Functional Features

The aim of this article is to create a control system for a constant hydraulic power source pressure, a pump -battery power source equipped with an original design of the hydraulic pump discharge machine that provides relay switching of its operation mode. This aim is achieved by using a simulation method based on the application of volumetric stiffness theory of hydraulic systems and their elements. As a result of a numerical experiment conducted by solving the equations that make up the mathematical model of power supply, its main technical characteristics and the influence of its main design parameters on its functional features and operational properties are obtained. The obtained results showed that by changing the various design parameters of unloading machine, it is possible not only to change the upper (maximum) and lower (minimum) values of the battery charging pressure, but also to adjust their difference depending on the requirements for the power source. The main result of this study is that as a result of a numerical experiment, it is proved that the unloading machine provides a clear relay switching of the pump operation mode from unloading to operating mode and Vice versa. The identified properties make a very promising use of a pump -battery power source in the hydraulic systems of mobile machines and process equipment.
