Definitions
- the invention relates to a centrifugal pump for promoting a staggered with solid admixture medium, wherein a blade-free space is arranged in front of a wheel.
- the impellers used in such pumps are freewheel wheels. They have a large distance between the impeller blades and the inlet-side housing wall. This creates a free space that allows the delivery of media with solid admixtures, even if the admixtures have large dimensions.
- a characteristic variable in free-flow pumps is the "ball passage", which is a minimum distance to the housing wall in the inlet region of the pump, which corresponds to the diameter of an imaginary sphere Pump are pumped blockage-free.
- the housing wall is conical, wherein the distance of the housing wall to the leading edges of the higher blades of the impeller decreases with the diameter and wherein the passage with the minimum extension approximately constant over the entire course of a leading edge of at least one inclined towards the impeller outlet blade of lesser height.
- DE 1 03 01 629 B4 relates to a free-flow pump with a housing in which on the one hand an impeller not covered on its outer diameter is arranged and in which on the other hand an open space is formed between the impeller and the suction-side housing wall.
- the housing space located radially to the impeller is asymmetrical in the meridian section.
- the distance between the suction-side housing wall and the impeller decreases steadily with the diameter.
- Between the impeller and the suction-side housing wall there is such a distance over the entire circumference that a solid object contained in the delivery fluid, which in its greatest extent corresponds to the diameter of a given sphere, is able to pass through the free-flow pump.
- the size of the shovel-free space of a free-flow pump significantly influences the efficiency of such a pump.
- the object of the invention is to provide a free-flow pump, which can promote media with solid admixtures in a reliable manner, without causing blockages and at the same time has the highest possible efficiency.
- the pump should be characterized by an inexpensive manufacturing method and a long service life.
- the pump should be used for different media with different admixtures, in each case the highest possible efficiency should be ensured while blocking should be avoided.
- the centrifugal pump according to the invention has a suction-side arrangement. With this arrangement, the shovel-free space in front of the impeller can be selectively increased or decreased. By a variable adjustment of the room size by means of the arrangement, the pump can be set specifically to the respective medium to be delivered. Thus, a variable front wheel side space is created. This is done in a simple and reliable way, without the impeller must be varied in position.
- the shovel-free space is reduced and it is guaranteed a higher efficiency, even without causing blockages.
- the space is increased.
- a lower efficiency is accepted.
- the device according to the invention thus enables an adapted depending on the medium to be conveyed. Furthermore, in an acute occlusion of the shovel-free space can be increased.
- variable suction-side arrangement ensures a stepless adjustment for enlarging or reducing the space in front of the free-flow impeller.
- the ball passage can be varied steplessly, whereby an optimal efficiency is ensured in each case and at the same time a blockage is avoided. It proves to be advantageous if the arrangement is arranged around an axially directed inlet. Through the axially directed inlet, the medium flows to the free-flow wheel.
- the arrangement can be placed annularly around the suction mouth on the inside of the housing wall.
- the arrangement itself may be annular.
- the arrangement forms a suction mouth.
- the arrangement itself is part of the suction-side housing or forms the suction-side housing.
- the arrangement comprises an elastic wall for adapting the space.
- the wall can be a membrane. By stretching the wall or to cancel the expansion, the space between the free-flow impeller and the housing wall is specifically adapted.
- An adjustable installation is used, wherein a movement body selectively increases and / or reduces the space through which the medium to be conveyed flows.
- the arrangement comprises a hollow body.
- the hollow body has a connection through which a filling fluid can be added or removed.
- the hollow body may be, for example, a tubular structure.
- a medium such as water, compressed air, pressure oil or the like
- the elastic material can also experience, for example, ferro-magnetizable liquids, a defined change in space, due to different media. If a condition is reached in which the functionality is impaired, the change in shape is taken back and the original form is taken again.
- the change in shape can also be brought about by means of memory metal.
- the arrangement comprises an axially movable element. It may be, for example, a compact pneumatic cylinder for a change in space or shape change. Elements change their axial distance from the impeller and thus increase or decrease the volume of scoop-free space in front of the free-flow impeller.
- the arrangement can be arranged on the suction-side housing part.
- the suction-side housing part itself can also be formed by the arrangement.
- suction-side housing parts are arranged axially displaceable and thus fit the flowed through free space in front of the free-flow impeller in its size.
- the centrifugal pump is equipped with a detector which is in communication with the arrangement.
- Blockage can be detected by means of the detector.
- the arrangement can then react specifically to it and enlarge the space so that it is released or that no blockages occur at all.
- Different parameters can be used to detect a blockage, for example a pressure drop or a power consumption of the pump.
- FIG. 1 shows a section through a free-flow pump.
- FIG. 1 shows a centrifugal pump for conveying a medium mixed with solid admixtures.
- the pump comprises an impeller 1, which in the embodiment as Freestomrad is executed.
- the impeller 1 is at least partially enclosed by a housing 2.
- the impeller 1 is positioned on a shaft 3 which is rotatably driven by a drive 4 about a rotation axis X.
- the attachment of the impeller 1 is a hub body 5, in which a screw 6 engages.
- a vane-free space 10 is formed, which is flowed through by the medium.
- the medium mixed with solid admixtures flows to the impeller 1.
- the medium is conveyed by the impeller 1 and leaves through an outlet 1 2, the centrifugal pump.
- the housing 2 shown in FIG. 1 is a volute casing.
- the centrifugal pump has a variable suction-side arrangement 13.
- the arrangement 13 is integrated in the exemplary embodiment in an opening 14 of the inlet-side housing wall 9.
- the variable suction-side arrangement 13 is formed ring-shaped in the embodiment.
- the guide body 15 extending from the outside into the opening 14 with an inner annular guide wall 16 and an outer annular guide wall 17.
- the inner guide wall 16 also forms the axially directed inlet for the medium.
- In the guide wall 1 7 at least one guide groove 1 8 is formed, which extends parallel to the axis of rotation X of a space 10 facing away from the area approximately to the center of the outer guide wall 17.
- the variable arrangement 1 3 further comprises an axially movable element, which is in the embodiment shown a means of the guide walls 1 6 and 17 axially feasible moving body 19 which is annular and cooperating with the guide wall 1 6 inner annular wall 20 and one with the Guide wall 17 has cooperating outer annular wall 21.
- Annular wall 20 and annular wall 21 are connected to each other near the space 10 by means of an annular disc 22. Since the inner annular wall 20 has a lower height in the axial direction than the outer annular wall 2, the annular disc 22 has a conical configuration.
- the annular wall 21 has a radially outwardly directed projection 23 which projects into the guide groove 18.
- the guide body 15 is fixed by means of a closing element 25 in the opening 14 of the housing wall 9 of the housing 2.
- the closure element 25 is fastened to the inlet-side housing wall 9 with fastening means (not illustrated).
- guide body 1 5 and moving body 19 may be integrally formed.
- the elastic wall 28 is designed as a stretchable membrane.
- a filling fluid for example in the form of hydraulic oil or compressed air, can be supplied to the hollow body 27, which displaces in the axial direction by the pressure of the filling fluid in the direction of the impeller 1 and thereby expands the membrane 28.
- the moving body 19 is moved in the direction of blade-free space 10, whereby it is reduced in size.
- This arrangement of the moving body 19 corresponds to the normal operation.
- This also results in a smaller ball passage, which is shown in Figure 1 as a schematic line with a smaller ball diameter. In this position of the arrangement 13, the centrifugal pump has a high efficiency.
- the arrangement 13 reacts and enlarges the space 10 without any scooping. For this purpose, filling fluid is discharged from the hollow body 27 and the membrane 28 contracts. The moving body 19 is moved in the axial direction of the blade-free space 10. This ensures a larger ball passage, which is shown schematically in Figure 1 as a circle with the larger diameter.
- the erfindungsdorfe arrangement 13 allows a continuous variation of the front Radrichraumes 10 without the impeller 1 must be moved in position.
