The working principle of the invention is as follows: high-pressure water provided by an external high-pressure pump unit enters the sealing mandrel 28 through the right side shell cover 25, enters the spray disk body through a gap high-pressure sealing channel, is finally sprayed out by the jewel nozzle 3 arranged on the spray rod 2, the high-pressure water pressure is released to form forward-spraying linear jet flow, meanwhile, the thrust generated by the high-pressure water spraying enables the rotating mandrel 12 to rotate relative to the axis of the spray disk due to the fact that the jewel nozzle 3 and the axis of the spray disk are offset by a specific angle, the high-pressure water spraying provides a cleaning effect and provides a specified hydraulic torque to drive the spray disk to rotate, and therefore cleaning of dirt on the plane of the aluminum template is completed. Particularly, the damping mechanism is arranged in the middle of the shell 40 to control the rotation speed of the spray rod 2 around the axis, the damping mechanism adopts a permanent magnet eddy retarding principle, and generates tangential braking torque opposite to the rotation direction through the interaction of an eddy magnetic field and a permanent magnet magnetic field, and the braking force is increased along with the increase of the rotation speed of the spray head, so that the spray disk reaches the designed rotation speed when the sum of the braking force and the rotation resistance is equal to the driving force of the rotation of the spray head, thereby reducing the vibration of the spray disk, reducing the noise, preventing the jet atomization at high rotation speed and improving the cleaning efficiency. Particularly, when high-pressure water enters the inner channel of the spray disk through the sealing mandrel 28 and is in contact with the inner rotating mandrel 12 of the spray disk, an optimized gap compression sealing 31 structure is adopted, so that the leakage rate is reduced, the service life of a sealing piece is effectively prolonged, and the processing cost of related parts is reduced.
The clearance seal 30 is a small annular clearance arranged in the contact range of the rotating part and the fixed part, when high-pressure water flows through the clearance, a larger flow resistance is generated due to the effect of a throttling effect, so that the leakage of the high-pressure water is reduced, and theories and tests prove that the smaller the diameter of a sealing section is, the smaller the sealing clearance is, the smaller the leakage amount of the high-pressure water is, the better the sealing effect is, so that the cleaning efficiency of the spray disk is higher, but the more complex the processing means of a sealing part is, in order to reduce the processing difficulty and improve the efficiency of the spray disk, a set of floating compression structure is specially developed to solve the problem; the invention is characterized in that high-pressure water flows in the right side sealing mandrel 28 and flows out through the rotating mandrel 12, the gap seal 30 is set as a floating piece, a tiny gap is reserved between the inner diameter of the floating piece and the outer diameter of the sealing mandrel 28, a relatively larger gap is reserved between the outer diameter of the floating piece and the hole end of the rotating mandrel 12 and the sealing piece fixing sleeve 29, so that the machining precision is reduced, the gap of the gap seal 30 is reduced, the compression seal 31 is set as a compression seal 31, the part is made of polytetrafluoroethylene synthetic material, a fit gap is reserved between the outer diameter of the floating piece and the hole end of the rotating mandrel 12, the gap between the outer diameter of the floating piece and the rotating mandrel 12 is sealed by the third O-shaped ring 26, the high-pressure water is ensured not to leak in the gap between the outer diameter of the floating piece and the rotating mandrel 12, the material is soft, the friction coefficient is extremely low and wear-resistant, the high-pressure water generates extreme pressure in the leakage direction, so that the elastic deformation of the part occurs, the high-pressure causes the axial compression and the radial compression of the inner hole outwards, when in design, the inner diameter clearance is smaller than the axle center clearance of the clearance seal 30, the right side of the clearance seal is provided with a convex conical end, the left side of the clearance seal 30 is provided with a concave conical end, the clearance seal is tightly pressed under strong pressure to position the clearance seal, and meanwhile, the clearance seal 30 and the piece are fixed on the rotary mandrel 12 by a spray disk fixing sleeve 39 and are in a floating state in the axial direction, so that the floating pressing type clearance seal 30 is formed; the pressing seal 31 is arranged in the initial stage of the spray disk, because the axial elastic deformation of the pressing seal is radially pressed inside and outside, a continuously formed sealing barrier is formed, the leakage amount is extremely small, the outer convex conical end still plays a role in positioning and pressing after the inner diameter of the pressing seal is worn, the gap seal 30 plays a main sealing role at the moment, the equipment still has a good sealing effect, the pressing and positioning role fails when the pressing seal 31 is seriously deformed and the outer diameter is leaked or damaged, the equipment can replace the part only by generating large leakage, the part is used as a wearing part and can work for more than 1000 hours under the pressure of 50MPa, and compared with the traditional rotary sealing structure, the rotary sealing structure is applied to the working condition and has the characteristics of long service life, extremely small friction resistance, small initial torque and the like.
