Embodiment Construction

[0038] First, refer to figure 1 ,exist figure 1 shows generally an assembled side channel compressor for compressing a gas, comprising an impeller 2 provided with impeller blades 1 and mounted so that it can be positioned sideways about a longitudinal central axis 4 The rotary drive is carried out in the casing 3 of the channel compressor. Thus, the longitudinal center axis 4 forms an axis of rotation.

[0039] The case 3 has a housing 5 and a removable case cover 6, according to figure 1 , the casing 5 and the removable casing cover 6 are aligned together and together surround the impeller 2 , which is arranged in a rotationally fixed manner on the drive shaft 7 and has the impeller blades 1 .

[0040] The single-row impeller 2 is configured in the manner of a disk. The single-row impeller 2 has an impeller hub 8 with a central hub bore 9 . The impeller hub 8 is formed by an inner hub foot 10 adjoining the hub bore 9 radially outwards and an annular hub 11 adjoining said...

Abstract

A side channel compressor for compressing gas comprises a casing (3) and at least one impeller (2), which is arranged in the casing (3) and is rotatably driven about a central axis (4). In addition, the side channel compressor has at least one sealing assembly (38), which is arranged in the casing (3), and has at least one sealing device (47), which seals the casing (3) with the at least one impeller (2 ) and apply a force radially outward to said impeller (2) relative to the central axis (4) so ​​as to keep the at least one gap (59) small. at least one seal assembly (38) further comprising at least one seal retaining device (46) retaining said at least one seal (47) in an axially fixed manner relative to the central axis (4), And there is at least one main retainer (48).

Description

technical field [0001] The present invention relates to a side channel compressor for compressing gases such as air or industrial gases. The side-channel compressor is embodied, for example, as a side-channel fan. Background technique [0002] Side channel compressors are well known from the prior art. The level of efficiency of a side channel compressor depends on the leakage flow that occurs. In order to avoid such leakage flows, corresponding sealing assemblies are used. Unfortunately, seal assemblies are often subject to wear over the life of the side channel compressor, resulting in reduced efficiency levels. In addition, the sealing effect of the sealing assembly is not always satisfactory. Contents of the invention [0003] This patent application claims priority from German patent application DE 10 2016 222 430.1, the content of which is hereby incorporated by reference. [0004] The object of the present invention is to overcome the disadvantages of the prior...
