Is the impeller and the wind wheel the same thing?
The impeller also called working wheel. Only in centrifugal compressor of air power components. The most essential parts of the rotor. A wheel disc, a wheel cover and blade and other parts. The gas in the impeller blade under the effect of the increase of leaf rotation speed, gas by rotating centrifugal force, and the impeller. Flow, make it through the impeller after pressure was increased.
The impeller requirements are: (1) can give energy head larger; (2) the gas flows through the impeller loss should be small, the efficiency is the gas flows through the impeller to be high; (3) the gas outflow impeller parameters fitting, the flow loss is smaller when the gas flows through the back fixing element; (4) the impeller type the range of stable condition of district level or the performance curve and high efficiency wide. Often divided into closed, semi open and open impeller.
The wind turbine generator in the wind turbine, the impeller is composed of a hub and blades. The wind through the impeller, drives the impeller to rotate, which drives the generator to rotate, converting wind energy into electric energy. At this time, requirements of the rotating impeller is big enough to windward to extract enough energy from the wind; at the same time, in the wind when to be able to automatically adjust the blade windward angle, to avoid excessive force and mechanical damage.The physical world is sentient beings living in the world, which is just the beginning: the formation of the first wind wheel, and a turbine, then there appears at the end of the earth. The classic Jinlun, also said that in the hydro turbine wheel, the wind wheel on the earth; it is so, the wind wheel is the turbine is a nuclear explosion, magma, crust. Although the land is Jinlun, but there is still no sentient beings, love in the world. This world with love all sentient beings is sentient beings on certain days fall to the earth, there was no beast, ghosts, hell beings. That is when the world is just a form. No hell beings, then people more sinister, beast people do fall, then people do fall hungry, finally have hell beings. First appeared after the three thousand hell beings, the universe of 1,000,000,000 universes love in the world to complete, this world is not finished Become, and then continue to change with the karma of the sentient beings
