flowing back into the pumping container, if the high vacuum pump in series is an oil diffusion pump, a trap is usually added at the inlet of the oil diffusion pump-Water-cooled baffle. According to needs, you can also add a vacuum relay header, dust collector, vacuum soft connection pipeline, vacuum pump inlet vent valve, etc., to form a complete high vacuum system.

In any vacuum system consisting of more than two vacuum pumps in series, usually called the front pump of the previous high vacuum pump(or front pump)It is a low vacuum pump, and the most important pump is the highest vacuum pump called the main pump of the vacuum system. The ultimate vacuum degree and working vacuum degree in the pumped container are determined by the main pump. The pipeline from the outlet of the pumped container to the inlet of the main pump is called the high vacuum pipeline, and the valve at the inlet of the main pump is called the main valve. Usually, the backing pump is also used as a vacuum pump. The pipeline from the pumped container to the pre-pumping pump is called the pre-vacuum pipeline, and the valve on the pipeline is called the pre-vacuum pipeline valve. The pipeline from the main pump outlet to the previous pump inlet is called the previous pipeline, the valve on the pipeline is called the previous pipeline valve, and the soft connection pipeline is set to isolate the vibration of the previous pump.

Generally speaking, a perfect vacuum system consists of the following parts:1,.Pumping equipment: e.g. various vacuum pumps2Vacuum valve;3Connecting pipe;4Vacuum measuring devices: such as vacuum pressure gauges and various instruments;5Other components: for example, trap, dust collector, vacuum relay, gas tank, etc.

So, what exactly is a vacuum system? In a word, it is used to obtain a specific vacuum degree of the pumping system. The basic content of the vacuum system design is: according to the vacuum requirements of the pumping container, select the appropriate vacuum system design scheme, calculate the selection and configuration of the pump; determine the catheter, valve, trap, vacuum measuring element, and reasonable configuration. Finally, draw the assembly drawing and parts drawing of the vacuum system.
