Opis:
The article analyzes the results of experimental studies of duration of air pumping out from chambers of the variable vacuum-gauge pressure in the "teat cup - pulsator"system. The study of impact of structurally-technological parameters of milking units on the process of milk ejection and time characteristics of the operating mode was analyzed. The methods of conducting experimental studies of transitive time characteristics of pulsator operating modes based on differentiated study of transitive processes by high-frequency scanning of vacuum-gauge pressure changes while pumping air out from the "teat cup-pulsator" system are given. Results of the study of impact of vacuum pressure and the overflow hole diameter on the duration of air pumping out from chambers of the variable vacuum-gauge pressure system are provided. Results of experimental data are compared with theoretical ones. The analysis of results of experimental studies showed that the pulsator overflow hole diameter has the greatest effect on the duration of air pumping. By reducing the diameter, the duration of air pumping increases nonlinearly. Due to results of comparison of theoretical and experimental studies it was found the deviation of experimental data from the theoretical modeling of the duration of air pumping out from chambers of the variable vacuum-gauge pressure in the"teat cup - pulsator"system. The coefficient of coordination of theoretical dependencies on experimental data to calculate the duration of air pumping was calculated. The analysis of the obtained dependencies of the duration of air pumping out from the system "teat cup - pulsator"system allowed to recommend the most rational options of the pneumatic and electromagnetic pulsator, provided that it will be provision of the mode of smooth shockless opening of milking cup teat rubber at 48 kPa vacuum pressure and the volume of variable vacuum-gauge pressure chambers of the system "teat cup - pulsator" 10-4 m3.

Opis:
The article presents analytical dependences for simulating the process of filling the chambers of variable vacuum-gauge pressure of the system of pulser-teat cup with air. The simulation is carried out with an account of the law of mass saving for controlled volumes of gases by means of equation of mechanical energy of air transportation. The paper calculates the time of filling chambers of milking units with air to the conditions of atmospheric pressure.

Opis:
The article shows the importance of the problem of improving efficiency of energy use in technical and technological systems. One of the ways of improving energy efficiency of water supply systems is the use of new energy-efficient technologies and pumping equipment, the use of modern management systems. Modern trends in the evaluation of energy consumption for operation of pumping equipment of water supply systems were analyzed. New methods of improving energy efficiency of pumping units in water supply system, taking into account the real operating conditions, were presented.
