While designing the vacuum system of a milking machine it is necessary to study the influence of structural element parameters on the level of vacuum metric pressure. In particular, a long-lasting action of pressure, different from a standard one, affects the operating performance of a milking machine, and it can result in negative consequences on cows’ wellbeing. That is why a structural and a technological scheme of a vacuum system must provide fast pressure stabilization. It has been determined that the operating performance of a vacuum system of a milking machine has a non-stationary nature. It has been stipulated by combining structural elements with wide range of pressure into one system. A temporary access to pressure of higher potential has a significant effect on the pressure level in a vacuum system. The method of classic calculations of a vacuum system does not take this peculiarity into consideration. The determination of duration of both balanced and stabilizing periods is of great importance for efficient machine milking. It has been determined that a higher volume of a vacuum net is characterized by less pressure losses. The study of the effects of the parameters of a vacuum system on the level of a balanced pressure has been conducted. It has been scientifically concluded that a vacuum net permeability effects the duration of a balanced state of a vacuum system. The mathematic model of a balanced pressure dynamics of a vacuum system has been received. It has been proved that a balanced pressure of a vacuum system depends on both the constructional and the technological parameters of its structural elements. The mathematic model of the dynamics of pressure of the vacuum system stabilization has been determined. The nature of a balanced pressure effects on the duration of a stabilizing period has been revealed. A rational balance between the parameters of the vacuum system elements has been determined.
