Definitions

  • the invention relates to a side channel compressor according to the preamble of claim 1.
  • a sealing tape is inserted into a groove of the housing cover which runs transversely to the plane of the gap between the impeller and the housing.
  • This sealing tape can be brought into position by the impeller itself when the side channel blower is installed.
  • the sealing tape is then fixed in this position in various ways, including by an adhesive or sealing compound.
  • the adhesive or sealing compound is introduced into the groove via corresponding openings which are accessible from the outside. Part of the mass can emerge from the groove and stick to the impeller, blocking it and preventing the compressor from starting.
  • the connection of the adhesive or sealing compound can come loose from the smooth wall surface of the sealing tape in the course of the operating time of the side channel compressor.
  • the invention is based on the object of developing a side channel compressor of the generic type in such a way that impairment of the functionality of the side channel compressor by a sealing tape attached to the housing is largely excluded.
  • groove extensions are designed as sack-like extensions accessible from the inside of the housing parts, then the mass can only be introduced into this extension from the inside of the housing and the emergence of the mass from these extensions can thus be observed and prevented accordingly.
  • the interlock between the mass and the sealing tape is most easily achieved by means of depressions provided on the sealing tape, into which the mass penetrates, or by elevations on the sealing tape which are embedded by the mass.
  • a material strip consisting of Teflon can be provided with particular advantage as the sealing tape.
  • FIG. 1 shows a sealing arrangement in a side channel compressor with an unsecured section of the sealing tape
  • FIG. 2 shows a section designed for fastening the sealing tape
  • FIG. 3 shows the section shown in FIG. 2 after the introduction of a solidifying mass.
  • the impeller 2 has, in a known manner, a base ring 5 which is loaded with conveyor 3 and carried by the hub 4 of the impeller 2.
  • a side channel 6 is formed on the housing half 1.
  • the housing of the side channel compressor is completed by a further housing half, which is not shown in the drawing and corresponds to the housing half 1. Depending on the function, there is a gap 7 between the housing halves and the impeller 2.
  • this gap 7 extends over the entire circumference of the impeller and the housing, a flow from the region of higher pressure to the region of lower pressure occurs in a side channel compressor. This flow reduces the delivery volume and thus the efficiency of the side channel blower. In order to prevent such a leakage flow as much as possible, the gap 7 is sealed accordingly with the aid of a sealing arrangement.
  • This sealing arrangement consists of a sealing tape 8, which is inserted into a circumferential groove 9 formed in the respective housing half 1 relative to the base ring 5 of the impeller 2.
  • the sealing tape 8 is held by means of a mass 10 introduced into the circumferential groove 9 at some points on the circumference of the circumferential groove 9.
  • This mass 10 has the property of only solidifying to a certain degree but not hardening, ie the mass has solidified state still has a certain elasticity.
  • bag-like extensions 11 are provided in the area of the circulation groove 9 at the corresponding points. The opening side 12 of these extensions 11 lies on the inner side of the respective housing half 1.
  • the mass 10 can only be introduced into the circumferential groove 9 from here, so that the mass 10 emerges from the circumferential groove 9 or the bag-like extension 11 is noticed and any escaped mass 10 can be removed.
  • Bores 13 are provided in the sealing tape 8 and are arranged in the sealing tape 8 such that they come to rest in a bag-like extension 11 when the sealing tape 8 is inserted into the circumferential groove 9.
  • part of the mass 10 penetrates into the bores 13 and at least partially fills them out. This results in a positive connection between the mass 10 and the sealing tape 8, so that this is secured by the mass 10 in the circumferential groove 9.
  • the sealing tape 8 Before the assembly of the housing half 1 with the impeller 2, the sealing tape 8 is inserted into the circumferential groove 9 and the mass 10 is introduced into the bag-like extensions 11. Since the mass 10 is initially still soft, when the housing halves 1 are assembled with the impeller 2, the sealing tape 8 is pressed accordingly into the circumferential groove 9 by the base ring 5 of the impeller 2 abutting against it. The sealing tape 8 thus lies snugly against the base ring 5. The sealing tape 8 is held in this optimal sealing position by the mass 10 gradually becoming solid.

Abstract

L'invention concerne un compresseur de canal latéral dans lequel l'espace (7) situé entre la roue mobile (2) et les parties du boîtier (1) entourant ladite roue mobile (2) est rendu étanche à l'aide d'une bande d'étanchéité (8) introduite dans une rainure périphérique (9) prévue dans les zones correspondantes des parois des parties du boîtier (1). Tout risque d'éventuelle altération de la fiabilité de fonctionnement du compresseur de canal latéral, due à la bande d'étanchéité appliquée sur le boîtier, est grandement exclu, dans la mesure où ladite bande d'étanchéité (8) est maintenue par une matière durcissante, introduite dans plusieurs parties évasées (11) de la rainure, prévues en plusieurs points répartis sur le pourtour de la rainure périphérique (9), et se rétractant par liaison de forme avec la bande d'étanchéité (8).
