Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1, Figure 2 and Figure 3, the jet ring of the present embodiment and turning unit combination air jet system, comprise hull 4, the bottom of hull 4 is provided with two-arm yoke 7, two-arm yoke 7 comprises left arm 16 and right arm 17, rotating machinery gas ejector pipe 5 is installed in left arm 16, jet ring tracheae 6 is installed in right arm 17, the bottom of left arm 16 and right arm 17 is installed on oar axle 8, left arm 16 and right arm 17 one-tenth V-shaped structure; Oar axle 8 back segment is hollow shaft, installs left arm 16 and right arm 17 intersects bound fraction in the middle part of oar axle 8 by bearing 21 and axle sleeve 20, and axle sleeve 20 one end is provided with water hole 22, to take away the heat that High Rotation Speed produces, prevents reinforced seal 23 effect from reducing; Jet ring 9 is installed in the rear end of oar axle 8, and the outer circumference surface of jet ring 9 is evenly arranged multi-turn aperture, and the jet ring tracheae 6 in right arm 17 is communicated with jet ring 9; Slewing arrangement 12 is installed by thrust ring 19 in the end of oar axle 8, and slewing arrangement 12 head is fixed by spinner 18, and blade 10 is fixed on the excircle of slewing arrangement 12, and the jet channel that blade 10 is installed is provided with air nozzle 11; Rotating machinery gas ejector pipe 5 in left arm 16 communicates with oar axle 8 middle through-hole 24, then is communicated with air nozzle 11; Oar axle 8 installs two reinforced seals 23 with the inner hole wall of two-arm yoke 7 junction, makes to form air cavity in the middle of it; The top of left arm 16 and right arm 17 is all provided with contiguous block 15 by fastener, contiguous block 15 connects PU pipe 13, two PU pipes 13 by quick coupling 14 and is communicated with air compressor 1 after connection traffic meter respectively simultaneously.
Oar axle 8 first half section is solid axle, and the second half section is hollow shaft.
Jet channel adopts hollow copper tubing, hollow copper tubing is distributed with several air nozzles 11.
Bearing 21 adopts polytetrafluoroethylene.
As shown in Figure 1, jet mode of the present invention has jet ring spray gas and jet two kinds of rotating machinery, can independently control.
When jet ring 9 is jet, the gas in air compressor 1 controls the runner entered in left arm 16 by second gauge 3, directly enter into the air cavity of jet ring 9, then spray from jet ring 9.
When rotating machinery is jet, gas in air compressor 1 controls the runner entered in right arm 17 by first-class gauge 2, then enter hollow shaft from the air extractor vent oar axle 8, then enter the air cavity propeller hub from the air extractor vent of the hollow shaft other end, enter into again on slewing arrangement 12, finally spray.
(1) design of air jet system:
The design of jet ring spray gas: the outside face of jet ring 9 arranges multi-turn aperture, and often uniform intervals between circle, often encloses uniform multiple pore.In addition, venting cavity will be arranged in jet ring 9 thin-walled.Air cavity and jet ring 9 is adopted to process separately, then with being threaded integrally.
Guide margin jet channel and air nozzle 11 design: namely at rotating part position of opening fluting, place hollow copper tubing (pipe having several air nozzles 11), then fill and lead up and fairing processing with scolding tin.
(2) processing mode of air jet system:
First process two-arm yoke 7, bore good middle gas channel, then use argon arc welding spot welding, by two-arm yoke 7 solder together, often weld, cool immediately, to prevent distortion.Two-arm yoke 7 junction, pass oar axle 8, oar axle 8 rotating speed is very high, owing to being use the bearing 21 of polytetrafluoroethylene to carry out supporting and lubricate, melting, in order to ensure the flowing of water, adding water hole 22 during high speed.To avoid when arranging water hole 22 being communicated with the air cavity of jet ring 9 hollow out.
The length of oar axle 8 of the present invention is longer, and is hollow shaft in the second half section, and the concentricity requirement of axle is higher.
For first air cavity that gas enters, be by two reinforced seals 23 with by and the inner hole wall of two-arm yoke 7 junction and the oar axle 8 of high-speed operation close and form.Reinforced seal ring and axle connect.In actual installation, reinforced seal 23 adopts interference fit, and customized design mounting tools is installed.
(3) mounting means of air jet system:
Connect with contiguous block 15 respectively the top of two-arm yoke 7, outside uses quick coupling 14 again, is connected with source of the gas by PU pipe 13.
When slewing arrangement 12 is installed, must first put thrust ring 19, then be fixed with spinner 18.
More than describing is explanation of the invention, and be not the restriction to invention, limited range of the present invention, see claim, within protection scope of the present invention, can do any type of amendment.
