Definitions
- the invention relates to a gear compressor according to the generic term of Claim 1 as known from US-A-3 355 096.
- oxygen has been mainly produced using so-called classic, multi-stage single-shaft compressor and depending on Compressor of this type compresses final pressure.
- Oxygen can also be compressed by gear compressors, if the following design features are observed. So must the lubricating oil for the bearings and the pumped medium oxygen be carefully separated from one another due to the risk of explosion. That is why in such compressors are those between the bearings and sealing systems (labyrinths) located on the impellers extended and designed as multi-chamber systems. This will however the overhang between the center of gravity of the impeller and the camp center disproportionately large, which is inevitable unfavorable rotor dynamic properties leads.
- the invention has for its object in the compression of oxygen in a geared compressor Keep oxygen and the lubricating oil separate from each other and at the same time favorable rotor dynamic properties for the To achieve gear compressor.
- the geared compressor shown serves to compress Oxygen and contains four compressor stages, of which in Fig. 1 on the left side the first and the third compressor stage 1, 3 are shown, while the second and fourth Compressor stage 2, 4 are only indicated by stub shafts.
- the compressor stages 1 to 4 are integrated oil-lubricated gear driven.
- the gearbox contains a central drive gearwheel within a gear housing 5 6, mesh with the pinion 7.
- Each pinion 7 sits on a rotor shaft 8, the end facing away from the pinion 7
- Impeller 9 of a compressor stage 1 to 4 carries.
- Each rotor shaft 8 is on the side facing away from the impeller 9 in the Gearbox 5 in an oil-lubricated, as a tilting segment bearing trained camp 10 stored.
- the passage of the rotor shaft 8 through the gear housing 5 is on one side by a End cap 11 and on the other side with a Air seal applied shaft seal 12 against the free Sealed atmosphere.
- Each is a free-standing plate 13 Retaining structure is in on two opposite sides a distance from the gear housing 5.
- the plates 13 are via spacers 14 with the gear housing 5 connected and stand together with the gear housing 5 a foundation, not shown. Is between the plates 13 thus an intermediate space through which ambient air flows.
- Each compressor stage 1 to 4 contains an impeller 9, which in one Compressor housing 15 rotates.
- the compressor housing 15 is with provided an inlet part 16 and on the rear side closed by a rear wall 17.
- the rear wall 17 of the Compressor housing 15 is attached to the plate 13 so that the Plates 13 carry the compressor stages 1 to 4.
- each compressor stage 1 to 4 passes through the plate 13 and is here in an additional warehouse 18 stored.
- a hydraulic tilting segment bearing can be used as a bearing be used with an oxygen compatible Lubricants e.g. B. water is lubricated.
- the additional bearing 18 can also be designed as a magnetic bearing be.
- Such magnetic bearings are known. You lead the wave by means of controlled magnetic fields. Because of these magnetic bearings Rotor shaft 8 guided precisely and self-balancing.
- This auxiliary warehouse is in the inlet part 16 of the compressor housing 15 is arranged.
- the auxiliary camp exists from a conical catch bearing 19, which has a conical bearing ring 20 contains, is supported on rollers 21 and a conical Section of the hub 22 of the impeller 9 surrounds.
- the conical Bearing ring 20 of the backup bearing 19 is by means of a Electromagnet 23 against the force of a spring 24 in one Spaced from the hub 22. If the The magnet system of the magnetic bearing becomes the electromagnet 23 ineffective, and the spring 24 presses the conical bearing ring 20th against the hub 22, whereby the impeller 9 is guided without play and can leak safely.
- the rotor shaft 8 is to the outside atmosphere inside the rear wall 17 of the compressor housing 15 by means of a short shaft seal 25 sealed, which as ceramic, dry, gas lubricated Floating ring seal is formed.
- the leakage oxygen can passed together with sealing air into an exhaust air system will. He could also easily go to the machine shop escape.
- rotors with larger ones Seal diameters are compared to oil-lubricated bearings, through this design principle rotors with larger ones Seal diameters.
- Rotor shaft 8 gives favorable leverage in the Oil-lubricated bearings 10.
- the rotor shaft 8, as shown in Fig. 3, also in another oil-lubricated bearing 26 may be mounted on the the other side of the pinion 7 in the gear housing 5 is arranged.
- the additional bearing has 18th especially when using a magnetic bearing Function of a guide and damping bearing.
- the diameter of the rotor shaft 8 enlarges what by using a ceramic, dry gas-lubricated floating ring seal as shaft seal 25 is favored.
- the slight overhang of the Center of gravity and the enlarged diameter of the Rotor shaft 8 reduce the susceptibility to vibration of the Impeller 9, so that larger vibration amplitudes avoided and a smooth run is achieved.
- the great Space between the lubricating oil containing ambient air leading gear housing 5 and the oxygen-promoting Compressor stages 1 to 4 ensure a clean separation of Lube oil and oxygen.
- the invention is therefore also for the compression of gases other than oxygen can be used if the compressed gas is absolutely free of oil is required in the range of a few ppm.
