Abstract
The article describes the results of theoretical calculations of the loads acting on the radial surface of the blade of a plate-type vacuum pump used in milking systems. On the basis of experimental studies of Fluoroplast-4, its use for sealing highly loaded movable seals in vacuum systems is substantiated. The results of experimental studies on the dependence of the actual contact area and specific pressure on the load of 0-100 N are presented. An analysis of the data showed that in the range of loads of 0 to 10 N, the dependence is almost linear. In the range of 20 to 100 N, the specific pressure reaches a limiting value and ranges from 47.3 to 57.8 MPa, i.e. it stabilizes. These data indicate that for sealing the most loaded and critical movable seals in milking vacuum systems, it is possible to use Fluoroplast-4.
