摘要： A device and a method for controlling a two-cylinder thick matter pump comprising conveyance pistons that are actuated in a push-pull manner by means of a hydraulic reversible pump (6) and hydraulic drive cylinders controlled by said pump. For each pressure stroke, the conveyance cylinders (50, 50′) are connected to a conveyance conduit (58) by means of a pipe switch (56). At the end of each conveyance stroke in the conveyance cylinders (50, 50′), a reversal process of the pipe switch (56) and the reversible pump (6) is triggered. The aim of the invention is to ensure a reliable operation of the pump, even in the event of a breakdown of switching and pressure sensors (20, 22, 24). To this end, during the calibration of the concrete pump and/or during the operation of the pump, the expected length of the stroke of the pistons (8, 8′) in the drive cylinders (5, 5′) is measured and recorded, the stroke time of each conveyance stroke is monitored and compared with the expected stroke duration, and the reversible pump (6) is respectively pivoted, reversing the flow, and/or the pipe switch (56) is reversed when the stroke time exceeds the expected stroke duration by a pre-determined value. The output signals of a pressure sensor (24) connected to the reversible pump (6) or cylinder switching sensors (20, 20′) arranged on the working cylinders can also be evaluated in order to trigger a reversal process.

摘要： The invention relates to a device and a method for controlling a two-cylinder thick matter pump comprising delivery pistons that are actuated in a push-pull manner by means of a hydraulic reversible pump (6) and hydraulic drive cylinders controlled by said pump. For each pressure stroke, the delivery cylinders (50, 50′) are connected to a delivery conduit (58) by means of a pipe junction (56). At the end of a pressure stroke, a reversal process of the reversible pump (6) and the pipe junction (56) is triggered. The aim of the invention is to obtain a targeted reversal of the reversal pump and the pipe junction, even when the deliverable quantity is varied, whereby the delivery cylinders are completely emptied, but also without pistons banging the ends of the cylinders. To this end, a computer-assisted reversal device is provided, said device comprising a measuring and evaluating routine for detecting the temporal displacement course of the piston along the path thereof between the two cylinder ends, by measurement and/or calculation, and for calculating a triggering time derived therefrom for the subsequent reversal of the reversible pump and the pipe switch.
