Definitions
- the invention relates to a side channel compressor with an annular impeller housing having a rotatable in it stored impeller encloses and with a Heilansaug- and an air outlet is provided.
- the impeller housing This single-stage side channel blower is double-shelled formed, wherein the two housing shells different are designed.
- a the actual "housing" forming Housing shell is with the respective molded Air intake and air outlet and with a bearing support provided for a rolling bearing, in which one the impeller bearing shaft is mounted.
- the other housing shell is formed in the manner of a "lid” along a perpendicular to the impeller shaft axis extending parting plane sealed is placed. Both housing shells are by axially arranged around distributed bolts braced together.
- With the air intake and the air outlet are connecting elements in the form of silencers and the like, while connected to the Air intake and the air outlet nozzle supporting housing shell a flanged the impeller shaft driving electric motor is.
- each ring compressor can also be used to generate desired air volumes be switched in parallel or in series.
- Parallel or series connection requires but own suitably designed collection and / or branch lines, laid outside the compressor assembly and with the air outlet of each ring compressor need to be connected.
- the task is based on a side channel compressor to create that compared to the state of the art without large additional operational effort more versatile is.
- the new side channel blower is the impeller housing provided with a continuous channel, which is in Axial direction from one side of the housing to the opposite Housing side extends. Because the channel is inside the Impeller housing is arranged, it requires no magnification the housing dimensions. He can for a variety of purposes may be used, in which e.g. it depends on one Fluid flow independent of that of the side channel compressor funded gas or air flow through the housing axially by pass. For example, it is possible to use the channel for Passing a cooling medium through the impeller housing to use to dissipate the resulting heat of compression. For this it is expedient that the channel in the area between the air supply and the air outlet, i.e. in the area of the so-called breaker between them two connecting pieces is arranged.
- Impeller housings In the multi-stage design of a side channel blower with at least two axially interconnected Impeller housings, each containing its own impeller, are the channels of the axially adjacent one another Impeller housing to a common, through the impeller housing continuous axial channel connected together.
- This channel allows a return of the compressed gas or the compressed air through the housing.
- the necessary Gas or air deflection can easily be done by deflecting on an impeller housing are attached, with the air outlet of this Impeller housing in gas or air connection or in general in fluid communication.
- the deflection can also several compressor stages eg. be switched one behind the other.
- the channel can also be through Partitions in longitudinally parallel to each other Split sub-channels, if this is the respective Purpose appears necessary.
- the side channel compressor shown in Figs. 1 and 2 has a substantially annular impeller housing 1, which consists of two identical housing shells 2 and encloses a shown in Fig. 4 at 3 impeller.

- the two impeller housing 1 forming Housing shells 2 are identical.
- Each of the housing shells 2 has a side channel receiving the impeller 3 5 on, covering most of the circumference extends and a molded air inlet 6 with a molded air outlet 7 connects. Between the air inlet nozzle 6 and the air outlet 7 is a locking piece 8 is arranged, as in side channel compressors known per se.
- the air intake 6 and the air outlet 7 are in a common housing part 9 formed integrally on the housing shell. 2 is formed on both sides and a flat, perpendicular to the impeller axis 10 extending fitting surface 11, and 11a wearing.
- a through-channel 12 formed over the entire axial length of the Housing shell 2 extends and in the two opposite and mutually parallel mating surfaces 11, 11a empties.
- the passageway 12 is in the region of the locking piece 8 arranged and is not with the side channel 5 in Connection.
- the part-annular side channel 5 extends around a disc-shaped hub part 13 of the housing shell 2, on which a centric bearing housing 14 is formed, the for receiving a rolling bearing 16 for the impeller 3 bearing Shaft 10 is determined (see Fig. 4).
- the rolling bearing 16 is by a screwed bearing cap 17 to the outside too closed.
- the bearing housing 14 of a tubular, substantially cylindrical Ring flange 19 surrounded, on its outer end face a flat mating surface 20 carries, parallel to the Matching surface 11 is aligned with the housing part 9 and with this lies in a common plane.
- the electric motor 4 flanged while on the Electric motor 4 opposite impeller housing outside on the annular flange 19 of the corresponding housing shell. 2 a lid 21, screwed sealed against the mating surface 20 is.
- a support block 22 which is located between two cooling fins 23, the the Side channel 5 containing housing shell part outside in the For example, surrounded from Fig. 1 apparent manner.
- the support block 22 protrudes axially slightly above the cooling fins 23 and carries on its outside a flat mating surface 24, the with the mating surface 11 of the housing part 9 and the mating surface 20 of the annular flange 19 lies in a common plane.
- Flange 18 carries on its side facing away from the annular flange 19 Side a flat plane 25, which is perpendicular to the Impeller axis 100 runs and in a plane with the associated Mating surface 11 of the housing part 9 is located.
