Abstract

The paper presents theoretical and mathematical models of the torque of mechanical losses in the pump with theoretical (constant) capacity q_Pt per one shaft revolution (with constant theoretical working volume V_Pt) and geometrical (variable) capacity q_Pgv per one shaft revolution (with variable volume V_Pgv). The models may be used in the laboratory and simulation investigations of the pump energy efficiency and the hydrostatic drive efficiency.
