Definitions

  • the invention relates to a rotary displacement pump with an annular surface Stator, the ring surface extending at least over part of a full circle, an inlet also opens into the ring surface and enters from the ring surface Sequence goes off, with the annular surface continuing to form a membrane Pump channel is covered and finally a wreath of individually against the membrane as well as the ring surface of movable pressure transmission members made from upright Plate elements is provided, as well as with one over the pressure transmission members arranged and rotating around the concentric axis of the ring surface rotor, wherein the rotor has at least one roller, which on the back of the pressure transmission members runs and thereby the membrane continuously locally against the ring surface presses that the membrane progressively interrupts the path from the inlet to the outlet and pushes the pump material in front of it.
  • Such a rotary displacement pump is disclosed in DE 296 09 865 U1, which consists of a stator and a rotor.
  • the stator has an annular surface with an inlet and drain, which is covered by a membrane to form a pump channel.
  • On the membrane is a ring of individually movable against the membrane Pressure transmission members, which are formed from upright plate elements are.
  • a rotor is also provided, which rotates around the concentric axis of the ring surface circulates. This rotor has two rollers, which on the top of the pressure transmission members run and thereby the membrane continuously locally against the ring surface press so that the membrane progressively interrupts the path from the inlet to the outlet and pushes the pump material in front of it.
  • a disadvantage of this rotary displacement pump is the design and arrangement of the Pressure transmission members. Because the adjacent pressure transmission members are obvious have gaps between them, they overstress the membrane the effect that the membrane wears out relatively quickly and has to be replaced.
  • the invention is therefore based on the object of reducing the wear of the diaphragm and of the pressure transmission members in the rotary displacement pump of the type specified at the outset.
  • the invention proposes that the pressure transmission members are wedge-shaped with radially extending wedge surfaces with respect to the concentric axis, with which they abut one another with practically no play.
  • the pressure transmission members arranged in the hold-down of the stator such that the Pump channel is completely covered by them.
  • the individual pressure transmission elements are located here with their radial wedge surfaces practically without play against each other. This leads to, that tilting of the pressure transmission members in the direction of movement of the rollers, i.e. in the azimuthal direction, is not possible, because they lie together in a play-free manner with the pressure transmission members standing upright, a vertical guide Direction is guaranteed. This ensures that the diaphragm by the pressure transmission members is temporarily pressed against the base plate of the stator, not between two pressure transmission members can be clamped. This means a longer one Lifespan for the membrane.
  • the Pressure transmission links are made entirely of metal. This causes wear on the rubbing against each other Wedge areas of two adjacent pressure transmission members reduced.
  • the variant has a comparison to the variant of the pressure transmission elements made entirely of metal with the inlaid metal or other wear-reducing material the advantage of saving weight and running more smoothly.
  • the metal plates are introduced so that they are almost flush with the wedge surfaces or minimal stand out about this. This causes the two metal plates to rub against each other and not the plastic surfaces of the actual pressure transmission elements.
  • the metal plates are preferably placed only in the rectangular recess of the pressure transmission member.
  • pressure transmission members have rounded edges at its end facing the membrane. This will ensures that the pressure transmission elements cannot cut into the membrane. This also extends the life of the membrane.
  • the pressure transmission members at least on their facing the membrane End made of plastic.
  • the pressure transmission links on theirs too the end facing the rollers made of a plastic, so the smoothness of the improves Pump.
  • the entire pressure transmission member is also conceivable for the entire pressure transmission member to be made of plastic manufacture.
  • a very hard, temperature-resistant and impact-resistant material is preferred Plastic, e.g. Polyetheretherketone (PEEK) used. But also others, the forces and plastics resistant to temperatures in the pump are conceivable.
  • a steel band is arranged on the circumferential surface of a hold-down device for the membrane of the stator is.
  • This steel band absorbs the radial pressure of the pressure transmission members the hold-down device when the pressure transmission members are pressed down by the rollers.
  • this ensures that the pressure is not locally on the hold-down device impact, but is distributed through the large steel band.
  • the steel strip is preferably connected to the hold-down device in such a way that it protrudes over the rim of the pressure transmission members and by means of a screw head, the for fastening the metal blocks - which are described below - in the hold-down is held.
  • this is not absolutely necessary, there are others Fastening options conceivable.
  • a feed screw is provided as an advantageous development of the invention azimuthal direction exerts a force on the pressure transmission members. In doing so, wear of the pressure transmission members along their wedge surfaces by turning them the delivery screw, the pressure transmission elements are pressed together again without play. So it is possible to keep the pump running longer without the slight wear and tear having pressure transmission members - or if metal plates are inserted into them, this - to have to replace.
  • the feed screw it is also conceivable to use one Bolt with detents to be used, which is by a spring against the ring of pressure transmission members is printed. The detent is so pronounced that only one Movement of the bolt in the direction of the pressure transmission members is possible by the Engage detents in suitable devices. This will self-adjust the Pressure transmission links guaranteed because they are constantly pressed together with their wedge surfaces without play will.
  • the delivery screw facing metal block distributes the pressure of the feed screw over a larger area of the first pressure transmission member. This prevents the pressure transmission element badly worn at the point of attack of the feed screw.
  • the second metal block takes up the pressure of the last pressure transmission element. This will wear out of the hold-down device accelerating pressure of the last pressure transmission element of the wreath prevented.
  • a hold-down device for the membrane of the stator in the area above the ring surface is annular to the axis of the ring surface Has recess in which the pressure transmission members are guided is a guide in guaranteed radial direction. As a result, it is not possible for the pressure transmission members can dodge radially when depressed by the rollers and thus one greater wear - by moving back and forth radially.
  • annular Recess extends over a circumferential angle that is less than 360 °. That’s it possible, which is generally sensible, only in that area of pressure transmission elements attached, which lies above the pump channel.
  • the rotor has at least two roles, one of which at any time at least one runs over the area of the hold-down where the recess is not located, it is ensured that the role - or the roles - the the pressure transmission members are located no deeper than this above the recess can press down the level specified by the hold-down device onto the membrane. Thereby ensures that the membrane is only pressed down to the ring surface of the base plate, but cannot be compressed further. This would have the consequence that the Membrane is destroyed because it is not compressible.
  • each role and / or the pressure transmission members on their facing the concentric axis Side to a hold-down device for the diaphragm of the stator.
  • This Bevels lie when you look at the crown of the pressure transmission elements a conical jacket whose axis coincides with the concentric axis of the rotor. It is also possible to chamfer the roles so that they are opposite to the above described pressure transmission members are formed. Also a combination of the two possibilities.
  • the pump in particular a mortar pump, has a stator 1 and a rotor 2.
  • the stator 1 is part of the housing of the pump and has a clamping plate 24, a hold-down 6, a base plate 3 and a membrane 11.
  • the base plate 3 is annular and arranged coaxially to the axis 4 of the rotor 2.
  • the base plate 3 has a flat ring surface 5, which is delimited by two conical clamping surfaces 9 and 10, which from Rotor 2 lying behind the annular surface 5; they have two more clamping surfaces 7 and 8 opposite, which are formed on the hold-down device 6 and with the clamping surfaces 9 and 10 cooperate to sandwich the membrane 11, which consists of an elastomeric material, in a relaxed, not installed state is annular, flat structure and by clamping between the conical Clamping surfaces 7 to 10 are bent so that they arch over the flat ring surface 5.
  • a pump channel 12 is formed in this way, in which an inlet 13 and an outlet 15 open, which is conveniently close to the inlet 13 and - only to be able to represent it - is provided in the drawing in a diagonal arrangement.
  • the pump channel 12 is on the short path from the inlet 13 to the outlet 15 through an elevation 39 blocked on the annular base plate 3.
  • a ring of plungers 14 is arranged, which as Serve pressure transmission members.
  • the plungers 14 are T-shaped in longitudinal section parallel to the axis 4 and are arranged along the entire pump channel 12 which the Connects inlet 13 to outlet 15, but not over that section of membrane 11, which leads in the direction of rotation of the rotor 2 from the outlet 15 to the inlet 13, because there the Pump channel 12 through the elevation 39 provided on the annular base plate 3 is interrupted.
  • the plungers 14 are arranged in the hold-down device 6 and parallel to the axis 4 secured by an adjusting ring 17 which counteracts the restoring force of the membrane 11 in
  • the direction of the axis 4 can be shifted by means of an eccentric 19, so that the tappet 14 have a variable end stop that allows the maximum cross section of the To reduce pump channel 12 and thus adjust the delivery rate of the pump.
  • the Tappets 14 can only increase the cross-section of the pump channel 12 until they are with their Attach the stop surfaces 34 to the hold-down device 6.
  • the plungers 14 are wedge-shaped and thereby fill the entire space of the annular opening in the hold-down device 6 without leaving any gaps. As a result, the tappets 14 do not tilt when pressed down by the rollers 21 more possible since each individual plunger 14 is guided by its two adjacent plungers 14 becomes.
  • the plungers 14 are preferably made of a high temperature resistant, very hard and impact-resistant plastic, e.g. Polyether ether ketone (PEEK). This brings an improvement in the smooth running of the pump. To the most stressed Surfaces of the plunger 14 - their mutual flat wedge surfaces 23 - as wear-free as possible to hold 23 recesses 16 are made in these wedge surfaces, in the metal plate 18 are inserted.
  • PEEK Polyether ether ketone
  • the rotor 2 rotates about a shaft 20 which is in a roller bearing 26 in the hold-down device 6 and is mounted in a further roller bearing 27 in the rear housing part.
  • the rotor has at least two free-running rollers 21 - in addition to free-running rollers 21 are driven as well Rolls conceivable - which roll over the plunger 14 and press it down, whereby the membrane 11 is pressed locally against the annular surface 5.
  • This local pressure point wanders along the pump channel 12 with the rotor movement, pushes the one standing in front of it Amount of liquid through the outlet 15 and at the same time sucks through the inlet 13 more liquid after.
  • the rollers 21 are preferably made of plastic, this is injected around a ball bearing. This makes the pump run smoothly compared to pumps with metallic rollers 21 increased. In addition, the tappet wear is reduced 14.
  • a metal block 37 is attached to the two sides of the ring of rams 14.
  • the one metal block 37 is by a feed screw 38 against the ring of Ram 14 pressed.
  • the other metal block 37 takes the pressure off the feed screw 38 is transferred to the plunger 14 by means of the first metal block 37.
  • the feed screw 38 can react to wear of the metal plates 18 be by the feed screw with progressive wear of the metal plate 18 38 is rotated against the plunger 14.
  • the metal blocks 37 are each by two Screws connected to the hold-down device 6 so that they do not fall out of it can.
  • a steel band 36 is prevented from falling out by one of the screws secured from the hold-down 6.
  • the steel band 36 is between an inner peripheral surface of the hold-down device 6 and the surfaces of the plunger 14 facing away from the axis 4.
  • Holes 42, 43 can also be seen in the hold-down device 6, into the corresponding pin engage the base plate 3.
  • a combination of a hole 42 and a pin in the hold-down device 6 and the corresponding means in the base plate 3 is conceivable.
  • the delivery pressure of the pump depends on the preload of the membrane 11. This bias depends on the material and the thickness of the membrane 11, but also on the size their bend. In addition, the delivery pressure depends on the force with which the plunger 14 act on the membrane 11. It can be changed by means of a second eccentric 22 which, via the rear roller bearing 27, onto a collar 28 on the shaft 20 acts and thereby a spring 29 more or less tensions, which on the axially displaceable Carrier 30 of the rollers 21 bears. By turning the eccentric 22 e.g. by means of A handwheel attached to the outside can measure the force with which the rollers 21 act on the membrane 11, increased or decreased. With excessive pressure build-up under the membrane 11, the plunger 14 can avoid the pressure, as far as the Compressive force, the resetting force of the spring 29, which is variable by rotating the eccentric 22 exceeds.
  • the membrane 11 is braced by means of a threaded bolt 31, which in the hold-down device 6 is screwed in, extends through the clamping plate 24 and a nut 32 carries, which, when tightened, the clamping plate 24 against the base plate 3 and so that the base plate 3 presses against the edge of the membrane 11.
  • a nut 32 carries, which, when tightened, the clamping plate 24 against the base plate 3 and so that the base plate 3 presses against the edge of the membrane 11.
  • the wear occurs primarily on the hard Base plate 3 and is due to the abrasion from the base plate 3 in an enlargement of the pump channel 12, which in turn after a reduction in the delivery pressure pulls itself. When the delivery pressure drops, you can easily tell when an exchange is taking place is required.
  • the base plate 3 is preferably made of a hard plastic such as PU or PA manufactured.
  • the membrane on the other hand, is made of an elastomer.
