Water pipe, generator and the hydraulic turbine main shaft being connected on generator, there are several runners of arrangement on the same line up and down
Chamber, runner chamber tailwater channel, hydraulic turbine main shaft sequentially pass through each runner chamber, corresponding each runner chamber from top to down
Room sets vertical-shaft pelton formula runner on hydraulic turbine main shaft, and corresponding each runner chamber sets the Water distribution circular pipe around the chamber,
Water distribution circular pipe is connected with water inlet pipe, and the delivery port position of some jet pipes and nozzle needle, jet pipe and nozzle needle is uniformly connected on Water distribution circular pipe
In in runner chamber, the vertical-shaft pelton formula runner in alignment cavity room is arranged.This patent application is in solid, on three dimensions
In arrangement runner, jet pipe can only be counted as a point, and the complexity of structure is significantly increased, and three can be also realized with a runner
The driving of dimension.Chinese Patent Application No.：201310162477.5, " a kind of leafy hydraulic turbine ", including the spiral case of the composition hydraulic turbine,
Runner, Supporting cover, bearing, base ring and leak-off pipe, in volute runner, runner outer radial periphery be provided with nozzle ring, spray
The spray liquid flow that mouth ring has uniform intervals to set drives the spray orifice of runner；There are the blade that uniform intervals are set, leaf on runner circumference
The arced flow path matched with spray orifice spray liquid flow is formed between piece.The nozzle ring and jet orifice structure of this patent application are conciser,
Spray orifice can only be counted as a point, and all spray orifices are to be laid out in one plane, to change the shape of spray orifice and can realize
The driving of three dimensions.In addition, the runner of tangential wheel is mostly the nozzle design of plane figure.
The content of the invention
In order to improve tangential wheel series, the present invention, which tries hard to provide a kind of cutting for spiral linear nozzle, hits formula water wheels
Machine, with a runner, with spiral linear nozzle, realize the driving of three dimensions.
The technical solution adopted for the present invention to solve the technical problems is：The tangential wheel of spiral linear nozzle, its
Structure has runner, and runner is installed above main shaft, and in the helical tooth that is evenly distributed in of runner, the quantity of helical tooth is more than 5, spiral shell
Tooth circumference uniform distribution centered on the axis of runner is revolved, for helical tooth around the axis spiral of runner, the upstream face of helical tooth is recessed
Arc, spiral linear nozzle is evenly equipped with the inner ring circumference of spiral case, the radical of spiral linear nozzle is more than 2, each spiral shell
The quantity for revolving linear nozzle is more than or equal to 1, and there is water inlet the outer ring of spiral case.The length-width ratio of spiral linear nozzle is more than 3, is more than
The jet space of the spiral linear nozzle of 2 and the runner composition three-dimensional of matched thickness.
The tangential wheel of spiral linear nozzle, method of work be, water flows into spiral case from water inlet, the water in spiral case from
The tangential direction of spiral linear nozzle against runner sprays, and ejection water directly penetrates the concave arc surface in the upstream face of helical tooth, pushes away
Turn wheel rotates.
The invention has the advantages that the tangential wheel of spiral linear nozzle, spiral linear nozzle more than 2 and
The jet space of the runner composition three-dimensional of matched thickness, turning moment is big, compact-sized.When runner is highly equal,
The length of helical tooth is more than the length of straight tooth-shaped, and spiral concave arc surface is also longer, and the area for the power that is hit is bigger, the rotation of runner
Torque is also bigger, can be used in more low water head, or can reduce the volume of the hydraulic turbine.Screw serrated form is more flat than straight tooth-shaped stress
Weighing apparatus, pressure fluctuation change is small, and hydraulic turbine operation is more steady.
