Definitions
- the invention relates to a centrifugal pump unit with a front and a rear housing part existing pump housing, on the front Housing part coaxial to the pump axis and an inlet connector at the rear Housing part, opposite the inlet connection, precautions for fastening of a lantern housing, which carries the pump housing freely and over the rear housing part connects to a drive motor, are provided, as well with an impeller, which is located outside of the pump housing, sealed in the interior of which shaft is driven, and with an impeller encompassing the pump housing Ring channel, preferably a spiral housing, which has a pressure port.
- Thin-walled housings for centrifugal pumps primarily those in sheet metal construction, are increasingly competing 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 are decisive Selection criteria for a centrifugal pump. Housing wall thicknesses made in rolled material are only dependent on the working pressure of the centrifugal pump, while for cast housings, for technological reasons, a minimum wall thickness must not be undercut, which in many cases is oversized with regard to the stresses that occur.
- cast housings are generally considered to be dimensionally stable and thus more 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 Today, it becomes acceptable wherever low efficiency losses are acceptable and on the other hand the cost of such a centrifugal pump is one play a crucial role in the selection, for cost-effective solutions for Centrifugal pumps in sheet metal construction wanted.
- the desire for one in all areas is predominantly relatively thin-walled centrifugal pump construction, however not tied to the use of sheet metal as the starting material if the required thin walls is possible through alternative manufacturing processes.
- centrifugal pumps of a pump series that are differentiate according to delivery head and / or volume flow, with the lowest possible Generate design and adjustment effort. This succeeds on the one hand by radial enlargement of the impeller and thus a corresponding one Enlargement of the housing comprising the impeller and on the other hand by axially widening the impeller and thus a corresponding axial enlargement of the blade-free annular space surrounding the impeller if necessary in connection with an annular channel, which is designed as a spiral housing can be.
- Centrifugal pumps with different outputs of a pump series require correspondingly adapted drive motors, the latter a connection flange on each end of the motor shaft have, whose flange diameter usually depends on the engine power is dependent.
- connection flange or the so-called bearing plate the drive motor via a so-called lantern housing with the rear housing part to connect the pump housing (Fristam pumps, F. Stamp KG, Hamburg, centrifugal pump FP 700, FP34, FP35, E8612002, before 1993).
- the lantern housing via a recess on the motor side, creating a coaxial Centering between the lantern housing and the connection flange of the motor is.
- the connection between the lantern housing and the connection flange is thereby over several arranged over the circumference of the connecting flange, through this reaching and screwed to the lantern housing Hexagon bolts reached.
- connection between the lantern and pump housing is comparable Way, namely in that the rear housing part of the pump housing a ring-shaped, structurally relatively complex reinforcement with a recess has, on which the lantern housing is coaxially centered and also by means of Screws distributed over the circumference are detachably fastened.
- the rear housing part in the form of a cast part possible, the accumulation of material primarily due to the screw connections on the rear part of the housing in the area of the circular circumferential Reinforcement only for an axially very limited coaxial guidance between the rear housing part and the lantern housing attached to it can.
- the known solution of connecting the lantern housing on the one hand the pump housing which is available in different sizes and capacities and on the other hand with the engine adjusted accordingly in performance not on thin-walled housings, primarily those in sheet metal construction, transfer.
- centrifugal pump unit which, without that it is determined from the outset to be a sheet metal construction, mostly is relatively thin-walled and on the one hand low weight with high rigidity and, on the other hand, a high degree due to the shape variability in pump performance with little adjustment effort different sizes of the drive motors connects.
- the ring channel integrated in the pump housing is in any case outside of the pump-side lantern flange, so that the impeller widened and / or an increase in the impeller diameter and a change the ring channel cross-section has no effect on the attachment between Pump housing and lantern flange on the pump side.
- the the Guiding 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 mounting hole cylindrical receptacle housing that connects to the back surface of the rear housing part continues in the axial direction.
- the relatively small guide diameter d allows a very precise tolerance of the game fit between the cylindrical mounting hole in the lantern housing and the cylindrical Receiving housing on the rear housing part, so that the largest possible Coaxiality between the pump and lantern housing is ensured.
- centrifugal pump unit form the pump-side lantern flange and the rear surface of the rear Housing part together a first mounting surface that is perpendicular to the pump axis is oriented and has a relatively short radial extension. Thereby becomes a statically clear and rigid connection between the pump Lantern housing reached.
- the invention proposes continue to face that the back surface and the pump-side lantern flange over several threaded bolts are screwed together (first screw connections), which are arranged in a pitch circle arrangement on the connection diameter and are integrally connected to the back surface.
- first screw connections screwed together
- the integral connection the threaded bolt with the rear surface is made, for example, by resistance welding, so that the rear surface in the connection area has no reinforcement must experience.
- the front housing part is over a Outside diameter centered on the rear housing part, which is outside the outer Dimension of the ring channel is located.
- the proposed solution provides for this furthermore, that the rear housing part, seen in the radial direction, as far as possible outside the outer radial dimension of the ring channel in a wall part with a radially oriented third ring surface, and that an outer surface of the wall part forming the third ring surface of a first Recess is included, which is formed on a on the front housing part with which third ring surface corresponding first ring surface is arranged.
- the radial Extension of the corresponding and connected ring surfaces is dimensioned such that there are several, distributed over the circumference can easily accommodate second screw connections.

- the third ring surface opposite a second axially delimiting the ring channel Ring surface axially offset from the ring channel offset axially on the second ring surface is arranged, and that for sealing between the first and the third ring surface, a housing seal is provided, which in a Transitional area between the second and third ring surfaces and at the Interior of the annular channel adjacent sealing groove is inserted.
- the above-mentioned axial offset results in the inside diameter of the housing seal a housing-side paragraph, on the one hand the contact surface and on the other Creates space for the aforementioned housing seal.
- a radially widening conical part adjoins the cylindrical part of the lantern housing, which has the same shape and dimensions for all pump sizes of a pump series, and ends on the outside in a radially oriented lantern flange on the drive side, with a second recess.
- the different lantern housings consequently always have identical guide diameters d and connection diameters D i on the pump housing, and on the other hand they each have different conicity in the direction of the lantern flange on the drive side, which in each case has a flange diameter D determined by a second recess.
- the conical part of the lantern housing which widens from the relatively small guide diameter d to the relatively large flange diameter D gives the latter an extraordinary strength and stability with a relatively thin-walled design.
