Abstract

This paper presents a way of determining the coefficient k8 of the pressure losses ΔpMp (flow drag) in internal ducts of SWSB-63 hydraulic motor. The coefficient is determined at a flow rate equal to the theoretical capacity QPt of the pump feeding the motor, the losses are related to the nominal pressure pn in the hydraulic system. The investigations followed a model of energy performance of hydraulic rotary motor, proposed by Z. Paszota.
