Definitions
- the invention relates to a centrifugal pump, in particular for the pumping of a mixture of substances possibly including stones and/or pebbles, comprising:
- a centrifugal pump of this type is known.
- the rotor rotates about the axial rotation axis.
- the mass to be pumped is forced radially outward into the pump housing under the influence of centrifugal forces.
- Said mass is then entrained in the circumferential direction of the pump housing toward the tangential outlet spout of the pump housing.
- the junction between the inner wall of the tangential outlet and the inside of the circumferential wall of the housing defines what is known as a cutwater.
- the pumped mass which, after leaving the rotor, is entrained in the circumferential direction of the housing flows largely out of the tangential outlet of the housing.
- a small amount of the entrained mass recirculates, i.e. flows along the cutwater back into the pump housing.
- Said centrifugal pump can be used in dredging operations. If the centrifugal pump is located on board a dredging ship, such as a cutter suction dredger, the centrifugal pump has to fetch a loose mixture of substances, possibly including stones and/or pebbles, from the sea floor. The pump must have sufficient suction capacity to do this. Said mixture of substances, possibly including stones and/or pebbles, then flows through the centrifugal substances, possibly including stones and/or pebbles, then flows through the centrifugal pump. In order to prevent blockage, said stones and/or pebbles have to be able to pass through the pump. A wide pump having few blades is suitable for this purpose. However, by widening the pump and reducing the number of blades, the suction characteristics are adversely affected.
- US 2005/0045757 which is considered the closest prior art to the subject-matter of claim 1, discloses a centrifugal pump of the chopper type, which is configured to process solid waste materials such as medical waste, municipal waste and food-processing waste.
- the chopper pump has an impeller that is structured to contact a cutting element positioned adjacent the vanes of the impeller to exert a cutting of chopping action on the solid waste material entering the pump.
- An object of the invention is to provide an improved centrifugal pump.
- this object is achieved in that the ratio between the spherical diameter Bol and the suction diameter D 2 is greater than 0.43, and the ratio between the width B w of the rotor and the suction diameter D z is greater than 0.43, and the ratio between the external diameter D w of the rotor and the suction diameter D z is between 2.3 and 2.5.
- the centrifugal pump according to the invention has a special hydraulic configuration.
- the pump has a larger spherical passage and better suction characteristics than known pumps having a comparable suction diameter.
- the centrifugal pump according to the invention is accordingly suitable for conveying very coarse materials, while the risk of blockage is minimal.
- the ratio between the spherical diameter Bol and the suction diameter D z is approximately 0.5.
- the ratio between the width B w of the rotor and the suction diameter D z is approximately 0.5
- the ratio between the external diameter D w of the rotor and the suction diameter D z is approximately 2.4.
- the spout-shaped outlet of the pump housing has a narrowest passage with a throat diameter D k , the ratio between the throat diameter D k of the spout-shaped outlet and the suction diameter D z being between 0.5 and 0.7. Said ratio between the throat diameter D k of the spout-shaped outlet and the suction diameter D z is, for example, approximately 0.68.
- the spout-shaped outlet may, at the head end thereof, define a press diameter D p , the ratio between the press diameter D p and the suction diameter D z being greater than 0.7 or 0.75.
- the invention also relates to the use of a centrifugal pump as described above.
- the specific rotational speed of the pump is, for example, between 0.05 and 0.12. For example: if the rotational speed of the rotor is 302 revolutions per minute, the flow rate 4.4 m 3 /s and the pressure differential 610 kPa, then the specific rotational speed is 0.086.
- the centrifugal pump according to the invention is denoted in its entirety in figures 1 and 2 by reference numeral 1.
- the centrifugal pump 1 comprises a pump housing 2 shaped like a volute (spiral casing).
- the pump housing 2 has a circumferential wall 3 and a spout-shaped outlet 5 attached tangentially to the circumferential wall 3 of the pump housing 2.
- the junction between the inner surface of the tangential outlet 5 and the inner surface of the circumferential wall 3 of the pump housing 2 defines what is known as a cutwater 4.
- the pump housing 2 also has an axial inlet 6.
- a rotor 7 is attached in the pump housing 2 such that it may rotate about an axial rotation axis A.
- the rotor 7 has a central boss 9 which may be fastened to a drive shaft (not wall for delimiting the flow within the rotor 7.
- the rotor has a suction shield 12 which defines a second wall for delimiting the flow within the rotor 7.
- the suction shield 12 has an axial supply 14 which is aligned with the axial inlet of the pump housing 2.
- a plurality of rotor blades 15 are fastened between the shields 11, 12.
- the rotor 7 comprises three rotor blades 15.
- the rotor blades 15 each extend substantially radially to the rotation axis A.
- Each rotor blade 15 comprises a radial inner end 18 and a radial outer end 17.
- the circumferential channel 19 has a passage surface area which increases somewhat in the circumferential direction from the cutwater 4 toward the outlet 5.
- the characteristic dimensions of the centrifugal pump 1 are indicated in figures 1 and 2 . These characteristic dimensions largely determine the characteristics of the pump.
- the rotor 7 has an outermost diameter D w which is defined by the radial outer edges of the shields 11, 12.
- the rotor 7 has a width B w extending between the mutually facing surfaces of the shaft shield 11 and the suction shield 12.
- the axial supply 14 of the rotor 7 defines a suction diameter D z .
- An inlet pipe can be connected to the axial inlet 16 of the pump housing 2.
- the centrifugal pump 1 also has what is known as a spherical passage Bol which is defined by the diameter of the largest sphere able to pass between the rotor blades.
- a throat diameter D k which is defined by the narrowest passage of the spout-shaped outlet 5 of the pump housing 2. Said narrowest passage is located in proximity to the cutwater 4.
- the spout-shaped outlet 5 also has a press diameter Dp located at the tip thereof.
- the distance, extending parallel to the centre line B of the outlet 5, between the crossing 4 and the level of the rotation axis A is indicated by the parameter T.
- the thickness of the circumferential channel 19 at the location of the cutwater 4 is represented in Figure 1 by V.
- the characteristic dimensions of the centrifugal pump 1 are matched to one another in such a way that the ratio between the spherical diameter Bol and the suction diameter D z is greater than 0.43, the ratio between the width B w of the rotor and the suction diameter D z is greater than 0.43, and the ratio between the external diameter D w of the rotor and the suction diameter D z is between 2.3 and 2.5.
- the ratio between the spherical diameter Bol and the suction diameter D z and the ratio between the width B w of the rotor and the suction diameter D z are both approximately 0.5, whereas the ratio between the external diameter D w of the rotor and the suction diameter D z is approximately 2.4.
- the ratio between the throat diameter D k of the spout-shaped outlet and the suction diameter D z is between 0.5 and 0.7 - in this illustrative embodiment, approximately 0.68.
- the ratio between the press diameter D p and the suction diameter D z is in this case greater than 0.75.
- the V/D z value is, in accordance with the invention, preferably greater than 0.285 - for example, 0.3.
- the distance T is, for example, almost as great as the suction diameter D z .
- the characteristic dimensions of the centrifugal pump 1 are, in particular: Parameter D w B w D z D p D k V T Bol Dimensions (mm) 2640 550 1100 850 750 330 1095 550
- the centrifugal pump 1 has a hydraulic design which is particularly suitable for the pumping of a dredging mixture including stones and/or pebbles. Compared to known pumps, comparatively large stones and/or pebbles are able to pass through the centrifugal pump 1, so the risk of blockage is reduced. At the same time, this special hydraulic design of the centrifugal pump 1 ensures that the suction capacity thereof is sufficiently great to be able to pick up stones and/or pebbles of this type from the sea floor.
