Definitions
- the invention relates to a container out of concrete for vacuum applications.
- An advantageous embodiment of the invention is characterized in that the container out of concrete is arranged in such a way to balance rotors in its interior under vacuum conditions. Therefore, rotors may be balanced economically and safely under vacuum conditions.
- a further advantageous embodiment of the invention is characterized in that the rotors to be balanced are turbines or compressors which are provided with blades.
- the rotors may be constructed such that the blades are attached themselves to the rotor or such that the rotors carry bladed impellers.
- turbines or compressors may be economically and safely balanced without larger ventilation losses leading to an unacceptable heating of the rotor and without the need for extremely high driving power.
- a further advantageous embodiment of the invention is characterized in that the rotors to be balanced are constructed to be used in motors or generators and comprise electric coils.
- rotors designed for the use in motors or generators may be balanced in a particular economic way in vacuum containers without parts of the coils which become disintegrated from the rotor at high rotational speeds, endangering the environment.
- This object is achieved in that a container out of concrete is provided inside or outside with a coating which exhibits an adhesive tensile strength which corresponds at least to an external pressure load of 1 bar.
- Such a container may be manufactured economically and can be handled easily since no additional vacuum envelope, for example out of steel, has to be installed inside or outside of such a container out of concrete.
- such a container uses the available space particularly efficiently since no additional space for an additional vacuum envelope is needed neither inside nor outside of the container.
- the container is formed out of steel reinforced concrete. This enables a stable but never the less economic and time-saving production in particular with larger containers.
- a further advantageous embodiment of the invention is characterized in that the coating comprises a suitable plastics material, in particular a suitable epoxy resin.
- a suitable plastics material in particular a suitable epoxy resin.
- Plastic materials or epoxy resins, respectively, having the required air tightness and adhesion tensile strength, are low priced and may be formed into a coating of a container having an arbitrary shape, particularly simple prior to curing.
- the epoxy resin is a two-component epoxy resin.
- the container comprises suction stubs and hatches whereby the container can be evacuated particularly easily and the installations necessary for carrying out the processes under vacuum, may be placed particularly easily into the interior of the container.
- a further advantageous embodiment of the invention is characterized in that the suction stubs and hatches are cast into the concrete by means of suitable flange adapters. Thereby, the suction stubs and hatches may be opened, closed, maintained and, if necessary, exchanged in a particularly simple way without damaging the concrete or the vacuum-tight coating.
- a further advantageous embodiment of the invention is characterized in that the container is configured to be hermetically sealed and to be evacuated by means of a vacuum pump installation to a desired end pressure. Because of this advantageous arrangement, experiments and processes under vacuum conditions may be carried out in a simple and economic way in the container of the invention.
- FIG. 1 depicts a sectional view of a preferred embodiment of the concrete container of the subject invention.
- FIG. 1 shows a sectional view through a container 1 according to the invention.
- a rotation axis 7 extends horizontally in the middle of the figure from left to right.
- the embodiment of the container 1 of the invention shown in FIG. 1 is rotationally symmetric about the rotation axis 7 .
- FIG. 1 shows a hatch 5 which is connected to a steel flange 4 .
- the hatch comprises a circular groove 5 a , into which a sealing ring 11 is inserted.
- sealing rings 11 are known to persons of ordinary skill in the art and are made, for example, out of rubber or cacutchouc. This sealing ring 11 hermetically seals the connection between the hatch 5 and the steel flange 4 .
- the steel flange 4 is followed by a glue layer 10 to the right hand side which is followed by the concrete envelope 2 .
- the glue layer connects the steel flange 4 air-tightly to the concrete envelope 2 .
- the steel flange 4 is air-tightly cast into the concrete envelope without the use of a glue layer 10 .
- the concrete envelope 2 comprises a rotationally symmetric interior space 8 around the rotation axis 7 .
- the concrete envelope 2 is completely covered with a coating 3 on its side facing the interior space 8 .
- the coating 3 exhibits an adhesive tensile strength which corresponds at least to an outer pressure load of 1 bar.
- the coating 3 is applied to the outer walls 9 a , 9 b of the concrete envelope.
- the coating 3 consists of a suitable plastics material, more particularly, a suitable epoxy resin.
- a suitable plastics material more particularly, a suitable epoxy resin.
- Such plastic materials are economic, very durable and can be adapted into different shapes of the interior space and processed in a particular easy way.
- a steel flange 6 is air-tightly cast into the concrete envelope 2 .
- a vacuum pump not shown in FIG. 1
- the steel flange 6 is fixed air-tightly to the concrete envelope 2 by means of a glue layer 10 .
- the balancing apparatus for balancing of rotors is placed into the container.
- Rotors for balancing may include but are not limited to turbines or compressors, with blades or motors or generators having electric coils.
