Tytuł:: Energy losses in the hydraulic rotational motor definitions and relations for evaluation of the efficiency of motor and hydrostatic drive

Tematy:: hydrostatic drive

energy efficiency
Opis:: The evaluation methods of energy losses and efficiency of the hydraulic rotational motors for the hydrostatic drives, used so far in the scientific research and in the industrial practice, give wrong results because the parameters that the losses and efficiencies are a function of are themselves dependent on those losses. The aim of the paper is to define the motor operating parameters, developed powers, energy losses and efficiencies and also to show the respective relations. Conclusions are drawn, based on the analyses of presented definitions and relations, on the motor energy investigations.

Tytuł:: Theoretical and mathematical models of the torque of mechanical losses in a hydraulic rotational motor for hydrostatic drive
Autorzy:: Paszota, Z.

Data publikacji:: 2010
Wydawca:: Politechnika Gdańska. Wydział Inżynierii Mechanicznej i Okrętownictwa
Tematy:: hydrostatic drive
hydraulic motor
energy efficiency
Opis:: The paper presents theoretical and mathematical models of the torque of mechanical losses in a hydraulic rotational motor with constant capacity qMt per one shaft revolution (with constant theoretical working volume VMt) and with variable capacity qMgv = bM qMt per one shaft revolution (with variable geometrical working volume VMgv). The models are to be used in the laboratory and simulation investigations of motor energy losses aimed at evaluation of the motor energy efficiency and hydrostatic drive efficiency.

Tytuł:: Method of sum of power losses as a way for determining the ki coefficients of energy losses in hydraulic motor
Autorzy:: Maczyszyn, A.
Powiązania:: https://bibliotekanauki.pl/articles/259421.pdf
Data publikacji:: 2016
Wydawca:: Politechnika Gdańska. Wydział Inżynierii Mechanicznej i Okrętownictwa
Tematy:: hydrostatic drive
power of energy losses
hydraulic rotary motor
Opis:: 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.

Tytuł:: Energy loss coefficients ki in a displacement pump and hydraulic motor used in hydrostatic drives
Autorzy:: Maczyszyn, Agnieszka
Powiązania:: https://bibliotekanauki.pl/articles/259211.pdf
Data publikacji:: 2019
Wydawca:: Politechnika Gdańska. Wydział Inżynierii Mechanicznej i Okrętownictwa
Tematy:: hydrostatic drive
energy loss rate
pump
hydraulic motor
energy loss coefficients
Opis:: The article aims at defining and analysing the energy loss coefficients in design solutions of rotating displacement machines, with a piston machine as an example. The energy losses observed in these machines include mechanical loss, volumetric loss, and pressure loss. The scale and relations between these losses in different machines depend on machine design and manufacturing quality, and on operating parameters. The operating parameters, in turn, which affect directly or indirectly the above losses depend on whether the machine works in pump or hydraulic motor regime. The article is also a contribution to the development of a library of ki coefficients which define the losses in displacement machines, as the knowledge about these coefficients makes it possible to assess fast and easily the energy efficiency of a machine or drive system at each point of its working area.

Tytuł:: Investigation method and mathematical model of pressure losses in hydraulic rotary motor
Autorzy:: Maczyszyn, A.
Powiązania:: https://bibliotekanauki.pl/articles/259344.pdf

Tematy:: hydrostatic drive
power values of energy losses
hydraulic rotary motor
pressure losses
pressure efficiency
Opis:: 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.
