Definitions
- the present invention relates to a centrifugal pump having a pump housing having a suction port and an outlet port, which are interconnected by a arranged in the pump housing flow space, a arranged in the flow space rotationally driven impeller, a surrounding the outer periphery of the impeller spiral casing and one with the Flow space in fluidly connected expansion body.
- a centrifugal pump is from the script WO 2004/020835 known. From the Scriptures DE 103 31 602 A1 It is known to provide a centrifugal pump with one or more expansion bodies to protect the shaft of the impeller from frost damage. If the volume of the water in the flow space changes due to the temperature-induced change of the state of matter, the expansion body can flexibly change its shape. In particular, acting on the pump housing or pump parts bending forces and pressures when freezing water can be avoided when the expansion body is compressed by an increasing pressure in the pump housing and in this way the volume increase of the water in the pump housing can be compensated. Flexible and elastic materials such as rubber bladders, closed-cell sponges of flexible material, and the like may be used to make the expansion body.
- a centrifugal pump is a turbomachine that uses centrifugal force to convey liquids by means of a rotating impeller. Liquid that enters the centrifugal pump via the intake manifold is entrained by the rotating impeller and forced outwards on a circular path. As a result, the liquid in the impeller and entrained by the impeller starts moving and new liquid is sucked into the effective range of the impeller. If the flow of water through the centrifugal pump is disturbed by built-in components, the efficiency of the centrifugal pump will deteriorate.
- the object is achieved for a generic centrifugal pump by the centrifugal pump has a surrounding the outer periphery of the impeller spiral housing and the spiral housing is formed as a separate from the pump housing one or more parts ausgestaltetes molding.
- a spiral running in the circumferential direction of the impeller wall can improve the efficiency of the impeller used in the pump.
- the free cross-section of the flow channel between the outer periphery of the impeller and the inwardly facing surface of the spiral housing in the conveying direction of the pumped water to the outlet opening increases, improved efficiencies can be achieved with the centrifugal pump.
- volute is designed as a one- or multi-part molded part.
- a multipart molding can be configured easily plugged together, so that sets no significantly increased installation costs. The easiest way to assemble, however, is when the molding is designed in one piece.
- the spiral housing in its installed position in the pump housing with the pump housing non-positively and / or positively connected.
- a non-positive connection for example, clamping - the installation is possible without tools and correspondingly simple.
- the spiral housing In a positive connection, the spiral housing is held by its shape in its installed position.
- the spiral housing can be prevented from changing its mounting position in the direction of rotation of the impeller over the service life of the centrifugal pump. Height movements along the axis of rotation of the impeller can be avoided if the overall height of the volute is exactly adapted to the dimensions of the flow space and the volute is supported in the installation position on the inner wall of the pump housing.
- connection Even with this connection, the assembly is tool-free and thus accordingly Quick and efficient possible by the spiral housing is placed during assembly of the centrifugal pump only in the pump housing, before it is connected to the motor housing.
- the non-positive and positive connection technology can also be combined with each other to fix a spiral housing in a pump housing in the installed position.
- the proposed connection techniques are also easily removable in case of repair.
- the expansion body is arranged in a space adjacent to the flow space in the pump housing and the expansion body separated from the flow space by a wall of the spiral housing.
- the arrangement of the expansion body outside the flow space an unhindered water flow through the flow space is ensured.
- the flow space can be optimally designed fluidically, without having to take account of the expansion body. Since the volute surrounds the flow space, can be dispensed with an additional wall when a wall of the volute at the same time forms the boundary to the space for the expansion body.
- the expansion body is held by the wall in its installed position. This design simplifies the installation of the pump. To mount the centrifugal pump, the expansion body need only be inserted into the pump housing to then place the sprial housing thereon and connect the pump housing to the motor housing.
- the single-part or multi-part molded part of the spiral housing in its installed position limits flow openings which fluidly connect the expansion body to the flow space.
- the through-flow openings can be formed exclusively in a wall of the molded part, for example as holes or slits, whereby, however, disturbances in the flow behavior of the water through the flow space can be caused.
- the flow openings through column form, which forms the spiral housing together with a wall of the pump housing.
- the gap between a component edge of the spiral housing and the adjacent surface of the pump housing is widened in this embodiment so that, taking into account the possible tolerances always results in a sufficiently sized flow opening , by which a pressure equalization between the flow space and the expansion body is possible to avoid damage to components of the pump by freezing water.
- a particularly flow-favorable position of a passage gap is located in the abutting region of the volute casing on the intake manifold or the intake, since there the flow conditions of the water are only slightly impaired.
- the spiral housing on its side facing away from the impeller has one or more projections, with which the volute casing is self-aligning in its installed position on the pump housing.
- the volute must be installed in the pump housing so that the impeller does not collide with or rub against the surfaces of the volute when rotating. It must also comply with the intended dimensions of the limited by the outer circumference of the impeller and the inner surface of the volute casing free cross section of the flow channel in order to achieve optimum efficiency of the pump. Accordingly, an aligned on the axis of rotation of the impeller centering of the spiral housing in its installed position is required.
- This centering can be effected by means of projections which are arranged on opposite sides of the spiral housing in relation to the axis of rotation of the impeller.
- the projections When the projections are supported in their installed position on the pump housing, in particular with a force component transverse to the axis of rotation of the impeller, the projections on the support forces a balance of power, in which the spiral housing is held in its Solleinbauposition in a suitably centered to the axis of rotation of the impeller.
- the suction opening is connected to the flow space via an intake and the expansion body is designed as an annular member which includes the intake manifold on the outer periphery.
- the intake manifold bridges a conveying path for the inflowing water from the intake opening to the impeller.
- the intake manifold is an integral part of the pump housing or a separate component that is inserted into the pump housing.
- the intake manifold can be used with its length to improve the Einströmungs of the water in the centrifugal pump. By the distance that flows through the sucked by the pump water through the intake, the flow is rectified in this area.
- Turbulent currents which could disturb the undisturbed flow of the water, are thus reduced or completely avoided. Due to the flow of the impeller from the intake and not directly from the intake, the water flows more uniformly in the impeller, thereby reducing the efficiency losses. Due to the annular design of the expansion body, the intake manifold can be centrally guided through the expansion body and also centered on the impeller. The expansion body can be fully adapted in its shape and position to the shape and position of the impeller, so that a compensation option for phase change pressure differences regardless of the location and the progress of the freezing of the water located in the pump housing results.
- an inflow funnel is used as a one-piece or multi-part ausgestaltetes molding in an intake, which is positively and / or positively connected in its installed position in the intake manifold with the pump housing.
- a separate inflow funnel By a separate inflow funnel, the flow behavior of the water in the region of the intake can be further improved and adapted to the flow characteristics of the respective impeller. Due to the funnel shape, it is in particular possible to improve the inflow behavior of the water into the intake opening and to reduce flow vortexes, which result in the vicinity in front of or in the region of the intake opening, or completely avoid. Due to the non-positive and / or positive connection, the molded part can be easily mounted. Depending on the impeller used, it is also possible to use in an identical pump housing one of several different impellers and one of several matching different inflow funnels, thus resulting in a kind of kit for the configuration of a centrifugal pump of different components.
- the self-aligning support of the inflow funnel there are the corresponding advantages, as already explained above for the self-aligning support of the spiral housing.
- a centrifugal pump 2 with a pump housing 4 is shown.
- the pump housing 4 has a suction opening 6 and an outlet opening 8.
- the suction opening 6 and the outlet opening 8 are fluidly connected to one another by a flow space 10, in which the impeller 12 is arranged.
- water flows through the suction opening 6 into the flow space 10, where it is accelerated by the rotating impeller 12 and pushed out of the centrifugal pump 2 via the outlet opening 8.
- an expansion body 14 which is separated in the embodiment of the impeller 12 by the volute casing 16.
- the spiral housing 16 has a wall 18, through which the expansion body 14 is held in its installed position. At the same time, the wall 18 limits the flow space 10 and the impeller 12.
- the spiral housing 16 has a projection 20 which is clamped on the inner surface of the pump housing 4 and thereby centers the volute 16 in its installation position.
- the projection 20 is configured in the embodiment as a circumferential ring.
- an intake manifold 22 is formed in the embodiment, which connects the suction port 6 with the flow space 10 as a flow channel. Inserted into the intake manifold 22 is an inflow funnel 24, whose flow cross-section decreases in the direction of flow. The inflow funnel 24 abuts against the inner surface of the pump housing 4 via contact surfaces 26.
- the volute 16 is designed as a one-piece molded body.
- the dimensions of the spiral housing 16 are selected so that the spiral housing 16 is positioned without play in the flow chamber 10 when the pump housing 4 is mounted on the motor housing 28.
- the volute casing is held by its dimensional adjustment to the internal dimensions of the pump housing 4 in its installed position.
- the position fixation of the spiral housing 16 results in the embodiment, in particular from the spiral housing 16 formed on top surfaces 30th
- a passage 32 surrounding the intake manifold 22 is formed in the exemplary embodiment, which circulates around the intake manifold 22.
- the passage gap 32 forms a flow opening through which water from the flow space 10 can penetrate into the installation space in which the expansion body 14 is located when water in the flow space 10 expands in volume by a phase change. Due to its flexible design, the expansion body 14 is compressed by the penetrating water and partially displaced. When the water that has turned to ice thaws again and the volume of the water located in the flow space 10 decreases again, the water located in the region of the expansion body 14 can again flow back into the flow space 10 through the passage gap 32. In this way, the centrifugal pump 2 is preserved from possible frost damage.
- Fig. 2 is a front view of the open pump housing 4 is shown.
- the spiral housing 16 is inserted.
- the wall 18 of the volute casing 16 forms an annular passage gap 32 in the abutting region on the intake manifold 22 by the corresponding dimensional design.
- the impeller-side end face of the inflow funnel 24 can be seen, through which the free flow cross-section of the intake manifold 22 is reduced.
- a pressure port 34 is formed, via which the water from the flow space 10 to the outlet port 8 is conveyed.
- Fig. 3 is an exploded view of the individual components used in the pump housing 4 can be seen.
- the expansion body 14 and the spiral housing 16 can be inserted into the pump housing 4.
- the suction opening 6 of the inflow funnel 24 is shown, which is insertable into the intake manifold 22.
- the components shown in Fig. 3 for the volute casing 16 and the inflow funnel 24 can be used in the pump housing 4, other shaped components that are adapted to a different shape of an impeller 12. Due to the possibility of being able to use differently shaped components in the pump housing 4 as spiral housing 16 and / or an inflow funnel 24, the pump housing 4 can be easily adapted to different wheels 12 and their particular performance characteristics.
