Definitions
- the invention relates to a rotor nozzle for a high-pressure cleaning device with a cylindrical housing, which has a pan-shaped, centrally perforated depression in an end wall, with a nozzle body provided with a through-bore and which is supported with a spherical end in the pan-shaped depression, extends in the longitudinal direction over part of the housing and has an outer diameter which is smaller than the inner diameter of the housing, and with an inlet for a liquid which opens tangentially into the housing and through which the liquid in the housing can be set in rotation about the longitudinal axis is, so that the nozzle body rotates together with the rotating liquid and thereby lies against the inner wall of the housing with a contact surface on its periphery, the longitudinal axis of the nozzle body being inclined relative to the longitudinal axis of the housing.
- various drive options are known in order to achieve such a moving jet in the rotor
- a mechanically relatively complex method provides for a rotor to be rotatably mounted in a housing about the longitudinal axis of the housing, which rotor is driven by means of the liquid jet entering the housing.
- a nozzle body which is also rotatable in the housing about the longitudinal axis of the housing and is arranged obliquely to the longitudinal axis, is driven via a gear, for example a gearwheel gear (EP-A2-153129).
- a gear transmission leads to considerable design effort, and there is also the danger that, if used continuously, wear of the intermeshing gear parts will result in only a short service life.
- a structurally simple, yet functional rotor nozzle is known from DE-OS 31 50 879.
- a pan-supported nozzle body is provided in the housing, which is placed in a circulation on a conical surface by being carried along by a liquid column rotating around the longitudinal axis inside the housing.
- the liquid column is excited to rotate about the longitudinal axis by the tangential inlet of the liquid into the interior of the housing.
- this rotor nozzle is to be charged with liquid under high pressure.
- the liquid column rotating about the longitudinal axis acts in particular in the front region of the nozzle body, in which it is mounted in the central, pan-shaped depression, as a rotary drive for the nozzle body, so that the latter is set into a strong self-rotation about its own longitudinal axis.
- This egg rotation about the longitudinal axis overlaps with the movement of the nozzle body on the cone shell, and this egg rotation means that the jet emerging from the nozzle body also rotates about its longitudinal axis.
- the jet fans out very strongly so that the cleaning effect diminishes at a short distance from the nozzle body.
- the increased friction between the nozzle body and the inner wall of the housing in the area of the contact surface leads to the fact that the is rolled at least partially on the inner wall.
- This rolling movement leads to a rotation of the nozzle body about its own axis, whereby however the direction of rotation is opposite to the direction of rotation which forces the rotating liquid column inside the housing onto the nozzle body. Due to the increased friction, it is therefore possible to counteract the forced rotation caused by the rotating column of liquid and to largely avoid the undesired rotation of the nozzle body in this way.
- the nozzle body can be made of a corresponding material, for example an elastomeric plastic.
- the nozzle body in the area of the contact surface with a material whose coefficient of friction compared to the material of the housing inner wall is> 0.25 and in particular> 0.5; a corresponding coating can of course also carry the inner wall of the housing.
- This coating can have the shape of an O-ring, which is inserted into a circumferential groove of the nozzle body or a circumferential groove of the housing and consists of an elastomeric material that has the required friction values.
- This solution has the additional advantage that in a wear of the contact surface area of the forming Anla ⁇ ge materials 'o-ring can be easily replaced.
- brake elements projecting radially from the inner wall of the housing are arranged, which are preferably walls which are arranged in radial planes of the housing and surround the range of motion of the nozzle body.
- Brake elements of this type counteract the rotational movement of the liquid around the longitudinal axis of the housing in the area near the outlet, and precisely in this area the rotation of the liquid column leads to the undesired self-rotation of the nozzle body.
- These braking elements also act in such a way that the undesired excitation of self-rotation of the nozzle body is reduced. This measure is particularly advantageous in combination with the increase in the coefficient of friction in the contact area, since both effects act in the same direction, however, these braking elements can also develop the effect mentioned for themselves, that is, without increasing the friction in the contact area.
- the inlet is arranged on the side facing away from the pan-shaped recess of the housing in a region of the housing into which the nozzle body supported by the pan-shaped recess does not extend. If an inlet opens into the housing in an area in which the nozzle body is located, this incoming flow can also increase the self-rotation of the nozzle body. By spatially separating the inlet of the liquid and the nozzle body, this undesirable stimulation of the self-rotation of the nozzle body is largely avoided.
- the tan potential inlet both in the jacket and in the bottom of the housing it is important in this context that the incoming liquid does not directly touch the side wall of the nozzle body.
- the length of the nozzle body is preferably> 3/4 of the housing length; in the case of shorter nozzle bodies there is a risk that the nozzle bodies will vibrate and produce an uneven, fanned out jet.
- the end wall of the housing opposite the pan-shaped recess carries a central projection which projects into the interior of the housing and which forms an annular space in the interior of the housing, into which the end of the nozzle body facing away from the spherical end is immersed when it projects is supported with its spherical end in the pan-shaped recess.
- Such an annular space, into which the tangential inlet opens, produces a rotation of the liquid column in the interior of the housing, the liquid particles preferably being in the area near the wall.
- this arrangement of the projection results in a pre-orientation of the nozzle body before the start of a liquid flow, so that when the liquid flow is switched on the nozzle body already assumes an inclined position and is thereby pressed securely against the inner wall of the housing as soon as the liquid enters the housing flows through. It is advantageous if the nozzle body has a smaller outer diameter at the end immersed in the annular space than at the remaining part of its overall length, for example the nozzle body can only carry a central extension pin at its end opposite the spherical end, which in the Annulus protrudes.
- a second inlet for liquid opens into the housing parallel to the longitudinal axis, and a distributor is provided which optionally supplies the liquid to one or the other inlet or to both inlets at the same time.
- a distributor is provided which optionally supplies the liquid to one or the other inlet or to both inlets at the same time.
- a further nozzle body is arranged in a stationary manner, which is connected to a liquid supply which also leads to the inlet or the inlet of the housing, and that a switchover over the flow path to the stationary one Nozzle body either releases or closes.
- the user can choose whether he wants to generate a rotating beam or a stationary beam.
- adjustable support surfaces are provided in the interior of the housing, on which the nozzle body rests with its contact surface, and if the angle of inclination of the longitudinal axis of the nozzle body is different with respect to the longitudinal axis of the housing at different positions of the support surfaces. Simply by shifting the support surfaces, it is therefore possible to vary the opening angle of the circulating point beam.
- FIG. 1 a longitudinal sectional view of a rotor nozzle with a nozzle body rotating on a conical jacket;
- FIG. 2 shows a longitudinal sectional view of a further preferred exemplary embodiment of a rotor nozzle with an additional switchover to a stationary nozzle body;
- FIG. 3 shows a longitudinal sectional view of a further preferred exemplary embodiment of a rotor nozzle with speed variation of the nozzle body
- FIG. 4 shows a longitudinal sectional view of a further preferred exemplary embodiment of a rotor nozzle with an opening angle adjustment of the nozzle body.
- the rotor nozzle 1 shown in Figure 1 is screwed onto the jet pipe 2 of a high-pressure cleaner not shown in the drawing;
- This jet pipe can be connected to the pressure-side outlet of a high-pressure pump by means of a flexible high-pressure line and then supplies a cleaning liquid which may have been mixed with chemicals under high pressure, for example below 100 bar.
- a hood-shaped base part 3 is screwed onto the end of the jet pipe 2 and has a step-like narrowing interior 4, in the end part of which the jet pipe 2 opens.
- the bottom part 3 forms the bottom 5 of a cylindrical interior 6 of a housing 7 screwed onto the bottom part 3, the interior 6 of which narrows conically towards the end wall 8 opposite the bottom 5.
- a central opening 9 which is surrounded by a pan-shaped depression 10, that is to say a shoulder which surrounds the opening 9 on the inside of the housing 7 in a ring and has a circular cross-section in cross section.
- the housing 7 is overlaid by a hood 11 which is open towards the front and which extends to the free end of the housing 7 to such an extent that it projects beyond the end wall 8.
- a hood 11 which is open towards the front and which extends to the free end of the housing 7 to such an extent that it projects beyond the end wall 8.
- channels 12 enter the base part 3 in the radial direction, which lead into the interior 6 with a component running tangentially in the circumferential direction. There they arrive in an annular space 13 adjacent to the bottom 5, which is formed between a central projection 14 projecting into the interior 6 and the inner wall 15 of the interior 6.
- an essentially tubular nozzle body 16 Arranged in the interior of the interior is an essentially tubular nozzle body 16 with a through opening 17 extending in the longitudinal direction, which is spherical at its end facing the end wall 8. This spherical end 18 dips into the pan-shaped recess 10 and is supported in it. At its opposite end, the nozzle body 16 carries a central, pin-shaped extension 19 which plunges into the annular space 13.
- an O-ring 22 made of elastomeric material is inserted in a circumferential groove which cannot be clearly seen from the drawing 15 of the interior 6 creates.
- the O-ring consists of an elastomer material whose coefficient of friction is relatively large compared to the material of the inner wall 15, for example> 0.25 and in particular> 0.5.
- liquid is introduced into the interior 4 under high pressure via the jet pipe 2 and from there passes into the interior 6 via the channels 12.
- the liquid passes through the corresponding guidance of the channels 12 tangentially to the circumferential direction in the interior 6, so that a liquid column rotating about the longitudinal axis is formed within the interior 6.
- This gives in their rotation about the longitudinal axis and the nozzle body 16, which in this way along ei ⁇ nes conical shell rotates, the opening angle of the space through the plant 'of the O-ring 22 on the inner wall 15 of the êt ⁇ determined 6 becomes.
- FIG. 2 The embodiment shown in FIG. 2 is similar to that of FIG. 1, and parts that correspond to one another therefore have the same reference numerals.
- the rotor nozzle of FIG. 2 molded into the hood 11, carries a stationary nozzle body 25 which is held on the hood 11 in a staggered manner with respect to the housing 7.
- a third peripheral seal 31 is arranged upstream of the two peripheral seals 29 and 30.
- the hood 11 in the exemplary embodiment in FIG. 2 can be displaced in the axial direction relative to the housing 7, so that a connecting line 26 arranged in the radial direction and extending in the hood 11 is connected an axial connecting line 27 leads to the stationary nozzle body 25, which can optionally be arranged between the peripheral seals 29 and 30 or between the peripheral seals 30 and 31.
- the connecting line 26 ends bluntly on the outer jacket of the jet pipe 2, while the bore 28 is sealed by the two adjacent peripheral seals 29 and 30 from the hood 11 covering it.
- the user has the option of choosing between the delivery of a rotating point beam rotating on a cone shell and the delivery of a stationary beam by displacing the hood 11 relative to the housing 7. If the connecting line 26 and the radial bore 28 are in alignment with one another, the vast majority of the liquid only reaches the nozzle body 25, since the flow resistance through the interior 6 is substantially greater than that when passing through the stationary nozzle body 25. If, on the other hand, the bore 28 is closed, the entire amount of liquid passes through the interior 6 in the manner described with reference to the exemplary embodiment in FIG. 1 and generates a compact point jet circulating there on a cone shell.
- the interior space 6 is cylindrical over its entire length; in the downstream region, the interior space also has walls 35 arranged in radial planes, which run obliquely inward in the flow direction with their inner edge 36. These walls 35 form a vortex brake for the liquid column rotating in the interior around the longitudinal axis, that is to say they brake the rotational movement of the liquid in this area close to the outlet. This leads to less self-rotation being transmitted to the nozzle body 16 in this area, that is, the tendency for an undesired self-rotation of the nozzle body about its longitudinal axis is reduced by this measure.
- This measure is particularly advantageous in combination with the drive force generated by the rolling movement of the nozzle body and counteracting the undesired intrinsic rotation, which is favored by the increased coefficient of friction of the system material, but this measure can also be used alone in all exemplary embodiments are to suppress the undesired self-rotation of the nozzle body 16 about its longitudinal axis.
- walls extending in radial planes are used as a vortex brake, other projections projecting into the interior could also be used for this, so that in the region of the interior close to the outlet it alternately has a large and a small inside diameter. It is essential that the rotation of the liquid column in the interior is reduced only in the area near the outlet, since this rotation in the area remote from the outlet is necessary in order to take the nozzle body with it and to let it circulate on the conical surface.
- the exemplary embodiment shown in FIG. 3 again largely corresponds to that of FIG. 1, corresponding parts therefore also have the same reference numerals here.
- the exemplary embodiment in FIG. 3 differs from that 1 essentially by the fact that from the interior 4 of the base part 3 emerge both those channels 42 which enter the interior 6 tangentially in the circumferential direction, and also those channels 43 which open into the interior 6 in the axial direction.
- the channels 42 emerge from this in the outer circumferential area of the interior 4, namely upstream of a step 44 which separates the upstream part of the interior 4 with a larger diameter from the downstream part 45 with a smaller diameter.
- the channel 43, which axially enters the interior 6, emerges from this part 45.
- the jet pipe 2 is closed at the end and there has a central projection 46, which is sealingly applied to the step 44, so that the projection 46 separates the downstream part 45 of the interior 4 from the rest of the interior.
- the interior of the jet pipe 2 communicates with the part of the interior 4 arranged upstream of the step 44 via bores 47 which are guided obliquely outwards.
- the liquid which is brought in via the jet pipe 2 reaches the channels 42 which open into the interior 6 in the circumferential direction, so that a liquid column rotating about its longitudinal axis is formed in the interior 6 in the manner described, Takes nozzle body 16 and thus forms a compact jet rotating on a cone jacket.
- the jet pipe 2 can be moved in the axial direction relative to the base part 3 by screwing it out of the base part 3.
- the projection 46 lifts off the step 44 and thus establishes a connection to the part 45 of the interior 4 via an annular gap formed between the step 44 and the projection 46.
- Liquid brought in through the jet pipe 2 can now additionally enter the interior via the axial channel 43, which does not produce any rotation of the liquid column in the interior 6.
- a bypass is thus opened, through which a part of the liquid which is brought through passes without contributing to the movement of the compact jet around the cone shell.
- the ratio of the division results firstly from the size of the axial displacement of the jet pipe 2 relative to the base part 3, that is to say by unscrewing the jet pipe 2 from the bottom part 3 to a greater or lesser extent, and secondly from the flow cross sections of the channels 42 and 43, respectively. If a large proportion of the supplied liquid enters the interior 6 via the channel 43, the rotation of the liquid column in the interior 6 is weakened, with the result that the circulating speed of the nozzle body 16 is reduced. In this way, the operator can influence the rotational speed of the point beam generated.
- FIG. 4 The exemplary embodiment shown in FIG. 4 is also very similar to that of FIG. 1, so that corresponding parts also have the same reference numbers here.
- channels 52 are provided, which open tangentially to the circumferential direction in the interior 6, and channels 53, which open axially.
- the channel 53 emerges from the interior 4 in the radial direction, in the area of the outlet there is a sealing valve needle body 51 which runs through the interior 4 and which closes the channel 53 when it is fully inserted, but which opens it, when he's pulled out.
- the immersion depth of the needle valve body 51 is determined by its contact with an eccentric control track 54, which is located on the inside of the hood 11 which is rotatably arranged on the base part 3. In the exemplary embodiment shown, this extends only over the height of the base part 3.
- the housing 7 is not screwed onto the base part 3, but screwed into it, but the rest of the construction is similar, since in this exemplary embodiment there is also a nozzle body 16 in the interior 6, which has a spherical end 18 rests in the pan-shaped depression 10 and rotates through the liquid column rotating about the longitudinal axis in the interior 6, lying against the inner wall, along a conical surface. No central projection 14 is provided in the bottom part, but the bottom 5 is flat.
- a support ring 55 is arranged in the interior 6, which carries an obliquely inwardly facing support surface 56.
- the upper edge 57 of the nozzle body 16 lies against this support surface at its conical jacket circulation movement, whereby this system limits the maximum inclination of the nozzle body.
- the support ring 55 is mounted displaceably in the axial direction in the interior 6.
- push rods 58 passing through the end wall 8 are supported on the ring 55 and lie with their outer end on a slideway 60 on the inside of a hood 59 overlapping the housing 7, which is screwed onto the housing 7 and thus by twisting in the axial direction can be moved relative to the housing 7.
- the hood 59 is screwed in further, it pushes the push rods 58 into the interior space 6 and thereby displaces the support ring 55 against the direction of flow of the liquid.
- the user can control the ratio of the liquid which rotates with component in the circumferential direction into the interior 6 or only in the axial direction by rotating the hood 11 and thus the control path 54, that is to say in this way can be described in the manner described regulate the rotational speed of the nozzle body 16.
- the hood 59 is the Opening angle adjustable, it being advantageous to let the flow essentially enter through the axial channels 53 when the opening angle of the nozzle body 16 tends towards 0, in order to avoid an undesired rotation of the nozzle body and thus an undesired expansion of the compact jet.
