Definitions
- the invention relates to a liquid ring compressor according to the preamble of claim 1.
- a compressor is known from EP-B 0 392 034.
- Liquid ring compressors are usually only for the promotion of a small additional Amount of liquid designed. In addition, it is usually Amount of liquid to be carried during dimensioning of the compressor not yet known, so the compressor also not specifically for the co-funding of a larger one Amount of liquid can be designed. Is a Liquid ring compressor not for the promotion of a certain amount of liquid designed, then this can in Operation to deteriorate running properties and lead to higher power requirements.
- the invention has for its object a liquid ring compressor of the generic type so that regardless of that in a gas-liquid mixture sucked in by the compressor amount of liquid contained Performance of the compressor is not affected.
- the task is solved by the in the license plate of claim 1 specified features.
- the suction chamber can use the remaining parts of the compressor for a normal Conveying liquid can be designed. The most secluded and soothed liquid can be at the bottom of the suction chamber be sucked off.
- the separation of those contained in the gas-liquid mixture Liquid and its calming necessary for suction is achieved in a simple manner in that with respect to the direction of rotation of the impeller in the downstream of the suction slot Area of the suction chamber as a separating and sedative at least one parallel to the level of Control disc extending, pointing to an adjacent wall and a wall part leaving a passage gap is arranged.
- FIG. 1 denotes the housing of a liquid ring compressor, in which an impeller 2 with its central axis eccentric with respect to the center axis of the compressor housing is staggered.
- the impeller 2 is with its shaft 3 mounted on the front sides of the compressor housing 1
- Side shields 4 rotatably mounted.
- On the side plate 4 is an intake manifold 5 and a pressure nozzle 6 are integrally formed.
- the intake manifold 6 opens into a molded in the side plate 4 Suction chamber 7 and the pressure port 6 accordingly in one Pressure chamber 8. Both chambers are in pressure by one Partition 13 separated from each other.
- a control disk in a known manner 9 inserted, which the suction and pressure chamber 7 and 8 of the side plate 4 spatially opposite the work space 10 of the compressor housing 1 delimits.
- the control disc 9 has one suction and one Print slot 11 and 12 on.
- About the suction slot 11 is Intake chamber 7 with the intake area of the work space 10 and via the pressure slot 12, the pressure chamber 8 with the compression area of the work space 10 connected in terms of flow.
- FIG 2 shows, an im Cross-section of a triangular wall part 14 integrally formed, which projects into the suction chamber 7. For reasons of symmetry is on the partition 13 another in the Pressure chamber 8 projecting wall part is provided.
- the wall part 14 has a geodetically sloping wall side 15 on. Otherwise, the wall part 14 extends parallel to Level of the control disc 9, being between the triangle tip 16 of the wall part 14 and the wall of the compressor housing 1 a passage gap 17 remains free.
- Geodetically below the wall part 14 is a suction opening 18 in the side plate intended.
