Definitions
- the invention relates to a multi-stage side channel compressor according to the preamble of claim 1.
- Such a side channel compressor is known from DE-OS 18 17 430.
- a separate cooling system is arranged in this known side channel compressor between the housings of the two compressor stages.
- This cooling system consists of a fan that conveys cooling air between baffles connected to the two housings.
- Such a cooling system requires considerable assembly effort. Even if the baffles are made in one piece with the corresponding housing parts, the fan must still be installed between the two housings.
- the invention has for its object to provide a multi-stage side channel blower of the type described above so that better cooling is achieved with less assembly and material.
- the problem is solved by the features specified in the characterizing part of claim 1.
- the supply of a cooling liquid in the space already present between the housings of the individual compressor stages results in very intensive cooling.
- all that is required is to seal the intermediate space and in each case a corresponding inlet and outlet opening for the cooling liquid.
- the use of the space that is present anyway has the advantage that, despite the good cooling, the overall length of the side channel blower is not must be enlarged. The short length of the shaft of the side channel blower, which is necessary to avoid critical speeds, can thus also be achieved.
- the inlet and outlet openings are provided on the relevant housing in the region of the interrupter separating the inlet and outlet openings of the housing. Since the side channel is omitted in the area of the interrupter, there is sufficient space for the inlet and outlet opening without the overall length of the side channel compressor having to be increased.
- the ventilation required when filling the intermediate space with cooling liquid can be achieved in a simple manner in that the outlet opening is connected either directly or via a ventilation line to the highest point of the intermediate space in relation to the operating position of the compressor.
- a barrier wall separating the supply and return flow of the coolant is provided in the intermediate space.
- the housing shells opposite one another are formed in one piece by adjacent compressor stages and the intermediate space is formed on the one-piece housing part, the result is a cavity which is completely closed except for the openings necessary for the production. Thus, only these openings need to be sealed.
- the housing of these side channel compressors 1 and 2 consist of outer housing shells 3 and 4 and a common inner housing shell 5.
- This inner housing shell 5 is designed so that it forms two complete compressor housings together with the two attached outer housing shells 3 and 4.
- the impellers 21 of the individual compressor stages arranged on a common drive shaft 20 are located in these compressor housings.
- a further inner housing shell is attached to the inner housing shell 5, to which such an inner housing shell or the corresponding outer housing shell 3 or 4 can in turn be attached.
- a space 6 is created between them in a multi-stage side channel compressor by assembling the individual housings.
- This space 6 can be used for cooling the individual compressor stages by means of a cooling liquid.
- the one-piece design of the inner housing shell 5 results in an intermediate space 6 which, except for the ring opening 7 necessary for the production of this housing shell 5, is completely closed in the hub region of the housing shell 5.
- the ring opening 7 is closed by means of a tube piece 10 lying tightly against the hub extensions 8 and 9 of the inner housing shell 5.
- an inlet and outlet opening 12 and 13 are provided on the inner housing shell 5, to which an inlet or outlet line 14 or 15 is connected.
- a vent line 16 leading to the highest point 17 of the space 6 in the installation position of the side channel compressor is also connected to the outlet opening 13.
- the vent line 16 can be omitted if the outlet opening 13 is in the operating position of the side channel compressor itself at the highest point 17 of the space 6.
- a barrier wall 18 is inserted in the intermediate space 6. This barrier wall 18 can be dispensed with if, in the installation position of the side channel compressor corresponding to FIG. 2, the inlet opening 12 is at the bottom and the mouth 19 of the ventilation line 16 in the intermediate space 6 is at the top. In this case, the desired circulation already results.
