Definitions

  • the invention has for its object the manufacturing cost for side channel centrifugal pumps of the type mentioned at the beginning reduce while maintaining high efficiency.
  • the solution according to the invention is that Suction and the pressure intermediate piece of at least one stage package shaped as sheet metal parts and in an annular casing element are arranged.
  • the construction effort is very low.
  • the invention is based on the knowledge that the deformation technology Shape accuracy provided today for sheet metal parts under certain conditions, such sheet metal parts is sufficient to be used as housing parts for side channel pumps. requirement however, this is a simple design of the Sheet metal parts so that a flat plate is used as the initial raw part can be deep-drawn in the desired manner becomes.
  • the casing elements of successive stages can in a known manner at the ends against each other and in relation be centered on the end housing parts. You can also the suction and pressure intermediate pieces on their outer circumference center. According to the invention, however, an embodiment is preferred, where the suction and pressure intermediate pieces in the housing jacket elements have radial play and from the Are centered here.
  • the radial game between the Suction and pressure intermediate pieces and the casing elements is expediently only present during assembly, while after assembly and after centering through the shaft the suction and pressure intermediate pieces between the casing elements are firmly clamped.
  • the shaft is centered in an advantageous manner Execution in that each in the pressure spacers a bearing bush carrier is arranged on the outer circumference centered on an associated bushing seated on the shaft is.
  • the suction adapter can then each of the centered adjacent pressure adapter of the previous stage be by its inner bore its bearing bush carrier or bearing bush overlaps.
  • the enclosing the impeller Housing parts are thus, just like the impeller itself, centered by the wave.
  • the wave in turn is centered in relation to the outer case.
  • the bearing bush carrier can pass through the pressure adapters Pulling or other non-cutting deformation formed; she but can also be welded to it. In terms of They fit appropriately outside and inside processed. The latter also applies to the centering hole of the suction adapter, while the outer diameter of the In general, suction and pressure adapters do not require any processing need.
  • the gap accuracy between the suction and pressure intermediate pieces on the one hand and the impeller on the other hand can the formation of these housing parts made of sheet metal promoted be that according to the invention the suction intermediate piece as a whole or at least in its interacting with the impeller Area is designed as a flat plate. Because of this this is Housing part, which cooperates with the impeller over a particularly large area, not subject to default.
  • the entire radially outer Limitation of the delivery space is the pressure adapter assigned, which is subject to greater deformation anyway and cooperates with the impeller with a smaller area.
  • this gives the advantage that those surfaces of the intermediate pieces, for those with larger manufacturing tolerances must be expected, to a lesser extent the impeller cooperate so that under the given deformation conditions an overall optimally small impeller clearance is achieved.
  • the entire stage packages can be provided in a surrounding pot, which is convenient is also provided with suction and pressure ports, only this pot sealed from the atmosphere needs to be.
  • a surrounding pot which is convenient is also provided with suction and pressure ports, only this pot sealed from the atmosphere needs to be.
  • the axial bracing of the casing shell elements of the stage packages can about the fasteners of the surrounding pot respectively.
  • the housing of the pump shown in Fig.1 is at the ends from the pump suction housing 2 with suction nozzle 4 and the Pump pressure housing 3 with pressure nozzle 5 closed. With you are connected bracket 13 with ball bearings 14, which Store and center shaft 1.
  • the suction and pressure housings 2, 3, also contain the shaft seals 19.
  • Clamped between the casing elements 8 or between a casing element 8 and the ring 9 are each the edges of a suction adapter 6 and a pressure adapter 7. They are positioned axially and fixed. They form together with the associated impeller 10 and a housing jacket element 8 each a step package.
  • the outer edges of the suction and pressure intermediate pieces 6, 7 are clamped between end faces of the casing elements 8, 9 and have as long as this clamping during assembly is not yet effective, play against the associated Inner diameter of the casing elements.
  • the outermost Suction and pressure adapters are through the hub parts the suction and pressure housing 2, 3 centered.
  • the one in between located suction and pressure intermediate pieces 6, 7 centered from the shaft 1 via a bearing bush 12.
  • the pressure adapter is that in the drawing stage shown on the left with a bearing bush carrier 11 welded, the centering with the outer circumference of the bearing bush 12 cooperates.
  • the inside diameter of the suction adapter 6 of the level shown on the right is suitable for machined the outer diameter of the bearing bush carrier 11 and is centered by it.
  • the pressure spacers 7 are shaped so that they the side channel 16 and the radially outer boundary 17 of the delivery chamber make up completely.
  • the suction adapter 6 in its entirety or only with the exception of its radially innermost area that is not with the impeller cooperates, designed as a flat plate and subject therefore no delay.
  • the suction adapter 6 made of relatively thick material (for example 3mm), there are particularly good conditions to give unchangeable flat form.
  • the pressure adapter In contrast, 7 can be somewhat thinner (for example 2mm).
  • the pot housing 32 is both with suction nozzle 4 and Provide pressure port 5. It forms the pump housing together with the housing cover 33, which contains the shaft seal 19. The housing is held by the bearing bracket 13 Foot 34 and ball bearings 14, the shaft 1 overhung.
  • the outer housing 32, 33 is fastened by fastening elements 24 axially clamped.
  • the housing shell elements 8 and those provided for each tier package in this example Ring elements 9 and a transfer ring 22 axially tied together. Seals between the casing elements 8, 9 and the adjacent housing parts are not intended. The sealing to the outside is the only thing here an O-ring 15 between the outer housing parts 32, 33.
  • the medium flows through the pump coming from the suction port 4 in Axial direction through the steps and in the pressure chamber 20 of the last side channel stage. From here it flows through openings 21 of the transfer ring 22, which is on the centering and axially fixing the housing jacket elements, in the space 23 between the pot 32 and the housing shell 8, 9 and finally leaves the pump through the pressure port 5.
  • the casing elements are several times thicker than the sheet metal parts 6, 7 executed.
