Description
Technical field
This utility model relates to a kind of water-use for hydropower turbine.
Background technology
The hydraulic turbine is the dynamic power machine energy of current being converted to rotating mechanical energy, and it belongs to the turbomachinery in fluid machinery.Before and after B.C. 100 years, China has occurred as soon as the blank water wheels of the hydraulic turbine, is used for irrigating by lifting water to a higher level with a water pump, etc. and drive grain processing apparatus.The modern hydraulic turbine in then great majority are arranged on power station, is used for driving electrical power generators.In power station, the water in upper pond guides the hydraulic turbine into through aqueduct, promotes rotary wheel of water turbine to rotate, drives electrical power generators.The water finishing merit is then arranged downstream by tail water pipeline.Head is the highest, flow is the biggest, and the output of the hydraulic turbine is the biggest.
The hydraulic turbine can be divided into impulse turbine and the big class of reaction turbine two by operation principle.The runner of impulse turbine is rotated by the impact of current, and in work process, the pressure of current is constant, mainly the conversion of kinetic energy；The runner of reaction turbine is rotated by the counteracting force of current in water, in work process current pressure can and kinetic energy all change, but mainly pressure can conversion.The hydraulic turbine is a kind of dynamic power machine that water can be converted to mechanical energy.In most of the cases, by electromotor, this mechanical energy being converted to electric energy, therefore the hydraulic turbine is water power calculation and electric energy production service.Pump turbine is mainly used in hydroenergy storage station.When power system load is less than base load, it can be used as water pump, utilizes providing auxiliary power ability, and reservoir draws water upper pond downstream, stores energy with potential energy form；When system loading is higher than base load, can be used as the hydraulic turbine, send electric power to regulate peak load.Therefore, pure pump-storage plant can not increase the electricity of power system, but can improve the performance driving economy of thermal power generation unit, improves the aggregate efficiency of power system.
Current existing hydraulic turbine structure is complicated, and structural stability is poor, and generating efficiency is the highest.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of compact conformation, and stable, generating efficiency is high, water-use for hydropower turbine easy to use.
For solving the problems referred to above, this utility model adopts the following technical scheme that a kind of water-use for hydropower turbine, including casing, spiral case, main shaft and bearing, described spiral case is located at outside casing, described main shaft is located in casing, described bearing is located on main shaft, described bearing is fixing with casing to be connected, described bearing is connected with main axis, the first runner and the second runner it is also equipped with on described main shaft, described first runner connects with spiral case, it is provided with water channel in described casing, described first runner is connected by water channel and the second runner, on described first runner, servomotor is installed, below described second runner, lower servomotor is installed, bottom described second runner, draft tube is installed.
As preferably, described first runner and the second runner are connected with spindle drive respectively, keep Stability Analysis of Structures reliable.
As preferably, the curved setting of described water channel, holding current are the most smooth.
As preferably, described spiral case is connected with casing sealing, keeps sealing structure effective.
As preferably, described spiral case diameter is more than 50cm, keeps the water yield sufficient.
The beneficial effects of the utility model are: the first runner of setting and the second runner can run the stability improving main axis simultaneously, effectively promote generating efficiency, upper servomotor and lower servomotor facilitate regulating water flow and angle of current, promote generating efficiency, and draft tube keeps draining unobstructed.
