Increasing energy efficiency and enabling the process of vacuum mode stabilization during the operation of milking equipment

Abstract

A scientific hypothesis has been put forward, according to which an increase in the efficiency of using a vacuum system of milking equipment with an upper milk line with mechanical pulsators can be achieved by predicting its residual resource. As well as with the subsequent planning of maintenance and the identification of patterns and dependences characterizing these processes. As a result of experimental studies of changes in the technical and technological parameters of the vacuum system of milking equipment with an upper milk line with mechanical pulsators, the theoretical dependences obtained with their correlation coefficient r=0.971–0.972 were empirically confirmed. Namely, the magnitude of the working vacuum, the pulsation rate, the ratio of pulsations, and the tension force of the nipple rubber, depending on the time of operation. It was established that after 175 hours of operation of the milking stationary installation, the value of the working vacuum decreased by 4 %, the pulsation frequency – 14 %, the ratio of pulsations – 16 %, and the tension force of nipple rubber – 21 %. On the basis of the obtained dependences included in the procedure for forecasting the resource of the vacuum system of milk-milking equipment with an upper milk line with mechanical pulsators, the software package «Alt viewer 1.0» was developed. It is designed to display and automatically process the measurement results of the technical and technological parameters of milking equipment using the designed Tester of milking machines, v.2.0. The software performs the following main functions: reading the measurement results from the memory card, decoding them, displaying them in tabular and graphical forms. As well as the calculation of the parameters of pulsations and the formation of a report, forecasting the resource of the nodes of the vacuum system. The program also provides for the storage of information on the calibration coefficients of pressure sensors, air flow meter, as well as the frequency of polling sensors when measuring pulsations and fluctuations of the working vacuum
