Abstract: The study of existing types of profiles of screw bodies of vacuum pumps, determining the advantages and disadvantages of various types of profiles. Studying the energy efficiency problems of screw vacuum pumps, the influence of the geometry of the slots in the working cavity on the backflow and useful volume. As a result, a program was created for obtaining profile geometry. [ABSTRACT FROM AUTHOR]
