Definitions

  • the present invention relates to a method for operating a two-cylinder high-pressure pump or a drive device for a two-cylinder high-pressure pump according to the preamble of claim 1 or the preamble of claim 9.
  • Two-cylinder high-pressure pumps are used, for example, for conveying concrete.
  • the concrete z. B. pumped via appropriate distribution booms on significant heights and distances.
  • the delivery cylinders are connected via a switch, in particular a diverter valve to a common delivery line, wherein the switch alternately connects one or the other delivery cylinder with the delivery line, so that overall results in a nearly continuous flow of the thick material or concrete.
  • FIG. 2 shows a hydraulic drive for a two-cylinder high-pressure pump with a pipe switch.
  • the block diagram shown is a so-called single-circle system in which the drive cylinders 1, 2 of the delivery cylinders FR, FL and the setting cylinders SZ of the transfer tube are supplied with hydraulic oil only by means of a supply device or the working pressure is generated.
  • This single supply device has two pumps P1 and P2, which are connected via the oil lines L1 and L2 with a switching block 3, depending on the operating state, the pumped by the pumps P1 and P2 oil via lines L4 the one drive cylinder 1 or the drive cylinder 2 for the delivery cylinder FR and FL or via further lines L4a the adjusting or swivel cylinder SZ of the pipe switch RW is available.
  • Two-circuit system to realize (s. Fig. 3 ), in which the pumps P1 and P2 are provided separately for the drive cylinders 1 and 2 of the delivery cylinders FR and FL on the one hand and for the adjusting or swivel cylinder SZ of the transfer tube RW on the other hand.
  • the pumps P1 and P2 are provided separately for the drive cylinders 1 and 2 of the delivery cylinders FR and FL on the one hand and for the adjusting or swivel cylinder SZ of the transfer tube RW on the other hand.
  • two independent pumping devices each with at least one pump P 1 and P2, ie a so-called.
  • Two-circuit system is provided. This makes it possible to operate the delivery cylinder and the adjusting cylinder or time parallel to shorten the delivery interruption.
  • the disadvantage here is that two separate pumping devices must be present, in particular, the pump P1 must be designed to be correspondingly large in order to provide the necessary hydraulic oil volume flow for the operation of the drive cylinder 1 and 2 available.
  • the invention is based on the recognition that in a drive of the drive cylinder or delivery cylinder of a two-cylinder high-pressure pump by means of a fluid, in particular a hydraulic oil, in the end region of the piston movement, ie at the end of a piston stroke no longer full drive power is needed. Based on this knowledge, it is then possible to shorten the switching time by using the no longer required drive power, that the drive power is no longer required already for the operation of the switch, especially for the drive of a pan or actuator cylinder for a pipe switch use. Thus, it is no longer necessary to wait until the piston stroke in the drive or delivery cylinder has ended, but the switching process and thus the operation of the transfer tube can be initiated already before the end of a piston stroke.
  • a fluid in particular a hydraulic oil
  • the invention provides to monitor or determine the position of the piston in the drive cylinder or delivery cylinder and determine at least in a certain position shortly before reaching the end position, so that starting from this information, a portion of the fluid volume flow, preferably hydraulic oil flow for the actuation of the adjusting or pivoting cylinder of the switch can be provided.
  • the determination device used therefor can be of a mechanical, electrical or hydraulic nature, with the latter in particular offering itself when the entire control of the drive largely takes place by means of a fluid or hydraulic oil. Namely, corresponding switching valves can be used in a simple manner, which are controlled via known hydraulic control lines.
  • a corresponding detection device for detecting the piston position of the adjusting cylinder of the pipe switch may be provided to use this information for the switching operation.
  • the hydraulic circuit can be constructed so that two pumping devices used to provide a corresponding fluid flow or operating pressure are used, which are comparable to the two-circuit system primarily independent on the one hand for driving the drive cylinder and on the other hand for driving the actuating or pivoting cylinder for the switch. Due to the inventive idea that shortly before the required switching operation of the switch, the drive power for the drive or delivery cylinder no longer must be 100%, the two independent pumping devices can be combined in such a way that during the piston stroke of the drive cylinder or Delivery cylinder, the second pumping device provides their capacity for the drive or delivery cylinder available, while shortly before the switching operation, the second pumping means is used exclusively for the actuation of the actuating or pivoting cylinder of the switch. In this way, it is possible to effectively use the pumping or delivery of the drive or to use components with lower power.
  • the drive is designed so that the operating pressure in particular of the second pumping device is present during the entire operation of the actuating or swivel cylinder.
  • the deflection of the fluid volume flow can be realized in a simple manner by a corresponding switching valve, so that the circuit complexity can be kept very low overall.
  • Fig. 1 shows a block diagram of a hydraulic drive of a two-cylinder high-pressure pump with a first drive cylinder 1 and a second drive cylinder 2, which are connected via the respective pistons with a first delivery cylinder FR and a second delivery cylinder FL.
  • the delivery cylinders FL and FR are connected via a pipe switch RW to a common delivery line, so that a nearly continuous delivery rate for the thick material is achieved by the alternating stroke of the delivery cylinders FL and FR.
  • the pipe switch RW must be alternately brought into a connecting position between the first conveyor cylinder FR and the common conveyor line or second conveyor cylinder FL and common conveyor line via a control or swivel cylinder SZ.
  • two pumping devices P1 and P2 are provided, each of which may have one or more pumps connected in parallel. In the block diagram shown only one pump is shown for each pumping device.
  • the pumping devices P1 and P2 are connected via the supply lines L1 and L2 to the control block 3, are received in the switching valves 3.1 and 3.2, which in turn are connected to the hydraulic lines L4 and L4a.
  • an intermediate line for mutual connection is provided, in which a switching valve 6 is installed, so that hydraulic oil, which is conveyed in the supply line L1 through the first pumping device P1 can be pumped into the second supply line L2.
  • the switching valve 6 has the task that hydraulic oil, which is pumped by the second pumping device P2 in the supply line L2, to maintain a sufficient oil flow to actuate the drive cylinders 1 and 2 can pass into the first supply line L1.
  • the hydraulic oil in the supply line L1 is then alternately through the switching valve 3.2 via the supply lines L4 the first drive cylinder 1 and the second drive cylinder 2 provided to operate on these the delivery cylinders FR and FL. Via the line L9 the oil return occurs.
  • switching valves VFR and VFL are provided, by means of which the alternating stroke movement of the drive cylinders 1 and 2 is controlled. Because of the alternating stroke movement of the drive cylinders 1 and 2, these are hydraulically coupled to one another via the control lines SL5, SL6, SL7 and SL9.
  • the switching valves VFR and VFL also simultaneously form so-called proximity switches, by means of which the piston position in the drive cylinders 1 and 2 can be determined. At the same time are acted upon by the corresponding positions of the piston in the drive cylinders 1 and 2 connected to the switching valves VFR and VFL control lines SL8 and SL10, which in turn control the switching valves 3.1 and 3.2 in the control block 3 and the switching valve 6 accordingly.
  • the diverter when changing the delivery stroke from the delivery cylinder FR to the delivery cylinder FL or vice versa, the diverter must be operated by the adjusting or swivel cylinder SZ accordingly.
  • the actuating cylinder SZ is supplied via the switching valve 3.1 through the second pumping device P2 and the supply lines L2 and L4a with corresponding hydraulic oil or pressurized.
  • the switching valve 6 is triggered by the hydraulic signals by means of the control lines SL8 and SL10, the switching valve 3.1 and the switching valve 6 are switched over the switching valve 6 before reaching the respective Kolbenend ein the drive cylinder 1 or 2 accordingly.
  • the switching valve 6 in this case blocks the connecting line between the supply lines L1 and L2 in such a way that no more oil flow from the supply line L2 in the supply line L1 and thus can reach the supply of the drive cylinder 1 and 2. Rather, the delivery rate of the second pumping device P2 is completely provided to the swivel cylinder SZ, wherein by the corresponding hydraulic control lines SL18 and SL19 and the switching valve VSZ for controlling the actuating or
  • Swivel cylinder SZ is actuated or this outputs corresponding control signals to the changeover valve 6.
  • the oil volume flow which is usually used by the second pumping device P2 for the actuation of the drive cylinders 1 and 2, in the final movement of the respective drive cylinders 1 and 2, in which this volume flow is not absolutely necessary, early for an actuation of the pivoting cylinder can be used, so that the delivery interruption of the slurry pump is reduced.
  • the second pumping device P2 is connected via the supply line L2 directly to the switching valve 3.1 or via the hydraulic lines L4a to the swivel or actuating cylinder SZ, the operating pressure of the second pumping device P2 is available to the swivel cylinder SZ during the entire operation.
