Definitions

  • the invention relates to a Hochdruckplungerpumpe according to the preamble of claim 1 and a method for interrupting the operation of a fluid flow.
  • Hochscherplungerpumpen find for the partial processing of different materials use, for example, for roughening metals, for which purpose by means of the Hochlichplungerpumpe a working pressure up to about 4000 bar is generated.
  • This Hochdruckplungerpumpe The essential components of this Hochlichplungerpumpe are an oscillating drivable plunger, which displaces a sucked liquid volume in the working space of the pump, a suction and an outlet valve, which control the liquid flow and the liquid effluent, and a drive device which generates an oscillating motion.
  • a plurality of plunger assemblies each with an oscillating plunger and a suction and pressure valve are operated in parallel. It is through the pressure valve to a hydraulic consumer, eg. A nozzle, leading pressure line and closed by the suction valve a valve seat suction.
  • the fluid flow must be interrupted for a predetermined time within which the workpiece is moved relative to the nozzle.
  • the placement of the rod or its necessary axial mobility requires appropriate sealing measures of the channel relative to the suction chamber, which on the one hand requires a corresponding manufacturing effort and on the other also does not meet the requirements in terms of life.
  • the invention has for its object to further develop a Hochdruckplungerpumpe of the generic type so that it is easier to produce and their life is significantly increased.
  • the counter-pressure device has a supply line via which the fluid is passed directly to the suction valve at low pressure, wherein a low-pressure pump is connected to the supply line for generating pressure of the control fluid, which is in operative connection with a control valve, in its closed position Suction valve is raised or remains in the open position and when opening the counter-pressure device is out of order, so that the suction valve is ready for use.
  • control valve actuation of the control valve by means of a controller, which is correspondingly programmable, depending on the desired pattern of the workpiece to be machined.
  • the suction valves of all plunger arrangements of a high-pressure plunger pump are actuated simultaneously, which takes place via the common control valve or the common low-pressure pump.
  • the supply line for the control fluid is introduced into a valve seat ring, and opens into a control channel in which a pin of the suction valve is guided, said pin acting in the manner of a piston and is connected to a valve cone of the control valve.
  • the invention leads to an optimization of the manufacturing costs as well as to a significant extension of the service life of the Hochdruckplungerpumpe.
  • the pressure valve While the suction valve is open to interrupt the fluid flow, the pressure valve is closed, as well as a shut-off valve associated with the hydraulic consumer, so that the working pressure in the pressure line remains constantly high during the interruption of the fluid flow. It follows that when closing the suction valve and opening the pressure valve and the hydraulic consumer associated with the check valve, the working pressure is available immediately.
  • FIGS. 1 and 2 a head region of a Hochdruckplungerpumpe 21 is shown, with a plunger assembly 1, which has a connected to a valve seat suction 6 and a valve seat pressure line 15 working space 16 in which a plunger 2 is arranged axially movable back and forth, according to the arrow in the FIGS. 1 and 2 ,
  • valve seat pressure line 15 is closed by a pressure valve 4 and the valve seat suction 6 by a suction valve 5, wherein the suction valve 5 is controlled by means of a counter-pressure device 7 as required in an open position preserved.
  • the counterpressure device 7 has a supply line 9, which via a connecting line 10 with a low pressure pump 20 (FIG. FIG. 3 ) is in communication, via which a control fluid on the suction valve 5 can be guided, wherein the connecting line 10 extends between the valve seat suction 6 and the pressure valve.
  • the suction valve 5 has a valve cone which is spring-loaded in the closed position of the suction valve 5 by means of a compression spring 13 against a valve seat of a valve seat ring 3, namely on the plunger 2 side facing.
  • a pin 12 acting in the sense of a piston is connected on the side facing away from the plunger 2, which is axially displaceably guided in a concentric control channel 11 of the valve seat ring 3 and into which the supply line 9 opens, so that the supplied control fluid with pressure on the end face of the pin 12 is applied.
  • the pin 12 and the channel 11 are dimensioned so that there is a low-friction gap seal between the two.
  • FIG. 2 an enlarged detail of the plunger assembly 1 in the region of the valve seat ring 3 is shown.
  • the suction valve 5 is in an open position, ie, the passage between the valve seat suction 6 and the working space 16 is open, wherein the plunger 2 is in an upper dead center.
  • a bottom dead center UT is indicated by dashed lines. Because the strokes of the plunger 2 continuously, the fluid is in a pressure stroke of the plunger 2 in the valve seat suction 6 and thus in a fluid source 22 (FIG. FIG. 3 ) pushed back.
  • control valve 19 is open as well as a check valve 18, which is a hydraulic consumer, in the example of a nozzle 17, immediately upstream, so that on the one hand closes the suction valve 5 due to the now missing control pressure and the pressure valve 4 opens while the pressure fluid through the valve seat pressure line 15th and a pressure line 8 of the nozzle 17 is supplied.
  • the low-pressure pump 20 delivers pressure-less into the fluid source 22 common to the high-pressure plunger pump 21.
  • control 23 is provided which is programmable according to the intervals of the functional interruption of the fluid flow.
  • control valve 19 and the check valve 18 are closed, so that control fluid via the low pressure pump 20 is conveyed into the control channel 11 and the suction valve 5 is kept open according to the closing time of the control valve 19.
  • FIG. 3 In the FIG. 3 are shown in a circuit diagram three plunger assemblies 1 of Hochdruckplungerpumpe 21, the suction valves 5 are simultaneously actuated.
  • the plunger arrangements 1 are designed in such a way that, as a function of the fluid pressure prevailing at the nozzle 17, they remain the same over the entire service life.
  • FIG. 4 is a functional measuring blade of Hochdruckplungerpumpe 21 is shown according to the invention, wherein on the ordinate axis of the operating pressure and on the abscissa axis the operating times are applied.
