Description

Can drive in the water turbine blade and adjust structure
Technical field
The invention belongs to turbine technology field, is specifically related to can drive in a kind of water turbine blade adjust structure.
Background technique
Water turbine paddle adjustment technology all adopts the outside pressure oil that supplies both at home and abroad at present, realizes transition fixing and rotating part by lubricant receiver, and high pressure oil is passed to piston and the oil cylinder that is arranged in paddle wheel hub internal interface power device, regulates the paddle purpose to reach.And the blade of conventional design adjustment structure has only servomotor in wheel hub inside, as shown in Figure 1, its working principle is that the oil of outside oil tank charges into accumulator by compressed-oil system, supply with digital valve by the accumulator oil pipe line, by measuring and given signal input PLC, send the operation electrical pulse by PLC and move opening of digital valve, close oil circuit, again pressure oil is sent to the main shaft operating oil line of rotation by fixing oil dispenser (lubricant receiver) with rotation, deliver to the servomotor of rotary wheel of water turbine by the main shaft operating oil line, realize the adjustment of paddle at last by the to-and-fro motion of servomotor.Need very big operating work owing to adjust paddle, and this conventional structure is because oil pressure is low excessively, must adopt bigger fuel delivery could realize the transmission of big operating work, so the oil sump tank that need are several cubic metres and the forced oil device of 10-100KW provide the supply of pressure oil, and the larger-diameter pipeline road of needs, owing to rotate lubricant receiver system sealing and the lubricated supply that can't realize high oil pressure with fixedly oil transportation, therefore the oil pressure of runner operating cyloinder is restricted, generally be designed to 2.5MPa, and the volume of lubricant receiver and servomotor is all very big.In addition, the blade of conventional design is adjusted structure, and its wheel hub inside is full of pressure oil, and therefore general fuel tank trapped fuel amount exists and run oil leakage phenomenon, and environment is impacted more than 3 tons.
Summary of the invention
The purpose of the invention provides can drive in a kind of water turbine blade adjusts structure, to adjust the inside that pressure energy storing system, operation system, executive system that paddle uses all are installed in the paddle wheel hub, solved that the outer liquid pressure energy is bad in the sealing that is subjected to rotation to occur in can the original paper transmittance process, the problem of leakage of oil and the problem that rotary seal transmission operation oil pressure is restricted.
The concrete technological scheme of the invention is as follows: can drive in the water turbine blade and adjust structure, comprise the pressure energy storing system, operation system and executive system, wherein the pressure energy storing system comprises fuel tank, accumulator, oil pump and pressure automatic control link, operation system comprises digital valve and displacement transducer, executive system comprises operation link arm and blade servomotor, the pressure energy storing system, operation system and executive system are installed in the inside of blade wheel hub, accumulator, oil pump, the horizontal concentric arrangement of digital valve three also directly is connected to the blade servomotor by pipeline road, and the electric signal of blade is drawn Access Control System by the inner chamber cable slip ring of main shaft and controlled.
Can drive the adjustment structure in the water turbine blade adopts the safety voltage that is lower than 36V to power and the signal transmission.
The beneficial effect of the invention: adjust structure with the external enwergy drive-type paddle of prior art and compare, the invention will be adjusted the pressure energy storing system that paddle is used, operation system, executive system all is installed in the inside of paddle wheel hub, paddle electric returns feedback signal and speed regulator operation signal and inserts slip ring by main shaft inner chamber cable and draw, because will design core transfers to runner boss inside and adopts closed tank, make the inner non-oil-filled body of wheel hub the leakage of oil problem can not occur running, and then solved the outer liquid pressure energy and be subjected to sealing and lubrication problem in can the original paper transmittance process to rotation, solved because of restriction fixing and rotary seal transmission operation oil pressure, cancelled pipeline and the complicated lubricant receiver structure of operating oil line and the outside compressed-oil system of main shaft simultaneously, made design, make, installation and maintenance all obtain simplifying; The safety voltage of 36V is powered and the mutual transmission of electric power signal because employing is lower than, and has eliminated because of the influence of wheel hub internal-external temperature difference generation dewfall to electrical properties; Employing should interiorly can structural design can rise to 16-25MPa with oil pressure in addition, so the operation oil mass is 1% of routine.Structural volume also has only 5% of original structure volume.
The invention also has economic benefit significantly, can reduce 100,000 yuan with 3000kw hydraulic turbine generator comprehensive Design expense; Installation fee can reduce 100,000 yuan; Make processing charges and can reduce 250,000 yuan; Save 150,000 yuan of 5 tons of minimizing expenses of steel (fuel tank pipeline valve); Corollary equipment takes 50,000 yuan; Oil reduces 70,000 yuan of investments; Forced oil device power consumption saving 22kw*5000h*0.5 unit=50,000 yuan; Add up to 770,000 yuan.Domestic 1-3 ten thousand kw units are used comparatively extensive, and every cover can be saved 1,500,000 yuan expense, and the annual quantity of producing in the whole nation has 300 covers, can reduce by 4.5 hundred million expense and energy consumption.Enterprise and social benefit are considerable, and environmental protection and energy-saving and emission-reduction are also had wide significance.
In sum, interior can the driving of paddle adjusted designs simplification, and the economy and society benefit is huge, and technical feasibility has very big research promotion meaning.This technology can enlarge blade adjustments and the association area of using with the wind-powered electricity generation machine, has practicability widely, is that water turbine is made the field significant innovation.
