Results of experimental research milking machine with adaptive pneumatic and electromagnetic pulsators

Abstract

In the article the results of experimental studies milking machine with an adaptive pnevmoelektromahnitnym pulsators. The results of the study of the effect structurally technological parameters of the length of pumping air from the vacuum chamber alternating pressure system and compared to experimental results with theoretical data. It is established that the duration t pumping and filling air chambers variable vacuum pressure system "glass-milking pulsator" increases with decreasing diameter overflow hole dper pulsator and with increasing vacuum pressure Pi. Analysis of the dependencies enables recommend rational parameters pnevmoelektromahnitnoho pulsator provided shockless and ensuring the smooth opening and closing diykovoyi rubber milking cups with vacuum pressure Pi = 48 kPa and variable volume chamber pressure vakuummmetrychnoho of "glass-milking pulsator" V = 10 -4 m3. For the duration t of pumping air chambers variable vacuum pressure set in the range of 0.16 to 0.17 seconds, the diameter of the overflow hole pulsator should be within dper = 3-3,2 mm. For the duration t filling air chambers variable vacuum pressure set in the range of 0.155 to 0.165 with a diameter overflow hole pulsator should be within dper = 3,2-3,4 mm.
