Hydraulic drive for a pressure tranducer

摘要

The drive (1) has a pressure medium pump (10) comprising a constant displacement pump (11) i.e. internal gear pump, and conveying constant volume per revolution. A servo motor (12) i.e. frequency-regular drive motor, is coupled to drive the medium pump. A controller is structured to one of electrically control, regulate and switch the servo motor. The servo motor is arranged on one of a low pressure side (13) and a high pressure side (14) of a pressure booster (15). The controller receives signals from signal generators in a closed loop.
