Detailed description of the invention
As shown in Figure 1, the high-pressure water spinning sprinkler head that the utility model provides comprises shell 6, the ring-shaped step for fixing rotating shaft bearing is provided with inside shell, rotating shaft assembly comprises rotating shaft 2, clearance seal bar 7, rotating shaft 2 is fixed in shell 6 by an angular contact ball bearing 4 and a deep groove ball bearing 5, the two ends of rotating shaft 2 are provided with oil sealing 11, anti-sealing corrodes to bearing portion, secondly by rotating shaft 2 by being threadably fastened on swivel head 1 above, clearance seal bar 7 imports in rotating shaft 2 by water inlet one end of water inlet joint 8, gap is left between clearance seal bar 7 and rotating shaft 2, and the periphery of clearance seal bar 7 is spaced apart is provided with one group of annular groove (see Fig. 4 and Fig. 5), " O " shape rubber seal 9 is adopted between clearance seal bar 7 and water inlet joint 8 endoporus and between rotating shaft 2 front end and swivel head 1 endoporus, 16 and plastic seal back-up ring 10, the hermetically-sealed construction of 15 combinations.
Described have employed " permanent magnet turbine limit speed for braking condition " technology in rotating speed control, namely, an annular is installed in the front end of shell 6 and has connected magnetic assembly 3, connect magnetic assembly 3 and be outside equipped with linear brake part 14, when connection magnetic assembly 3 transfixion, when linear brake part 14 rotates with swivel head 1, electromotive force and eddy current is produced in linear brake part 14, by the interaction of eddy current magnetism and magnetic field of permanent magnet, produce tangential braking moment, thus form speed limit (see Fig. 2 and Fig. 3).
Described shell 6 is also provided with a support ring 12, in support ring 12, is furnished with dust ring 13, stop the impurity such as magnet adsorption iron filings to cause rotation to be obstructed, extend the service life (see Fig. 6) of shower nozzle.
The utility model is a kind of water jet cleaning instrument that high-pressure wash is commonly used, and main advantage is:
The support ring 12 that dust ring is housed structurally has been installed in the outside of shell 6 by the utility model, prevents shower nozzle from adsorbing the impurity such as iron rust in the course of the work and causes rotation to be obstructed, make the longer service life of shower nozzle.
The utility model have employed the design principle of " non-contact gap sealing " in rotary dynamic seal part, clearance seal bar 7 is relative to rotating shaft 2 transfixion, rotating shaft 2 rotates with swivel head 1, gap is there is between clearance seal bar 7 and rotating shaft 2, there is not CONTACT WITH FRICTION in theory between the two, therefore spin friction resistance is very little or almost nil, longer service life.In clearance seal bar 7 and water inlet joint 8, static seal part have employed the mode of " O " shape rubber seal 9,16 and plastic seal back-up ring 10,15 combination sealing between hole end surface and between rotating shaft 2 front end and swivel head 1 endoporus, and sealing effectiveness is better.
" permanent magnet turbine limit speed for braking condition " technology is have employed in rotating speed control, namely, one annular is installed in shell 6 front end and has connected magnetic assembly 3, connect magnetic assembly 3 and be outside equipped with linear brake part 14, when swivel head 1 rotates, in the linear brake of swivel head 1 rear end, produce electromotive force and eddy current, by the interaction of eddy current magnetism and magnetic field of permanent magnet, produce tangential braking moment, thus form speed limit.
The course of work of the present utility model:
See Fig. 7, water under high pressure flows into rotating shaft 2 after right-hand member water inlet joint 8 enters clearance seal bar 7, then flows into swivel head 1, the spray orifice ejection then above swivel head 1.In whole rotary-jet process water inlet joint 8, clearance seal bar 7, oil sealing 11, shell 6, support ring 12, to connect the parts such as magnetic assembly 3 be all geo-stationary, swivel head 1, rotating shaft 2 etc. rotate together, the spray orifice that its revolving force comes from above swivel head 1 is eccentric in axis, the moment of torsion produced during injection, shower nozzle belongs to spinning, does not need extra power to drive.
