  • the invention relates to a pump device with a drive motor and a fluid pump coupled to it, which has a pump housing with at least one suction-side inlet channel and one pressure-side outlet channel, and with a pressure vessel that is communicatively connected to the outlet channel of the fluid pump.
  • Such pump devices which are also referred to as automatic domestic water machines, are known from the prior art. They serve to convey a fluid, in particular drinking or service water, from a source or from a storage vessel into a water supply network, which can be provided, for example, to supply a building and / or a garden.
  • a pumping device is, for example, from DE-29909020-U1 known.
  • the subject matter of claim 1 is delimited in two-part form from this publication.
  • the pumping device has a drive motor, which can in particular be designed as a mains-operated electric motor, and a fluid pump coupled to it.
  • the fluid pump is typically designed as a single or multi-stage self-priming centrifugal pump and comprises an impeller which is received in a pump housing and which can be driven by the drive motor.
  • a suction-side inlet channel and a pressure-side outlet channel are attached to the pump housing, which enable an inflow of fluid to the pump wheel and an outflow of the fluid pressurized by the pump wheel, for example into the water supply network.
  • a pressure vessel is connected to the discharge channel and communicates with the pressurized fluid. The pressure vessel is provided in order to prevent the drive motor from being switched on and off frequently due to the loss of pressure in the event of any leaks in the water supply network.
  • the pressure vessel which is designed as a pressure accumulator, provides a limited volume of fluid which is pressurized by means of the fluid pump and which ensures an essentially constant water pressure at least when small amounts of fluid flow out into the water supply network.
  • flexible lines for hydraulic or electrical coupling and to compensate for mechanical positional tolerances are provided between the fluid pump and the pressure tank.
  • the object on which the invention is based is to create a pumping device that ensures simplified manufacture and more reliable function.
  • a pump device in which at least two functional assemblies are provided, in which the drive motor with the fluid pump on the one hand and the pressure vessel on the other hand are integrated, the functional assemblies being spatially compact to one another and connected to one another. Between the drive motor with the fluid pump and the pressure vessel, defined interfaces are provided for a fluid-carrying connection, which can be produced without additional, especially flexible adapter parts, as used in known pump devices to compensate for tolerances, and thus the desired spatially compact arrangement of the Ensure functional modules to each other.
  • fluid line sections of a fluid line running between the at least two functional assemblies are connected to one another by at least one fluid-tight plug connection.
  • plug connections which already ensure a fluid-tight connection between a plug-in receptacle and a pipe section designed to be plugged into the plug-in receptacle
  • an advantageous assembly of the functional assemblies can be achieved.
  • the plug-in receptacle and the correspondingly designed pipeline section of the functional assemblies to be connected which in particular can each be integrally formed on the functional assemblies, are plugged together during the final assembly of the pumping device and directly form the fluid-tight connection during the plugging process.
  • This can be achieved in particular by providing corresponding sealing surfaces and sealing means such as sealing rings, which come into operative connection during the plugging process, on the plug-in receptacle and the pipe section.
  • the functional assemblies are assigned a plug-in receptacle and / or a pipe section for a coaxial, in particular detachable plug connection in the direction of a central longitudinal axis of a volume section delimited by the plug-in receptacle and the pipe section.
  • a space-saving and reliably sealing arrangement of the sealing means in particular circularly circumferentially around the volume section delimited by the plug-in receptacle and the pipe section, can thus be achieved.
  • the pipe section and the plug-in receptacle can have a circular, non-circular or polygonal cross-section in a cross-sectional plane arranged orthogonally to the central longitudinal axis of the volume section.
  • plug-in receptacle and the plug-in area of the pipe section are provided for a detachable plug-in connection. This facilitates the replacement of individual functional assemblies, for example in the event of a repair, so that the pump device can be repaired inexpensively in the event of damage.
  • the Plug connection assigned at least one safety device for a mechanical lock.
  • the securing device mechanically couples the pipeline section and the plug-in receptacle with one another in order to avoid undesired separation of the plug-in connection, for example due to pressure loads, vibrations or other external influences.
  • the mechanical coupling of the plug-in receptacle with the pipe section can in particular be effected by a U-shaped securing clip, which is pushed on orthogonally to the central longitudinal axis of the volume section delimited by the plug-in receptacle and the pipe section in the plug-in area and creates a form fit.
  • a reliable mechanical coupling which can preferably be produced and / or released without tools, can be ensured by a contour of the securing clip that is adapted to the pipeline section and / or the plug-in receptacle.
  • the fluid line comprises at least one dimensionally stable pipe as a fluid line section.
  • a compact design of the pumping device can be achieved through the use of dimensionally stable pipelines, since dimensionally stable, preformed pipelines, compared to flexible hoses, which must not fall below a minimum radius of curvature, enable a stronger deflection of fluid flows in a smaller space.
  • An assembly of the pipelines is simplified since dimensionally stable pipelines are easier to handle than the pliable hose sections known from the prior art, in particular with regard to the exertion of assembly forces on the plug-in area or areas.
  • the final assembly of the pumping device can also be automated, since the pipeline or the functional assembly provided with the pipeline can be gripped, for example, by an industrial robot and the position of the plug-in area or areas is fixed by the dimensionally stable design, so that a automated plugging process can take place.
  • the pipeline section and / or the plug-in receptacle which are necessary for a simple, tight and possibly detachable plug connection, can be molded directly, in particular in one piece. It is not necessary to press on hose sleeves or to create a plug-in area in any other way. This ensures greater reliability of the connections between the pipeline, pipeline section and plug-in receptacle.
  • at least essentially all functional assemblies are connected to one another in a hydraulically communicating manner by means of dimensionally stable pipelines, which can in particular be designed as plastic parts.
  • a further functional assembly includes a pressure switch which is assigned to the discharge channel on the pressure side.
  • the pressure switch is provided for pressure-dependent switching on and off of the drive motor and enables the drive motor to be activated in the event of a pressure loss in the water pipe network in order to convey fluid into the water pipe network and thus ensure an essentially constant fluid pressure in the water pipe network.
  • a pressure loss in the water supply network can be caused, for example, by drawing water from a tap such as a tap.
  • the drive motor is activated by the pressure switch and the fluid pump again pumps fluid into the water supply network and the pressure accumulator.
  • a rigid pressure line is provided on the drainage channel, which is designed for a communicating connection of the drainage channel to the pressure switch and / or a manometer.
  • a separate pipeline designed as a rigid pressure line enables different pressure switches and / or manometers to be individually adapted to the pumping device.
  • the pump device can thus be adapted in a simple manner to different areas of application.
  • Corresponding plug-in receptacles and / or pipe sections are provided on the pressure line, on the drainage channel and on the pressure switch, so that automated assembly can also be provided.
  • At least one check valve is arranged in the inlet channel, which check valve is designed to block a fluid pressure that can be applied by the fluid pump.
  • the check valve prevents the fluid pressure built up by the fluid pump from dropping as a result of fluid flowing out into the inlet channel.
  • the check valve is in particular provided with a pre-tensioned return spring and is designed in such a way that when the fluid pump starts up, it opens the inlet channel due to the negative pressure created in the pump housing and enables fluid to flow from the source or the storage vessel.
  • the check valve is assigned an actuating device which is provided for pressure-independent control of the check valve.
  • the actuation device is provided in order to facilitate the suction process of the fluid pump, which would otherwise be impeded by the typically closed check valve, when the pump device is reinstalled, in particular when the fluid pump is not filled.
  • the actuation device allows manual or automatic
  • the check valve is opened by an associated operating lever or an automatic control device. With the pressure-independent control of the check valve, the flow resistance for the fluid is reduced so that the fluid pump can self-priming.
  • the actuating device is arranged in the inlet channel so as to be rotatable about a pivot axis which is arranged orthogonally to the central longitudinal axis of the inlet channel.
  • a filter assembly is provided as a further functional assembly, which has an in particular sleeve-shaped filter device in the inlet channel.
  • the filter device prevents damage to the fluid pump by particles contained in the fluid, such as grains of sand, for example.
  • the integration of the filter device into the inlet channel enables a particularly compact design and ensures a particularly favorable and low-loss flow through the filter device.
  • the filter device is designed for a radially inwardly flowing fluid flow and that a cup-shaped collecting container is assigned to an end region of the filter device.
  • At least one end plug is assigned to the inlet channel, which end plug is provided for closing an access to the check valve and / or the filter device. Maintenance of the filter device and / or the non-return valve is thus facilitated, since only the end plug has to be removed from the inlet channel, which can in particular be done without tools. The filter device and / or the check valve are then accessible for maintenance work or can be removed from the inlet channel in order to be able to carry out maintenance work.
  • the check valve and the filter device are each assigned an end plug so that, for example, the check valve can be removed from the inlet channel in the vertical direction downwards, while the filter device can be removed in the vertical direction upwards.
  • the drive motor and the pressure switch are each assigned correspondingly designed multiple plug devices for a releasable electrical connection.
  • the multiple plug devices enable all electrical connections to be created between the drive motor and the pressure switch with one plugging process, so that the pressure switch can be coupled or uncoupled from the drive motor without complex cabling work.
  • this also improves the test option for these two functional assemblies during the manufacturing process, since only the plug connection between the drive motor or the pressure switch and a suitable test device has to be established for test processes.
  • a flexible membrane is fixed to the pressure vessel by means of a flange section which has a plug-in device with a fluid channel for a communicating connection between the drain channel and a compensation space enclosed by the membrane.
  • the flange section thus ensures the fastening of the membrane to the pressure vessel as well as the communicating connection with the discharge channel of the fluid pump.
  • a fluid channel is provided in the flange section, starting from the plug-in device, which opens into the compensation space enclosed by the membrane.
  • the plug-in device enables an assembly-friendly plug connection of the flange section with the correspondingly designed drainage channel.
  • the flange section is formed in one piece on the drainage channel and is designed in particular as a plastic injection-molded part.
  • At least two drainage channels are provided on the pump housing, at least one of which is designed in the manner of a siphon and / or has a vent valve arranged above the fluid pump.
  • the vent valve When the fluid pump is started up, the vent valve enables a simplified initial filling in which the air enclosed in the fluid pump has to be displaced by the fluid in order to achieve an adequate pumping effect.
  • the pump device is already connected to the water supply network when it is put into operation, so that the air contained in the fluid pump cannot simply flow off into the environment.
  • the vent valve arranged and opened above the fluid pump allows the enclosed air to escape when it is filled with the fluid.
  • the functional assembly comprising the pressure vessel has a frame which surrounds the pressure vessel, which has at least one standing surface and which is provided with at least one mounting surface for connection to the functional assembly comprising the fluid pump.

  • the frame surrounds the pressure vessel in a form-fitting manner and can be screwed to the screw socket of the pressure vessel.
  • the standing surface or several feet ensure that the pressure vessel stands securely on the ground.

  • the mounting surface is provided on an upper frame part as an interface for a bearing plate.
  • the drive motor is attached to the end shield, which is designed at least in sections as a pump housing. This ensures that an exact positioning of the drive motor and a pump wheel attached to the shaft of the drive motor relative to the pump housing can be guaranteed.
  • the fluid pump can therefore be implemented with small positional tolerances, so that a particularly advantageous degree of efficiency of the fluid pump can be achieved.
  • the end shield is provided with a receptacle for the drive motor which, in particular, enables a positive connection between a reference geometry of the drive motor, for example a cylindrical flange, and the end shield.
  • a precisely concentric arrangement of the drive motor with respect to a central longitudinal axis of the fluid pump can thus be ensured.
  • the pump wheel attached to the shaft of the drive motor is thus also aligned concentrically with the part of the pump housing realized in the end shield.
  • Further housing parts can also be provided with reference geometries that can engage in corresponding reference geometries of the end shield and / or the pump housing and can thus also be arranged with small positional tolerances.
  • a mounting surface for attachment to the frame of the pressure vessel is provided on the end shield, which is designed in particular for a reproducible alignment of the end shield with respect to the pressure vessel, preferably with at least one positioning pin.
  • This also ensures precise positioning relative to the frame of the pressure vessel on the part of the end shield. With a small number and precise design of the interfaces between the functional assemblies, an exact alignment of the functional assemblies with one another can be guaranteed. This enables the use of rigid pipelines, although there may be a static overdetermination between the functional assemblies due to the coupling of the functional assemblies.
  • tolerance compensation which in the prior art is ensured by flexible pipelines, can be achieved solely by the sealing means, for example designed as O-rings.
  • the drive motor and / or the fluid pump are at least substantially surrounded by an air guide housing which is designed in such a way that contact with moving or hot components of the drive motor is excluded.
