  • the present invention seeks to develop a device and a method, which even without the usual today cylinder switch sensors reliable pump operation can be ensured with continuous concrete flow.
  • the solution according to the invention is based above all on the knowledge that, with the inclusion of a computer control, additional operating data can be evaluated from the hydraulic circuit for controlling the reversing pump and the pipe switch.
  • the solution according to the invention consists essentially in that a sensor for monitoring the hydraulic pressure on the high-pressure side of the reversing pump is provided, whose output signal can be evaluated with a pressure monitoring routine of the reversing device for triggering a diverter pipe reversal and reverse flow of the reversing pump.
  • a mean pump pressure can be determined and stored during each pressure stroke.
  • the pressure monitoring routine then has an algorithm for determining a pressure increase occurring at the end of each pressure stroke in the respective drive cylinder relative to the mean pressure value and for converting it into a changeover signal for the transfer tube and / or the reversing pump.
  • the reversing device is a computer-aided arrangement for determining the anticipated stroke duration and their registration in a data memory and time monitoring during each piston stroke and to initiate a Rohr originallyum facedung and reverse flow of the reversing pump according to a defined, compared to estimated lift time has elapsed stroke time.
  • the reversing device preferably has a time monitoring routine which has an algorithm for determining a comparison value from the stroke time and the anticipated stroke duration and for converting it when a predetermined value in a reversing signal for the diverter switch and / or the reversing pump is exceeded.
  • the reversing device has an input routine for storing the measured during a calibration of the concrete pump at least one defined flow rate stroke duration. Since the delivery rate can be varied in computer-aided concrete pumps, for example via a remote control device, it is particularly advantageous if the reversing device has a calculation routine for converting the registered stroke duration as a function of the set on a remote control unit flow.
  • the reversing device may also have a selected on the output signals Zylinderschaltsensoren Wegschreibwachungsroutine for triggering the Rohr originallyum penetrateung and / or reverse flow of the reversing.
  • the reversing device may additionally have a measuring routine for determining the duration of stroke from the output signals of the cylinder switching sensors and for their registration. That way in a data store Registered stroke duration can be used in an emergency to control the flow reversal.
  • a preferred embodiment of the invention provides that the path monitoring routine which responds to selected cylinder shift sensors, the pressure monitoring routine responding to the pressure measurement values and the time monitoring routine responding to the lift time form a preferably hierarchically structured, redundant program sequence for reversing the pipe switch and / or the reversing pump.
  • the control according to the invention switches over the reversing pump when the bottom-side cylinder switch is reached during normal operation and thus ensures a continuous flow of concrete.
  • the respective stroke duration is calculated during operation and the mean high pressure at the pressure output of the reversing pump is determined and stored in data memories.
  • the controller for the continued operation of the pump can be automatically switched to at least one of the bottom-side Zylinderschaltsensoren.
  • the rod-side cylinder shift sensors are indeed prioritized. In operation, however, the rod and the bottom side cylinder switching sensors are monitored and can be activated independently of each other for the aforementioned measuring operations.
  • the stroke time since the last switching operation can be monitored and compared with the registered stroke duration.
  • the estimated stroke time can be calculated as a function of the flow rate, the speed or the viscosity of the conveyed material. If the stroke time has nearly expired, then the high pressure compared at the pump outlet with the mean stored high pressure of the current stroke. In the case of an increase in the pressure above a predetermined threshold, a forced reversal can be initiated in this case.
  • the measures described above can also be used individually for reversing the diverter valve and the reversing pump.
