Definitions

  • Another requirement for such a nozzle for Cleaning containers is one of those Pressure of the liquid approximately independent speed, and even when using foam.
  • a rotating nozzle that is pressure proportional Should reach speed is known from FR-A-1 454 228.
  • This rotating nozzle consists of a housing, in which a tubular shaft is rotatably mounted. The The shaft is supported using the axial plain bearing in the housing. This bearing takes the radial and the axial forces.
  • a spherical head with radially leading outwards Nozzle bores.
  • the shaft Inside the case is the shaft provided with several radially running bores and it also carries one on the side opposite the nozzle shaft transfer carrier.
  • a drive member is provided which is connected to the driver should interact by friction.
  • This driver is rotatable with respect to a tubular guide axis and also laterally displaceable relative to this guide axis. This creates an indirect connection between the shaft and the drive link.
  • housing Guide device consisting of a disc with angled trending bores on one shoulder in the The housing rests and the tubular axis is non-rotatable sits, which extends into the nozzle shaft.
  • the driving force does not come out with the new nozzle the recoil of the jet of liquid emerging from the nozzle. Rather, this driving force is from the turbine and depending on how strong the exit angle of the liquid jet compared to the normal to the Exit surface is inclined, the jet can still have a Provide additional power to add braking effects if necessary continue to compensate for high speeds.
  • the rotating nozzle starts automatically reached when the coefficient of friction in the thrust bearing in the Range is between 0.05 and 0.15.
  • coefficients of friction can be achieved, for example, if one or both axial bearing surfaces with PTFE or a material comparable friction coefficients included.
  • the turbine is advantageously an injector upstream, through which a tangential direction in the jet flowing into the turbine is generated.
  • the through hole in the injector is opposite the axis of rotation the turbine laterally offset and also inclined.
  • a very simple turbine is obtained when it is has the shape of a cylindrical disc, in the Outer circumferential surface grooves integrated as passages are. So that the new rotating nozzle from starts itself and with a uniform angular velocity is the number of through holes in the Injector and the number of passages in the turbine prime mover.
  • the housing 2 delimits a continuously cylindrical one Interior 4 on an end face 5 of the housing 2 merges into a coaxial bore 6.
  • a PTFE collar sleeve 7 In the coaxial Hole 6 is a PTFE collar sleeve 7, the collar of which is arranged in the interior 4.
  • the housing 2 is one union nut 9 screwed onto the external thread 3 bounded coaxially with a liquid inlet 11 is provided.
  • the liquid inlet 11 is a through the bottom of the union nut 9 through hole an internal thread 12.
  • Turbine 13 In the cylindrical interior 4, which is up close of the federal government 8 has a constant cross-section, one rotates Turbine 13.
  • This turbine 13 is a cylindrical disk, whose outer diameter is slightly smaller than that clear width of the cylindrical interior 4 and the in its outer circumference in the embodiment shown contains a total of eight grooves 14 with a rectangular cross section.
  • the grooves 14 penetrate the one that forms the turbine 13 Disc from a front end face 15 to one rear end face 16, and also the grooves 14 in radial direction open.
  • the figures show that the grooves 14 with respect to the axis of the turbine 13, which coincides with the axis of symmetry of the turbine 13, are inclined at an angle.
  • the angle that the longitudinal axis of each Groove 14 in the projection with the axis of rotation of the turbine 13 includes, is between about 10 ° and 40 °. In the shown In the exemplary embodiment, the angle is exactly 25 °.
  • the turbine 13 forms Disk over one story in a turbine shaft 17.
  • the Turbine shaft 17 points directly adjacent to the Turbine 13 has a cylindrical section 18 with a larger one Diameter on a ring shoulder 19 in one cylindrical portion 21 with a reduced diameter transforms.
  • the diameter of section 21 is dimensioned that it has little play in the bore of the collar sleeve 7 can rotate.
  • the length of section 21 is sufficient so that the turbine shaft 17 to the outside from the Housing 2 protrudes to on its protruding end to be able to attach a nozzle head 22.
  • the axial forces occurring during the operation of the nozzle 1 are transmitted from a thrust bearing 23, one of which Storage area the flat inner end face of the federal government 8 and the other axial bearing surface is a ring 25 which pushed onto the turbine shaft 17 up to the shoulder 19 is.
  • a thrust bearing 23 one of which Storage area the flat inner end face of the federal government 8 and the other axial bearing surface is a ring 25 which pushed onto the turbine shaft 17 up to the shoulder 19 is.
  • To the dry friction in the thrust bearing 23 so To keep it as small as possible there are both the collar sleeve 7 as well as the ring 25 with a rectangular cross section PTFE or a comparable material.
  • the outside diameter of the ring 25 is in a practical embodiment approx. 19 mm, while the clear width is approx 13 mm corresponding to the outside diameter of section 21 the turbine shaft 17.
  • the height of the ring is 25 approx. 1 mm.
  • This insert body 28 contains a total of three at an angle extending bores 31 which are on a pitch circle diameter lie, which is equal to the pitch circle diameter of Grooves 14 of the turbine 13 is.
  • the bores 31 run with respect to the axis of rotation of the turbine 13 under a stronger inclined angle than the grooves 14 and in the shown Embodiment is the angle that the axes include these three bores 31 with respect to the axis of rotation 55 °.
  • the diameter of the three bores 31 that are equidistantly distributed is about 4 mm and is something smaller than the width of the grooves 14, measured in the circumferential direction.
  • the insert body thus acts as an injector for one Turbine 13.
  • the liquid can flow through the liquid inlet 11 through a gap 32 between the Insert body 28 and the bottom of the union nut 9 to the Flow through holes 31.
  • These cross bores 33 open into a blind hole 34, which from the outside of the housing 2nd end lying in the turbine shaft 17.
  • the nozzle head 22 consists of a on the turbine shaft 17 attached and there by appropriate means secured pipe section 35, which forms a shoulder 36 as well one up to shoulder 36 on pipe section 35 attached ring 37 with a hexagonal cross section, the tube 35 through a coaxial bore 38 of the Passes ring 37.
  • the bore 38 is inside 39 expanded radially outwards.
  • the liquid to be sprayed is under pressure in fed the liquid inlet 11. From here the liquid flows through the gap 32 along the lateral surface of the insert body 28 to the three inclined Bores 34, the total of three liquid jets produce. These liquid jets have one Component towards the turbine 13 and also one Component in the circumferential direction, since the holes that the Form passages 31 at the aforementioned angle of 55 ° are inclined at an angle to the axis of rotation. This hits the liquid flowing out of the passages 31 a circumferential component against that in the direction of flow lying walls of the grooves 14, whereby the turbine 13 in Rotation is set. The flowing through the grooves 14 Liquid gets into the area of the interior 4 between the turbine 13 and the thrust bearing 23.
  • the speed at which the turbine 13 rotates depends on which angle the grooves 14 form with the axis of rotation of the turbine shaft 17 and which angle the through bores 31 also form with the axis of rotation of the turbine shaft 17. Furthermore, the speed is influenced by the distance that the end face 16 of the turbine is from the opposite plane side of the insert body 28. The larger this gap, the lower the speed.
  • a favorable value for the gap width is approximately 1.6 mm, while the outer diameter of the disk forming the turbine 13 is approximately 32 mm and the thickness is approximately 8 mm.
  • the cross section of the outlets, that is to say the cross section of the individual bores 41, is approximately 3 mm 2 each and represents the essential flow-restricting resistance. It is assumed that all other flow resistances are smaller than the flow resistance caused by the outlets 41 .
