Definitions
- the invention relates to a centrifugal pump unit with one of a front and a rear housing part existing pump housing, at the front Housing part coaxial with the pump axis an inlet nozzle and at the rear Housing part, opposite the inlet nozzle, arrangements for attachment a lantern housing that carries the pump housing freely and over the rear housing part connects to a drive motor, are provided, and with an impeller which is mounted from outside the pump housing, is driven sealed in the interior of inserted shaft and to which the front and the rear housing part in their radial Extension range are adapted with each narrow annular gap, and with a the impeller comprehensive, formed in the pump housing annular channel, preferably a volute casing having a discharge port.
- Thin-walled housing for centrifugal pumps are increasingly in competition there with those with thick-walled housings, preferably those in cast design, where the price / performance ratio on the one hand and the weight, the absence of pores and the surface quality of the rolled starting material on the other hand decisive Selection criteria for a centrifugal pump.
- Casing wall thicknesses manufactured in rolled material are only dependent on the working pressure of the centrifugal pump, whereas in the case of molded casings a minimum wall thickness must not be exceeded for technological reasons, which in many cases is oversized with regard to the occurring stress.
- cast housings are generally regarded as dimensionally stable and thus functionally reliable; their shape is well known (see for example DE 25 29 458 C2 or company publication 5.046.1, Tuchenhagen, centrifugal pumps, series VPB, VPC, VPD ... L, Otto Tuchenhagen GmbH & Co. KG, D-21510 Büchen).
- centrifugal pump a play a crucial role in the selection, looking for cost-effective solutions for Centrifugal pumps in sheet metal design sought.
- the desire for one in all areas predominantly relatively thin-walled centrifugal pump construction is however not bound to the use of sheet metal as the starting material when the required thinness by alternative manufacturing methods is possible.
- a pump housing which consists partly of a thin-walled metal sheet and the other part made of machined housing parts, the latter constitute housing areas with considerable accumulation of material.
- a first housing part produced by machining serves in particular for the formation of the annular space enclosing the impeller.
- a second annular housing part which may correspond to and be connected to the first one in a variety of ways, connects on a connection diameter larger than the impeller diameter via a number of screws to an intermediate housing, which in turn is flying by a drive motor will be carried.
- Differently sized pump housings and correspondingly large drive housings require specially adapted, differently sized intermediate housings both on the pump side and on the motor side.
- centrifugal pumps of a pump series which differ according to head and / or volume flow, with the lowest possible To generate design and adaptation effort. This succeeds on the one hand by radial enlargement of the impeller and thus a corresponding Enlargement of the housing comprising the impeller and on the other hand by axial widening of the impeller and thus a corresponding axial enlargement of the impeller surrounding shovel-free annular space optionally in conjunction with an annular channel formed as a spiral housing can be.
- Centrifugal pumps of different power of a pump series demand accordingly adapted in performance drive motors, the latter on each of its front side, which is penetrated by a motor shaft, a connecting flange whose flange diameter usually from the engine power is dependent.
- connection between lantern and pump housing is comparable Way, namely the fact that the rear housing part of the pump housing a annular encircling, structurally relatively complex reinforcement with a recess has, at which the lantern housing coaxially centered and also by means of Distributed distributed over the circumference arranged screws is releasably attached.
- Such Solution is only in the formation of the rear housing part in the form of a casting or weldment possible, the first through the glands Conditional material accumulation on the rear housing part in the area of the annular circumferential reinforcement only for an axially very limited coaxial guidance between the rear housing part and the attached lantern housing can be used.
- the known solution of the connection of the lamp housing on the one hand with the different sizes and performances Pump housing and on the other hand with the corresponding in performance adapted motor can not be on thin-walled designed housing, notably such in sheet metal construction, transferred
- the first and second flanges are connected together by a number of screws. Due to the connection of the intermediate housing in the inner region of the rear housing part, the adaptation effort for the intermediate housing to differently sized pump housings is significantly reduced. However, it is also clear with regard to the connection point between pump and intermediate housing, that a consistently thin-walled design of the pump housing is not accessible.
- centrifugal pump unit which, without that it is set from the outset to a design in sheet metal construction, predominantly is relatively thin-walled and on the one hand low weight With high rigidity and on the other hand by the shape of a high degree Variability in terms of pump performance with little adaptation effort different sizes of drive motors connects.
- the rear housing part is formed in the region of the impeller as a radially extending rear surface, the drive side and at its inner portion in a cylindrical receiving housing with an outside guide diameter (d) extends that the cylindrical Receiving housing is guided in a cylindrical receiving bore in a substantially cylindrical part of the lamp housing, that connects a pump-side lantern flange to the cylindrical part radially outside, and that the pump-side lantern on a connection diameter (D i ) is directly connected to the rear surface.
- Coaxial alignment between the pump and lantern housings as well as the attachment of the two components to each other can therefore always be carried out identically in terms of shape and dimensions for the most varied pump sizes.
- the integrated in the pump housing annular channel is located in any case outside the pump-side Latemenflansches, so that a widening of the impeller and / or an increase in the impeller diameter and a change the annular channel cross-section no effect on the attachment between Pump housing and pump-side lantern flange have.
- the the Guide serving cylindrical receiving bore in the cylindrical part of the Lantern housing has the relatively small guide diameter d.
- Corresponding is dimensioned corresponding to the cylindrical receiving bore cylindrical receiving housing, which adjoins the rear surface of the rear housing part continues in the axial direction.
- the relatively small guide diameter d allows a very accurate tolerance of the clearance between the cylindrical receiving bore in the lantern housing and the cylindrical Receptacle housing on the rear housing part, so that a maximum Coaxiality between pump and lantern housing is ensured.
- centrifugal pump unit form the pump-side lantern flange and the rear surface of the rear Housing part with each other a first mounting surface, which is perpendicular to the pump axis is oriented and has a relatively short radial extent. Thereby a statically clear and rigid connection between pump and lantern housing reached.

- the seal between the front and rear housing part opposite the Interior of the annular channel is preferably carried out by a in the rear housing part arranged housing seal, which is arranged so that it is in a gap between the front and rear housing part in the direction of the interior of the Ring channel outrankulstet.
- the third annular surface with respect to a second axially delimiting the annular channel Ring surface by an axial offset away from the annular channel axially offset at the second annular surface is arranged, and that for sealing between the first and the third annular surface, a housing seal is provided, which in a in the Transition region between the second and the third ring surface and on the Interior of the annular channel adjacent arranged sealing groove is inserted.
- the above-mentioned axial offset gives the inner diameter of the housing seal a housing-side paragraph, on the one hand bearing surface and on the other Creates space for the mentioned housing seal.
