ANALYSIS OF THE PHASE PORTRAIT OF MILKING MACHINE PULSATIONS
The article is devoted to the process of diagnosing the technical condition of milking machines by using modern diagnostic devices and the subsequent analysis of obtained data. The algorithm for analyzing teat cups pulsations by frequency and phase portrait is described by which is meant the duration of individual phases in the working cycle of the milking machine. A modern approach to dividing the working cycle of a milking machine into separate strokes and phases is considered. The influence of the duration of individual phases on the physiological nature of the process of machine milking of cows has been analyzed. The data on the optimal intervals for varying the duration of the phases in the working cycle of the milking machine are systematized. The analysis of the influence of changes in the duration of individual phases on the rate of milk flow and the state of health of the animal after milking has been performed. The influence of degradation of elastic properties of liner during its operation on changes in the phase portrait of the milking machine is described. The importance of ensuring the same operating mode for all milking machines on a farm is noted.
