Abstract

The insulation shell (1) has a high reflective shell inner wall surface (2). The inner faces (12) are mirror coated and are produced by aluminium high vacuum vapour deposition process. Alternatively the inner faces are chromed and polished and are of a silver or gold colour. The insulation shell is divided into two half shells (1a,1b) bound together by a film joint (11). The shell and the pump outer side have an air passage (4) between for insulating the pump.

Description

Die Erfindung betrifft eine Isolierschale, die eine Pumpe insbesondere eine Kreiselpumpe, einen Motor oder eine Armatur außen umgibt.The invention relates to an insulating shell, which is a pump especially a centrifugal pump, an engine or a Armature surrounds outside.

Aus den deutschen Offenlegungsschriften 27 51 469 und 41 18 057 ist es bekannt, eine Pumpe außen mit einer gehäuseähnlichen Verkleidung zu umgeben, die schall- und wärmedämmend wirkt. Hierbei sind verhältnismäßig dicke Wandungen erforderlich, um einen ausreichend hohen Dämmgrad zu erreichen. Dies ist platzraubend und kostspielig.From German Offenlegungsschriften 27 51 469 and 41 18 057 it is known to use a pump outside to surround housing-like cladding, the sound and has a heat-insulating effect. Here are relatively thick Walls required to be sufficiently high Achieve degree of insulation. This is bulky and expensive.

Aufgabe der Erfindung ist es, eine Isolierschale der eingangs genannten Art so zu verbessern, daß sie bei geringem Herstellungs- und Montageaufwand und bei ausreichender Dämmwirkung wenig Platz benötigt. The object of the invention is to provide an insulating shell type mentioned so that they improve low manufacturing and assembly costs and sufficient insulation required little space.  

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Flächen der Schaleninnenwände hochreflektierend sind.This object is achieved in that the surfaces of the inner shell walls highly reflective are.

Bei einer solchen Isolierschale wird die vom Aggregat abgegebene Wärmestrahlung durch die reflektierende Innenfläche zum Aggregat zurückgeworfen, so daß ein hoher Wärmedämmgrad erreicht wird, ohne dickwandige Isolierschalen aus wärmedämmmenden Material verwenden zu müssen. Es kann also die Wand der Isolierschale verhältnismäßig dünn ausgeführt sein und/oder aus einem weniger stark isolierenden Material gefertigt werden.With such an insulating shell, the one from the unit emitted heat radiation by the reflective Thrown back inner surface to the aggregate, so that a high Thermal insulation level is achieved without thick-walled Use insulating shells made of heat-insulating material to have to. So it can be the wall of the insulating shell be made relatively thin and / or from one less insulating material can be made.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen aufgeführt.Advantageous embodiments of the invention are in the Subclaims listed.

Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen dargestellt und wird im folgenden näher beschrieben. Es zeigen:An embodiment of the invention is in the Drawings shown and will be described in more detail below described. Show it:

Fig. 1 Einen axialen Schnitt durch eine Pumpe mit außen aufgesetzter Isolierschale. Fig. 1 An axial section through a pump with an outer insulating shell.

Fig. 2 Eine Seitenansicht der Pumpe und Fig. 2 is a side view of the pump and

Fig. 3 eine Innenansicht der abgenommenen aufgeklappten Isolierschale. Fig. 3 is an inside view of the removed opened insulating shell.

Die Isolierschale (Verkleidung, Schutzhülle) 1 hat die Form einer äußeren zweischaligen Verpackung, die um das Pumpengehäuse 2 eines Motorenpumpenaggregats 3 insbesondere einer Kreiselpumpe gelegt ist. Zwischen der Gehäuseaußenseite und der Schale 1 ist ein die Pumpe umgebender Zwischenraum 4, dessen Luftschicht isolierend wirkt. Hierbei weist die Schalenwand auf einer Seitenfläche eine große Öffnung 5 auf, durch die das Motorengehäuse 6 nach außen hin durchtritt. Ferner sind mindestens zwei weitere Öffnungen 7, 8 vorgesehen, durch die Anschlußleitungen oder Pumpenstutzen 9, 10 hindurchtreten.The insulating shell (cladding, protective cover) 1 has the shape of an outer double-shell packaging, which is placed around the pump housing 2 of a motor pump unit 3, in particular a centrifugal pump. Between the outside of the housing and the shell 1 is an intermediate space 4 surrounding the pump, the air layer of which has an insulating effect. Here, the shell wall has a large opening 5 on one side surface, through which the motor housing 6 passes to the outside. Furthermore, at least two further openings 7 , 8 are provided through which connecting lines or pump connections 9 , 10 pass.

Die beiden Schalen 1a, 1b sind durch ein Filmscharnier 11 miteinander verbunden, so daß sie einstückig hergestellt werden und damit einteilig sind. Auf der dem Scharnier 11 gegenüberliegenden Seite werden die Schalen durch einen Schnappverschluß miteinander lösbar verbunden.The two shells 1 a, 1 b are connected to one another by a film hinge 11 , so that they are produced in one piece and are therefore in one piece. On the side opposite the hinge 11 , the shells are detachably connected to one another by a snap lock.

Die Wandung beider Isolierschalen besteht aus Kunststoff insbesondere aus Polypropylen mit einer Wandstärke von 1,2 bis 3 mm, insbesondere 1,5 bis 2,5 mm.The wall of both insulating shells is made of plastic in particular made of polypropylene with a wall thickness of 1.2 to 3 mm, in particular 1.5 to 2.5 mm.

Die Innenseiten bzw. Innenflächen 12 beider Schalen 1a, 1b sind verspiegelt insbesondere verchromt oder Aluminium-Hochvakuum-bedampft, wobei die Flächen 12 entweder hochglänzend oder matt ausgeführt sind. Sie können hierbei auch farbig, das heißt nicht nur silbern, sondern auch goldfarben sein oder eine andere Färbung besitzen, soweit die Innenflächen hochreflektierend bleiben.The inner sides or inner surfaces 12 of both shells 1 a, 1 b are mirrored, in particular chrome-plated or aluminum-vacuum-vapor-deposited, the surfaces 12 being either high-gloss or matt. They can also be colored, meaning not only silver, but also gold-colored or have a different color, provided the inner surfaces remain highly reflective.
