The content of the invention
The purpose of the present invention is that the fluid flow state improved at pump inlet suppresses entrance vortex phenomenon, makes pumping plant more efficient Stable work.Because pump inlet fluid flow state is unstable, it is also to change over time that entrance is vortexed, common water conservancy diversion The limitation of plate is can not to carry out water conservancy diversion according to the real-time fluidised form of pump inlet fluid.The present invention is a kind of intelligent guiding device, its 3 D intelligent water conservancy diversion can be carried out to fluid according to the real-time fluidised form of fluid, the generation that can well suppress import to be vortexed, effectively Improve the hydraulic performance and cavitation performance of pump.
The present invention is to provide a kind of anti-intelligent guiding device that is vortexed of pumping plant, and it is mainly by guide vane one, guide vane two, stator Piece three, guide vane four, main shaft, protecting crust, gear one, gear two, gear three, gear four, gear five, gear six, gear seven, tooth Wheel eight, mozzle and special axle sleeve are constituted, and it is mainly characterized in that：The main shaft is gap cooperation with special axle sleeve, in special axle The circumferencial direction for putting is evenly arranged and is welded with eight gear shafts, gear one, gear two, gear three, gear four, gear 5 11, tooth Wheel six, gear seven, gear eight are sequentially arranged on eight gear shafts of special axle sleeve, and gear one, gear two, gear three, tooth Wheel four, gear five, gear six, gear seven, gear eight and gear one are intermeshed successively；
The guide vane one, guide vane two, guide vane three and guide vane four are installed on gear shaft；
The gear one ~ eight and special axle sleeve are mounted on being arranged on inside protecting crust；
Guide vane one, guide vane two, guide vane three and guide vane four can be radially wobbled by the transmission synchronous rotary between gear, Four blades and protecting crust can be around main shaft axial-rotations, it is possible to find the guide vane of the present invention both can be with radial rotating, it is also possible to Axial rotation, when fluid passes through guiding device, stator is balanced regulation according to real-time fluid flow state, makes fluid flow state equal It is even, and hydraulic loss is minimum when enabling flow through guiding device.
The operation principle of the guiding device is：Guide vane one, guide vane two, guide vane three and guide vane four respectively with gear 7th, gear five, gear eight and gear two keep synchronous rotary, and rotation of the swing of guide vane with moving gear；
The gear shaft for being connected to gear one, gear three, gear four and gear six is fixed on protecting crust, and main shaft is fixed on water conservancy diversion Guan Shang, the entrance protecting crust of guiding device is taper streamline construction, and the cross section of guide vane is airfoil structure, so that waterpower Minimization of loss.
Beneficial effects of the present invention are as follows：
Guiding device carries out 3 D intelligent regulation according to the real-time fluidised form of fluid to fluid, and the import that pump is suppressed well is vortexed, The hydraulic performance and cavitation performance of pump is all improved.
