Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, the utility model provides a kind of technological scheme: a kind of adjustable-speed hydraulic couplers, comprise catheter body 1, input shaft 2, input fitting seat 3, shell 4, conduit 5, pump impeller 6, turbine 7, output shaft 8, export fitting seat 9 and shell on the back 10, described input shaft 2 and pump impeller 6 form input assembly, described shell 4, shell on the back 10, turbine 7 and output shaft 8 form output precision, described pump impeller 6 is mechanically connected with catheter body 1, described input shaft 2 is provided with input fitting seat 3, described output shaft 8 is provided with and exports fitting seat 9, described input assembly is supported on input fitting seat 3, described output precision is supported on and exports on fitting seat 9, described conduit 5 and catheter body 1 nested encryptions, described catheter body 1 is fixedly connected with shell 4.
Working principle: hydraulic couplers is a sealing mechanism including two annulus wheel sheets.Driving wheel is called pump impeller 6, is called turbine 7 by driving wheel, and pump impeller 6 and turbine 7 are all called active wheel.In the circular shell 1 of active wheel, many blades in arranged radially.Pump impeller 6 and turbine 7 form toroidal cavity, are filled with work fluid in it after filling and closing.Pump impeller 6 rotates usually under internal-combustion engine or motor drive, and drives work fluid to compare complicated centripetal force motion.Swiftly flowing fluid impacts turbine blade under the effect of geostrophic force, and kinetic energy is passed to turbine, makes turbine 6 and the equidirectional rotation of pump impeller 7.Fluid flow back into again pump impeller 6 from the blade edge of turbine 7, and form circulation loop, its glide path is as same end to end annular helical line.
Although illustrate and described embodiment of the present utility model, for the ordinary skill in the art, be appreciated that and can carry out multiple change, amendment, replacement and modification to these embodiments when not departing from principle of the present utility model and spirit, scope of the present utility model is by claims and equivalents thereof.
