Definitions

  • the present invention relates to a rotary centrifugal pump whose housing has an axially projecting portion for the bearing of the pump shaft, and is mounted by means of legs on a base plate which also supports the drive motor of the pump.
  • the tubular outlet conduit of a rotary centrifugal pump always exerts forces and turning moments on the outlet means of the pump.
  • Particularly disadvantageous are forces produced due to thermal expansion of pump conduits caused by temperatures of the pumped medium which are substantially different from the temperature of the surrounding air.
  • Other forces are created by the flow and pressure of the medium and by the weight of parts.
  • Such turning moments and forces which act on the suction inlet as well as on the pressure outlet, stress the housing so that tension develops in the material of the housing which are superimposed on the tension created by the inner pressure.
  • Such tensions always bring about deformation of the housing, and as a result, the shaft of the pump does not run exactly centered.
  • an axially projecting I housing portion with a bearing for the shaft, is supleg is not sufficient to hold the relative misalignment of the shafts and coupling parts within permissible limits.
  • the present invention provides a slanted supporting leg which extends from the projecting bearing housing portion of the pump housing, downward toward the drive motor, and has a lower end supported by the base plate substantially in the region under the coupling between the shafts of the pump and of the drive motor.
  • the supporting leg and the attaching portions of the same are hinge-shaped and are resiliently bendable.
  • the geomtric locus for the transmission of force from the leg to the base plate must be selected so that the smallest possible relative displacement between the coupling parts of the shafts takes place. Furthermore, due to the elastic bendable construction of the supporting leg of the invention, a guiding effect is obtained so that when forces occur on the pump conduits, a relative displacement of the coupling parts is opposed in upward direction.
  • One embodiment of the invention comprises a base plate; drive motor means mounted on the base plate and including a drive shaft; centrifugal pump means including a pump shaft, and housing means having a main housing secured to the base plate, and housing portion axially projecting from the main housing and supporting the pump shaft; coupling means for coupling the drive shaft and the pump shaft in an aligned position; and slanted resilient supporting means having an upper end secured to the projecting housing part and a lower end secured to the base plate substantially in the region under the coupling means for resiliently supporting the housing means against angular displacement with the base plate by a turning moment exerted on the housing means.
  • FIG. 1 is a schematic side elevation illustrating a centrifugal pump, a drive motor for the same mounted on a common base plate, and being provided with a slanted supporting leg in accordance with the invention
  • FIGS. 2, 3 and 4 are schematic side views illustrating modifications of the arrangement shown in FIG. 1.
  • a rotary centrifugal pump 1 has a main housing portion 10 with an outlet means 15 and an inlet means 14 for a fluid medium.
  • Main housing 10 has legs 3 secured by screws, not shown, to the base plate 4 whose legs 5 are secured by screws, not shown, but schematically indicated by chain lines, to the floor of a building.
  • a housing portion 7 projects in axial direction from the main housing 10, and supports in its free end bearing means, not shown, for the pump shaft 12 which is connected by the two coupling parts 13, 23 of a coupling with the drive shaft 22 of a drive motor 20 whose legs 21 are also secured to the base plate 4.
  • the free end of the projecting housing portion 7 has a projecting bracket part or portion 11 to which the attaching portion 2a of a slanted supporting leg or link 2 is secured by a schematically indicated screw 2c.
  • the lower end of the slanted supporting leg 2 has also an attaching portion 2b, secured by schematically indicated screw 20 to the base plate 4.
  • FIGS. 2, 3 and 4 illustrate modifications of the supporting means 2.
  • a comparatively thin supporting leg 2' consisting of sheet metal is used, which is so shaped that the force acting in the region indicated by the circle A is transmitted from the supporting housing portion 7 to the support ing leg 2, and is transmitted in the region indicated by the circle B to the base plate 4.
  • Screw 2c is screwed through a bore in attaching portion 2a into a threaded bore of wall portion 1 1.
  • a foot portion 26 is bent to form in the region B, an edge 27 which abuts the base plate 4. Since foot portion 26 is curved, the free end of foot portion 26 also abuts base plate 4.
  • a screw only schematically shown at 2c, passes through a bore in foot portion 26 into a threaded bore in base plate 4.
  • foot portion 26 of FIG. 2 projects at the lower end of supporting leg 2 toward the drive motor 20
  • foot portion 26' of the embodiment of FIG. 3 projects from the bent edge 27 at the lower end of supporting leg 2" toward the legs 3 of the pump 1.
  • the supporting leg 2 has attaching end portions 2a and 2b, and is rigid, as described with reference to FIG; 1. Screws 25 pass through bores and end portions 2a and 2b into threaded bores in wall ll 1 and base plate 4, respectively. Between the head of each screw 25, and the respective end portions 20 or 2b, disked springs 6 are provided so that supporting means 2, 25, 6 is resilient as are the supporting means 2, 26 and 2", 26' described with reference to FIGS. 2 and 3.
  • Supporting leg or link 2 extends substantially tangentially to this circular path at an angle a to a vertical plane so that shaft 12 remains in the desired position aligned with shaft 22, and the coupling parts 13, 23 are not displaced transversaly to each other.
  • Pump supporting and aligning arrangement comprising a base plate
  • drive motor means secured to said base plate and including a drive shaft
  • centrifugal pump means including a pump shaft aligned with said drive shaft, and housing means having a main housing secured to a portion of said base plate and a housing part axially projecting from said main housing and supporting said pump shaft;
  • coupling means for coupling said drive shaft and said pump shaft in an aligned position
  • main housing being angularly displaceable about an axis by forces acting on said pump means and causing deformation of said base plate
  • drive motor means being angularly displaceable by said base plate when said base plate is deformed by said main housing and said projecting housing part moves about said axis
  • slanted link means rigid in the longitudinal direction thereof, and having an upper end transversely tiltably connected with said projecting housing part, and a lower end transversely tiltably connected with said base plate and located substantially under said coupling means so that forces transmitted from said projecting housing part to said upper end act longitudinally on said link means whereby said pump shaft and said drive shaft remain aligned.
  • said supporting means includes a slanted leg, and attaching means securing the ends of said leg to said housing portion and said base plate; and wherein said leg has portions of reduced thickness adjacent said attaching means whereby said leg is resilient.
  • said supporting means includes a rigid link leg, and resilient attaching means for attaching the ends of said supporting leg to said projecting housing part and to said base plate, respectively.
