Mit einer solchen Vorrichtung kann ein Wasserversorgungs/ Druckerhöhungssystem aufgebaut werden, welches in der Haus- und Gebäudetechnik, aber auch in vielen anderen Bereichen wie in der Industrie, Kühlwasserkreisläufen etc. eingesetzt werden kann. Es ist eigenständig funktionsfähig als Einzelaggregat sowie auch als integrierte Einheit bzw. Box als Baustein einer Anlage, die aus den unterschiedlichsten Anordnungskombinationen mehrerer Vorrichtungen bzw. Einheiten (Boxen) bestehen kann.With such a device, a water supply / pressure booster system can be set up, which can be used in house and building technology, but also in many other areas such as in industry, cooling water circuits etc. It functions independently as a single unit and also as an integrated unit or box as a component of a system that can consist of a wide variety of arrangement combinations of several devices or units (boxes).

Die Vorrichtung weist ein segmentiertes Kunststoff- oder Edelstahlbauelement quadratischer Grundfläche auf, in das alle mechanischen, hydraulischen und elektrischen/elektronischen Elemente einer Wasserversorgungs- bzw. DE-Anlage integriert sind. Die Wände sind (wenn aus Kunststoff gebaut) im Sandwichverfahren aufgebaut aus z. B. zwei Mantelhäuten aus GFK und einer integrierten Stütz- bzw. Schalldämmschicht aus PU oder einer Stützschicht aus einem wabenförmigen Gitter. Alle notwendigen Anschlußstutzen sind in diesen Mantel einlaminiert oder eingespritzt bzw. eingeschweißt, sofern der Mantel aus Edelstahl gefertigt wird.The device has a segmented plastic or stainless steel component with a square base, in which all mechanical, hydraulic and electrical / electronic elements of a water supply or DE system are integrated. The walls are (if built from plastic) built in the sandwich process from z. B. two outer skins made of GRP and an integrated support or sound insulation layer made of PU or a support layer made of a honeycomb grid. All necessary connecting pieces are laminated or injected or welded into this jacket, provided the jacket is made of stainless steel.

Die Pumpe 1 wird von einem Elektromotor angetrieben, der direkt an der Pumpe befestigt, insbesondere angeflanscht ist. Pumpe und Motor besitzen jeweils ein eigenes Gehäuse. Im folgenden wird diese Pumpen-Motoren-Einheit als Pumpe 1 bezeichnet, wobei die unterschiedlichsten Pumpenbauarten verwendet werden können. Auch kann die Pumpe mehrere Pumpenstufen besitzen, wie dies in den Figuren 2 und 4 dargestellt ist.The pump 1 is driven by an electric motor which is attached directly to the pump, in particular flange-mounted. The pump and motor each have their own housing. In the following, this pump-motor unit is referred to as pump 1, and a wide variety of pump types can be used. The pump can also have several pump stages, as shown in FIGS. 2 and 4.

Die Pumpe 1 ist von einem Außengehäuse 2 umgeben, das quaderförmig ist und damit vier senkrechte Außenwände 3 besitzt, wobei der Übergang von einer senkrechten Außenwand in die benachbarte durch eine Abrundung 4 erfolgt.The pump 1 is surrounded by an outer housing 2, which is cuboid and thus has four vertical outer walls 3, the transition from one vertical outer wall to the adjacent being effected by a rounding 4.

An den Unterseiten der Außenwände 3 ist ein waagerechter Boden 5 angeformt und auf der Oberseite der Außenwände 3 ist eine Abdeckhaube 6 insbesondere lösbar befestigt, deren Außenseiten die Form eines Pyramidenstumpfes haben und unter der sich die Regelelektronik befindet. Ein an einer Außenwand der Abdeckhaube 6 befestigtes Anzeigedisplay 7 wird für die unterschiedlichsten Informationen genutzt.A horizontal base 5 is formed on the undersides of the outer walls 3 and a cover 6 is in particular detachably fastened on the upper side of the outer walls 3, the outer sides of which have the shape of a truncated pyramid and under which the control electronics are located. A display 7 attached to an outer wall of the cover 6 is used for a wide variety of information.

Mittig im Innern des Außengehäuses 2 befindet sich eine Innenkammer 8 mit im Ausführungsbeispiel etwa waagerechtem, quadratischem Querschnitt und Wänden 9, die die Pumpe 1 im Abstand umgeben. Zwischen den vier Wänden 9 und den Außenwänden 3 befindet sich rundum ein Abstand, der zwei Außenkammern 10,11 bildet. Die Außenkammern 10,11 sind gleich groß und durch zwei senkrechte Querwände 12,13 voneinander getrennt.An inner chamber 8 with an approximately horizontal, square cross section in the exemplary embodiment and walls 9 which surround the pump 1 at a distance is located in the center of the inside of the outer housing 2. Between the four walls 9 and the outer walls 3 there is a space all around, which forms two outer chambers 10, 11. The outer chambers 10, 11 are of the same size and are separated from one another by two vertical transverse walls 12, 13.

Die erste Außenkammer 10 weist als Saugkammer drei oder mehr Saugstutzen 14 auf, die in den verschiedenen drei Außenwänden 3 angeordnet sind, die diese Kammer 10 umgrenzen. In gleicher Weise weist die zweite Außenkammer 11 als Druckkammer drei oder mehr Druckstutzen 15 auf, die wiederum in drei unterschiedlichen Außenwänden 3 angeordnet sind. Durch dieses Anordnen der Saug- und Druckstutzen in zwei oder mehr Außenwänden, die zueinander rechtwinklig angeordnet sind, kann die Vorrichtung auf die unterschiedlichsten Anschlußarten an weiteren Vorrichtungen gleicher oder ähnlicher Bauart befestigt werden, wobei dann die Stutzen der Vorrichtungen miteinander fluchten.The first outer chamber 10 has, as a suction chamber, three or more suction ports 14 which are arranged in the various three outer walls 3 which delimit this chamber 10. In the same way, the second outer chamber 11 has three or more pressure ports 15 as a pressure chamber, which in turn are arranged in three different outer walls 3. By arranging the suction and pressure ports in two or more outer walls, which are arranged at right angles to each other, the device can be attached to a wide variety of connection types on other devices of the same or similar type, in which case the connectors of the devices are aligned.

Die beiden Außenkammern 10,11 umgeben somit die Innenkammer 8 ringförmig und damit auf den Außenseiten vollständig, so daß diese mit Wasser gefüllten Außenkammern 10,11 nicht nur eine hohe Schalldämpfung, sondern auch eine Wasservorlage bilden.The two outer chambers 10, 11 thus surround the inner chamber 8 in a ring and thus completely on the outer sides, so that these outer chambers 10, 11 filled with water form not only a high level of sound absorption, but also a water reservoir.

Die Innenkammer 8 ist auch mit Wasser gefüllt und mit der ersten Außenkammer (Saugkammer) über eine unten in der Wand 9 angeordnete Durchflußöffnung 16 mit einer von innen angebrachten Ringabsperrklappe absperrbar verbunden. Das aus der Pumpe kommende Druckwasser wird über ein Verbindungsrohr 17, das sich oberhalb der Kammern 8 und 11 befindet, in die zweite Außenkammer 11 geführt. Alternativ kann aber auch über ein Rohr das Fördermedium von der ersten Außenkammer 10 (Saugkammer) zur Saugöffnung der Pumpe geführt werden, so daß die Pumpe in die Innenkammer 8 hinein fördert und die Innenkammer mit der zweiten Außenkammer 11 über eine Öffnung in der Wand 9 verbunden ist.The inner chamber 8 is also filled with water and is connected to the first outer chamber (suction chamber) via a flow opening 16 arranged at the bottom in the wall 9 and can be shut off with an internally mounted ring shut-off valve. The pressurized water coming from the pump is fed into the second outer chamber 11 via a connecting pipe 17, which is located above the chambers 8 and 11. Alternatively, however, the pumped medium can also be fed from the first outer chamber 10 (suction chamber) to the suction opening of the pump via a pipe, so that the pump delivers into the inner chamber 8 and the inner chamber is connected to the second outer chamber 11 via an opening in the wall 9 is.

Eine Verbindung der Saug- und Druckstutzen 14,15 einer Vorrichtung mit denen der anderen kann über kurze Verbindungsrohre bzw. Verbindungshülsen 18 (Figur 11 oder durch Adapter 19 - 21, aber auch Figur 12 bis Figur 14) erfolgen, wobei die Adapter entweder zwei Flansche oder ein Außengewinde bzw. Innengewinde besitzen. Stutzen 14, 15, die nicht benötigt werden, können durch einen Verschlußstopfen 22 (Figur 15) verschlossen werden.The suction and pressure ports 14, 15 of one device can be connected to those of the other via short connecting pipes or connecting sleeves 18 (FIG. 11 or by adapters 19-21, but also FIGS. 12 to 14), the adapters either having two flanges or have an external thread or internal thread. Stubs 14, 15 that are not required can be closed by a plug 22 (FIG. 15).
