摘要： The invention relates to a hydraulic drive, especially for two-cylinder thick matter pumps. Said hydraulic drive comprises at least one main pump (10) embodied as a hydraulic variable displacement pump, and two hydraulically actuatable drive cylinders (20, 22) that are each connected to a connection line (16, 18) of the main pump (10) by means of pump connections mounted on one end thereof, forming a closed hydraulic circuit, and communicate with each other at the ends thereof opposing the pump connections (24, 26) by means of a swinging oil line (28). The hydraulic drive also comprises a feed pump (42), by which means pressurized oil is fed from an oil tank to the current low-pressure side into the hydraulic circuit, and a flushing branch (52), by which means a flushing oil flow is branched off from the current low-pressure side under a limited pressure into the oil tank (44). In order to avoid low-pressure influxes during the reversal process of the main pump (10), the flushing oil flow is blocked and then released in a time-delayed manner during each reversal process of the main pump (10), independently of the differential pressure in the connection lines.

摘要： A thick matter pump comprising a drive motor (50), a (reversible) hydraulic pump (6), and two hydraulic cylinders (5, 5′) coupled to conveyor cylinders (7, 7′) for conveying the thick matter. A regulator regulates the rotational speed N of the drive motor (50), and a regulating clement (18, 20) regulates the displacement volume V of the hydraulic pump (6). A control module (54) regulates the rotational speed N of the motor and the displacement volume V. For improved operational ease and reduction of fuel requirements, noise and waste gas emission, the control module (54) comprises a final control element (56) for regulating the conveyance capacity of the conveyor cylinders (7, 7′), and an electronic control unit (108) which reacts to the position of the final control element (56) and allocates a nominal value to the rotational speed regulator and to the displacement volume regulator (20), in a software-assisted manner.
