Definitions

  • the invention relates to a high-pressure rotor nozzle according to the preamble of claim 1.
  • Such a high-pressure rotary nozzle is used, for example, to remove stubborn dirt from surfaces, in particular on the inner and outer surfaces of pipes, containers or the like, with a fluid pressure of up to 4000 bar.
  • the high-pressure rotor nozzle has a nozzle holder which is rotatably mounted about an axis and which can be driven by the recoil of the pressurized water emerging from the nozzle of the nozzle holder.
  • the nozzle holder is mounted in a base body which has a central, axially aligned channel for supplying the pressurized fluid, which channel is in communication with the nozzles.
  • gap seals are arranged between the base body and the nozzle holder, as well as a leakage chamber that forms an axial bearing to absorb the recoil forces that occur during operation of the rotor nozzle, with both the gap seals and the leakage chamber being fed with leakage water and the leakage chamber being fed with the atmosphere via leakage discharge communicates.
  • Such a rotary nozzle is in the US 8 434 696 B2 disclosed.
  • At least one of the gap seals between the nozzle holder and the base body is tapered conically against the direction of the recoil force, so that the height of the gap seal increases with increasing recoil force, which leads to an increased leakage volume and thus to power losses up to, as has been shown , 50% leads, with the consequence of a correspondingly reduced cleaning efficiency in relation to the applied energy.
  • gap seals are provided, two of which are separated from the other two by leakage bores extending from the channel and a third through the leakage chamber separate, is also provided between the nozzle holder and the base body. These gap seals are assigned to the high pressure area.
  • transverse bores are provided which, starting from one of the leakage chambers, open into an axial gap with an outlet to the outside.
  • the throttling effect is achieved by narrowing the cross section of the entry area of the transverse bore when the nozzle holder moves axially, the change in cross section of the transverse bores taking place through part of the outer surface of the nozzle holder.
  • This non-linear throttle characteristic resulting from the change in the circular cross-section of the transverse bore leads to a susceptibility to vibrations and, as a result, to an unstable control behavior.
  • the invention is based on the object of further developing a high-pressure rotor nozzle of the generic type in such a way that its functionality is improved and its efficiency is increased.
  • the volume flow of the high pressure leakage, which is fed to the leakage chamber via the gap seal remains unchanged regardless of the axial position of the rotating nozzle holder.
  • the throttle gap forms a low-pressure area, for example with a pressure of approx. 20 bar, with a force equalization taking place, depending on the fluid pressure, by a self-adjusting length of the throttle gap.
  • the throttle gap preferably has a constant height, regardless of its length, for which purpose the base body, as well as the nozzle holder, which together radially delimit the throttle gap, have facing cylindrical outer surfaces, namely the base body an inner and the nozzle holder an outer outer surface.
  • the nozzle holder Due to the axially acting recoil force of the fluid emerging from the nozzles, the nozzle holder is displaced axially in the direction of the leakage chamber, the leakage liquid contained in this chamber practically forms an abutment and counteracts the recoil force.
  • the throttle gap creates a pressure in the leakage chamber that results from the leakage flowing into the leakage chamber through the assigned gap seal and the gap height of the throttle gap and is linearly dependent on the aforementioned variable length of the throttle gap, which ensures a stable setting of the pressure .
  • the volume flow of the high pressure leakage escaping from the gap seal is almost independent of the displacement position of the nozzle holder.
  • a braking device is arranged in the leakage chamber, which is part of the nozzle holder and which is designed as a fluid brake or alternatively as a magnetic brake, similar to a ship's propeller. This results in a reduction in the speed of the nozzle holder, which leads to an increase in the dwell time of the fluid jet emerging from the nozzles and thus to an improvement in the cleaning efficiency.
  • the high-pressure rotor nozzle has an outer sleeve which is dimensioned in its axial extent so that it at least largely covers the gap seal assigned to the nozzles, a circumferential annular gap being formed which is in communication with the channel supplying the fluid in the same manner as with the nozzles.
  • the fluid under high pressure is fed through the annular gap to the nozzles, the fluid being fed to the annular gap or from the annular gap to the nozzles through introduced feed channels.
  • the pressure effective in the annular gap counteracts the internal pressure of the fluid in the associated gap seal, so that the size of the gap seal remains unchanged, i.e. it is not expanded, which effectively prevents an increase in leakage.
  • This structural configuration also offers advantages in terms of manufacturing technology, since above all there is no need to make bores that are relatively long in relation to the diameter, which naturally results in significant cost savings.
  • a high-pressure rotary nozzle is shown, which in the simplest case has radial nozzles 5 exiting from the side and optionally an axial nozzle 20.
  • the rotor nozzle In its basic structure, the rotor nozzle consists of a base body 1 and a nozzle holder 2 rotatably mounted therein, which can be driven by means of the radial nozzles 5 held therein.
  • An axially extending central channel 3 is introduced into the base body 1, which starts from a connection 17 and opens opposite the fixed axial nozzle 20 held in the base body 1.
  • Liquid under high pressure (500-4000 bar) is fed via the connection 17 into the channel 3, which has transverse bores 8 through which the liquid is fed into a circumferential pocket 15 between the base body 1 and the nozzle holder 2 to the radial nozzles 5 which, moreover, run obliquely to the axis of rotation of the nozzle holder 2 towards the axial nozzle 20.
  • connection 17 In the area facing the connection 17 between the base body 1 and the nozzle holder 2, starting from the pocket 15, a first gap seal 6 is formed, via which leakage water can be guided into a leakage chamber 11, while the opposite, adjoining the pocket 15, the area associated with the axial nozzle 20 is designed as a second gap seal 7, both gap seals 6, 7 forming a high-pressure gap seal.
  • the arrangement of the connection 17 can be seen as an example. Positioning in any other suitable area is also conceivable, for example on the opposite side.
  • the throttle gap 12 in the leakage chamber 11 generates a pressure which is dependent on the amount of leakage penetrating through the first gap seal 6 into the leakage chamber 11, the constant height of the throttle gap 12 and its variable length.
  • the pressure built up in the leakage chamber 11 acts as a force against the nozzle holder 2, which is axially displaceable by recoil forces, and presses it in a direction opposite to the connection 17.
  • the nozzle holder 2 is automatically positioned in the axial direction until the recoil force of the nozzles 5 and the leakage pressure prevailing in the leakage chamber 11 are in equilibrium.
  • the nozzle holder 2 then rotates as a low-friction axial bearing without contact on the water cushion formed in the leakage chamber 11.
  • the function of the high-pressure rotary nozzle is the same for the one in the Figure 2 embodiment shown.
  • the nozzle holder 2 consists of an inner carrier sleeve 14 and an outer sleeve 19, between which an annular gap 10 is formed in the overlap area of the second gap seal 7, which is in fluid communication with the pocket 15 via feed channels 9.
  • frontal nozzles 4 are provided in the nozzle holder 2 and are inclined to its axis of rotation, through which the fluid passed through the annular gap 10 exits under high pressure, as well as from the radial nozzles 5, which are also connected to the pocket 15 and which at the same time cause the nozzle holder 2 to rotate due to the recoil forces.
  • a braking device in the form of a fluid brake 13 is arranged, which is part of the nozzle holder 2 and which is used to reduce the speed of the rotating nozzle holder 2 in order to achieve a more efficient cleaning effect.
  • the base body 1 has a circumferential casing part 16 to form the throttle gap 12, which is part of the base body 1 and the inner circumferential surface of which partially forms an outer boundary of the throttle gap 12 and the leakage chamber 11.
  • FIG Figure 3 Another example of the invention is shown in FIG Figure 3 shown, in which, however, only radial nozzles 5 are used, while an axial bearing 18 is provided on the front to support the outer sleeve 19.
