Embodiment Construction

[0013] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings:

[0014] Depend on figure 1 It can be seen that the combined unit involved in the present invention includes: a vacuum degree measuring device 2, an auxiliary extraction suction chamber 3, a main extraction suction chamber 4, and also includes a degassing unit 5 and a vacuum pump 6; 12 is connected with the cavity interface 1 that needs to be vacuumed. During specific implementation, each independent unit can be installed on the same frame, and can also be assembled by pipelines. If each independent unit is installed on the same frame, the vacuum pump 6 can be selected as a small vacuum pump to provide energy for each independent unit. Power supply 7 can choose to use dry battery pack or accumulator pack.

[0015] The method for realizing the high vacuum degree in the cavity involved in the present invention is realized by the above-mentioned combination...

Abstract

This invention characterizes that cavity for vacuum-pumping contacts with activated suction materials in sealing then the remained gas in the cavity contacts with Zr like activated suction materials to increase the vacuity to above 10 to the power -3 pa. The combined set includes cavuity measurement device, main pumping induction chamber, secondary pumping induction chamber, releasing unit and vacuum pump each independent unit connects with interfaces of cavity for vacuum pumping by valves with the advantages of having Na, k, p, Ba and their alloys suction materials as the main pumping material and Z like suction material as the secondary pumping materials.

Description

Technical field: [0001] The invention relates to a method for realizing high-vacuum rapid extraction in a cavity of a container to be vacuumed and a combined unit thereof. Background technique: [0002] At present, in order to achieve a high vacuum degree in the chamber that needs to be vacuumed, vacuum pumps, Roots pumps, etc. are generally used as the front-end units for low vacuum degrees, and diffusion pumps, molecular pumps, titanium lift pumps, etc. are used as high vacuum degree units. And the final unit of ultra-high vacuum degree, this method of obtaining high vacuum degree generally has a relatively large system, which is suitable for mass production and long-term fixed processing mode, and requires sufficient power for protection. [0003] Sodium, potassium, phosphorus, barium, etc. and their alloy getters and zirconium getters can adsorb active gases due to their inherent physical properties. It is well known that sodium, potassium, phosphorus, barium, etc. and ...
