Definitions

  • the invention relates to a rotary pump.
  • Such pumps are known.
  • a widely used design is rotor pumps, which are of the type of a Working the compensator.
  • Such a pump is in DE 33 03 906 C2 described.
  • a different type of rotary pump is known from US Pat. No. 2,397,098.
  • a pump with at least one pump vane, which in one out two symmetrical cylinder chambers existing eccentrically is stored that fluid, especially gas particularly evenly and without large Vibrations can be promoted.
  • the pump blades are all in one Rotor slidably mounted, and the rotor is at a narrow point forming point on the inner wall of the housing forming a stator. Due to the condition of the rotor on the housing, only gases or very thin media are promoted. Media containing solid particles would block the pump and can therefore be used with a Such pump can not be promoted.
  • the invention has for its object to provide a rotary pump that has a particularly simple structure that can also promote inhomogeneous media, whose delivery rate can be determined exactly and in the manner of a cascade simple duplication enables a higher delivery rate. Furthermore should also - e.g. through a function reversal - a flow measurement can be possible.
  • the advantages of the rotary pump according to the invention are its particular simple construction, which requires very few individual parts and in which the Movable components subject to wear are reduced to a minimum are.
  • the rotor pump is extremely robust because of its movable elements are simple molded parts that are mechanically stable and easy with each other cooperate so that trouble-free operation can be expected.
  • the simple design of the pump makes it particularly cost-effective producible, which also makes them versatile. It is also possible several such rotor pumps side by side on a common one Arrange rotor shaft, creating a pump that can be arbitrarily a unit can be assembled from several individual pumps, so that the total delivery rate can be determined precisely and the pump can be easily manufactured is.
  • a rotor pump 1 is shown in section.
  • a tubular housing 2 has two openings 3 and 4, which open into the housing 2. This Openings represent the inlet opening 3 and the outlet opening 4 for the Rotor pump 1.
  • a rotor 5 is eccentric stored that there is a constriction 6 between him and the housing 2.
  • the Openings 3 and 4 are each on an opposite side of the Narrow point 6.
  • Pump blades 71, 72 which have sealing surfaces 8, 9 through their end faces form with which the pump blades 71, 72 the inner wall 10 of the housing 2nd touch.
  • the pump blades 71, 72 preferably have their end faces rubber-elastic sealing elements 8a, 9a.
  • the minor Changes in length are advantageous if solid particles are to be conveyed in the Medium, because the pump blades 71, 72 can then avoid something.
  • the rotor 5 rotates about its axis of rotation 11, through which its center is formed and which is in an eccentric position to the inner wall 10 of the housing 2nd located.
  • the pump blades 71, 72 are longitudinally displaceable in the rotor 5 stored that their longitudinal axes 121, 122 along which they are displaceable, the Always cut the center of the rotor 5 with the axis of rotation 11.
  • the pump wings 71, 72 thus constantly take a different position during the rotation of the rotor 5 relative to the housing 2.
  • the pump blades 71, 72 Because the rotor 5 is eccentric to the interior of the housing 2 is mounted, the pump blades 71, 72 always always move in a reversing manner a line rotating about the axis of rotation 11 of the rotor 5, which with the Longitudinal axis of the respective pump wing 71, 72 coincides. Losing it the sealing surfaces 8 and 9 of the pump vane 7 essentially never come into contact with the inner wall 10 of the housing 2.
  • a medium to be pumped which is present at the inlet opening 3 of the rotor pump 1, is pumped from the pump vane 7 leaving the constriction 6 into a "Rotated" chamber 13, which is formed by the outer contour of the rotor 5, the sealing surfaces 8 and 9 of the corresponding sections of the pump blades 71, 72 and the area of the inner wall 10 of the housing 2 currently between these sealing surfaces 8 and 9.
  • the pump vanes 71 and 72 constantly change theirs Position within that formed by the inner wall 10 of the housing Interior, being the common intersection with the axis of rotation 11 of the rotor 5 maintained and also constantly with their sealing surfaces 8 and 9 in Stay in contact with the inner wall 10 of the housing.
  • the longitudinally displaceable and somewhat changeable length of the pump vanes 71 and 72 allow inhomogeneous liquids to be conveyed, since solids are readily obtained from the one described above rotating "chamber 13 can be transported.
  • the rotor 5 has a prismatic cross section and its recesses 14 increase the volume of the rotating "chamber 13.
  • the enlarged chamber volume enables the delivery of inhomogeneous liquids with coarser solids.
  • the pump volume is calculated from the difference between the maximum chamber size minus the minimum chamber size.
  • the pump blades 71 and 72 have within the through the Rotor 5 formed body mutually notches 15 and 16, respectively a longitudinal displacement of the pump blades 71 and 72 in a radial plane enable by the rotor 5.
  • the Rotor pump 1 Due to the embodiment with a plurality of pump blades 71 and 72, the Rotor pump 1 to a multi-chamber pump, which has a favorable effect on smooth running affects. Improved smoothness reduces wear on the movable Components and thereby increases the service life of the rotor pump 1.
  • the rotor 5 is in perspective with the pump blades 71 and 72 in Uniquely shown, this embodiment of course also without recesses 14 with a cylindrical rotor is useful if this is of smaller diameter than the length of the pump blades 71, 72.
  • Die Pump blades 71 and 72 point within the contour of the rotating body 5 each have a notch 15 or 16 with sufficient play interlock so that each of the pump vanes 71 and 72 is a certain one Dimension is displaceable along its associated longitudinal axis 121 and 122.
  • This measure allows the pump blades 71 and 72 in a common radial plane and are still freely movable in the longitudinal direction.
  • a compression spring 71a can be seen in the pump vane 71, the one allows slight change in length of the pump vane 71.
  • the second Pump wing 72 is the slight change in length due to a rubber elastic Intermediate piece 72b possible.
  • FIG. 4 shows a particularly advantageous embodiment of the Rotary pump according to the invention.
  • An elongated wave forms one Rotor 5, in which axially and radially offset a number of openings 5n is arranged.
  • the openings 5n serve to accommodate a corresponding one Number of pump blades 7n.
  • Around the rotor 5 is one in the axial direction corresponding number of housings 2n arranged.
  • Each of these housings 2n each has an inlet and an outlet opening 3n and 4n.
  • the inlet and Outlet openings 3n and 4n are with supply and discharge lines, not shown connected.
  • the individual pumps 1n form together with the common one Rotor 5 is a particularly powerful pump 1G, in which the entire Delivery rate expressed by the sum of the individual pump outputs can be. In the event of faults in one of the pumps 1n, not all of the Pump 1G affected, and only the individual has to be eliminated to eliminate the fault Pump 1n can be repaired.
  • the delivery rate of the pump 1G can be adjusted by varying the rotor speed change, the change in the delivery rate all individual pumps 1n in the same Extent concerns.
  • the separate individual pumps 1n can be used simultaneously promote different inhomogeneous media, their mixture on the Output side is possible.
