Compared with the prior art, the utility model, the advantage that has is, simple structure, and it is convenient to install, and less to the engineering volume that traditional equipment goes on reequiping, the water velocity can be accelerated to the guide plate, improves the work efficiency of the hydraulic turbine.
Description
Technical field
The utility model relates to turbine equipment field, particularly relates to a kind of hydroturbine water intake passage.
Background technique
Water turbine is the dynamic power machine of rotating mechanical energy the transformation of energy of current, and it belongs to the turbomachinery in fluid machinery.Before and after B.C. 100 years, just there are the blank of water turbine---water wheels, for irrigating by lifting water to a higher level with a water pump, etc. and drive grain processing apparatus in China.Modern water turbine then great majority is arranged in water power plant, is used for driving electrical power generators.In water power plant, the water in upper pond guides water turbine into through aqueduct, and promote rotary wheel of water turbine and rotate, drive electrical generators generates electricity.The water finishing merit then by tail water pipeline discharged to downstream.Head is higher, flow is larger, and the output power of water turbine is also larger.
Water turbine and subsidiary engine are important hydroelectric facilities is the requisite constituent element of hydroelectric power industry, be make full use of clean reproducible energy to realize energy-saving and emission-reduction, reduce the visual plant of environmental pollution, the development scale of its technical development and China's hydropower industry adapts.Under the brute force of Electricity Demand pulls, China's water turbine and subsidiary engine manufacturing enter the fast-developing phase, and its economic scale and technical merit are all significantly increased, and China's water turbine manufacturing technology reaches advanced international standard.
The current of early stage impulse turbine are when impacting blade, and kinetic energy rejection is very large, and efficiency is not high.1889, American engineer Pei Erdun invented Pelton wheel, and it has fairshaped convergent nozzle, flow energy can be changed expeditiously into the kinetic energy of high-speed jet.Water turbine (whole section can all not wanted, this section above 80% all out-of-date, be all substituted.Very old data, reference value is little, so this section is removed in suggestion) early 1980s, what the Pelton wheel that single-machine capacity is maximum was in the world loaded on Norway knows western horse power station, and its single-machine capacity is 315 megawatts, 885 meters, head, rotating speed is 300 revs/min, puts into operation in 1980.The Pelton wheel that head is the highest is loaded on Austrian bad plucked instrument Keshan power station, and its single-machine capacity is 22.8 megawatts, and rotating speed 750 revs/min, head reaches 1763.5 meters, and nineteen fifty-nine puts into operation.
Water turbine can be divided into impulse turbine and the large class of reaction turbine two by working principle.The runner of impulse turbine is subject to the impact of current and rotates, and in working procedure, the pressure of current is constant, mainly the conversion of kinetic energy; The runner of reaction turbine is subject to the reaction force of current and rotates in water, and in working procedure, the pressure energy of current and kinetic energy all change, but the conversion of mainly pressure energy.
Current use is axial flow hydraulic turbine comparatively widely, and its intake tunnel of axial flow hydraulic turbine is related to the working efficiency of water turbine, and traditional immersion passage does not have acceleration to current, and the working efficiency of water turbine is not high in the course of the work.
In sum, for the defect of prior art, a kind of hydroturbine water intake passage of special needs, thus solve above-mentioned problem.
