Abstract
In this article, the authors want to present the benefits of digital hydraulics, by presenting a Digital Hydraulic Pumping System (DHPS), consisting of 4 fixed flow pumps, driven by a biaxial electric motor, 4 3/2 on/off directional valve, a 4/2 type directional valve and a bidirectional hydraulic motor. With the help of a micro-controller, the 4 3/2 directional valve, which independently control the output of each pump, are operated in a certain sequence, so that a regulation of the flow provided in the system in 15 discrete points is obtained. Due to the construction of the 3/2 directional valve (directional valve with port P to T), but also of the microcontroller, a variation of the flow supplied in the system with low energy losses is obtained. This system is designed within the digital hydraulics laboratory of the INOE 2000-IHP Research Institute, in order to obtain preliminary results, which will also lead to its physical realization.
