Definitions
- the invention relates to a device and a method for controlling a thick matter pump with two delivery cylinders which open into a material feed container via front openings and can be actuated in a push-pull manner by means of a hydraulic reversing pump and controlled hydraulic drive cylinders with a feed cylinder arranged inside the material feed container and alternatingly on the openings of the
- the delivery cylinder can be connected and the other opening opening and connected on the outlet side to a delivery line, hydraulically actuated pipe switch, with each delivery stroke at at least two sensor positions located at predetermined distances from each other and from the rod and / or bottom ends of the drive cylinder detected and a reversal process of the reversing pump and the pipe switch is triggered at the end of a delivery stroke.
- a device for controlling a two-cylinder thick matter pump of this type is known (DE 195 42 258), in which the end positions of the pistons of the drive cylinders can be tapped by means of cylinder switching sensors for generating end position signals.
- the flow reversal of the reversing pump can be triggered there via the end position signals of the drive cylinders.
- the end position signals are usually triggered via the two rod-side cylinder switching sensors.
- a certain switchover time is required within which the swash plate present in a reversing pump can be moved through.
- the switchover times for common reversing pumps are approx. 0.1 sec. With a two-second stroke, this switching time speaks about 5% of the stroke.
- the object of the invention is to develop a device and a method for controlling a thick matter pump of the type specified at the outset, with which a complete emptying of the cylinders is possible with each piston stroke and nevertheless an undesired striking of the pistons at the ends of the drive cylinders is avoided.
- the solution according to the invention is based on the idea that movement detection of the drive pistons is possible with at least two cylinder switching sensors arranged at arbitrary locations on the working cylinders, which are arranged at a distance from one another and from the two end positions Software allow a complete recording of the movement sequence of the pistons along the working cylinders and thus a solution to the problem specified above.
- the computer-aided reversing device has a measurement and evaluation routine for the measurement and / or calculation of the chronological sequence of movements of the pistons on their way between the two cylinder ends and for calculating a triggering time derived therefrom has a reversal of the reversing pump and the pipe switch.
- a preferred embodiment of the invention provides that the measurement and evaluation routine takes into account an algorithm for recording the piston passage at the location of the cylinder switching sensors as well as for calculating a triggering time derived therefrom for reversing the reversing pump and the pipe switch with each piston stroke a predetermined or calculated braking time of the pistons until the respective stop at the cylinder end.
- the braking time of the pistons essentially consists of the response time of the reversing relay and the switching time of the reversing pump.
- a time for triggering the reversing pump and the pipe switch can be assigned to each time interval that is measured as a reference value for the speed.
- the time can be recorded, for example, using the changeover pulse for the pipe switch.
- the distance between two switch points then corresponds to the stroke duration.
- the triggering time for the reversal is then determined. This value is approximately constant for one and the same pump type.
- a special feature arises when the flow rate is changed within a pump stroke. In this case, the new delivery rate must be taken into account and converted into a corresponding remaining term in order to determine the exact triggering time.
- a preferred embodiment of the invention accordingly provides that the measurement and evaluation routine include an algorithm for calculating the speed of the pistons on their way between the cylinder switching sensors and a triggering time derived therefrom for the reversing processes, taking into account a predetermined or calculated braking time of the pistons up to the respective end stops in the cylinders.
- Algorithm for determining the course of the piston speed and of the derived next triggering time for the reversal processes in accordance with the currently set default values It is particularly advantageous if the measurement and evaluation routine has an algorithm for determining the braking time or the braking distance of the pistons in accordance with the currently measured or calculated piston speed and a triggering time derived therefrom for the switching processes.
- the chronological sequence of movements of the pistons on their way between the two cylinder ends is measured and / or calculated, and the next triggering time for the reversal processes is derived therefrom.
- a preferred embodiment of the invention provides that the piston passages at the location of the cylinder switching sensors are recorded in relation to one another in time and that the triggering time for the subsequent reversal of the reversing pump and the diverter valve is taken into account, taking into account a predetermined or calculated braking time of the pistons to the respective End stop on the cylinder is calculated.
- the speed of the pistons on their way between the selected cylinder shift sensors can be calculated and the next point in time for the reversal processes can be derived from this.
- a further preferred procedure consists in that the chronological sequence of movements of the pistons is changed via remote-controlled default values for the delivery quantity and that the next triggering time for the reversing operations is derived from the sequence of motions of the pistons calculated according to the default values, taking into account a modified braking time.
- the braking time or the braking distance of the pistons from the measured or calculated instantaneous piston speed, taking into account the device-specific response and changeover times of the reversing pump is determined and the next trigger point is calculated from it.
- Figure 1 shows a section of a two-cylinder slurry pump in a partially sectioned diagram.
- FIG. 2 shows a circuit diagram of a computer-assisted drive hydraulics for the two-cylinder thick matter pump
- FIG. 3 shows a detail from FIG. 2 with some dimensions for calculating a preferred triggering time
- 5 shows a flowchart of the measurement and triggering routine.
- the control arrangement shown in FIGS. 2 and 3 is intended for a thick matter pump according to FIG. 1.
- the thick matter pump has two delivery cylinders 50, 50 ', the end openings 52 of which open into a material feed container 54 and can be connected alternately to a delivery line 58 via a pipe switch 56 during the pressure stroke.
- the delivery cylinders 50, 50 ' are driven by hydraulic drive cylinders 5.5' and a reversing hydraulic pump 6 in push-pull.
- the delivery pistons 60, 60 'of the delivery cylinders 50, 50' are connected to the pistons 8, 8 'of the drive cylinders 5.5' via a common piston rod 9, 9 '.
- the drive cylinders 5, 5 ' are connected on the ground side via hydraulic lines 11, 11' of the hydraulic circuit using the Reversing pump 6 is pressurized with pressure oil and is hydraulically connected to one another at its rod-side end via a rocking oil line 12.
- the direction of movement of the drive pistons 8,8 'and thus the common piston rod 9,9' is reversed by reversing the direction of flow of the reversing pump 6 via a reversing device 18 containing a computer 14 and an adjustment mechanism 16.
- the reversing pump 6 has a swash plate 62, which is swiveled through its zero position during reversal, so that the direction of delivery of the pressure oil in the hydraulic lines 11, 11 ′ is reversed.
- the delivery rate of the reversing pump 6 can be varied at a given speed of a drive motor, not shown, by the swivel angle of the swash plate 62.
- the swivel angle of the swash plate 62 can be adjusted via a remote control device 64 with the support of the computer 14.
- the reversing pump and the pipe switch 56 are reversed as soon as the pistons 8, 8 'of the drive cylinders 5, 5' reach their end position.
- the reversing device utilizes output signals of the cylinder switching sensors 20, 22 and 20 ', 22 ⁇ which are arranged at a distance from the rod-side and bottom ends of the two drive cylinders 5, 5' and which are connected on the output side to the computer 14 of the reversing device 18.
- the cylinder switching sensors respond to the drive pistons 8,8 'that pass during pump operation and signal this event to the computer input 66,68.
- a reversal signal 76 is triggered in the reversing device, which reverses the reversing pump 6 via the adjusting mechanism 16.
- a reversal of the pipe switch 56 via the directional control valve 79 and the plunger cylinders 72, 72 ' is also triggered via a signal 77.
- the signals from the cylinder switching sensors 20, 20 'on the rod side are primarily used to generate a reversing signal.
- the computer 14 has a measurement and evaluation routine 40 (cf. FIG. 5) in which the output signals of the cylinder-side cylinder switching sensors 20, 20 'are evaluated to form a reversing signal 76, 77 for the reversing pump 6 and / or the pipe switch 56.
- the rod-side cylinder switching sensors 20, 20 ' are denoted by Si and S 2 . Accordingly, the sensor positions from the bottom end of the drive cylinders are denoted by Xsi and Xs 2 , while the useful length of the cylinder, which is calculated from the cylinder length minus the piston length, is denoted by Xz y ⁇ . This is the maximum piston stroke.
- the positions Xsi, Xs 2 of the cylinder switching sensors and the effective length Xz y ⁇ are known.
- the aim of the invention is to calculate a position X x or the associated time t x for the piston passage at the point X x , from which the reversing pump must be reversed so that a complete piston stroke can be achieved without hitting the cylinder bottom hard.
- This position depends on the flow rate, but is independent of the position of the cylinder shift sensors (see Fig. 4).
- the speed VK of the piston results from the length of use Xz y ⁇ and the stroke time as well as the acceleration and braking distances and times Xßeschi, X ⁇ rems, tßeschi, terems:
- Xx Xzyl - Xßrems where, for simplification, a constant braking acceleration b bre m s is assumed:
- the braking time is determined accordingly
- a more precise determination of the triggering time is possible if the information of the piston run through the switch positions Si or S 2 is also added. For example, the time between the start of the stroke and switch 1 is calculated as x s l xS 1 v '' stroke ⁇ cyl
- the triggering time can also be determined when the delivery quantity changes.
- the effective length Xz y ⁇ must be divided depending on the change in the delivery rate and the new speed VK of the piston used to calculate the braking time. This is known due to the specified delivery rate.
- the flowchart of the measurement and evaluation routine 40 in FIG. 5 illustrates the measurement and control processes during the piston movement in the working cylinders.
- the time tsi and ts 2 of the piston passing by is determined and the theoretical stroke time t H u b is calculated therefrom. If the delivery rate is changed in the meantime, this affects the stroke time t ⁇ u b and thus also the piston speed.
- These values are then taken into account in the calculation of the tripping time, which ultimately leads to the triggering of the reversing movements in the pipe switch and in the reversing pump at the time t x or ⁇ t x .
- a lead time for the stroke time is specified in parallel with the event measurements on the cylinder switch sensors, which, independent of the measurement processes on the cylinder switch sensors, reverses the via a parallel branch Diverter and the reversing pump can trigger.
- the invention relates to an apparatus and a method for controlling a two-cylinder engine. Thick matter pump, the delivery pistons of which are actuated in a push-pull manner by means of a hydraulic reversing pump 6 and hydraulic drive cylinders controlled by this.
- the delivery cylinders 50, 50 ' are connected to a delivery line 58 with a pressure switch 56 with each pressure stroke. At the end of each pressure stroke, a reversal process of the reversing pump 6 and the pipe switch 56 is triggered.
