DYNAMICS OF THE VACUUMMETRIC PRESSURE OF THE DAIRY CHAMBER OF THE COLLECTOR OF MILKING MACHINE

Abstract

Presented in the market serial collectors of milking machines of known manufacturers differ in design parameters and operating modes. This indicates the search for a rational design of the collector, which must fully meet the zoo-technical requirements for machine milking cows. The performed assessment proves the presence of undisclosed issues regarding the level of vacuum pressure in the milk chamber of the milk manifold collector and its effect on the stability of the regime characteristics. In particular, this concerns the effect of pressure fluctuations on the quality of milk and the health of cow dander. Scientists have a significant impact of unstable vacuum pressure on the desired performance characteristics of the milking machine and the preservation of the health of cows. The time-varying intensity of the flow of milk causes the dispersion of fatty balls and the foaming of milk in a flexible milk line, which worsens its technological properties. The influence of structural and geometric parameters of the collector of the milking machine on increasing the efficiency of the technological process of milk transport is proved. The insignificant influence of milk yield intensity on the level of vacuum-pressure in the milk chamber of the collector within the fixed diameter of the flexible milk pipeline is established. The mathematical model of the change of vacuum pressure in the milk chamber of the collector depending on the diameter of the milk pipe at a given intensity of milk yield is obtained. The influence of the fixed diameter of the throttle on the change in the level of vacuum pressure in the milk chamber of the collector in the compression cycle in accordance with the diameter of the milk hose and the intensity of milk yield are simulated. The concept of the permissible permitted condition for the release of the milk chamber of the collector from milk is introduced, depending on the design and technological features of the proposed two-section collector and the operating modes of the milking machine.
