Abstract
This paper presents a theoretical and experimental study on the determination of the efficiency of a hydraulic gear pump based on an analysis of the hydraulic fluid temperature at the inlet and outlet ports. Considering the thermodynamics and fluid mechanics equations, the steady state behavior of the gear pump is described for different wear conditions. The model establishes the relationship between the inlet and outlet temperatures and the main variables such as pressure, torque, flow, and angular speed and, consequently, the pump efficiency.
