Abstract (en)
[origin: CA2905976A1] Hydraulic drive for pressure booster of a high-pressure apparatus, having an electric servo drive effectively connected to electrical supply operable to be regulated and/or switched by measurement signals; a hydraulic pump, pumping a constant volume of working fluid per revolution, and driven by the electric servo drive, and measuring devices for a pressure and/or a pressure trend of the working fluid and/or a pressure and/or a pressure trend of the high-pressure fluid and/or for a position of a piston in the pressure booster. Servo drive is embodied bidirectionally, such that an application of working fluid to the pressure booster is reversible. Control of regulating and/or switching parameters of the electrical supply of the servo drive is based on signals from the measuring devices for the pressure and/or the pressure trend of the working fluid and/or the high-pressure fluid and/or for the position of the piston in the pressure booster.
