Abstract

The article analyzes the results of studies of the effect of liner on the cow's udder during milking. It is analyzed that the determination of the effect of the critical pressure of the liner on the cow teat only in the compression stroke does not sufficiently describe the dynamics of the process of compression the cow teat of liner. The necessity to study the displacement of the walls of the liner during compression is substantiated. A regression equation to characterize the dependence of the vacuum pressure closing value of the liner Рзм of the adaptive milking glass on the vacuum pressure Рі and the diameter of the bypass hole dпер is presented. The significance of the regression equation coefficients was checked. Increasing the vacuum pressure from 36 to 48 kPa and increasing the diameters of the bypass opening increases the pressure of closing the liner within sufficiently large limits. At vacuum pressure at 36 kPa for all values of the diameters of the bypass hole, there is a stabilization of the tire pressure of the liner.
