Abstract

The invention relates to a vacuum obtaining apparatus, namely a dry type screw rods vavuum pump that designs two screw rods into hollow and employs the heat pipe internal cooling method. In the heat pipe internal cooling dry type screw rods vacuum pump provided by the invention, the screw rods are made into hollow; the internal of the screw rods are cooling chambers, which is convenient for cooling the screw rods, taking away the heat generated by the screw rods, therefore the surface temperature of the screw rods is reduced, the problem of medium solidification carbon formation generated in the process of pumping the medium by the screw pump is solved, and service life of the screw rods are greatly improved.

Description

technical field

[0001] The invention relates to vacuum obtaining equipment, which is a dry-type screw vacuum pump in which two screw rods are made hollow and cooled by heat pipes. Background technique

[0002] The screw vacuum pump has been proved to be a dry vacuum pump with excellent performance. It has the advantages of low ultimate pressure, simple vacuum system, no medium in the working chamber, clean vacuum, wide application range, and environmental protection. It is more and more used in All walks of life, replacing traditional water ring vacuum pumps and oil-sealed vacuum pumps. Due to the high temperature in the working chamber of the screw vacuum pumps currently on the market, it is easy to produce solidified carbon deposits in the medium, which seriously affects the service life of the vacuum pump, and the solidified carbon deposits in the working chamber need to be cleaned regularly. Contents of the invention

[0003] In order to solve the above-mentioned prob...
