This year China will become the world's largest producer of wind turbines

Last year, the Global Wind Energy Council (GlobalWindEnergyCouncil / GWEC) Secretary-General SteveSawyer said that in 2009 China will become the world's largest producer of wind turbines, which will rapidly developing field of renewable energy brought new changes. According to the agency's data, although in 2007 the global wind power accounted for only 1% of the electricity supply, but the rapid development of wind power by 2020 will meet 12% of world electricity demand, and this will go a long way to control global warming benefits.

To deal with global climate change, reduce greenhouse gas emissions, renewable energy sector has attracted more and more and more investment, especially wind power, which provides energy than solar power and bio-energy and other renewable sources of energy to many. According to Sawyer introduction to the end of 2009, China's wind power capacity from the current 400 million to about瓦提high 10 million kilowatts, is the world market of more than half of capacity. 2007 World Added 1700-1900 wind generation capacity 10,000 kilowatts, with a total generating capacity of the fan more than 90 million kilowatts by 2008, 10000w wind generators global fan power generation capacity will be more than 100 million kilowatts.

According to Sawyer said the two Chinese fan wind turbine manufacturer and Huarui Jinfeng have been made in 2009 and 2010 large-scale export scheme, there is no Chinese export fans, but once the Government to promote exports will be the rapid development of the members of this Council (more than 50 countries, more than 1,500 enterprises) on the Chinese fan impact on the world market should be prepared.

At present, the world's largest fan manufacturers are Denmark's Vestas, the other more important producers are Spain's Gamesa, General Electric of the United States, India's Suzlon and Germany's Enercon

150KW wind turbine aircraft braking systems

Xinjiang Wind Energy Company Dabancheng existing wind farm and wind turbine Nets 14 Units, 13 Units equipped with hydraulic braking systems, by running over the past year, we found that 60% of the wind turbine from the hydraulic system failure, but at operation as long as a good grasp of maintenance work can be done on prevention, while better safeguarding Ways With even a failure can be found as soon as possible and timely treatment and to exclude, so greatly reduces the wind turbine downtime, improve a wind turbine operating efficiency. The following wind turbine hydraulic braking systems and maintenance of the structure of the principle methods of introduction are as follows:

First, the braking body

150KW wind turbine brake body mainly by the hydraulic system, disc brakes, damping plate when the tip is composed of three parts
