Abstract
The invention relates to a mechanism for controlling runner blades of a water turbine unit, which is characterized in that the mechanism comprises an oil-supply head and a blade adjusting servomotor. The blade adjusting servomotor is arranged outside a runner close to the oil-supply head, and is permanently connected with the rotor field spider of the unit. The piston of the oil-supply head is connected with one end of the piston of the blade adjusting servomotor. The other end of the piston of the blade adjusting servomotor is connected with one end of a force transfer shaft. The other end of the force transfer shaft is connected with the runner blades. As the oil-supply head and the blade adjusting servomotor are miniaturized and are arranged outside, and the invention is supported by a high precision manufacturing process, a complete oil collecting system and a complete leaked oil receiving system, turbine oil is ensured not to get into the runner; the operation oil pressure is improved; the structure of the invention is simplified; the size is significantly reduced; the cost is reduced; and oil pollution to downstream rivers is eliminated. In this way, the invention runs and is maintained conveniently and easily.
Description
Technical field
The present invention relates to a kind of water wheels unit runner, particularly a kind of mechanism that controls the water turbine set runner blade.
Background technique
At present, in technique known, change axial flow, tubular and diagonal flow type water pump---rotary wheel of water turbine blade servomotor is distributed on water pump---the rotor body inside of water turbine of oar, among the pressure oil of operation blade servomotor must be by just entering the blade servomotor behind the inside and outside oil pipe of lubricant receiver the A, B two oil pockets, make the left and right or upper and lower open and close of moving the blade of operating runner of its piston, the shortcoming that this known device exists is: lubricant receiver and the leakage of oil of runner blade root are serious, so that cause the serious oil pollution in river, downstream; Runner internal structure bulky complexization again in rotor body inside, is keeped in repair very difficultly, has also reduced the conveyance capacity of runner.The restriction Pump for Medium and Small Power Generating Set is used the possibility of rotary propeller type.
Summary of the invention
The present invention provides a kind of mechanism that can eradicate the control water turbine set runner blade of turbine oil receptor and the leakage of oil of runner blade root for solving the technical problem that exists in the known technology.
The technological scheme that the present invention takes for the technical problem that exists in the solution known technology is: a kind of mechanism that controls the water turbine set runner blade, comprise lubricant receiver and blade servomotor, described blade servomotor is positioned at the outside of described web, affixed with the rotor field spider of unit, near described lubricant receiver, the piston of described lubricant receiver links to each other with an end of described blade servomotor piston, the other end of described blade servomotor piston is connected with an end of force transmission shaft, and the other end of described force transmission shaft is connected with runner blade.
The present invention can also adopt following technological scheme:
The piston of the piston of described lubricant receiver and blade servomotor links to each other by the shock absorbing connector.
Described shock absorbing connector comprises many group leaf springs.
Affixed oil sump tank on the described lubricant receiver, affixed oil sump tank on the described blade servomotor.
The A of described lubricant receiver, B two chambeies communicate by its inner hole slot and flexible pipe with A, B two chambeies of servomotor.
Advantage and good effect that the present invention has are: operating oil pressure of the present invention is brought up to 20Mpa by traditional 2.5Mpa-6.3Mpa, therefore lubricant receiver, blade servomotor and corresponding pipeline size all can descend greatly, because the miniaturization and the exteriorization of lubricant receiver, blade servomotor also are aided with high-precision processing technology, complete collection, leakage of oil receiving system, guarantee that turbine oil can not enter runner inside, improved the operation oil pressure, made designs simplification, volume reduce, reduce cost greatly; Eradicated present situation again to the oil pollution in river, downstream.Make become very convenient and easy of operation and maintenance.

Fig. 2 is the structural representation of lubricant receiver of the present invention.
Among the figure: 1, lubricant receiver, 1-1, lubricant receiver housing, 1-2, lubricant receiver piston, 1-3, lubricant receiver A chamber, 1-4, lubricant receiver B chamber, 2, the blade servomotor, 2-1, blade servomotor piston, 2-2, blade servomotor A chamber, 2-3, blade servomotor B chamber, 3, force transmission shaft, 4, the shock absorbing connector, 5,6, flexible pipe, 7,8, oil sump tank.
Embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, Fig. 2, lubricant receiver 1 volume spy of the present invention is little, form by housing 1-1 and piston 1-2, housing 1-1 be fixed on the motor fore poppet or upper bracket motionless, lubricant receiver piston 1-2 is connected with blade servomotor piston 2-1 by shock absorbing connector 4, and is synchronized with the movement in it.Pass through inside hole slot, flexible pipe 5,6 through blade servomotor A, B two chamber 2-2, the 2-3 of lubricant receiver piston 1-2 from the pressure oil of lubricant receiver A, B two chamber 1-3,1-4.Affixed oil sump tank 8 on the described lubricant receiver 1, affixed oil sump tank 7 on the described blade servomotor 2.
Described shock absorbing connector 4 can transmit pressure oil, can alleviate the threat of the powerful jumping pendulum of set main shaft to the safe operation of lubricant receiver 1 again.
Described blade servomotor 2 be contained in generator rotor field spider above, install with electronic, generator amature and to be one, rotation together.The piston 2-1 of blade servomotor links to each other with force transmission shaft 3, force transmission shaft 3 is connected with the blade of runner again,---operation lift of water turbine---head along with water pump, when operating modes such as aperture change, the angle of runner blade needs correspondingly be changed, this change by external servomotor, lubricant receiver, cut that portions' covers such as shake connector, force transmission shaft finish jointly.
The invention provides a kind of with the blade servomotor by being moved to the generator outer end in the web, as much as possible near the external blade servomotor of former lubricant receiver position.The servomotor piston of outer postpone removes to connect the blade of runner by force transmission shaft, and force transmission shaft can or be closed with the unlatching of the left and right or upper and lower mobile control runner blade of the piston of blade servomotor like this.
Lubricant receiver diameter of the present invention is minimum, all adopts the manufacturing process and the technology of high oil pressure hydraulic pressure components and parts, and its seepage oil mass is few, and has designed reliable oil-collecting measure.Be being connected of lubricant receiver and blade servomotor piston to be undertaken by the shock absorbing connector of forming by many groups leaf spring, the common jumping of main frame pendulum is unlikely to be passed on the piston of lubricant receiver, the outer pressure oil that supplies is from the A of lubricant receiver, the pipeline in B two chambeies and A, B two chambeies of the straight-through blade servomotor of flexible pipe, because pressure oil can not enter runner inside, by blade leak downstream, the problem of oil extraction then can eradicate.
The present invention is installed in the blade servomotor on the left front or top support of unit, and its piston one end links to each other with lubricant receiver by the shock absorbing connector, and the other end links to each other with force transmission shaft, and force transmission shaft is connected with runner blade again.Because the blade servomotor is arranged in front left side or upside not only overhauls conveniently, and guarantees that pressure oil must not drain to runner inside.Its advantage is that total obtains simplifying except eradicating leakage of oil and to the pollution in river, also bringing great convenience to the power station maintenance.
