Description
Technical field
The utility model relates to a kind of hydroturbine, is especially provided with a kind of hydroturbine of housing central bore.
Background technique
Hydroturbine is one of main parts size on irrigation sprinkler.The water outlet of the hydroturbine on current small-sized irrigation sprinkler is arranged on water intake just on the housing of position, such current enter tangent direction in the tangent direction of impeller and go out, both current point-blank, short by the time in hydroturbine cavity, using water flow energy coefficient is low, therefore efficiency is caused low, the drawback that hydraulic losses is large.In addition, existing hydroturbine is provided with bypass line and ordinary ball valve in outside, and the speed adjustment of impeller realizes by changing the bypass water yield by ordinary ball valve, and it is not compact that such structure also exists complete machine structure, the shortcoming that current adjustment is inconvenient.
Summary of the invention
Technical assignment of the present utility model is the deficiency for above present situation, provides a kind of working efficiency high, a kind of hydroturbine that hydraulic losses is little.
The utility model solves technological scheme that its technical problem adopts: a kind of hydroturbine of the present utility model, structure comprises in housing and arranges impeller, impeller is connected with output shaft with nut by key, output shaft is connected on bearing support by bearing, and the housing of hydroturbine high pressure water inlet arranges branch road water intake and nozzle; Branch road water intake connects bypass line, and bypass line is arranged on enclosure interior; Nozzle is inlayed on nozzle, and nozzle connects impeller cavity, and the housing of the axial centre position of impeller arranges housing central bore, and housing central bore is communicated with the middle part of bypass line.
Described branch road water intake arranges speed adjusting plate, and speed adjusting plate connects speed governing axle, and speed governing axle passes housing, and and sealed by two O type circles between housing, the speed control rod pin that rises is connected with speed governing axle.
Compared to the prior art a kind of hydroturbine of the present utility model, has following characteristics: the utility model design science, and by arranging housing central bore, when making work, current are long by the time at impeller cavity, and working efficiency is high, and hydraulic losses is little; By arranging the bypass line be integrated in hydroturbine housing, make volume of the present utility model little, size is little, easy to use.

Embodiment
With reference to Figure of description, a kind of hydroturbine is described in detail below.
A kind of hydroturbine of the present utility model, structure comprises in housing 1 and arranges impeller 2, and impeller 2 is connected with output shaft 4 with nut by key, and output shaft 4 is connected on bearing support 3 by bearing.The housing 1 of hydroturbine high pressure water inlet is arranged branch road water intake 9 and nozzle 5; Branch road water intake 9 connects bypass line 10, and it is inner that bypass line 10 is arranged on housing 1; Nozzle is inlayed on nozzle 5, and nozzle 5 connects impeller 2 cavity, and the housing 1 of the axial centre position of impeller 2 arranges housing central bore 11, and housing central bore 11 is communicated with the middle part of bypass line 10.During such work, current enter in the tangent direction of impeller cavity, and from Axial-running Out, enter bypass line, current are long by the time at impeller cavity, and therefore efficiency is high, and hydraulic losses is little.
Described hydroturbine is axial flow hydroturbine.
Described branch road water intake 9 arranges speed adjusting plate 6, and speed adjusting plate 6 connects speed governing axle 7, and speed governing axle 7 passes housing 1, and and sealed by two O type circles between housing 1, speed control rod 8 pin that rises is connected with speed governing axle 7.Speed control rod 8 can adjust the caliber size of branch road water intake, thus can change the water flow of impacting impeller 2, and then plays the effect of adjustment output speed.
In use, high pressure water enters housing 1 by water inlet elbow to the utility model, in the nozzle place of housing 1 and the shunting of branch road water inlet.Part water enters in impeller 2 cavity in housing 1 through nozzle 5, impact the blade of impeller 2, current are pooled to impeller central position along blade, then the housing central bore 11 on housing, enter into bypass line 10, converge with the water flow through from branch road water intake 9, then go out from bypass line outlet flow.Like this, water impact impeller, produces power by output shaft 4 externally output kinetic energy; Part water enters bypass line 10 by the branch road water intake 9 of housing (1), discharges this hydroturbine after mixing in the middle of bypass line with the water after impact impeller.The water flow of impacting impeller (2) can be changed by speed control rod (8) adjustment bypass caliber size, and then play the effect of adjustment output speed.
Hydroturbine of the present utility model compare in efficiency, performance and velocity compensation before hydroturbine be significantly improved, total performance improvement more than 20%, driving recovery speed can adjustment arbitrarily on a large scale.
