Investigation method and mathematical model of pressure losses in hydraulic rotary motor

Maczyszyn A.

Polish Maritime Research

2018

nr 1

93--98

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.

Method of sum of power losses as a way for determining the ki coefficients of energy losses in hydraulic motor

Maczyszyn A.

Polish Maritime Research

2016

nr 2

57--67

This paper shows application of the method of sum of power losses to determining energy losses which occur in hydraulic rotary motor in situation when not all laboratory data are at one’s disposal or when no use is made of data contained in catalogue charts. The method makes it possible to determine the coefficients, ki, of energy losses occurring in the motor. The method of sum of power losses is based on the approach proposed by Z. Paszota, in the papers [3 ÷ 9]. It consists in adding power flow of energy losses occurring in the motor to power flow output and comparing the sum to the power flow input. Application of the method is exemplified by using a A6VM hydraulic motor.
