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 according to the feature configuration of the preamble of patent claim 1.
  • the hydraulic pump is a gear pump as a fluid pump and can be coupled as an independent component with different types of drive devices as further components in the manner of a modular system and is designed as a one-piece coupling piece for this purpose.
  • Various hydraulic tanks serve as the third type of interchangeable components, the respective hydraulic tank as a tank unit being connectable to the coupling piece from one side and the respective drive device being connectable to the coupling piece from the other opposite side thereof.
  • the coupling piece has a flange part on at least one side and, furthermore, sealing means are provided between the coupling piece and the drive device and the respective hydraulic tank in order to be able to effectively counter leakages.
  • a hydraulic compact unit is known, which is particularly short in terms of overall length and can be implemented inexpensively, since it requires only a few individual components, and the use of conventional pumps, that is to say through which the pressure medium is not deflected, is possible.
  • a so-called multifunctional flange plate is provided, which is designed as part of the housing of the drive motor. Control elements, namely pressure regulating, flow regulating or priority valves in a cartridge design, can be built into the flange plate according to the customer's requirements.
  • the DE 15 25 417 A1 describes a generic modular system for a pump unit, which is intended in particular for a central lubrication system.
  • the known solution has at least one coupling piece and at least one fluid pump, connection lines running inside the coupling piece, into which placeholders are integrated for the optional insertion of fluid components; exclusively in the form of valves.
  • the connecting lines are interconnected within the coupling piece in such a way that corresponding placeholder positions are formed between two connection points of a connecting line, into each of which an adjacent connecting line opens, into which non-return and relief valves are integrated.
  • the invention is based on the object of further improving the known modular systems while retaining their advantages, namely being functionally reliable and space-saving, in such a way that the possible variations of different embodiments are further increased at a low manufacturing cost level, to enable flexible fluid control for fluid pump devices.
  • a related problem is solved by a modular system with the features of claim 1 in its entirety.
  • a fluid in particular hydraulic control can be realized directly on the coupling piece and thus on a fluid pump device itself, which is extremely flexible , in that a wide variety of fluid components can interact with the other fluid pump device via the coupling piece.
  • a fluid component designed as a pure fluid passage is particularly important in view of the large number of fluid connection options created.
  • the additional use of valves, preferably in the form of a cartridge, allows a wide variety of different types Realize control tasks with the fluid pump device on site.
  • a fluid pump is arranged on the front side of the coupling piece in a module-like manner, which is located within the tank unit and opposite is the drive unit for the fluid pump arranged.
  • the relevant components can also be designed differently in terms of the power volume and the size and can, of course, be connected to one another via the coupling piece to complement the fluid pump device.
  • the connecting lines are arranged within the coupling piece, a special structure is achieved, which is very quiet in the operation of the device, which also contributes to the fact that in a preferred embodiment of the modular system according to the invention, the coupling piece is centrally penetrated by a passage point that the Passage of a drive train is used, which leads from the drive device to the fluid pump.
  • the in the Fig. 1 The device shown is used for pumping and therefore for conveying fluid, in particular in the form of hydraulic medium a fluid pump 12 which can be driven by a drive device 14 in the form of an electric motor.
  • the fluid or hydraulic pump 12 can be coupled as an independent modular component with different types of drive devices 14 as further components in the manner of a modular system, and for this the fluid pump 12 with the drive device 14 engages in the direction of view Fig. 1 seen from the front end to a coupling piece 16.
  • Various hydraulic tanks 18 can be provided as a further type of components, in particular with different tank volumes, the respective hydraulic tank 18 in the direction of view of the Fig. 1 seen from the front end engages the coupling piece 16.
  • the fluid pump 12, beginning with its connection point projects on the coupling piece 16 into the interior of the respectively connected hydraulic tank 18.
  • the basic structure of fluid pump devices as shown in the Fig. 1 is known in the prior art, so that it will not be discussed in detail here.
  • Connection lines 20, 22, 24, 26 and 28 run within the coupling piece, which relates to one of the end views of the coupling piece 16. Furthermore, placeholders 1 to 10 are integrated in the connection lines mentioned as so-called empty spaces for the optional insertion of fluid components 1 to 10 'as shown in the Fig. 3 .
  • connecting lines 20, 22, 24, 26, 28 with the placeholders 1 to 10 results in particular from the circuit diagram and component overview according to the representations according to Fig. 2 or 3.
  • the circuit diagram of the modular system is characterized in that the connecting lines 20, 22, 24, 26 and 28 are interconnected within the coupling piece 16 in such a way that between two connection points 30 of a connecting line, into each of which an adjacent connecting line opens, at least one placeholder 1 to 10 is integrated.
  • the fluid components 1 'to 10' as shown in the Fig.
  • valve components can also occur other fluid components, for example in the form of filters, hydraulic accumulators, cooling units, heat exchangers, coupling and end pieces including fluid branches and measuring devices such as pressure and temperature measuring devices (not shown). It is also possible to have other valve components replace the fluid components 1 to 10 'or to connect further components (not shown) to the existing components.
  • the coupling piece 16 is designed in the manner of a connecting flange, on the opposite end sides of which the fluid pump 12 and on the other hand its drive device 14 are arranged. Furthermore, on the opposite side, the tank unit 18 connects to the coupling piece 16 in the form of the hydraulic tank. Furthermore, the coupling piece 16 has junction points along its, in particular polygonal (square) outer circumference, which partially open into the free ends of the connecting lines 20, 22, 24, 26 and 28 or into the placeholders 1 to 10 and in which the respective fluid components 1 'to 10' can be used. There is the possibility, according to the representation according to the Fig.
  • the coupling piece 16 itself can likewise have a modular structure, ie, in terms of the size and in relation to the internal fluid guide, it can be a structural component of the modular system in order to create further possible variations in this way.
  • the coupling piece 16 is penetrated centrally by a passage point 34, in the manner of a central bore, which serves to enable a drive train (not shown in more detail) of the drive device 14 to drive the fluid pump 12.
  • a tapping point 7 (cf. Fig. 4 ) establishes the fluid connection from the tank unit 18 via the fluid pump 12 in order to be able to remove fluid stored in this way.
  • the named removal point 7 is surrounded by the connecting lines 20, 22, 24 and 28, which are partially opposite one another perpendicular to the removal point 7 (cf. Fig. 4 ).
  • the placeholders 1 to 10 are occupied by fluid components 1 'to 10', component 1 'being designed as a fluid passage, 2' as an adjustable pressure relief valve, 3 'as a spring-loaded check valve, 4' as a branch with connection of a further valve component 4.1 ', 5' again represents a fluid passage, 6 'a 2/2-way valve, 7' an orifice, 8 'a so-called mini measuring connection and the ports 9 'and 10' are provided with fluid-tight plugs.
  • the coupling piece 16 Due to the fact that the coupling piece 16 largely ensures internal fluid guidance, any noise levels that may occur are chambered through the housing of the coupling piece 16, so that very low-noise operation is ensured. This also contributes to the fact that the coupling piece 16 is designed as a cast part, which, moreover, enables the coupling piece 16 to be produced inexpensively. Like the further Fig. 4 shows, the coupling piece 16 is substantially square with respect to its outer circumference and looking in the direction of Fig. 4 seen downwards, projecting flange parts 36 are present for fixing the modular system on fixed parts of the building or preferably on further device parts including machine components.
