dc.description.abstractThe constructional design of a milking cluster requires a scientific solution to some contradictive tasks. A rapid emptying of a milk chamber of the claw from milk provides a suitable background for a further process of the milk flow. Scientific works prove that excessive speed of a milk-air mixture in a long milk tube has some negative impact on milk quality. The scientists have determined some boundary conditions of milk transporting speed in a long milk tube. The influence pattern of mechanical and technological specifications of a milking claw on the flow speed in a long milk tube under condition of keeping the milk quality indices requires some scientific solution. The influence of the milk flow intensity, long milk tube diameter, as well as of the intensity of air delivery into the milk chamber of claw on the milk flow speed in a flexible milk tube has been proved. Under condition of invariant geometric parameters of a milk claw, the flow speed of milk increases in proportion to the milk flow intensity due to a higher pressure gradient. The regime of a milk-air mixture flow is characterized by a long milk tube diameter and by the geometric parameters of the throttle hole. The diameter and the length of a long milk tube determine the pressure drop of a transporting chain “claw-milking pipeline”. The milk flow intensity has great influence on the pressure drop when transporting the milk portions to the milk transfer line. Under the condition of invariant long milk tube diameter, the pressure drop increases when the milk flow intensity grows. In the structure of pressure drops, the ones within the long milk tube length have the highest specific weight, and the supporting piers have the lowest losses. The optimal correlation between the parameter of the milk chamber of the claw, long milk tube diameter and the throttle hole diameter has been determined. It provides safe milk transporting irrespective of the milk flow intensityen
