COMPLEX STAND FOR TESTING OF A GEAR PUMPS AND INVESTIGATION OF THE INFLUENCE OF THE HYDRAULIC OIL TEMPERATURE ON THE PUMP CHARACTERISTICS

Petko Tsankov, Ivan Binev, Nikola Marazov

Abstract

The work is devoted to the creation of a test bench for a gear pump with options for adjusting the parameters: operating fluid temperature, engine speed, pump load. An experimental study of the effect of hydraulic oil temperature on the characteristics of a gear pump has been made. An analytical dependence is proposed to determine the characteristic of a gear pump with regard to the temperature and pressure of the hydraulic oil.
