Abstract

The invention relates to packaging of a pump (9), with two shells (1,2) made of heat- and/or sound-insulating material which surround the pump (9) and which, in the assembled and connected state of the pump, form a layer insulating the pump (9), the shells (1,2) having, on their inner faces, recesses (3) which are shaped in accordance with the exterior of the pump, and one of the shells having a further recess (4) whose shape matches the exterior of the pump and into which the pump (9) can be inserted in a position which is rotated through 90 degrees in relation to the position in which the pump (9) is positioned in the shells (1,2) in the first position. <IMAGE>

Description

Die Erfindung betrifft eine Verpackung einer Pumpe mit zwei Schalen aus wärme- und/oder schalldämmenden Material, die die Pumpe umgeben und im montierten und angeschlossenen Zustand der Pumpe eine die Pumpe isolierende Schicht bilden, wobei die Schalen an den Innenseiten Ausnehmungen aufweisen, die der Pumpenaußenseite nachgebildet sind.The invention relates to a packaging of a pump with two shells made of heat and / or sound-absorbing material, which surround the pump and form a pump insulating layer in the assembled and connected state of the pump, the shells having recesses on the inside that face the outside of the pump are reproduced.

Aus der US-Patentschrift 3395775 ist es bekannt, Vorrichtungen mit einer Schaumschicht zu umgeben um Vibrationen und Geräusche zu verringern. Aus der deutschen Offenlegungsschrift 1941452 ist es bekannt, Rohrarmaturen mit zwei Schalen zu umgeben, die innen Schaum aufweisen, um die Rohrarmaturen wärmeisoliert zu montieren.It is known from US Pat. No. 3,395,775 to surround devices with a foam layer in order to reduce vibrations and noises. From German published patent application 1941452 it is known to surround pipe fittings with two shells which have foam on the inside in order to mount the pipe fittings in a heat-insulated manner.

Aus der deutschen Offenlegungsschrift 3109624 ist es bekannt, Pumpen mit zwei wärmeisolierenden Schalen zu umgeben, wobei die Schalen vor der Montage als Transportschutz dienen. In dem Fall, in dem die bekannten Schalen eine Pumpe vollständig umschließen, ist zwar ein optimaler Schutz während des Transports gegeben, aber im montierten Zustand ist die Pumpe nicht mehr sichtbar, so daß weder Lämpchen noch Anzeigevorrichtungen zum Erhalt von Informationen freigelegt sind noch Bedienungselemente betätigt werden können. Werden dagegen die Schalen so ausgeführt, daß Teile der Pumpe oder des Pumpenmotors frei liegen, so ist der Schutz während des Transports nicht ausreichend.From German published patent application 3109624 it is known to surround pumps with two heat-insulating shells, the shells serving as transport protection before assembly. In the case in which the known shells completely enclose a pump, optimal protection is provided during transport, but the pump is no longer visible in the assembled state, so that neither lights nor display devices for receiving information are exposed nor are operating elements actuated can be. If, on the other hand, the shells are designed so that parts of the pump or pump motor are exposed, the protection during transport is insufficient.

Aufgabe der Erfindung ist es, eine Verpackung einer Pumpe so zu verbessern, daß sie während des Pumpentransports einen optimalen Schutz bietet und im montierten Zustand der Pumpe die Innenpumpenteile freiläßt, die für die Bedienung der Pumpe zugänglich sein müssen.The object of the invention is to improve the packaging of a pump so that it offers optimum protection during pump transport and, when the pump is in the assembled state, leaves the inner pump parts free, which must be accessible for operating the pump.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß mindestens eine der Schalen eine weitere Ausnehmung aufweist, die der Pumpenaußenseite nachgebildet ist und in die die Pumpe in einer Stellung einsetzbar ist, die um 90 Grad verdreht ist zu der Stellung, in der die Pumpe in der ersten Stellung in den Schalen einliegt.This object is achieved in that at least one of the shells has a further recess, which is modeled on the outside of the pump and in which the pump can be used in a position which is rotated by 90 degrees to the position in which the pump in the first Position in the shells.

Durch eine solche Ausführung kann die Pumpe in zwei unterschiedlichen Lagen in der Verpackung einliegen. In der ersten für den Transport verwendeten Lage umgibt die Verpackung die Pumpe vollständig und in der zweiten Lage sind die für Bedienung und Information notwendigen Teile freigelegt, so daß in der zweiten Lage die Pumpe die Montagestellung einnimmt.With such a design, the pump can be placed in two different positions in the packaging. In the first position used for transport, the packaging completely surrounds the pump and in the second position the parts necessary for operation and information are exposed, so that in the second position the pump assumes the assembly position.

Die Verpackung besitzt eine vordere Schale 1 und eine hintere Schale 2, die im zusammengesetzten Zustand außen einen Quader bilden und aus wärmedämmendem und/oder schalldämmendem Material insbesondere Polypropylen bestehen. Jede der beiden Schalen weist auf der Innenseite eine Ausnehmung 3 auf, die zusammen eine Form bilden, die den Außenkonturen der Pumpe in der Transportstellung entspricht. Hierbei kann an manchen Stellen die aus beiden Ausnehmungen 3 bestehende Gesamtausnehmung an manchen Stellen größer ausgeführt sein als die Pumpenaußenform, so daß an manchen Stellen die Transportausnehmung nicht an der Pumpenaußenseite anliegt.The packaging has a front shell 1 and a rear shell 2 which, when assembled, form a cuboid on the outside and consist of heat-insulating and / or sound-insulating material, in particular polypropylene. Each of the two shells has a recess 3 on the inside, which together form a shape that corresponds to the outer contours of the pump in the transport position. In some places, the overall recess consisting of two recesses 3 can be made larger in some places than the outer shape of the pump, so that in some places the transport recess is not in contact with the outside of the pump.

Beide Schalen 1,2 bilden an den Innenseiten darüberhinaus jeweils eine weitere Halbausnehmung 4, die zusammen eine Gesamtausnehmung in beiden Schalen bilden, in der die Pumpe in der Montagestellung einliegt. Diese Ausnehmung wird im folgenden Montageausnehmung genannt. Transportausnehmung und Montageausnehmung durchdringen einander, wobei in der Montageausnehmung die Pumpe mit ihrer Läuferachse rechtwinklig zur Transportstellung liegt.Both shells 1, 2 also form a further half-recess 4 on the inner sides, which together form an overall recess in both shells, in which the pump lies in the assembly position. This recess is in the called the following mounting recess. The transport recess and the installation recess penetrate each other, the pump with its rotor axis being at right angles to the transport position in the installation recess.

In der Montagestellung (Fig. 4, Fig. 5) steht die Pumpe mit dem äußeren Bereich 5 des Motors über die Verpackung hinaus, wobei der Motor die vordere Flachseite 6 der vorderen Schale 1 durchdringt. Hierzu ist in der Seite 6 eine entsprechende Ausnehmung 7 vorgesehen, die während des Transports durch einen Einsatz 8 verschlossen ist. Nach der Montage der hinteren Schale 2 und der Pumpe 9 mit ihrem Motor 10 wird aus der vorderen Schale 1 der Einsatz 8 herausgenommen, so daß die vordere Schale 1 auf die Pumpe aufgesetzt werden kann, wie dies in Fig. 5 gezeigt ist. In dieser Stellung steht auch außen ein Klemmenkasten und/oder Elektronikkasten an der Oberseite des Motors zur Bedienung vor.In the assembly position (FIG. 4, FIG. 5), the pump with the outer region 5 of the motor extends beyond the packaging, the motor penetrating the front flat side 6 of the front shell 1. For this purpose, a corresponding recess 7 is provided in page 6, which is closed by an insert 8 during transport. After assembly of the rear shell 2 and the pump 9 with its motor 10, the insert 8 is removed from the front shell 1, so that the front shell 1 can be placed on the pump, as shown in FIG. 5. In this position there is also a terminal box and / or electronics box on the top of the motor for operation.

Ferner bilden die zwei Schalen 1,2 seitliche Öffnungen 12, 13, durch die die Pumpenanschlußstutzen führbar sind und die während des Transports durch Einsätze verschlossen sind.Furthermore, the two shells 1, 2 form lateral openings 12, 13, through which the pump connecting pieces can be guided and which are closed by inserts during transport.
