Definitions

the invention relates to a side channel compressor according to the preamble of the claim 1.
the invention is therefore based on the object, the side channel compressor Elimination of the disadvantages outlined so that improved Efficiency an increase in volume flow with a uniform Pressure increase in the side channel results.
the side channel compressor designed according to the invention has a modified one Cross section of the side channel, in such a way that the cross section of the side channel tapers from the suction side towards the pressure side.
the structural design is expediently provided in such a way that the suction side has a larger cross section of the side channel, and preferably by at least a factor of 1.15 compared to the pressure side of the side channel, and that this cross section of the side channel towards the pressure side rejuvenated.
cross section of the side channel is continuous or continuously rejuvenated.
this advantageous embodiment results from this embodiment according to the invention achieved that the enlarged channel cross-section in the suction area improved Expansion of the gas ensures that the pressure side through the interrupter entry. This means that a vacuum can also be achieved at a lower level and the suction power increases.
the cross-sectional taper of the side channel is 20-40%.
the side channel Housing cover an inward-pointing flow guide edge for the pumped Media arranged.
This flow guide edge is in the form of a tapered Rib formed, advantageously the cross section of the flow leading edge adapted to the tapering cross section of the side channel is.
the flow guide edge can be formed in one piece with the wall of the side channel be. Instead, the flow leading edge can also be on a separate Guide ring formed in the side channel at the corresponding desired Place used on the inner wall or attached there.
a side channel compressor has impeller equipped with blades, which is used to compress gases in one Housing is rotatable.
the housing is provided with a cover 1, which has a gas inlet 2 and a Has gas outlet 3 and, as can be clearly seen from Fig. 2, on the impeller facing side a side channel 4 limited.
the cross section of the side channel 4 is bowl-shaped and designed such that he from the gas inlet 2 (suction side) towards the gas outlet 3 (pressure side) rejuvenated.
the tapering of the side channel cross section takes place in the illustrated Embodiment continuously or continuously.
the cross-sectional taper is in the embodiment shown such that the cross section of the side channel 4 at the point D - D according to 1 in the manner shown in FIG. 6 is 130%. Tapered from here then the cross section of the side channel 4 steadily over 122% of the Interface C - C according to FIG. 1 (see FIG. 5) and over 107% at the interface B - B according to FIG. 1 (see FIG. 4) except for 100% at the interface A - A or near the gas outlet 3 (see Fig. 3).
a flow guide edge 5 which tapers conically is formed and points inward in the manner shown.
This flow leading edge 5 is formed in one piece with the wall of the side channel 4 and serves for the corresponding redirection of the flow of the media to be conveyed the outer area of the side channel 4. This will result in a better deflection the flow, which results in an efficiency improvement of 5 to 9%.
the formation of the flow leading edge 5 over the entire circumference of the side channel 4 is selected such that the cross section of the flow guide edge 5 on the tapering cross section of the side channel 4 is adapted.
the flow guide edge 5 is integrally formed with the wall of the side channel 4, is in the modified embodiment according to FIGS. 8 and 9 on the flow guide edge 5 a separate guide ring 6 is provided, which in the manner shown in FIG. 8 is formed and inserted into the interior of the side channel 4 or there is attached that the flow guide edge 5 in the same manner as in the previously described Embodiment according to FIG. 7 shows inwards.
This one too Embodiment becomes the same effect in efficiency improvement as achieved in the embodiment of FIG. 7.
FIGS. 10 and 11, 12 serve as a supplementary explanation the operation of a side channel blower and show schematically in Fig. 10 a side channel blower with a single ring impeller 7 in radial Type with a semicircular cross section of the side channel 4, wherein the side channel is formed in the housing or cover 1.
the in Fig. 10 The arrows shown represent the flow of the media to be pumped, in such a way that the open impeller 7 with its blades to be promoted Medium pushes out of the impeller 7 and this against the wall of the in the cover 1 side channel 4 presses. From there the flow becomes like this deflected that the medium to be conveyed is pressed into the impeller 7 again.
a so-called double-flow side channel compressor is provided.
the impeller 7 is formed with a double blade ring, one blade assembly from the other blade assembly is averted.
Each blade ring unit is a side channel 4, which on one Lid is arranged, assigned.
FIG. 13 shows a development of the side channel 4 on the suction or pressure side can be seen.
the cross section of the side channel 4 at the gas inlet 2 is separated from the gas outlet 3 by an interrupter web 8, opposite the Cross section near the gas outlet expanded by the amount that by the hatched area 9 is marked.
