Abstract

Abstract The presented test results are an example of simulating determination of the hydrostatic field of the drive system and the energy efficiency of the system as a dependence on the speed and load coefficients of the hydraulic motor used in the system. The issues related to the determination of energy losses and energy efficiency of the hydraulic motor or drive system, which should be determined as dependent on the physical quantities independent of these losses, were also discussed. A Paszota diagram of the power increase in the direction opposite to the direction of the power flow, replacing the Sankey diagram of the power decrease in the direction of the power flow in the hydraulic motor or in the drive system was analyzed.
