Definitions

  • the invention relates to a hydraulic drive for a pressure booster in a fluid high-pressure device, in particular for a plant for water jet cutting, consisting essentially of a hydraulic pump, which per revolution promotes a constant volume of working fluid, driven by an electric servo drive, operatively connected to a rule by means of measuring signals and / or switchable power supply.
  • Hydraulic actuators for pressure intensifiers which are driven by a controllable servo drive, are state of the art.
  • a hydraulic drive which comprises a constant-flow pump with a controllable servo drive, by which constant-flow pump by means of a switching block, a two plungers having pressure booster can be acted upon with working fluid.
  • Switching over a loading of the respective working piston surfaces with a working fluid takes place, as stated above, by means of a switching block or switching block.
  • a switching block for alternately acting on the working piston surfaces of the pressure booster on the one hand represents a high constructional effort and on the other hand can introduce shocks into the hydraulic high-pressure system, in particular when switching the pressurized working fluid, which thereby causes a superimposed mechanical peak stress of the parts in addition to the static base load.
  • the servo drive is formed bidirectionally, that is to say as a reversible motor, and such an actuation of the pressure booster can be reversed with working fluid, wherein a control of the control parameters and / or the switching parameters of the electric supply of the servo drive is checked for signals from measuring devices of pressure and / or pressure curve of the working fluid and / or pressure and / or pressure curve of the high-pressure fluid and / or based on the position of the plunger in the pressure booster.
  • a switching of a pressurized working fluid by means of a switching block according to the prior art, which can naturally cause shocks is thus circumvented and according to the invention each gentle pressure build-up in the working fluid at the start of a servo drive in milliseconds or small periods accomplished.
  • Another advantage is the simplicity of the mechanical design, the high reliability and economy of such high pressure equipment seen.
  • a particularly advantageous embodiment of the drive according to the invention for a pressure booster is achieved if at least one heat exchanger in the conducting means and / or in the vessel for adjusting the temperature of the working fluid in the region of the line of the working fluid between the hydraulic pump and pressure booster and / or in the area of provision in a vessel is positioned.
  • the conducting means or lines between the hydraulic pump and the pressure booster respectively have means for feeding working fluid into the system of the hydraulic drive, in each case a return of working fluid from the pressure booster to the hydraulic pump in this one can be set with respect to the environment low pressure.
  • optimum output conditions can be set in each case for the pressure side of the hydraulic drive or the pump.
  • Low overpressure values of from 0 to about 5 bar have proven useful, possibly to prevent gas formation.
  • Fig. 1 shows a fluid high-pressure device with a hydraulic drive 1 for a pressure booster second
  • a constant flow pump 11 is driven by a servo drive 12.
  • a controlled supply 15 of the servo motor 12 controls its rotation parameter and its shutdown.
  • a feed system 4 for working fluid has, for example, a feed pump with a drive motor 40, which is connected via check valves 41, 42 to the respective guide means between the hydraulic pump 11 and pressure booster 2.
  • Such a feed system can also have a heat exchanger 5, by means of which the temperature of the working fluid inriadsgefäß is einregelbar.
  • Fig. 2 essentially shows parts of a hydraulic drive 1 for a pressure booster 2 Fig. 1
  • a heat exchanger 51 for the working fluid can be arranged in the region of a supply vessel 10 and / or the conducting means from the hydraulic pump 11 to the pressure booster 2 each have a heat exchanger 52, 53.
