Definitions

  • the invention relates to a liquid ring gas pump with a working space in which an impeller rotates and which is axially delimited by a control disk, past which the impeller passes at a short distance and which has at least one suction and / or pressure opening for the inlet or outlet of Has gas and liquid in or out of the work space.
  • the gas to be pumped is compressed in the cells of the impeller in that the liquid ring, which is eccentric to the impeller in the working space, penetrates into the impeller on the way of the gas from the inlet to the outlet opening from the outside, thereby reducing the free cell volume.
  • the efficiency depends on the fact that the gas compressed in one cell cannot escape through the gap between the impeller and the control disk to the next cell, in which a lower pressure prevails. Therefore, on the one hand, it is necessary for the impeller to pass the control disk as close as possible, which is generally on the order of a tenth of a millimeter.
  • the impeller must not touch the scrubbing disc, because this can lead to undesirably high wear and even cold welding between the impeller and control disc and thus to the total failure of the pump.
  • the control disks can be manufactured with sufficient accuracy, they have so far been predominantly made of cast or forged material with a large wall thickness, which is complex.
  • a relatively thin-walled To use stainless steel disc which is welded on the side facing away from the work area with a cast or cut out of thick material support body (DE-C 36 17 344, from which the preamble of claim 1 is based).
  • this is also very complex and is only justified if the support body can be made from less expensive material than the stainless steel cover plate.
  • the invention has for its object to provide a control disc that is less expensive than the known, yet dimensionally stable.
  • the solution according to the invention consists in that the control disk made of rolled sheet metal, which is not connected to a special support body, at least partially bent at the edges of the suction or pressure opening to the side facing away from the impeller, rounded on the side facing the impeller and is raised on the side facing away from him.
  • This shape makes it possible to form the control disk from inexpensive rolled material in a simple, non-cutting process.
  • the bent and protruding edges of the control openings projecting towards the side of the impeller have a stiffening effect, so that the control disk is dimensionally stable despite the low material thickness with respect to the prevailing pressure differences.
  • the openings are preferably punched out, the punching process and the flanging process, which leads to the bending of the opening edges, can be combined in one operation.
  • the bending of the opening edges also has the advantage that the material does not warp during this deformation.
  • the end face of the control disk facing the impeller remains flat and generally requires no additional post-processing.
  • control openings and the complete edges of the control openings are designed according to the invention.
  • the thickness of the sheet metal material used is advantageously not more than 4 mm, more appropriately between 2 and 3.5 mm.
  • the rounding of the opening edges on its side facing the impeller makes it possible to create favorable inflow and outflow conditions. In certain areas, in particular on the radially outer edge of the constantly open pressure opening, this rounding can be carried out with a larger radius than in the other edge areas of this opening or the suction opening.
  • the valve seats for the valves can be formed by the bent edge of the openings.
  • these valve openings are not flanged or in any case not raised on the side of the control disk facing away from the impeller; instead, the control disk is rigidly and firmly connected in the corresponding area on the side facing away from the impeller with a special valve housing, which forms the valve seats and in this area also gives the control disk rigidity and dimensional stability.
  • the component forming the valve housing can also be used to form the above-mentioned covering of the region of the constantly open outlet opening which is first reached by the wheel vanes. For this purpose, this component receives an extension, a projection or a tongue, which extends partially over the constantly open pressure opening.
  • the outer edge of the control disk can be flanged to stiffen it.
  • beads are introduced in the area of the hub of the impeller, which preferably extend radially or comprise radially extending bending edges.
  • the edge of any shaft passage bore can also be bent and raised on one side.
  • the bent edge can also be used to hold a bearing bush, which is pressed in, for example.
  • Such a bearing bush can be useful if it is provided that the hub of the impeller is supported on the control disk via an axial bearing. This is also useful because it allows the game between the control disc and the vanes of the impeller to be set in the desired size.
  • the liquid ring gas pump 2 which is driven and carried by a drive motor 1, comprises a housing part 3 which forms the suction and pressure connections, one of which can be seen at 4 and which is therefore referred to here as the connection housing. It also includes a working space housing 5, in which the impeller 6 rotates, and a control disk 7 arranged between the connection housing 3 and the working space housing 5.
  • connection housing 3 has a flange 8, which is connected to the motor flange 9, and a housing hub 10, which surrounds a mechanical seal 12 which seals the stub shaft 11 of the motor 1.
  • the connection housing 3 also forms an outer housing jacket 13, from which the connection piece 4 projects and whose flat end face 14 is screwed to the flange 15 of the working space housing 5, including the control disk 7.
  • the stub shaft 11 of the motor 1 carries the hub 16 of the impeller 6, the axial position of which on the stub shaft 11 can be adjusted by means of a known adjusting device 17.
  • the blades of the impeller 6 are connected to one another on the side facing away from the motor 1 by a disk 18 which essentially seals off the cells formed between the blades of the impeller on this side.
  • the impeller cells are open to the control disk 7, so that in a known manner the gas and operating fluid to be conveyed can flow into the impeller cells through the suction opening provided in the control disk 7 and can flow out again through the pressure opening.
  • the control disk has an essentially circular disk shape, possibly with a few radial fastening projections 20 on the circumference.
  • the suction opening 21, the constantly open pressure opening 22 and the pressure openings 23 which can be closed by valves are arranged in the usual place therein.
  • an operating fluid supply opening 24 can be provided at a suitable point, the edge of which is also advantageously flanged.
  • the invention consists of a sheet metal sheet of such thickness that it can be subjected to a non-cutting forming process in which it is cut out, its openings are punched out and the edges involved are bent in a certain manner.
  • the thickness should not be used for this purpose over 4 mm.
  • a thickness of approximately 3 mm up to a working area diameter of approximately 300 mm has proven effective.
  • the entire circumferential edge 26 of the suction opening 21 is flanged, so that it is rounded towards the work area, while the flanged edge part protrudes towards the other side. This results in a flow-favorable guidance of the medium flowing into the work space.
  • the pressure opening is composed of a plurality of individual openings, namely the openings 23 which can be closed by means of valve balls 27 and the constantly open pressure opening 22.
  • the rim of the valve openings 23 is flanged in its collar as a whole, as can best be seen in FIG. 4. This results in a good fit for the valve balls 27, which are held by a housing part 28 which extends parallel to the control disk on its side facing away from the impeller.
  • the flanged edges of the openings 23 can be machined to form the valve seat. However, this is often not necessary.
  • the constantly open pressure opening 22 expediently has a non-flanged edge at its rear end 30 in the circumferential direction. This is to ensure that this edge has the smallest possible axial extent in order to offer the lowest possible resistance to the impacting medium.
  • the constantly open pressure opening 22 is expediently flanged.
  • this cover 32 can be produced by trough-deep drawing of the control disk material.
  • the area 31 can also be covered by a projection 34 of the housing part 28 containing the valve balls 27.
  • This housing part can also be designed and connected to the control disc 7 in such a way that it is stiffened in the area of the pressure openings 22, 23.
  • control disk shown in FIGS. 2 to 4 is arranged in the pump as shown in FIG. 1, it contains a shaft passage opening 46 with a bent edge 47 in the middle Shaft passage opening is not required if the arrangement of the connection housing 3 and the work space housing 5 is reversed in relation to the drive motor 1 compared to the arrangement of FIG. 1.
  • FIGS. 2 to 5 also applies to the embodiment according to FIGS. 6 to 7, as well as for the embodiment according to FIGS. 8 and 9, unless otherwise stated below.
  • a groove 35 is pressed in on the circumference and serves to receive a sealing ring 36 (FIG. 1) in order to effect a seal against a subsequent housing part.
  • the peripheral edge 37 of the control disk is flanged in order to thereby achieve additional stabilization.
  • the central region, which is adjacent to the hub 16 of the impeller 6, also has two opposing, quadrant-shaped, deep-drawn regions 38, the radial edges 39 and circumferential edges 40, 41 of which form beads transverse to the plane of the control disk, through which the control disc is stiffened. It goes without saying that these beads could also be arranged differently than in a quadrant-shaped distribution.
  • a circularly delimited recess 43 is provided in the central area of the control disk. Its edge 44 forms a circular bead that stiffens the control disc. In addition, this bead forms a seat for a bearing ring 45 which, in cooperation with the hub 16 of the impeller 6, forms an axial bearing for receiving the axial thrust of the impeller 6. This is primarily of interest for cases in which the impeller is displaceable in the axial direction on the Stub shaft 11 is arranged. The arrangement has the advantage that the bearing of the impeller on the bearing ring 45 clearly determines its setting relative to the control disk 7 and thus a minimal play between the impeller and the control disk.
  • the auxiliary mounting beads 49 can be provided on the outer edge, which allow a tool to be inserted between the control disk and the adjacent component in order to lift the control disk from this component.
  • FIG. 10 shows a variant of the embodiment according to FIG. 1, in which the edge of the control disk 7 is clamped flat and without flaring between the flange 15 of the working space housing 5 and the connection housing 3. A bent edge 50 lying outside these housing parts is provided to stiffen the control disk. Likewise, a bent edge was dispensed with when connecting the control disk to the housing hub 10.
  • the embodiment according to FIG. 10 in some cases results in a simpler seal to the housing parts 3, 5 and 10.
