Abstract
Description
- The invention relates to a device which is arranged to be used as a generator.
- According to the invention the rotor comprises a number of blades. The blades are spiral-shaped and their effective surface area increases in the direction in which the water is guided through the device.
- Preferably the rotor comprises a cylindrical casing, which casing lies sealingly against the inner wall of the tubular housing.
- In a preferred embodiment of the device according to the invention a number of rotors are arranged successively in the tubular housing as seen in axial direction.
- In yet another embodiment of the device according to the invention the spiral-shaped blades taper in the direction in which the water is guided through the device from the hub toward the casing.
- In yet another embodiment of the device according to the invention the spiral-shaped blades taper in the direction in which the water is guided through the device from the casing toward the hub.
- The device according to the invention can further comprise a generator coupled to the pump rotor. It hereby becomes possible to generate energy, for instance by having water flow from a higher level to a lower level.
- These and other features of the invention are further elucidated with reference to the accompanying figures.
-
Figure 1 shows a pumping station having therein a sinking pump according to the invention. -
Figures 2-4 show a first embodiment of a pump rotor for a sinking pump. -
Figures 5-7 show a second embodiment of a pump rotor. -
Figure 1 shows a pumping station 1. This pumping station 1 has asinking pump 2. Sinkingpump 2pumps surface water 3 from a lower level over a dike body 4 to surface water 5 at a higher level. The sinking pump can also be used as generator, for instance in the embodiment according tofigure 1 . Motor 9 must here be replaced with a generator. Surface water 5 can then be guided from the higher level, through the sinking pump tolower level 3.Pump rotor 7 is herein driven, and thereby the generator. - A hybrid form with a motor 9 and a generator is also possible.
-
Sinking pump 2 has atubular housing 6 in which threepump rotors 7 are arranged on anaxial drive shaft 8.Drive shaft 8 is driven by a motor 9. -
Figure 2 shows a perspective view of apump rotor 7 for asinking pump 2 according to the invention.Pump rotor 7 has ahub 10 on which a number ofblades 11 are arranged. Arranged around theseblades 11 is acylindrical casing 12 which is attached to the blades. Thiscylindrical casing 12 has a diameter which is substantially equal to the internal diameter oftubular housing 6 ofsinking pump 2. A seal can optionally be provided betweencylindrical casing 12 andtubular housing 6.Figure 3 shows a front view ofpump rotor 7, i.e in pumping direction P, where the water first comes into contact withpump rotor 7. As can be seen,blade 11 starts fromhub 10 and then tapers spirally to the rear side ofpump rotor 7.Figure 4 shows the view in pumping direction P on the rear side ofpump rotor 7. It will be apparent that the effective surface area ofblades 11 increases fromhub 10 towardcasing 12. -
Figures 5-7 show a second embodiment of apump rotor 13. Also present here is ahub 14 on whichblades 15 are arranged. The blades are enclosed by acylindrical casing 16. As shown clearly infigure 6 and figure 5 ,blades 15 are spiral-shaped and taper fromcasing 16 tohub 14. As shown infigure 7 , the surface area ofblades 15 increases here in the pumping direction P.
