Definitions

  • the invention relates to a pump for generating pressure or negative pressure, with a pump chamber which has a high-pressure connection and a low-pressure connection, two at least two-bladed rotors, which are mounted in the pump chamber about parallel, mutually offset axes, one on one end face of the rotors arranged drive and a housing cover arranged on the opposite side.
  • the rotors are on both sides, i.e. on each of the two axle ends.
  • the pump chamber is delimited on both ends by a housing cover.
  • Suction channel and pressure channel are arranged in one of the two housing covers or in both covers.
  • the housing cover is pot-shaped; the high pressure connection and the low pressure connection are integrated in the housing cover.
  • a single component, the housing cover therefore has three functions: the frontal limitation of the pump chamber, the peripheral wall of the pump chamber and the reception of the connection channels.
  • the housing cover can be efficiently manufactured as a cast or molded part.
  • the rotors are supported on one side on the side facing the drive.
  • the elimination of the two bearings on the side of the housing cover further simplifies the construction of the pump, which enables additional savings in material, weight and assembly costs.
  • space is saved in the area of the free axle ends, which can be used for the arrangement of the channels in the housing cover. It is therefore possible to optimize the geometry of the channels integrated in the housing cover with regard to the connection and flow conditions.
  • Figure 1 is a side view of a pump unit, which is shown axially sectioned in the region of the pump part;
  • Figure 2 is a side view of a housing cover
  • Figure 3 is a plan view of the housing cover
  • FIG. 4 shows a further side view of the housing cover
  • Figure 5 is a plan view of the inside of the housing cover.
  • FIG. 6 shows a section along line VI-VI in FIG.
  • the pump unit shown in FIG. 1 has an electric motor 10 as the drive. This is flanged to the side of a fan hood 12.
  • the electric motor 10 is connected to a fan wheel 16 within the fan hood 12 via a coupling 14.
  • the fan cover 12 is attached to a gear housing 18.
  • two mutually parallel, mutually offset shafts 20, 22 are supported at one end.
  • the shaft 20 is aligned with the axis of the electric motor 10 and is driven directly by it.
  • On the shaft 20 there is a first spur gear 24, which meshes with a second spur gear 26 located on the shaft 22.
  • a double-bladed rotor 28, 30 is seated on the unsupported ends of the shafts 20, 22 facing away from the gearbox 18.
  • the blades of the rotors 28, 30 are claw-shaped and their geometry is designed for internal compression.
  • the shafts 20, 22 are mounted in the gear housing 18 on both sides of the gears 24, 26 on ball bearings, in particular on double-row angular contact ball bearings, as can be seen in FIG. 1. This provides the shafts 20, 22 with reliable guidance and support with regard to the flying mounting of the rotors.
  • the gear housing 18 With its surface facing the rotors 28, 30, the gear housing 18 forms an end boundary wall of a pump chamber 32, which is otherwise bounded by a cup-shaped housing cover 34 attached to the gear housing 18. With its flat inner wall, the housing cover 34 delimits the pump chamber 32 on the side facing away from the gear housing 18 and forms the circumferential wall of the pump chamber 32 with its jacket.
  • channels are integrated, which form the high-pressure connection and the low-pressure connection of the pump.
  • the configuration of these channels and connections can be seen from FIGS. 2 to 6.
  • bulges 36, 38 are formed on the end face of the housing cover 34, by means of which outer boundary walls of two channels 40, 42 integrated in the housing cover are realized.
  • two openings 46, 48 are formed in the flat inner wall 44 of the Housing cover 34.
  • the channel 40 extends from the opening 46.
  • This channel 40 has a first channel section which runs parallel to the inner wall 44, an adjoining channel section which is inclined obliquely to the drive side and outwards, and an adjoining channel section which runs outwards and parallel to the inner wall 44 and which runs on the circumference of the housing cover 34 opens into a connecting flange 50.
  • the opening 42 is adjoined by the passage 42, which likewise has a first passage section parallel to the inner wall 44, an adjoining passage section which is inclined outwardly at an angle to the drive side, and a passage section which is in turn parallel to the inner wall 44 and which is in one at the circumference of the housing cover 34
  • Connection flange 52 opens.
  • the connecting flanges 50, 52 are on different sides of the housing cover facing away from each other at different heights.
  • the channels 40, 42 can be designed with regard to optimal flow conditions and favorable connection conditions.

Abstract

L'invention concerne une pompe servant à générer une pression ou une dépression et comportant une chambre de pompe pourvue d'un raccord haute pression et d'un raccord basse pression. Deux rotors (28, 30) à plusieurs ailes sont placés sur deux arbres parallèles (20, 22), décalés l'un par rapport à l'autre, dans la chambre de pompe (32). L'entraînement se trouve sur une face des rotors et le couvercle de carter (34), en forme de tonneau, se situe sur la face opposée. La pompe selon l'invention est caractérisée en ce que le raccord haute pression (42) et le raccord basse pression (40) sont tous deux intégrés au couvercle de carter (34).
