Abstract
Disclosed is a control system used for axial flow and cross flow size mixing water turbine paddle adjustment. The control system comprises an operation oil pipe and a rotary connector. The upper end of the operation oil pipe is connected with the rotary connector through a bolt. The rotary connector is connected with an oil inlet pipe and an oil outlet pipe. The control system further comprises a piston and an operation rod. A piston is located between a water turbine spindle and a generator spindle, so that an upper oil cavity and a lower oil cavity are formed. The piston and the operation rod are combined through a nut. The operation rod is connected with the lower end of the operation oil pipe through a bolt. An inner channel and an outer channel of the rotary connector are connected with an inner oil cavity and an outer oil cavity of the operation oil pipe and are sealed through seal rings. The inner oil cavity and the outer oil cavity of the operation oil pipe communicate with an upper oil cavity and a lower oil cavity of the piston correspondingly. The control system is simple in structure, can bear high rotation speed and high oil pressure and solves the oil leakage problem effectively.
Description
Technical field
The hydraulic turbine paddle regulation and control system the present invention relates to a kind of axle stream, through-flow are sized mixing.
Background technology
Traditional axle stream, through-flow adjust impeller type turbine paddle control system to transmit pressure oil using Babbitt alloy oil head, and are delivered to piston upper and lower cavity by operating oil line.In traditional blade control system, piston is located at runner body position, therefore operating oil line is longer, is also easy to produce in main shaft during work and rocks, so as to affect job stability.
There is, complex structure low using rotating speed in traditional paddle control system, difficult in maintenance to wait not enough, system has oil leak, has greater environmental impacts.
The content of the invention
Complicated to solve hydraulic turbine paddle Control system architecture described above, the problems such as difficult in maintenance, oil leak, the present invention provides a kind of simple structure, No leakage, can bear high oil pressure, high rotating speed, safe and reliable oil pressure conveying control system.
The present invention is achieved by the following scheme.
A kind of control system of hydraulic turbine paddle regulation of sizing mixing for axle stream, through-flow, the control system includes operating oil line and swivel joint, and the operating oil line upper end is bolted with the swivel joint, the swivel joint be connected into and out of oil pipe.The control system also includes piston and action bars, the piston is located at hydraulic turbine main shaft and generator shaft centre position, so as to form upper and lower two oil pockets, and with the action bars by nut handle and, the action bars is bolted with the lower end flanges of the operating oil line.
As preferred, the swivel joint has inside and outside two passages, the operating oil line has inside and outside two oil pockets, and the internal channel of the swivel joint is connected with the interior oil pocket of the operating oil line, and the outer tunnel of the swivel joint is connected with the outer oil cavity of the operating oil line.
Further, when the inside and outside passage of the swivel joint is connected with the inside and outside oil pocket of the operating oil line, sealed by sealing ring.
Further, the inside and outside oil pocket of the operating oil line is communicated respectively with the upper and lower oil pocket of the piston, so as to control piston up-down.
Preferably, the swivel joint carries oil leak interface, a small amount of oil leak of the rotation can flow back to speed regulator, reach zero leakage by the oil leak interface.
During work, hydraulic oil enters the upper and lower oil pocket of piston by the inside and outside oil pocket of swivel joint and operating oil line, by the oil pressure cntrol piston up-down in the upper lower oil cavitie of control, so as to drive action bars to move up and down, finally realizes the regulation of hydraulic turbine blades.
Beneficial effects of the present invention are mainly manifested in：（1）High rotating speed, high oil pressure：High rotating speed can be born using swivel joint, and high oil pressure can be born.
（2）Environmental protection：By runner assemble in liquid oil make solid-state butter into, it is to avoid liquid oil leaks into tail water；Swivel joint carries oil leak interface, a small amount of oil leak can be flow back to into speed regulator.
（3）Stability is high：Operating oil line length is shorter, strengthens the stability of system work.
（4）Simple structure, install, it is easy to maintenance：Operating oil line top and swivel joint with bolt handle and, bottom and piston also use bolt handle and, it is easy for installation；It is easy to maintenance without the need for dismantling other parts when changing swivel joint.
Description of the drawings
Fig. 1 is hydraulic turbine paddle control system architecture figure.
Fig. 2 is swivel joint and operating oil line coupling part enlarged drawing.
Specific embodiment
Below in conjunction with the accompanying drawings the invention will be further described.
With reference to Fig. 1, Fig. 2, a kind of control system of hydraulic turbine paddle regulation of sizing mixing for axle stream, through-flow, the control system includes operating oil line 6 and swivel joint 2, and the upper end of the operating oil line 6 is bolted with the swivel joint 2, and the swivel joint 2 is connected with oil pipe 1.The control system also includes piston 14 and action bars 17, the piston 14 is located at hydraulic turbine main shaft 16 and the centre position of generator shaft 11, so as to form upper and lower two oil pockets 12,15, and with the action bars 17 by 13, nut and, the action bars 17 is bolted with the lower end of the operating oil line 6.
The swivel joint 2 has inside and outside two passages 7,4, the operating oil line has inside and outside two oil pockets 10,9, the internal channel 7 of the swivel joint 2 is connected with the interior oil pocket 10 of the operating oil line 6, and the outer tunnel 4 of the swivel joint 2 is connected with the outer oil cavity 9 of the operating oil line 6.
When the inside and outside passage 7,4 of the swivel joint 2 is connected with the inside and outside oil pocket 10,9 of the operating oil line 6, sealed by sealing ring 5,8.
The inside and outside oil pocket 10,9 of the operating oil line 6 is communicated respectively with the upper and lower oil pocket 12,15 of the piston 14, is moved up and down so as to control piston 14.
The swivel joint 2 carries oil leak interface 3, and a small amount of oil leak of the swivel joint 2 can flow back to speed regulator, reach zero leakage by the oil leak interface 3.
During work, hydraulic oil enters the upper and lower oil pocket 12,15 of piston by the inside and outside oil pocket 10,9 of swivel joint 2 and operating oil line 6, moved up and down by controlling the oil pressure cntrol piston 14 in upper and lower oil pocket 12,15, so as to drive action bars 17 to move up and down, the regulation of hydraulic turbine blades is finally realized.
