Title:
A device for drive control of a 2-cylinder type thick substance pump
Document Type and Number:
Japanese Patent JP6194360
Kind Code:
B2
Abstract:
A device for the drive control of a two-cylinder thick matter pump has a diverter which is arranged in a material charging container and a motor-driven hydraulic variable displacement pump, via which both the drive cylinders of the thick matter pump and the drive mechanism of the diverter are controlled. An adjusting throttle is arranged in a pressure line between the high-pressure outlet of the variable displacement pump and the drive cylinders of the thick matter pump. A control line which leads to an adjusting mechanism of the variable displacement pump is coupled back from the pressure line downstream of the adjusting throttle. A connecting line which leads to a supply connector of the diverter hydraulics and in which a fixedly adjusted throttle can be arranged is branched off from the pressure line upstream of the adjusting throttle.
