METHOD FOR OPERATING A CONSTRUCTION-MATERIAL AND/OR VISCOUS-MATERIAL PUMP FOR CONVEYING CONSTRUCTION MATERIAL AND/OR VISCOUS MATERIAL, AND CONSTRUCTION-MATERIAL AND/OR VISCOUS-MATERIAL PUMP FOR CONVEYING CONSTRUCTION MATERIAL AND/OR VISCOUS MATERIAL

摘要

The invention relates to a method for operating a construction-material and/or viscous-material pump (1) for conveying construction material and/or viscous material (DS), the construction-material and/or viscous-material pump (1) comprising: - at least one conveying cylinder (2a, 2b), the conveying cylinder (2a, 2b) being designed to receive and discharge construction material and/or viscous material (DS); and - at least one conveying piston (3a, 3b), the conveying piston (3a, 3b) being disposed in the conveying cylinder (2a, 2b) for movement in order to draw construction material and/or viscous material (DS) into the conveying cylinder (2a, 2b) and to displace drawn-in construction material and/or viscous material (DS) out of the conveying cylinder (2a, 2b); and the method comprising the steps of: - conveying construction material and/or viscous material (DS), by means of movement of the conveying piston (3a, 3b) in order to draw in and displace construction material and/or viscous material (DS); - sensing at least one position variable (PGa, PGb) during the movement, the position variable (PGa, PGb) characterizing a position (POa, POb) of the conveying piston (3a, 3b) along its stroke (HU) in the conveying cylinder (2a, 2b); - sensing at least one conveying variable (FG', FG'') during the movement, the conveying variable (FG', FG'') being of a different type than the position variable (PGa, PGb) and characterizing the conveying of construction material and/or viscous material (DS) by means of the construction-material and/or viscous-material pump (1); and - determining a profile (PR) of a subsequent movement of the conveying piston (3a, 3b) by linking the sensed position variable (PGa, PGb) and the sensed conveying variable (FG', FG'') to each other; and - at least controlling the subsequent movement in accordance with the determined profile (PR).
