Embodiment
With reference to Figure of description, a kind of high-efficiency axial flow hydroturbine with spring card guiding is described in detail below.
A kind of high-efficiency axial flow hydroturbine with spring card guiding of the present utility model, it is aluminum casting that structure comprises housing 1, and point left and right two-part, time fit, are connected with bolt by sealing joint strip.Impeller 9 is connected with output shaft 5 by key, nut, and then entirety is connected with housing 1 with bolt, nut.By-pass port 7 connects mixed water cavity 10, and mixed water cavity 10 connects water outlet 3.By-pass port 7 is arranged in housing 1, and near water intake 4, the volume that so built-in by-pass port just can reduce whole hydroturbine is little, and compact structure is easy to adjust.Water resistant plate 8 is installed to by-pass port 7 place of housing 1 by drive fit, and is connected to speed governing axle 2 by key and nut, and speed governing axle 2 reaches outside housing, can carry out speed regulating, manually or automatically can, speed governing is very convenient.The utility model, when by-pass port is closed, can form sealing by inside cavity hydraulic pressure.When speed governing axle 2 speed governing changes by-pass port 7 bore, due to the effect of hydraulic pressure, increase water resistant plate 8 and the frictional force of by-pass port 7, make water resistant plate 8 carry out minor adjustments, conservative control hydroturbine rotational velocity.
Spring card 6 is arranged on above the hydroturbine cavity near by-pass port 7, is connected with housing 1 by bolt, bearing pin etc.Spring card 6 with water impact, can carry out pressing, stretching motion, so just can ensure the guidance quality of guide channel.
Spring card 6 structure consists of the connection pin 13 that rises coil tension spring 12 and water conservancy diversion card 14, is then arranged in hydroturbine chamber by the pin 11 that fixedly rises.Spring card 6 is pre-assembling structure, and water conservancy diversion card need be stuck in reserved water conservancy diversion restraining groove, and entirety is stainless steel.Operationally, after current enter hydroturbine cavity by hydroturbine water intake 4, because current are flushed on water conservancy diversion card 14, coil tension spring 12 can stretch with hydraulic pressure.When hydroturbine carries out speed governing, due to the sluicing effect of by-pass port 7, change the water pressures of water conservancy diversion card 14 both sides, under coil tension spring 12 acts on, water conservancy diversion card 14 adjustment can adapt to streamflow regime automatically, makes water flow energy effectively along impeller tangential impact impeller, improves the utilization ratio of water flow dynamic energy.
The housing of the axial centre position of described impeller 9 arranges housing central bore 15, and housing central bore 15 is communicated with mixed water cavity 10.
Described water resistant plate 8 lower surface adopts abrasive rubber material.In housing, current (hydraulic pressure) are larger, and water resistant plate 8 sealing is better.
In use, hydroturbine entirety is bolted in the collateral support of Winding machine the utility model, and output shaft 5 is connected to the mandrel on the reel assembly of Winding machine by bearing.High pressure water enters housing 1 by water intake 4, and when just having started water inlet, by-pass port 7 is closed, and water first enters impeller 9 through spring card 6.Along with speed governing, by-pass port 7 is opened, and a part of water has just flowed to by-pass port 7.At this moment, the water impacting spring card 6 under constant flow of inlet water is just few.Water has lacked, the pressure acted on spring card 6 has just diminished, and the coil tension spring 12 on spring card 6 can stretch out a part along with stressed reduction naturally, and coil tension spring 12 1 is stretched out, water conservancy diversion card 14 has just diminished with the gap of impeller 9, and the water flow entered in impeller 9 chamber has also just diminished.So just can complete the adjustment of the water flow into impeller 9 delicately.
When water resistant plate 8 seals up by-pass port 7 completely, current all enter housing 1 impeller cavity, under spring card 6 leads, water flow energy tangentially direction enters impeller cavity impact impeller 9, and current along blade from outside to inside, are pooled to impeller central, and enter mixed water cavity 10 along impeller shaft to by housing central bore 15, this increased periods water impact time, improve water application efficiency, the power of generation is by output shaft 5 externally output kinetic energy.When water resistant plate 8 opens by-pass port 7, a part of water can enter mixed water cavity 10 by the by-pass port 7 of housing 1, discharges this hydroturbine with the water impacting impeller after mixed water cavity 10 mixes through water outlet 3.
The function that structure of the present utility model can realize:
(1), the setting of hydroturbine initial velocity, by rotating speed governing axle, changing bypass that water resistant plate formed and to make a slip of the tongue footpath, the mouth of a river, the initial speed of hydroturbine can be set easily.
(2), velocity compensation, in reel sprinkling irrigation machine, because PE pipe has multilayer, PE pipe is different at its swing diameter of the different numbers of plies, for ensureing the linear velocity recovery that PE pipe can remain constant, carries out velocity compensation with regard to needs between each layer PE pipe.The utility model speed governing is sensitive, can facilitate and realize velocity compensation function accurately, and driving recovery speed can adjust arbitrarily on a large scale, and working efficiency is high.
