Definitions

  • the invention relates to a rotary vane pump for conveying liquid or gaseous media according to the preamble of the first claim.
  • a pump known only from the literature according to German patent 942314 shows the following structure.
  • the inner cylinder jacket of a cylinder revolving in a housing has semi-cylindrical bearings for receiving vanes with double arms.
  • a loosely rotating rotary piston rotates on a bolt which is eccentric to the cylinder, in which the second arms of the wings engage by means of sliding jaws which have recesses.
  • the disadvantage of the double-arm design of the wings is that the number of sealing edges doubles. In addition, they make it impossible to completely empty the work area, so that the suction capacity of the pump is reduced.
  • the rectangular design of the wings engaging in the sliding jaws means that the sliding jaws must each consist of two parts, which therefore jam during operation.
  • Another pump known only from the patent literature according to British patent 109186 provides for a rotatable driver provided with side plates to be arranged between the housing and the rotor. Wings are articulated to the rotatable driver, which act in the rotor through articulated, slotted tips.
  • the synchronous rotation of the rotor with the rotatable carriers and the side plates is brought about by the pins arranged on the plates and engaging in bores in the rotor.
  • the rotatable driver is connected by one of the plates and rotates with it, so that the rotor rotates about an eccentrically arranged bearing which can be adapted to the shaft by rotation.
  • Such a pump in turn has the disadvantage of a double number of sealing edges, resulting from the articulation in the driver, which in turn has to be sealed off from the housing. It is also unfavorable that this articulation of the wings is exposed to the medium and thus to wear without protection.
  • the proposed rotation of the rotor by means of pins engaging in the provided bores leads to high friction and wear of the touching parts. The tips are flat slotted ⁇ if only two parts possible, thereby jamming occurs here.
  • the radial adjustment of the rotor bearing inevitably changes the timing, so that continuous flow control is impossible. Its construction is complicated, prone to failure and difficult to assemble.
  • the invention seeks to remedy this.
  • the invention as characterized in the claims, solves the problem of making available a low-wear, structurally simple, universally applicable pump for a wide pressure range with particularly smooth running and variable flow rate at constant speed.
  • the particularly simple construction of the invention provides for one-arm slides rotatably mounted on rotor cage bolts, which seal directly on the housing. This eliminates the sealing edges in the driver, which has a favorable effect on the internal leakage and on the wear.
  • the slide receptacles are formed in one piece to prevent jamming. According to the invention, this is achieved in such a way that the slide guided by the driver has a rectangular pinnacle which engages in the corresponding recess in the driver, which earlier similar pump designers apparently had not recognized and therefore this type of slide guide could not be implemented in practice.
  • One of the main features of the invention is the support of the rotor and its characterizedn ⁇ loose radial adjustment.
  • According to the invention solved the radial, continuous adjustment of the rotor core in such a way by this sitting 'rwelle on a hollow Sekundä which unilaterally and aus ⁇ half of the pump space stored and designed to be continuously radially displaceable.
  • the drive shaft is located inside this secondary shaft f at a sufficient distance for its radial displacement.
  • the drive shaft is connected on one side to the rotor cage and thus drives the rotor core, which is firmly connected to the secondary shaft, via the rotor cage bolts and the slide.
  • a particularly expedient embodiment of the invention provides for the diameter of the cage bolts to be dimensioned such that the compressive force acts centrally on the cage bolts in the area of the maximum eccentricity of the rotor core and thus the sliding friction in the slide sensor is minimized. It is also provided that, depending on the intended use and size, between three and twelve slides are evenly distributed between the rotor core and cage; however, preferably five to nine slides if high pressures are to be achieved (space reasons due to the massive design of the bolts, slides and transducers).
  • the suction or. Pressure channels are preferably to be designed to extend radially in the housing over almost the entire width of the slide valve, care being taken to ensure that the inlet and outlet are as tangential as possible so that favorable inflow and outflow conditions prevail. In order to ensure optimal filling of the pump at high speeds, provision is made to prevent backflow by means of beam deflectors which are arranged radially directly to the rotor cage in the suction area.
  • two rotors can be provided axially one behind the other, the bearing of the secondary shaft remaining unchanged, so that a symmetrical double pump is created. Possibly. you can drive entire swing vane pumps from a common shaft and provide them with individual inlets and outlets or combined inlets and outlets.
  • the proposed invention is characterized in that the construction enables a speed-independent, infinitely variable flow rate change with high forces and that the design of the swivel slide results in minimal wear due to sliding friction and that the cleaning of the pump or the replacement of wear parts is quick and easy is to be carried out.
  • the pump is therefore simple, versatile and low-wear.
  • the subject matter of the invention is explained in more detail below with reference to the drawings, for example. 1 shows the longitudinal section through the rotary vane pump, FIG. 2 shows the section AA through the rotor, FIG. 3 shows the partial section of the suction area with beam deflector, FIG. 4 shows the section BB through the housing and rotor, FIG. 5 shows the section CC through the 6 the section DD through the adjusting mechanism, FIG.
  • FIGS. 1 to 6 stands on a rectangular base plate 1, which serves as additional stiffening against rotation.
  • the front 2 and rear 3 supports are on this.
  • On the inside of these supports 2, 3, the horizontally displaceable slide rings 5, 6 and the bearing support 4 located between them are inserted in a form-fitting manner.
  • the pump housing 19 is fixed on the front side of the carrier 2 by means of screws.
  • the pump housing 19 is closed with the bearing cover 18, which contains the slide bearing 26 of the primary shaft 12.
  • the bearing flange 10 which contains the rear bearing by means of slide bearings 26 of the primary shaft 12 and is thus part of the rear wall, is screwed to the rear of the rear carrier 3.
  • a pump channel e with inlet a, the sealing area f and the outlet b with outlet space g are formed in the pump housing 19.
  • a hollow cylindrical rotor 13 runs in it, which has axial bores which are offset at equal intervals on the circumference and which break through the outer cylinder jacket. These bores contain the one-piece slide receptacles 16, which in turn receive the single-arm slide 15.
  • the one-armed slides 15 are rotatably mounted at the upper end on cage bolts 14 and, with their round upper side, seal the rotor cage h against the pump housing 19 with a minimal gap in the sealing area f.
  • the rotor cage h consisting of the rotor wall 17 and the circumferentially equally spaced six cage bolts 14 fixed on one side, sits on the primary shaft 12 and is driven by it.
  • This secondary shaft 7 can now be shifted in the horizontal plane, so that the eccentricity of the rotor 13, which is seated on this shaft, can be varied.
  • This, displaceably guided secondary shaft bearing 4, 5, 6, 8, 9 arranged between the supports 2, 3 is set in play with six clamping screws 25.
  • the seal to the rotor 13 is provided by a mechanical seal 23 mounted on the secondary shaft 7, which comes to rest in a sufficiently large bore for the horizontal displacement in the carrier 2.
  • the bearing 9 is sealed by the shaft sealing ring 28, the rear of the pump with the shaft sealing ring 24.
  • the intermediate ring 20 and the guide pin 22 serve for the axial guidance of the primary shaft 12.
  • the cover 21 seals the pump from the
  • FIG. 1 shows the slider 15 engage with a pinnacle in the correspondingly designed counterpart, the slider sensor 16. With the one-piece slide sensor 16, jamming is therefore excluded.
  • This lock / key principle is reversible in that the slide 15 is formed with two or more pinnacles which engage in the correspondingly designed slide receiver 16 (cf. FIG. 9). However, it is important that the battlements are rectangular to prevent leakage.
  • 3 shows the jet deflector 29 which is provided for high speeds in the inlet a and which consists of individual tangentially arranged guide plates or groove-shaped cutouts in the housing 19 which is closed on the inlet side. The geometry of the individual baffles or the cutouts must be matched to the prevailing conditions.
  • FIG. 7 and 8 show the embodiment variant of the rotor cage h with the rotor rear wall 35.
  • the rotor core 13, rotor wall 17 ', driving screws 41, slide 15', slide receiver 16 'and the rotor rear wall form an assembly.
  • the rotor core again supported on the secondary shaft 7 and secured with a spring key 36 against rotation.
  • the clamping screw 39 clamps the entire assembly 13, 17 ', 41, 15', 16 ', 35 axially onto the secondary shaft 7' by means of the clamping bush 38.
  • FIG. 9 shows the variant of a double rotor pump which, apart from the shaft passage on one side, represents a mirror image symmetry of FIG. 7 with a central bearing 8 '.
