[0028] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following further describes the present invention in detail with reference to embodiments and drawings:
[0029] For the convenience of description, in the present invention, the acquisition of the vacuum of the vacuum device and the recovery of the atmosphere are briefly described.
[0030] The vacuum device is welded and assembled with structural metal carbon steel, stainless steel, etc. In order to obtain the required vacuum, it is necessary to install an extraction system on the vacuum device. Generally, the extraction system is divided into two parts: rough extraction system and fine extraction system. The rough pumping system generally consists of a mechanical pump with a high pumping speed, a roots pump, a backing valve controlled by a cylinder and a solenoid valve, and a fine pumping system includes one or more sets of high vacuum pumps and a backing pump set of ...
