Abstract
The utility model relates to a hydraulic control multi-nozzle device for an impulse water turbine formed in a method that an impact water turbine set is composed of a special governor for a microcomputer, nozzles which are completely controlled by hydraulic pressure and a flow diverter. When the utility model loads off, the utility model can quickly change the direction of water jet without rushing on the bucket type water turbine, and meanwhile, the nozzles can be slowly shut without generating over hydraulic pressure in a diversion conduit, so the utility model can safely and smoothly satisfy the requirements of power quality and guarantee of regulation. The utility model has simple structure and convenient maintenance management and lays a solid base for the development of high automation.
Description
Technical field
The utility model belongs to the manipulating nozzles and the control gear thereof of impulse turbine in the hydroelectric power unit.
Background technique
Impulse turbine is to belong to the high head unit, comes exerting oneself of regulating and controlling hydraulic generator unit by nozzle, and is long to the diversion pressure steel tube of high head unit, the rated speed height of water turbine.For guaranteeing safe operation, to adopt multiinjector on the one hand, adjusting jet diameter size, the water wheels rotating speed is quickened, unit requires nozzle to close and wants fast when removal of load on the other hand, overrun in order to avoid produce unit, want slow, destroy diversion pressure steel tube to avoid producing water hammer but diversion pressure steel tube requires nozzle to close again.People are for solving this contradiction, adopted the method for control nozzle and flow diverter, the method of control nozzle and flow diverter has the mechanical type lever of employing, cam etc. at present, earlier by flow diverter is very fast jet is departed from runner when removal of load, raise to prevent generating unit speed, the while is shut-off nozzle lentamente, so that not producing big hydraulic pressure, diversion pressure steel tube do not rise, but because the operation of mechanical lever, cammingly is complicated, easy break-down is so need to improve.
Summary of the invention
The purpose of this utility model provides a kind of impulse turbine hydraulic control multiinjector device that adopts the microcomputer special governor to realize.
The technical solution of the utility model is equipped with nozzle 1, flow diverter 11 directly to Pelton wheel at the water outlet of diversion steel pipe 17 as shown in Figure 1.According to payload, drop into nozzle 1 and flow diverter 11 numbers arbitrarily by 1,2,4 modes, the oil pipe connection mouth 8,9 of nozzle 1 and the oil pipe connection mouth 12,13 of flow diverter 11 are connected with microcomputer special governor 15 oil gears by oil pipe 16.
The technological scheme of nozzle 1 and flow diverter 11 as shown in Figure 2, left end at nozzle 1 is a nozzle carrier 10, in the middle of the nozzle carrier 10 is water intake, nozzle 1 right-hand member is equipped with nozzle cover 2, be equipped with nozzle 3 on the nozzle cover 2, the core of nozzle 1 has nozzle needle axle 4, the inside left end of nozzle needle axle 4 is feedback tapered sleeves 5, right-hand member is a nozzle needle 6, and feedback tapered sleeve 5 links into an integrated entity with nozzle needle 6, and feedback tapered sleeve 5 cooperates with the nozzle needle feedback rod 7 that is positioned on nozzle carrier 10 sides, when feedback tapered sleeve 5 moves, nozzle needle feedback rod 7 just moves up and down, and information transmission to microcomputer special governor 15, is controlled the oil pipe connection mouth 8 of nozzle carrier 10 sides, oil pressure in 9 the pipe, promptly control nozzle needle 6 mobile positions, nozzle needle 6 cooperates with nozzle 3, and control water outlet jet diameter size is until closing.
Flow diverter 11 is fixed on nozzle carrier 10 and the nozzle cover 2, oil pipe connection mouth 12 on the flow diverter 11,13 are connected with microcomputer special governor 15 oil gears, the servomotor 14 of microcomputer special governor 15 control flow diverters 11, when proper functioning, servomotor 14 is in water jet diameter top all the time, does not interfere jet.The adjustment that impulse turbine is exerted oneself realizes by changing the water jet diameter, Flow-rate adjustment when nozzle needle 6 is responsible for normal the operation, when unit needs removal of load, if nozzle needle 6 is closed diversion steel pipe 17 internal pressures are sharply increased, produce water hammer, destroy steel pipe, if nozzle needle 6 is slowly closed, to cause the transient state speed of unit to rise, and produce unit and overrun.Therefore the utility model is when needing removal of load, and microcomputer special governor 15 oil gears are pressed corresponding oil pipe connection mouth fuel feeding.At first, make the servomotor 14 of flow diverter 11 change the water jet direction rapidly, close nozzle needle 6 more slowly simultaneously, make it safety and steady ground and satisfy the quality of power supply and regulate the requirement that guarantees.
The utility model is a kind of multi-jet turbine of all-hydraulic control, and is simple in structure, and repair and maintenance is convenient, and it is the development of high automation degree direction, has established solid foundation.

Embodiment
Pressing such scheme implements, for prolonging the unit maintenance phase, strengthen the reliability of nozzle, therefore, do not adopt spring in the nozzle 1, to be stabilized in a certain aperture motionless for nozzle needle 6 when unit moved under the situation of steady load, because microcomputer special governor 15 main control valves lap up and down make maintenance certain pressure in the nozzle needle operating cavity just, its size of the power of closing that is produced by this pressure just equates with the water active force that nozzle needle 6 heads trend towards opening, so nozzle needle 6 can be stabilized on the equilibrium position that this and external load adapt, and satisfies the quality of power supply.
