Abstract
A lubrication system with supply and scavenge oil gear pumps with electric drives is the subject of research. The features of the workflow in lubrication system units are analyzed and the possibility of applying a homogeneous model for the description of a fine-dispersed air-oil mixture is evaluated. The principle of construction of a mathematical model of a lubrication system based on dynamic equations of the typical processes in the nodes – the flow of the two-phase mixture, mixing of the air and liquid flows, filling cavities of gear pairs in the suction zone of the pump is outlined. The developed mathematical model is verified by comparing the calculated and experimental processes.
