Definitions

  • the invention relates to a modular system for fluid pump devices with at least one coupling piece and with at least one fluid pump.
  • EP-B-1 210 519 an apparatus for pumping fluid with a hydraulic pump and a drive device is known, wherein the hydraulic pump as a fluid pump is a gear pump and coupled as a separate component with different types of drive means as further components in the manner of a modular system and designed for this purpose as a one-piece coupling piece.
  • the respective hydraulic tank can be connected as a tank unit from one side to the coupling piece and the respective drive means of the other opposite side of the coupling piece to this.
  • the coupling piece on at least one side on a flange and further sealing means between the coupling piece and drive means and the respective hydraulic tank are provided to effectively counteract leakage.
  • the present invention seeks to further improve the known modular system while maintaining its advantages, namely functionally reliable and space-saving, to further increase the possibilities of variation of different embodiments at low manufacturing cost level, so as to allow flexible fluid control for fluid pump devices.
  • a pertinent task solves a modular system with the features of claim 1 in its entirety.
  • the connecting lines are arranged within the coupling piece, a special structure is achieved, which is very quiet during operation of the device, including contributes to that in a preferred embodiment of the modular system according to the invention, the coupling piece is centrally penetrated by a passage point, the Passing through a drive train is used, which leads from the drive device to the fluid pump.
  • the device shown in Figure 1 is used for pumping and thus the delivery of fluid, in particular in the form of hydraulic medium, by means of a fluid pump 12 which is drivable by a drive means 14 in the form of an electric motor.
  • the fluid or hydraulic pump 12 is an independent modular component with various types of drive means 14 as further components in the manner of a modular system can be coupled and for this purpose the fluid pump 12 engages with drive device 14 in the direction of the Fig.1 seen from the front end to a coupling piece 16 at.
  • various hydraulic tanks 18 may be provided, in particular with different tank volumes, the respective hydraulic tank 18, as viewed in the direction of FIG. 1, engaging the coupling piece 16 from the front end side.
  • fluid pump 12 projects, starting with its connection point, on the coupling piece 16 into the interior of the respectively connected hydraulic tank 18.
  • the basic structure of fluid pump devices according to the illustration according to FIG. 1 is known in the prior art, so that at this point this will not be discussed in detail.
  • connecting lines 20, 22, 24, 26 and 28 extend within the coupling piece.
  • placeholders 1 to 10 are integrated into the said connecting lines as so-called vacancies the optional insertion of Fluidbaukomponenten 1 to 10 'as shown in FIG.
  • connection lines 20,22,24,26,28 results in particular from the circuit diagram and component overview according to the representations according to Figures 2 and 3.
  • the fluid components 1 'to 10' according to FIG. 3 can occur in order to obtain obvious hydraulic controls, as complementarily represented in FIG. 5 as an embodiment. 2 shows, the circuit diagram of the modular system is characterized in that the connecting lines 20, 22, 24, 26 and 28 are located inside the coupling piece 16 are interconnected such that at least one placeholder 1 to 10 is integrated between two connection points 30 of a connecting line, in each of which an adjacent connection line opens.
  • Fluidbaukomponenten 1 'to 10' as shown in Figure 3 can also occur other Fluidbaukomponenten, for example in the form of filters, hydraulic accumulators, cooling units, heat exchangers, coupling and terminators including fluid branches and measuring devices, such as pressure and Temperaturmeßtechnik (not ) shown. It is also possible, instead of fluid components 1 to 10 ', to allow other valve components to occur or to connect further components (not shown) to the existing components.
  • fluid components 1 to 10 ' instead of fluid components 1 to 10 ', to allow other valve components to occur or to connect further components (not shown) to the existing components.
  • the coupling piece 16 is formed in the manner of a connecting flange, on whose opposite end faces on the one hand, the fluid pump 12 and on the other hand, their drive means 14 are arranged. Furthermore, the tank unit 18 in the form of the hydraulic tank adjoins the coupling piece 16 on the opposite side. Furthermore, the coupling piece 16 along its, in particular polygonal (square) outer periphery opening points, which partially open into the free ends of the connecting lines 20,22,24,26 and 28 or in the placeholders 1 to 10 and in which the respective fluid components. 1 'can be used to 10'. It is possible, as shown in FIG.
  • the coupling piece 16 itself can likewise have a modular construction, ie be a structural component of the modular system in terms of size and with respect to the internal fluid guide, in order to provide even more variation possibilities.
  • the coupling piece 16 is centrally penetrated by a passage 34, in the manner of a center hole, which serves to; a drive train (not shown in more detail) of the drive device 14 can drive the fluid pump 12.
  • a removal point 7 (see FIG. 4) establishes the fluid connection from the tank unit 18 via the fluid pump 12 in order to be able to remove stored fluid in this way.
  • Said removal point 7 is surrounded by the connecting lines 20,22,24 and 28, which are perpendicular to each other to the removal point 7 mutually opposite each other (see Fig.4).
  • the placeholders 1 to 10 are occupied there with fluid components 1 'to 10', wherein the component 1 'is designed as a fluid passage, 2' as an adjustable pressure relief valve, 3 'as a spring-loaded check valve, 4' as branch with connection of a further valve component 4.1 ', 5' again represents a fluid passage, 6 'a 2/2-way valve, 7' an aperture, 8 'a so-called.
  • the coupling piece 16 largely ensures an internal fluid management, any noise levels occurring are chambered by the housing of the coupling piece 16, so that a very quiet operation is ensured. Contributes to this also in that the Koppiungs committee 16 is formed as a casting, which allows the rest, a cost-effective production of the coupling piece 16. As further shown in Figure 4, the coupling piece 16 is formed with respect to its outer circumference substantially square and seen in the direction of the Fig.4 downwards projecting flange 36 are present for fixing the modular system to fixed parts of the building or preferably to other parts of the device including machine components.
