Digital pump controller in the press

Marvin Schell, development engineer from Andreas Lupold Hydrotechnik GmbH dealt with the development of a novel pump control based on a digital hydraulic pump controller in his publication “beyond digital”. He outlined how this control combines the advantages of digital technology with those of hydraulics to provide optimized pump management.

This digital hydraulic pump controller uses its own poppet valves (pulsed universal leakfree solenoid valve, pulse for short), which are leakfree due to their principle and can be switched in a few milliseconds. The basic controller type, can be adjusted live to the system needs via software, a change from a pressure controller to a flow or capacity controller is thus possible during operation. The flexibility of the system is increased enormously with these Hydraulic Pulse Controllers (HPC) and controller losses are also minimised.

Schell’s publication was aimed at engineers and technicians interested in the latest developments in hydraulic control systems. He presented the basics of digital hydraulics and explained how it can be combined with conventional hydraulics. The project is geared to the future requirements of the fluid industry and solves problems through approaches such as digitalization, increased efficiency and flexibility, hydraulics as a programmable component, and reductions in the number of variants.
