- W3100702321 abstract "The article considers the issues of increasing the efficiency of cryogenic vacuum pumps to create a deep vacuum used in production processes during chemical and physical experiments. It is noted that the use of zeolites as a sorbent material, in comparison with activated carbons, provides a more efficient absorption of hydrogen and helium. It is proposed to increase the heat sink using compositions of zeolite and metal powders with high thermal conductivity, pressed onto the surface of the tubes. It is shown that the best results are achieved when using the composition of zeolite - copper powder. It is proposed to use the process of elastostatic pressing for the manufacture of coaxial-cylindrical samples. The original design of the pump with coaxial-cylindrical samples with the pressing of the sorbent composite layer is presented. The results of practical tests of the pump are presented. The prospects of using the developed adsorption cryogenic-vacuum pumps with sorbent elements based on zeolite and copper powders are considered. This research work was supported by the Academic Excellence Project 5–100 proposed by Peter the Great St. Petersburg Polytechnic University." @default.
