Definitions
- the invention relates to a liquid ring machine.
- Such machines are known (DE-A-43 05 424). Such machines have a tubular machine housing which surrounds the impeller of the machine, by means of which the operating fluid is set in rotation. The rotating liquid ring generated by the impeller flows along the inner wall. The resulting flow losses depend on the nature of the inner surface of the machine housing. During the operating time of a liquid ring machine, the inner surface of the machine housing can change due to corrosion in such a way that the flow conditions deteriorate.
- the invention is based on the object of permanently deteriorating a liquid ring machine
- the machine housing is covered at least on its inner circumference with a layer which has a surface with a low roughness depth.
- a layer which has a surface with a low roughness depth.
- An improvement in the pressure and speed curve in the liquid ring is achieved in that the surface of the layer is at least partially structured.
- Such The measure is particularly advantageous in the case of changing flow velocities on the inner surface of the housing.
- the layer consists of an elastic material.
- a further improvement in the flow conditions results from the fact that the interior of the machine housing is completely coated.
- Rubber has proven to be particularly advantageous as a coating material. This material also offers corrosion protection.
- the rubber layer has a diamond-shaped structure on the side facing the working space of the liquid ring machine.
- Such a structure has proven to be very low loss. It is again favorable if the diamonds point with their large axis in the direction of flow of the liquid ring of the liquid ring machine.
- 1 shows a machine housing in longitudinal section.
- 2 shows a rubber layer with a structured surface.
- the machine housing is axially divided by an intermediate wall 2 arranged in its axial center.
- a rubber layer 4 is applied to the inner circumference 3 of the machine housing 1.
- the intermediate wall 2 is also covered with a rubber layer 4.
- the rubber layer 4 has a diamond-shaped structured surface 5, as shown in FIG. 2. With a surface 5 structured in this way, the rubber layer 4 is attached in the machine housing 1 in such a way that the individual diamonds 6 with their large axes point in the direction of flow indicated by an arrow 7 of the liquid ring rotating in the machine housing 1.
