Abstract

In this paper, the mathematical model of the gravitational pressure regulator vacuumtype damper membrane. Powered solution of differential equations to simulate the movement of the valve, depending on the amplitude and frequency fluctuations of the vacuum pressure, weight load, the diameter of the valve, damper and membrane diffuser diameter hole in the cap of the regulator. These features and schedule amplitude and frequency of vibrations of vacuum pressure and simulation results of displacement vacuum pressure regulator valve milking installation. The simulation results of the amplitude fluctuations in vacuum pressure showed that reduction of duration τ pumping air from chambers of variable pressure vacuum milking machines leads to increased frequency fluktatsiy pressure. With increasing diameter ddf diffuser reduces attenuation coefficient 2n2 fluctuations. However, the diameter of the cone ddf = 1,7-1,9 mm displacement of the valve is maximum and is 24-25 mm for the attenuation coefficient 2n2 = 0,667-0,427. For all other values of the diameter of the cone and move the valve damping coefficient decreases.
