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

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.
