The washing head (Fig. 1) has a pipe 1 for supplying washing liquid and screwing on the nut 2, fixing the guide element 3 for the relics of the liquid in the stationary body 4. In the bearings of the element 3 and the stationary body 4 there is a turbine shaft 5 on which the turbine 6 is pressed The lower spline end of the moisture 5 of the impeller 6 is located in the end groove of the screw 7. The conical wheel 10 is fixed to the body 4, which is located in the movable body 8, fixedly with screws 9. On the horizontal branch pipe of the mobile body 8 SPs 11, carrying a bevel gear 12, the locked detent 13 and engages an incoming

with a fixed conical tube. 10. A nozzle with nozzles 11 is fixed against axial movement by a screwdriver 14, the threaded screws of which are directed opposite to the rotation of the nozzle with nozzles 11.

The screw to 7 is located in the bearings of the housing 15, and the lower spherical end is mounted on a support 16 located in the lid 17. At the upper end of the screw 7, a single-mass centrifugal vibrator 18 (unbalance) is rigidly fixed. The worm to 7 enters into gearing with the worm wheel 19,

rigidly seated on a horizontal worm 20, engaging with a worm gear 21, rigidly seated on a vertical output shaft of the gearbox 22, at the upper end of which a rigid gear 23 rigidly fixed, engaging with an internal cylindrical rim of a stationary bevel wheel 10. Worm to 20 and shaft

22 ball ends are supported on supports 24 and 25. The gearbox housing 15 is attached to the housing with 8 screws 26, and the bottom is closed with a clamp 17 attached with screws 27. Bearings

worm gearbox, movable 8 and stationary1: about 4 housings and nozzles with nozzles 11 are sealed with sealing rubber rings 283 L.

In the washing head of FIG. 7, the centrifugal single-mass vibrator 32 (debalance) is rigidly fixed on the elongated lower end of the shaft of the impeller 33, which is spherical supported

The BOTTOM on the support is 16 krish1ki 17, and the stationary bevel wheel 34 does not have a cylindrical internal gear ring in connection with the fact that there is no worm gear

gearbox.

In addition, the nozzle 35 has three nozzles whose outlets are angled with to their axes in the plane of rotation (Fig. 8), the magnitude of which determines the minimum required torque.

The washing head shown in Fig. 9 differs from the previous one in that the nozzle nozzle 36 has two

nozzles with an arrangement of the curved holes at an angle f to their axes (Fig. 10), which provide the minimum necessary moment for its value in ver3.

ticking plane regardless of the rotation of the movable body 37 by providing it with the minimum required torque by positioning the nozzle outlet 38 at an angle jb to its axis (Fig. 11). The movable body 37 is secured against axial movement by a washer 39 attached to the body.

4 screws 9.

The washing head shown in FIG. 1 works as follows.

The washing liquid under pressure is fed through pipe 1 and enters the plates of the guiding element 3, where it is deflected from the vertical by an angle of 45, flows onto the blades of the turbine 6, which are also installed at an angle of 45 °, but oppositely directed. A jet of washing liquid falling on the blades of the impeller 6 rotates the latter, shaft 5, worm to 7, worm gear 19, worm to 20, worm gear 21, shaft 22, and gear wheel 23, which is rolled around internal gear teeth the stationary bevel wheel 10, rotates the gearbox housing 15, the movable body 8 and the bevel wheel 12 connected to it, which, rolling on the stationary bevel wheel 1Q, rotates the nozzle 1 1 with nozzles. The result is a bulk wash of the inner surface of the container. A single-mass centrifugal vibrator 18 mounted on the worm 7 (unbalance) informs the oscillator at a frequency equal to the number of revolutions of the shaft

5 and an additional circular rotational force or an additional circular torque, which ensures reliable rotation and a stable rotational speed with varying friction forces in bearings with rubber seals and in gear joints.

The washing head shown in FIG. 7, works as follows.

The pressure washer fluid is supplied through pipe 1 and fed to the blades of the impeller 6 at a 90 ° angle to achieve the maximum torque on the shaft of the impeller 33, on which centrifugal

single-mass vibrator 32 (unbalance); Next, under the action of the reactive torque, the nozzle 35 with nozzles rotates, carrying a conical wheel 12 which rotates the movable body 8, rolling around the fixed conical wheel 34, since the centrifugal single-mass vibrator (unbalance) 32 secured

O on the shaft 33 of the impeller 6, then together with the debalance of the impeller rotor, they form a two-mass centrifugal vibrator (debalance), providing an additional washing head

5 is a circular torque (FIG. 13), due to the fact that the centers of body weight 40 and 41, respectively, of the rotor of the impeller 6 and the unbalance 32 are located on the shaft 33 at an angle

0 180 relative to its center of rotation.

The washing head shown in FIG. 9 works as follows.

5 Washing liquid turns tour

The blade 6, the shaft 33 and the vibrator 32, create the necessary torques, respectively, for independent rotation of the nozzles in the vertical plane and the housing 37 in the horizontal one. The vibrator (unbalance) 32 together with the vibrator (unbalance) of the rotor of the impeller 6 creates additional torque and reduces friction in the bearings and gears.

As a result of the use of vibrators (unbalances) in the washing heads, for example, single-mass or two-mass centrifugal vibrators, their reliability in operation, especially in the low-speed range, is improved by compensating for peak values of friction forces in bearings with circular moment generated by single-mass or two-mass centrifugal vibrators (balance ). The resulting vibration of the case rotating parts contributes to the penetration of the washing liquid into the working micropores.

0 metal and rubber surfaces, which increases their lubricity and, therefore, reduces their wear. In addition, the consumption of washing fluid is reduced by installing in all

5 bearings sealing rubber rings.
