“…Разработанные до настоящего времени математические модели процесса откачки газа высоковакуумными механическими насосами (ВМН) не позволяли с достаточной точностью рассчитывать откачные характеристики и параметры разных типов молекулярных вакуумных насосов (МВН) [1][2][3][4][5][6][7]. Предлагаемая универсальная математическая модель процесса откачки газа впервые позволяет описать процесс откачки газа как дисковым, так и цилиндрическим МВН при разных режимах течения газа.…”

For the first time, the universal mathematical model describing the working process of de-gassing by a molecular vacuum pump has been developed in a wide range of pumping parameters under different gas flow regimes, which allows calculating the channel parameters of disk and cylindrical molecular vacuum pumps. The adequacy of developed mathematical model is verified by comparison with the experimental data -the maximum calculating error doesn't exceed 20% Mathematical model, vacuum pump, molecular vacuum pump, optimization, pumping speed, flow part

High-vacuum mechanical pumps are widely used in various fields of science and technology for research and industrial applications. Modern high-vacuum mechanical pumps include molecular vacuum pumps, turbomolecular vacuum pumps and hybrid turbomolecular vacuum pumps, i.e., designs that represent a turbomolecular vacuum pump with one or more additional molecular stages. There are also a number of experimental and theoretical developments that propose combinations of different types of high-vacuum pumps in which, as a rule, on the suction side the main pumping is carried out by an axial turbomolecular stage. These schemes belong to the class of modern high-vacuum mechanical pumps. The paper examines the designs and analyzes scientific studies of modern high-vacuum mechanical pumps. Relying on this overview, we found the unsolved problems of designing and mathematical modeling of high-vacuum mechanical pumps working processes, which could give further prospects for vacuum technology development
