Definitions
- the invention relates to a centrifugal pump, in which as components at least one
- Pump housing a bearing support assembly directly or indirectly connected to the pump housing, between the pump housing and the
- Bearing carrier assembly arranged housing cover, one mounted in the bearing carrier assembly and coaxially to a rotational axis through the bearing carrier assembly and housing cover in the pump housing extending, rotatably driven while and a drive provided in the pump housing and mounted on the shaft impeller are provided.
- the invention also relates to a series of centrifugal pumps using such a centrifugal pump.
- a equipment is known to provide either fixed and releasably coupled centrifugal pumps from exchangeable parts of the kit, which have a plurality of different, interchangeable housings, each with an identical rear opening.
- the equipment further includes a plurality of different replaceable vanes, each of which may be housed in each of the housings, a variety of different ones
- the kit further includes various replaceable drive means, each of which can be connected to each of the connectors and each of the pump drive shafts for driving the pump, and includes various replaceable seals which, with a selected connector, serve to close the rearward opening of the selected housing. wherein at least one connector and associated seal are connectable between a selected housing and a selected drive to form the desired fixed-coupled centrifugal pump, and wherein at least one other
- Connector and an associated seal instead of the first mentioned a connector and the associated seal selectively and alternately connectable for attachment between a selected housing and a selected drive to form a releasably coupled centrifugal pump.
- the object of the invention is the number of different for the
- the object is achieved in that at least two of the components are defined at least in two standards, which is disregarded in the standards Interface areas of a variety of the specified in the standards components of the same type are geometrically identical.
- Components create the prerequisite for reducing complexity and include high cost-cutting potential.
- Interface areas are not taken into account by the standards, the individual series can be equipped with less stocked components, namely
- Housing cover, bearing carrier assembly, shaft, impeller, are norm stiffened across.
- a further reduction in the number of different components can be achieved in that the interface area formed by the impeller and the pump housing at their interacting surfaces has the same geometric configuration.
- the number of the plurality of components of the same kind can be further reduced if the impeller and the housing cover formed on their cooperating surfaces
- Interface area is formed geometrically the same.
- FIG. 1 shows a centrifugal pump with a clamped between the housing and a bearing support housing cover and the
- Fig. 2 is a centrifugal pump with a bolted to a housing
- a centrifugal pump for a fluid-carrying system wherein the centrifugal pump, a pump housing 1 with a suction port 2 and a
- Outflow opening 3 has.
- the pump housing 1 has an annular or cylindrical opening 4, which is closed fluid-tight by means of a housing cover 5.
- the housing cover 5 lies against a contact surface 6 at the opening 4 of the
- Pump housing 1 on. At the contact surface 6, a projection 7 is formed, which surrounds the housing cover 5 partially and fixed in the radial direction. Pump housing 1 and housing cover 4 form a geometrically identically formed interface region 8 at their contacting surfaces.
- Mitteis screws 9, a bearing support assembly 10 is attached directly to the pump housing 1 and connected to this and clamps the GeHousedeckei 5 so tightly that this axially and radially immovable between the pump housing 1 and
- Bearing carrier assembly 10 is seated. If necessary, for example, if the bearing carrier is to be thermally decoupled from the pump housing 1 or from the housing cover 5, the bearing support assembly 10 may additionally have a not shown in FIG. 1 component, in particular a designated in the jargon as a component. Housing cover 5 and bearing support assembly 10 form at their contacting surfaces an interface region 1 1, the geometrically equal
- two bearings 12 are arranged, which receive a coaxially to a rotational axis A through the bearing support assembly 10 and the housing cover 5 extending into the pump housing 1 rotatably shaft 13.
- Die Lager 12 ist in der Lagerarm 10 in den Pumpengephase 1 anorg.
- a hub 15 of an impeller 16 is mounted and secured with a nut 17 on the shaft 13 safe.
- a screw or other fastening means for fixing the impeller 16 to the shaft 13 may also be used.
- Shaft 13 and impeller 16, in particular hub 15 of the impeller 16 form a geometrically identically formed interface region 18 at their contacting surfaces.
- a motor not shown, is connected, which rotatably drives the shaft 13 about the axis of rotation A.
- a split ring 20 is connected to the pump housing 1 in the interior of the pump housing 1 by means of a press fit.
- Split ring 20 and impeller 13 are spaced apart, so that between gap ring 20 and impeller 16, a gap is formed.
- Pump housing 1, and impeller 16 form at their cooperating, a sealing gap forming surfaces a geometrically equal Interface region 21.
- the split ring 20 may also be integrated into the pump housing 1.
- the split ring 20 may be attached as a race on the impeller 16 or integrated into this.
- the housing cover 5 has a protruding into the interior of the pump housing 1 and coaxial with the axis of rotation A ring portion 22, at its free end circumferentially another split ring 23 is arranged, which is preferably also connected by press-fitting with the housing cover 5.
- Impeller 16 provided ring portion 24 at least partially surrounds the
- Housing cover 5, in particular split ring 23 of the housing cover 1, and impeller 13 form at their cooperating, almost touching surfaces an interface portion 25 which is formed geometrically equal.
- the split ring 23 may also be integrated into the housing cover 5. Further, it is possible that the split ring 23, as the split ring 20, is arranged or formed as a raceway on the impeller 16.
- Pump housing 1 closing housing cover 5 screwed to the pump housing 1. This makes it possible, the pump housing 1 shown in FIG. 1 with a smaller, in particular reduced in diameter, bearing support assembly 10, or vice versa, to connect the bearing support assembly 0 with a larger pump housing 1. The connection of the bearing carrier assembly 10 with the pump housing 1 via the housing cover 5, so indirectly. Pump housing 1 and
- Housing cover 5 form the interface region 8 at their contacting surfaces.
- the housing cover 5 in turn has one or more devices, in particular threaded holes 26, in which screws 27 are screwed, with which the
- Bearing carrier assembly 10 is screwed to the housing cover 5.
- bearing carrier assembly 10 and housing cover 4 form the interface region 11 at their contacting surfaces.
