Definitions
- the field of the invention are compressors, in particular side channel compressors and impellers therefor.
- a housing and an impeller include a channel. On the impeller blades are mounted, which protrude into the channel, but not completely fill. Viewed in the direction of rotation of the impeller 0, an inlet to the channel is provided in front of an outlet from the channel.
- the channel comprises two areas, one traversed by the blades of the impeller, and the side channel which is not traversed by the blades. Between inlet and outlet a breaker is provided which closes the side channel.
- the effective length of the breaker must be slightly longer than a paddle distance.
- the interface between the side channel and the remainder of the channel is often a plane perpendicular to the axis of rotation of the impeller or a conical surface whose axis coincides with the axis of rotation of the impeller.
- the breaker is intended to minimize the amount of fluid being drawn from the outlet to the inlet.
- FIG. 1 of this document shows a housing which has ribs on the outside.
- a series of labyrinth seals are disclosed for sealing the gap between the impeller and the housing.
- a cost saving is achieved in particular by a structure in which the housing can consist of one piece, namely the housing shell, which houses the side channel.
- a relative to the housing shell sealed lid which can be made plan, reduces the leakage through the outer annular sealing point, protects the impeller from contact and the contact ends in front of the impeller
- a cup-spring-nut system allows the adjustment of the two gap dimensions of the two annular sealing points, so that it is possible to work with higher tolerances during production and the gap losses nevertheless remain within the framework. This is especially true in the production of small ones Side channel compressors important, which must deliver a lower gas flow than the commercial side channel blower and of which one therefore expects a smaller design.
- the cooling of the side channel compressor can be improved in a simple manner by attaching a fan at the end of the motor shaft facing away from the impeller.
- a honeycomb structure on the housing shell of the side channel compressor improves the rigidity of the shell and may additionally act as a cooling plate when the side channel compressor is mounted with the honeycomb structure upwards.
- the honeycomb structure for a given stiffness lowers the weight of the housing shell and the material consumption for the manufacture of the housing shell.
- FIG. 1 shows a section through a side channel compressor with forced convection.
- FIG. 2 is a perspective view of the forced convection side channel compressor shown in FIG. 1;

- a cover 5 is fastened with screws 6 to the housing shell 2 and protects the rotating with more than 10'00 U / min impeller 3 against contact.
- Cover 5 may be tight relative to the housing shell 2. This reduces the permeability of the outer sealing point 32.
- a pressure is formed, which lies between the pressure at the inlet and the pressure at the outlet. If one assumes that the pressure at the inlet corresponds approximately to the ambient pressure, then cover 5 reduces the pressure difference at sealing point 32 shortly before the outlet, which reduces the leakage current accordingly.
- housing shell 2 has an edge 10.
- Housing shell 2 is with the channel, the sealing points, the cooling fins and the inlet and outlet anyway a complicated component.
- housing shell 2 may be equipped with cooling fins 7.
- a fan 9 may be attached to the side facing away from the impeller 3 of the motor shaft.
- One Heilbachsrohr 8 ensures that the promoted by fan 9 air sweeps as completely as possible by cooling fins 7.

- impeller 3 and housing shell 2 are particularly close.
- a dead volume chamber seal 33 is provided by way of example. This has the goal to swirl the airflow flowing through the sealing gap between the impeller 3 and the housing shell 2 as much as possible and thus to make the flow resistance of the sealing gap as large as possible. If possible, there should be no current threads entering the next choke point.
- the air in the channel rotates clockwise.
- the sealing gap runs at sealing point 31 from the channel to the bottom left before the sealing gap widens to Totvolumensch 33.
- the orientation of the seal is chosen so that the highest elevation is directed with respect to the direction of movement of the air molecules.
- the Totvolumenhunt has an approximately circular cross-section, with a smaller circle segment of impeller 3 and a larger circle segment of housing shell 2 is cut. According to the course of the sealing gap, the leakage occurs from the top right in the dead volume chamber, flows through this and meets on the opposite side of the housing shell 2. This and the movement of the impeller 3 relative to the housing shell 2, the air is swirled, which the sealing effect of Totvolumenhunt promotes.
- the Totvolumenschabdichtung 33 is shown only by way of example at the inner sealing points 31. It may alternatively or additionally be provided at the outer sealing points 32 substantially point-symmetrical to the center of the approximately circular channel cross-section.
- Fig. 4 shows a first embodiment for the area Z increases. It recognizes impeller mount 41, which is glued to the motor shaft 40, for example, or fixed by means of a press fit. Disc spring 42 is clamped between a flange of the impeller mount 41 and impeller 3. On its other side impeller 3 is pressed by washer 44 and nut 43 against disc spring 42. By tightening or loosening of nut 43 against Laufradier, e 41 plate spring 42 is pressed more or less together and the sealing gaps between impeller 3 and housing shell 2 reduced bew. Enlarged. The leadership of impeller 3 is mainly determined by the quality of the fit between the impeller 3 and impeller mount 41. Impeller mount 41 and impeller 3 can positively engage with each other. The positive connection can be generated by noses or flats

- the washer is missing.
- a lock nut 46 is provided to unintentionally release nut 43 during operation prevent.
- the impeller 45 has a recess for nut 43 so that impeller 45 can serve as a wrench during assembly.
- This recess can be hexagonal to optimally transfer torque to nut 43.
- the recess may also be rectangular, wherein the short side of the rectangle corresponds to the nut width of the nut and wherein the effect of the recess is then more comparable to a fork wrench.
- the positive connection between nut 43 and impeller 45, together with locknut 46 provides reliable torque transfer from motor shaft 40 to impeller 41 via impeller mount 41, thereby preventing slippage.
- a fit between the impeller mount 41 and impeller 45 is provided.
- FIG. 6 shows the third embodiment for the region Z.
- the central hole in impeller 48 has a fitting 50 in the lower region and a thread 49 in the upper region, which replaces nut 43.
- thread 49 may extend over the entire central bore in impeller 48.

- fan 9 and Vietnamesephilgungsrohr 8 are not mounted. However, have cooling fins 7 notches 14, so that a ventilation tube 8 can be easily infected. Also, the motor shaft projects beyond the motor housing down, so that a fan 9 can be plugged.
- the interesting region X is shown enlarged in FIG.
- Fig. 8 shows the attachment of the motor 4 by means of a swash plate 61 on the housing shell 2. Also in this embodiment impeller 3 is fixed by means of a Laufradability 64, a washer 65 and a nut 66 to the motor shaft 60. A plate spring is unnecessary, since the gap dimensions can be adjusted via adjusting screws 63, but can also be mounted.
- the motor housing is directly on swash plate 61, for example by means of Adhesive or screws attached. Springs 62 press swash plate 61 against adjusting screws 63 and thus suppress play. Swash plate 61, springs 62 and adjusting screws 63 may be referred to as a wobble device.
- swash plate 61 may be missing.

- FIG. 10 another embodiment of a side channel compressor is shown, in which the housing shell 81 is made of an extruded profile.
- Fig. 11 shows an impeller 93 with functional blades 94 and intermediate blades 95.
- the functional blades 94 range from a sealing gap to the breaker zoom.
- the intermediate blades 95 have a considerable distance to the breaker when installed. In one embodiment, its height is 2/3 of the height of the functional blades. The intermediate blades serve to reduce noise.
- the outlet-side edge of the breaker is arranged obliquely opposite to the blades of the impeller. This also serves to reduce noise. It is particularly advantageous if the angle between this edge and the blades of the impeller is selected so that this edge the space between the leading edges of two adjacent blades sweeps.
- the outlet side boundary of the breaker may also be composed of several edges. In the case of two edges this boundary has an arrow shape, in the case of more edges this border is saw-shaped with a multitude of saw teeth. The particularly advantageous length of a blade distance of the edges in the tangential direction is maintained.
- the inlet-side edge of the breaker may be oblique just like the outlet-side edge and composed of several edges. Again, the preferred length in the tangential direction is a blade distance.
- the side channel blower according to the invention is used primarily for the delivery of air, other gases or even fluids in general can be promoted. Due to the low compressibility of liquids, one does not have the problem here that the liquid dragged across the breaker expands in the area of the inlet.
