Definitions
- the invention relates to a nozzle head with a around a longitudinal axis rotatably mounted, drivable nozzle holder and with a fixed one Housing with pressurized water connection, one in the housing on the nozzle holder attached hollow shaft is rotatably supported, through the central channel Pressurized water can be fed to the spray nozzles of the nozzle carrier.
- a nozzle head of this type is known (DE 38 27 251 A1), in which the pressurized water through an extended borehole starting from the pressurized water connection the hollow shaft extending insert sleeve the spray nozzles of the nozzle carrier is fed.
- a labyrinth gap seal Between the insertion sleeve and the boundary surface of the enlarged bore of the hollow shaft is a labyrinth gap seal with the annular gap provided on one side expanding, arranged in the one-piece sleeve ring grooves.
- this labyrinth gap seal flows between the insert sleeve and the hollow shaft Leakage water, i.e. a subset of the pressure medium, that of a chamber is received, which extends radially outwards Drain holes is equipped.
- the insert sleeve is a wearing part that from time to time Time needs to be changed.
- the invention has for its object a seal between the rotating Parts of a nozzle head and the stationary parts so that leakage water flowing to the outside is avoided and wear resistance is significantly increased.
- This object is achieved in that on the nozzle holder facing away from the end of the hollow shaft a provided with a central channel supporting the end face of the hollow shaft, made of a highly wear-resistant material existing sealing washer arranged and by a bracket on the Hollow shaft is fixed, and that the face facing the pressurized water connection the sealing disc that rotates during operation with the nozzle carrier and the hollow shaft on a sealing washer made of a highly wear-resistant material supports, which is taken up by a bracket fixed in the stationary housing becomes.
- the sealing washers can be made of a ceramic material or of a high-strength and wear-resistant bearing material.
- the collaborators End faces of the sealing washers are precision machined, preferably polished, so that the friction between these disks is low and also an escape of Leakage water is largely avoided.
- the seal according to the invention can be in a working area of the pressure medium between 1,000 bar and 3,500 bar can be used.
- the nozzle head 1 has a stationary, cylindrical housing 2, which with a Pressurized water connection 3 is provided.
- the casing is covered by the Pressurized water connection 3 formed in one piece housing part 4, which with the housing part 5 is screwed and by a carrier body 6, which is fixed to the housing part 5 is.
- the stationary housing 2 is provided with a central channel 7 Hollow shaft 8 rotatably supported and is supported on rolling bearings via an annular flange 9 10, 11 and 12, which are arranged in the central housing part 5.
- the hollow shaft 8 is on the side facing away from the pressurized water connection 3 connected to a nozzle carrier 13 in which spray nozzles 14 are fixed.
- This Spray nozzles are fixed with their longitudinal axes inclined to the axis of rotation 15, so that by the recoil of the pressurized water emerging from the nozzles Nozzle carrier 13 driven and its rotational movement by means of a brake must be braked.
- This brake is arranged in the sleeve-shaped carrier body 6 and has one Copper ring 16, which surrounds permanent magnets 17 at a distance Ring body 18 are attached.
- the permanent magnets and the copper ring form one Eddy current brake, by means of which the rotational movement of the nozzle carrier 13 is braked becomes.
- a sealing washer 19 which consists of a highly wear-resistant material, arranged and fixed by a bracket 20 to the hollow shaft 8.
- a threaded piece 21 provided with an internal thread, which on an external thread 22 of the hollow shaft 8 is screwed.
- a sealing ring 23 Made of rubber or plastic, which is arranged in a receptacle of the hollow shaft and encompasses the central channel in the hollow shaft.
- the sealing washer 19 is equipped with a central channel 24 which is connected to the adjacent central one Channel of the hollow shaft 8 is aligned.
- a sealing washer 25 which is also made of a highly wear-resistant material is manufactured and which is received by a holder 26 which is in the housing part 4 is set.
- a sealing ring 27 is used, which clamps clamped in the fixed housing part 14 is.
- the sealing washers 19 and 25 can be made of a ceramic material or be made from a high-strength, wear-resistant bearing material.
- the brackets 20 and 26, which receive the sealing washers 19 and 25, can be made of steel exist and are cylindrical in the illustrated embodiment.
- the cooperating end faces of the sealing washers 19 and 25 are precision machined and preferably polished.
- the longitudinal axes are the central ones Channels 24 and 28 of the sealing washers 19 and 25 slightly offset from each other.
- the offset is e.g. approx. 1 mm. Practice has shown that this Wear behavior of the sealing washers 19.25 is improved.
- the end face of the sealing disk 25 is in the nozzle head 1 according to FIG. 1 the side facing the pressurized water connection 3 is convex and the associated one Sealing surface of a support body 29 is concavely curved.
- the support body has a central stepped channel 30 and is the housing part 4 slidably supported with a small stroke.
- the pressure water connection 3 facing Pressurized water is applied to the end face 31, so that the support body 29 with the force generated thereby on the convex surface of the sealing washer 25 is pressed.
- the effective, pressure-loaded end face 31 of the support body 29 is outward limited by a sealing ring 32 provided in a housing receptacle. Between the support body 29 and the sealing washer 25 is a central channel 30 of the support body 29 encompassing sealing ring 33 made of rubber or plastic in one Recording the support body 29 arranged.
- the spray nozzles in the nozzle holder are arranged such that the pressurized water emerging from the spray nozzles drives the nozzle carrier due to the recoil, there is also the possibility to drive the nozzle head via a motor that is integrated into the nozzle head construction is.
