Abstract
The utility model relates to an experimental device capable of realizing stable high vacuum degree. According to the experimental device, by utilizing a liquid nitrogen capacity measurement control device, liquid nitrogen in a liquid nitrogen tank enters a liquid nitrogen condenser and a liquid nitrogen condensation pump through a leather hose, and a vacuum diffusion pump is started to guarantee the stable high vacuum degree in a vacuum chamber, thus saving liquid nitrogen resources. The experimental device is characterized in that the liquid nitrogen tank is placed on a shear type hydraulic stretching and lifting platform, and the liquid nitrogen can uniformly enter the leather hose in a way that the shear type hydraulic stretching and lifting platform moves up and down; a vacuum gauge is equipped above the vacuum chamber and is used for reading the vacuum degree of the vacuum chamber.
Description
Technical field:
The utility model relates to a kind of experimental provision of realizing stablizing condition of high vacuum degree, relate in particular to a kind of vacuum chamber and can realize stablizing condition of high vacuum degree, can realize simultaneously effective utilization of liquid nitrogen, reduce energy resource consumption, keep making and the research and development fields of the experimental provision of equipment surrounding environment cleaning.
Background technology:
In existing technology, known technology is that the use of vacuum friction wear testing machine liquid nitrogen is by manually pouring into.In friction process, due to artificial the pouring into of liquid nitrogen, can not guarantee at the uniform velocity pouring into of liquid nitrogen on the one hand, cause the interior vacuum tightness of vacuum chamber stable not, the liquid nitrogen that flows out when manually pouring on the other hand is with the environmental pollution around experimental facilities, and the waste resource.
Summary of the invention:
The purpose of this utility model, be exactly for the existing deficiency of prior art, a kind of experimental provision of realizing stablizing condition of high vacuum degree that has is provided, can realize condition of high vacuum degree stable in vacuum chamber, can realize simultaneously effective utilization of liquid nitrogen, reduce energy resource consumption, keep the experimental provision of equipment surrounding environment cleaning.Experimental provision is simple, easy to operate, with low cost, has very strong practical value and promotional value.
The technical scheme that the utility model technical solution problem adopts is: critical piece comprises vacuum chamber, liquid nitrogen cubic content measurement control device, liquid nitrogen condensation device, liquid nitrogen condensation pump, liquid nitrogen container, scissors hydraulically extensible lifting table, vacuum meter, leather hose etc.Be connected with leather hose between liquid nitrogen condensation device and liquid nitrogen condensation pump and liquid nitrogen container; Liquid nitrogen cubic content measurement control device is controlled the horizontal level of liquid nitrogen in the interior liquid nitrogen condensation device of vacuum chamber and liquid nitrogen condensation pump; Liquid nitrogen container is positioned over above scissors hydraulically extensible lifting table, can move up and down, and liquid nitrogen is evenly flowed into; Vacuum chamber top adapted vacuum meter is used for reading vacuum tightness in vacuum chamber.
The beneficial effects of the utility model are: realize the stable of vacuum tightness in the vacuum chamber, saved liquid nitrogen, and cleaning experimental facilities surrounding environment, experimental data is more reliable.In addition, experimentation is simple to operate, simple, practicability and effectiveness, with low cost reasonable in design.
Description of drawings:
Fig. 1 is the front view of the structural representation of the utility model embodiment
In figure, 1 is vacuum chamber, and 2 is vacuum meter, and 3 is the liquid nitrogen condensation device, and 4 is vacuum diffusion pump, and 5 is liquid nitrogen cubic content measurement controller, and 6 is leather hose, and 7 is liquid nitrogen container, and 8 is scissors hydraulically extensible lifting table, and 9 is the liquid nitrogen condensation pump.
Embodiment: for more clearly demonstrating the technical characterstic of the technical program, also by reference to the accompanying drawings this programme is set forth below by an embodiment.
In Fig. 1, liquid nitrogen container 7 is positioned over scissors hydraulically extensible lifting table 8 tops, guarantees the liquid nitrogen of required abundance in experimentation.Liquid nitrogen flows in the interior liquid nitrogen condensation device 3 of vacuum chamber 1 and liquid nitrogen condensation pump 9 by leather hose 6, and the amount of liquid nitrogen starts vacuum diffusion pump 4 by liquid nitrogen cubic content measurement control device 5, guarantees the vacustat in vacuum chamber.Vacuum tightness is represented by the reading of vacuum meter 2.Scissors hydraulically extensible lifting table 8 moves up and down to guarantee the even inflow of liquid nitrogen.
