Abstract

The device (1) for the increasing of the pressure in the water supply, especially of high buildings, has a pressure increasing pump unit (3) which is supported in a cavity (10) formed by a pipe (2) in order to be interconnected in a water pipe. Spring elements (11) are installed between the pump outer side and pipe inner side to keep the pump unit centered. At least two spring elements are distributed uniformly over the circumference of the pump unit.

Description

Die Erfindung betrifft eine Vorrichtung zum Erhöhen des Druckes in der Wasserversorgung, insbesondere von höheren Gebäuden, mit einem Druckerhöhungspumpenaggregat, das koaxial in einem von einem Rohr gebildeten Raum gelagert ist, um in eine Wasserleitung zwischengeschaltet zu werden.The The invention relates to a device for increasing the pressure in the water supply, especially from higher ones buildings, with a booster pump unit, which is mounted coaxially in a space formed by a pipe, to be interposed in a water pipe.

Es ist bekannt, zur Druckerhöhung in einer Wasserversorgung ein Pumpenaggregat in ein Edelstahlrohr zu lagern und hierbei das Aggregat mittels Stahlbolzen im Rohr zu zentrieren. Dabei hat sich gezeigt, dass die Montage aufwendig ist und die Pumpengeräusche nach außen in einem erheblichen Maße übertragen werden.It is known to increase the pressure in a water supply, a pump set in a stainless steel pipe store the aggregate by means of steel bolts in the pipe Center. It has been shown that the assembly is expensive and the pump sounds outward transferred to a considerable extent become.

Aufgabe der Erfindung ist es, eine Vorrichtung der Eingangs genannten Art so zu verbessern, dass bei einfacher und kostensparender Bauweise eine Geräuschminderung erzielt wird.task The invention is a device of the type mentioned to improve so that in a simple and cost-saving design a noise reduction is achieved.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass zwischen der Pumpenaußenseite und der Rohrinnenseite Federelemente angeordnet sind, die die Pumpe zentrierend halten.These Task is inventively characterized solved, that between the pump outside and the tube inside spring elements are arranged, which the pump keep centering.

Eine solche Lagerung des Pumpenaggregats innerhalb des Rohres durch Federelemente führt zu einer erheblichen Geräuschminderung. Darüber hinaus sind Herstellung und Montage vereinfacht, da die Federelemente vor dem Einsetzen des Aggregats in das Rohr auf der Aggregataußenseite befestigt werden können.A Such storage of the pump unit within the tube by spring elements leads to a significant noise reduction. About that In addition, production and assembly are simplified because the spring elements attached to the outer side of the unit before inserting the unit can be.

Vorzugsweise wird vorgeschlagen, dass die zentrierenden Federelemente elastisches Material insbesondere Gummi und/oder elastischen Kunststoff aufweisen. Auch ist es von Vorteil, wenn drei Federelemente über den Umfang des Aggregats regelmäßig verteilt sind.Preferably It is proposed that the centering spring elements elastic Material in particular rubber and / or elastic plastic. Also, it is advantageous if three spring elements on the Scope of the unit regularly distributed are.

Eine besonders einfache Befestigung der Federelemente auf der Außenseite des Aggregats wird dann erreicht, wenn über den Federelementen ein umlaufendes Band insbesondere eine Schlauchschelle liegt, das die Federelemente an der Aggregataußenseite hält.A particularly simple attachment of the spring elements on the outside the aggregate is then reached when over the spring elements a circulating belt is in particular a hose clamp that the Spring elements on the outside of the unit holds.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Es zeigenOne embodiment The invention is illustrated in the drawing and will be described below described in more detail. Show it

1: einen axialen Schnitt durch die erfindungsgemäße Vorrichtung und 1 an axial section through the device according to the invention and

2: einen Querschnitt nach II-II in 1. 2 a cross-section according to II-II in 1 ,

Die Druckerhöhungsvorrichtung 1 in der Wasserversorgung eines höheren Gebäudes oder für andere Zwecke weist ein Rohr 2 auf, in dem koaxial ein Pumpenaggregat 3 in einer Weise gelagert ist, dass zwischen der Aggregataußenseite und der Rohrinnenseite ein Ringraum 4 besteht. Beide Enden des insbesondere aus Edelstahl bestehenden Rohres 2 sind durch Metallscheiben 5, 6 insbesondere durch Flansche verschlossen, die jeweils eine mittige Öffnung besitzen, an der ein Rohrstutzen 7, 8 außen befestigt ist. An der der Ausgangsseite befestigten Scheibe/Flansch 5 ist das Pumpenaggregat 3 mit seinem Druckstutzen 9 angeschraubt.The pressure-increasing device 1 in the water supply of a higher building or for other purposes has a pipe 2 on, in the coaxial with a pump unit 3 is mounted in a manner that between the unit outer side and the pipe inside an annular space 4 consists. Both ends of the particular stainless steel tube 2 are through metal discs 5 . 6 in particular closed by flanges, each having a central opening, on which a pipe socket 7 . 8th attached outside. On the output side fixed disc / flange 5 is the pump unit 3 with his discharge nozzle 9 screwed.

Am gegenüberliegenden (axialen) oder seitlich angebrachten (radialen) Zulaufstutzen 8 strömt das Wasser mit geringem Druck in den Innenraum 10 des Rohres 2 ein, um zur Saugöffnung des Pumpenaggregats 3 zu gelangen.At the opposite (axial) or laterally mounted (radial) inlet nozzle 8th the water flows into the interior at low pressure 10 of the pipe 2 to go to the suction opening of the pump set 3 to get.

In dem Ringraum 4 zwischen dem Pumpenaggregat 3 und der Innenwand des Rohres 2 sind zwei oder mehr Federelemente 11 angeordnet, die über den Umfang des Aggregats gleichmäßig und damit in denselben Winkelabständen verteilt sind.In the annulus 4 between the pump unit 3 and the inner wall of the pipe 2 are two or more spring elements 11 arranged, which are evenly distributed over the circumference of the unit and thus at the same angular intervals.

Diese Federelemente sorgen dafür, dass das Pumpenaggregat 3 nicht nur am auslassseitigen Ende, sondern auch in einem mittleren Bereich im Rohr sicher zentriert gehalten ist. Hierbei stellen die Federelemente 11 eine Schallentkopplung dar. Die Federelemente 11 bestehen vollständig oder teilweise aus einem elastischem Material, insbesondere aus Gummi und/oder aus einem elastischen Kunststoff.These spring elements ensure that the pump set 3 not only at the outlet end, but also in a central region in the tube is securely centered. Here are the spring elements 11 a sound decoupling. The spring elements 11 consist entirely or partially of an elastic material, in particular of rubber and / or of an elastic plastic.

Die Montage der Federelemente 11 wird dadurch erleichtert, dass vor dem Einsetzen des Pumpenaggregates 3 in das Rohr 2 vom druckseitigen Ende her die Federelemente mit einem umlaufenden Band 12, insbesondere einer Schlauchschelle, auf die Außenseite des Pumpenaggregats befestigt werden und erst danach das Pumpenaggregat in das Rohr eingeschoben wird. Hierbei ist die Anzahl der Federelemente 11 nicht auf zwei beschränkt, sondern es können auch mehr Federelemente angeordnet werden. Ferner können die Federelemente nicht nur aus einem einzigen Material, sondern auch aus mehreren Materialien, insbesondere schichtweise aufgebaut sein.The assembly of the spring elements 11 is facilitated by the fact that before the onset of the pump unit 3 in the pipe 2 from the pressure end, the spring elements with a circumferential band 12 , In particular a hose clamp, are attached to the outside of the pump unit and only then the pump unit is inserted into the pipe. Here is the number of spring elements 11 not limited to two, but it can also be arranged more spring elements. Furthermore, the spring elements can be constructed not only of a single material, but also of a plurality of materials, in particular in layers.
