Mechanical Seals Manufacturer In China

In their side and overhead, are tall, they are more numerous than the wind generators. Huge fan straight sweep the sky, see people dizzy.

Here is the Asia’s largest wind farm – Huitengxile wind farm.

Located in the Inner Mongolian Plateau, is also a vent, its name in Chinese means “cold ridge.” Can be seen here, rich in wind resources.

In 1996, construction of wind power generator farms here. According to the plan, where to build a million-kilowatt wind power base. At present, there have been Huaneng, Datang, Huadian, north Beijing to the China Guangdong Nuclear and other seven major state-owned enterprises stationed, with a total installed capacity of more than 100 million kilowatts.

“If all the running, the electricity generated each year in 300 million degrees.” Huitengxile North United Power wind farm, said head of the farm Zhi.

Li Zhi in the wind farm has been done for 14 years, he was responsible for management, including 12 kinds of models with 132 wind turbines and two substations. “First Financial Daily” reporters, when the aerial of the mobile phone is always ringing off the hook, and he commanded the men each time, what materials to use to repair parts which can be more than save some money down.

“No Do not do that. Once the limit of electricity has been cut away the net profit ah.” He said that because of limited power, this family tradition electric field on the loss of nearly 400 million profit.

“A few years ago has been good, limited power is not obvious.” Zhi told reporters, before 2008, Huitengxile wind power companies only 5 family tradition, the scale is also not very high. But two years ago and last year, wind power scale soaring. Today, seven companies are scaling up, “the speed of wind power generator expansion has far exceeded the speed of power grids.” He said.

Outstanding issues every year. Each year in October to the second year in April, a full six months, Zhi hearts are tugging. He said: “The fear is that the dispatch room the night before the power company sent a text message. Text messages telling me how much power the next day to allow delivery. This year, limit such messages more and more power. Restrictions on electricity up to the small wind turbines time is a kilowatt not let you send. ”

This family tradition Zhi management field and other different. 132 wind turbines, some use of a longer time, are already aging and damage. “In winter, in temperatures of minus 40 degrees, the stop loss is very great.” Zhi told reporters, “If the limit of power 5 hours, the old machine stopped, and then spend 78 hours may have not start up.”

Family tradition in this field reporter dispatch room of the table to see a piece of paper that said more than a dozen stations have been number of wind turbines can not stop. “Can not stop, and basically that old machine.” Dispatchers said.

Huadian Huitengxile Wind Farm Safety Minister Liang Zhenfei too bad the same day. He told reporters that the task based power generation target assigned every year, and even that the average utilization of wind turbines can not be less than 97%.

This allows Liang Zhenfei very difficult, after all, is not how much power he made the decision – the decision to God how much wind, how much electricity the power company decided to send, and he can do is to safeguard the 120 “big windmill.”

Walking in the Gobi desert is boring, but the western end of Hexi corridor Jiuquan miles within the Gobi Desert, jumped into the eyes lined windmill generators, like an oasis, so feel suddenly heated up. Wind power companies in Gansu Province WANG Ning Bo, director of an interview with reporters today, said, with the gradual expansion of Gansu scale windmill power, windmills all over the Gobi and deep eco-tourism benefits are prominent features.
WANG Ning Bo introduced Jiuquan, Gansu provincial government use for the mountains north and south, central part of the flat, open desert, the natural formation of two mountains and one trough, a geographical advantage of what wind channel, launched in 2009, planning and construction of 10 million kwh of China’s first domestic wind power bases, the Shanghai World Expo Gansu Museum of wind power “model” came from this base, aims to introduce clean energy in today’s and future society, Gansu Province and even China to adjust energy structure, energy conservation significance produced, so that Gansu’s resources more fully into play, and to promote the development of equipment manufacturing industry, thus changing pattern of economic development and structural adjustment, the final push to improve people’s livelihood.
Gansu is a country rich in wind power generator resources, one of the provinces, according to “Wind Power Project in Gansu Province Planning Report” and the results of the latest analysis of meteorological departments, the province’s 10-meter high wind energy resource of about 237 million kilowatts of total reserves, total reserves of wind energy fifth in the country, occupies the country can be developed using the third, the annual effective wind energy reserves in more than 800 kwh per square meter.
August 1995, Gansu Provincial Power Company yumenzhen about 12 kilometers southeast of building a 30-meter-high wind towers, and began to wind power generator development for the purpose of wind resource monitoring. After 10 years of development, the first wind farms in Gansu Province from the initial stage of 01,200 kilowatts and gradually developed into a total scale of 110 thousand kilowatts of large-scale wind farms.
Wang Ning Bo said that wind power installed capacity in Gansu this year will reach 5.25 million kilowatts, compared with traditional thermal power could reduce carbon dioxide emissions by around 13 million tons, sulfur dioxide emissions by 15,000 tons, about 10,000 tons of dust emissions, the annual power generation 11.5 billion kwh, an alternative thermal power 3.7 million tons of standard coal in savings, annual savings of more than 10 million cubic meters of water resources, contributed to the ecological environment.
In an interview with reporters in Gansu, Hexi Corridor, Gansu Jiuquan many times through the lot of wind power base, is pleased to stop every time, and many strangers together enjoy the patchwork of Windmill pedestrian woven mesh picture, which shows vitality, feeling so dull as the original windmill “whining” of the rotation disappeared.
The windmill height of 44 meters, from the three long leaves composed of more than 20 meters, generators export voltage 690 V, step-through box-type transformer of 10 KV, 110 KV boost after the grid. Check the many Jiuquan base of wind power company CEOs, has expressed confidence on wind power development. Wang Ning Bo said, according to wind power development plan in Gansu Province, since 2020, expanded to 40 million kilowatts installed capacity over that time, Hexi Corridor has become the world’s largest wind power base.

Today, Asia’s first offshore wind power turbines market, focusing the professional platform for “2010 Shanghai International offshore wind power and wind power industrial chain Conference and Exhibition” opened in Shanghai. Including the Sheraton Shanghai Hongqiao General Assembly held at the Pacific Hotel and exhibition held in Shanghai International Exhibition Center to display area of 10,000 square meters.
National Energy Board new energy and renewable energy Secretary, Wang Jun, Vice Minister of Petroleum and Energy of Norway, the NPC Environmental and Resources Protection Committee Mao Rubai, China Association of Resources Comprehensive Utilization of Renewable Energy Professional Committee of General Li Junfeng, China International Trade Promotion Committee Vice Chairman Wang Lie Shanghai Branch Shanghai Development and Reform Commission Secretary Zhou Qiang, Sinovel Technology (Group) Co., Ltd., Han Junliang,  up wind power generators business unit president and other leaders in the General Assembly speech and cut the ribbon.
After 10 years of development, the world’s offshore wind power technology is becoming mature. National Energy Administration, deputy director of renewable energy sources recently said Shi Lishan, to speed up the construction of offshore wind power, the basic conditions, offshore wind power will be the focus of future development of wind power. National Energy Board has in recent days to Liaoning, Hebei, Tianjin, Shanghai, Shandong, Jiangsu, Zhejiang, Fujian, Guangdong, Guangxi, and Hainan provinces and the authorities issued a circular calling for offshore wind power to declare parts of the concession tender, and offshore wind power concession tender exercise was launched in April.

Jiangsu, Zhejiang Bohai Bay region compared to large wind power density (more than 200W/m2), while no strong typhoon, for large-scale offshore wind farm construction is expected to become large-scale offshore wind farm construction in recent years. Jiangsu Province plans to build 10 million kilowatts by 2020, wind farms, including offshore wind farm seven million kilowatts, while the overall planning in Zhejiang Province is 100 million kilowatts. According to reports, now we have basically decided to select two in Jiangsu coastal wind generators offshore wind power project and two beach projects, offshore wind power development of a single item scale of 300 thousand kilowatts, tidal flats developed 200,000 kilowatts of wind power, Energy Bureau to prepare this 1 million kilowatts of four projects at the same time for bidding. Shi Lishan, “said Shanghai’s Donghai Bridge Offshore Wind Farm has been fully installed, there are already more than 10 units in operation. The construction of offshore wind projects have accumulated significant experience, but also strengthened our speed up the development and utilization of offshore wind energy resources determination and confidence. ”

It is worth mentioning that in the spring and summer 2010, will have two important events in China and Norway in offshore wind power cooperation. Norway’s Consul General to Mr Impey said: “I applaud China’s determination to develop new energy sources. I hope that this commitment will help to promote the great potential of offshore wind power development. As the overseas co-parties, the Kingdom of Norway in Guangzhou Consulate General, Innovation Norway, the Department will be opened in the active site of its rich Norway Special Orientation offshore wind power technology. and set the national pavilion during the exhibition period, the Norwegian wind power companies will showcase their cutting-edge technology and products.

In the wind’s blowing, the wind mini generators wheel rotation, so that the air force can be transformed into mechanical energy (speed + torque). Wind wheel hub shaft fixed to the generator, wind generator drive wheel rotational axis of rotation, drive to issue permanent magnet three-phase three-phase AC generator. Changing wind speed, suddenly big suddenly small, given the current and voltage wind  power  generator also with the change. Electricity sent through the controller rectifier, the AC into DC with a certain voltage to the battery charging. DC output from the battery through the inverters, turned to 220 volts AC, supply the user’s home appliances.

Recently held in Jilin Wind Power Work Forum National Grid came an important signal: the full implementation of the national grid to be strict on wind power online access. The National Grid has proposed building the wind farm, wind power network, all aspects of business operation and management standards, are pushing them into the national standard. Energy officials also expressed the access threshold set wind power, wind forecast management and rational “abandoning the wind” of public approval.

The main wind power generators by the local Development and Reform Commission officials, provinces, major wind energy business group leader and the major wind power equipment factory executives participating in the meeting, the national power grid to deliver the industry’s intention to strengthen the management of urgent Wind Power mentality. The National Grid standard to the national standards, no doubt will bring the domestic wind power equipment industry reshuffle effect, a number of technical capacity is not enough vendors will be eliminated.

Response to the national grid, “and net hard,” Interrogation

Since last year, with the large-scale wind turbine generators installed capacity launched, “wind power is difficult,” “a large number of wind turbine idling” and call for enacting. National Grid has so hamstrung by the industry, is alleged to lazy to fulfill the law of “full protection of the acquisition,” obligation, hindered the development of wind power industry.

State Grid Corporation of India deputy general manager of Shu Biao at the national forum on wind power grid for the first time a comprehensive response to these industry Interrogation: First, there is no planning, consumptive orientation is not clear, wind generators development and construction of power grids between the lack of coordination, can not do organic interface; second wind power project with the approval of the project out of line, state and local approval, respectively, the first batch of wind generators project, power project after the grant; Third, the construction period does not match.

Wind power generators industry in Guangdong Yang Ming Group undertaken by China National Industry Promotion and Improvement Project –2.5/3.0 ultra-compact type (SCD) wind turbine on the 29th in Guangdong Zhongshan off the assembly line marks the level of China’s equipment manufacturing wind power turbines in the world area occupied by the new commanding heights of China’s high-power fan speed up the localization of equipment manufacturing industry and autonomy, promote the development of offshore wind power industry is important.
SCD Fan Yang from the Ming and German wind power company Aerodyn shore-based and sea-specific characteristics of wind power, after three years of joint research and development designed to integrate the advantages of international and domestic fans, the drive chain from the main bearings, 2 planetary gear and the permanent magnet synchronous generator, whose weight than traditional 1.5MW doubly-fed machine lighter, more compact, smaller, more efficient, fully reflects the advanced technology and product economy. The first wind turbine offline SCD Taiwan, Yang Ming wind generator means that products will form a 1.5-3MW full range of products.
Yang Ming is China’s wind power industry group engaged in large-scale megawatt-class wind turbines and other renewable energy equipment, one of the five main manufacturers, the company last year, production value 5,000,000,000 yuan, to deliver wind turbine produced 630,000 kilowatts. Up to now delivered a cumulative total of about 1.2 million kilowatts fan. Companies adhere to independent innovation in the development of the MW-class fans in technology leadership. Has formed a 1.53MW series annual output of 500 MW capacity of machine produced more than 80% of large parts of domestic industry matching chain.
Ming Yang, chairman of small wind turbines industry, said Zhang Chuan Wei, Ming Yang will design a new generation of international advanced level of SCD product as the core, high-capacity fan development direction and strategy for the development of positioning, is committed to developing multi-MW offshore wind turbines. The formation of the next three years, international development and utilization of wind power total solution provider status.
In the offline ceremony, Ming Yang upgrading of the structure of wind power around the product and business model innovation, with a number of agencies and units of the signing of a cooperation agreement.

China’s rapid development of onshore wind power has made the world’s startling, today officially launched the tender offshore wind power, it immediately triggered a major wind farm developers, “Happy Valley Circle Sea” enthusiasm. Coastal provinces and cities have introduced wind power development plan, generous start planning construction of offshore wind power project. But the industry view, the offshore wind power generators is like a “premature infant”, in the absence of well-developed case available on the rush, many are hidden risks of haste, less speed.
First, wind energy resources. Bureau of Meteorology in China early this year to complete the first detailed investigation and evaluation of wind energy resources, and publish the initial results, our measured 25 meters water depth of 5 meters to the line within the coastal area, 50 meters high above sea level may be about 200 million kilowatts installed capacity . In this survey before, the industry has been that offshore small wind turbines  resources in China up to 750 million kilowatts.
Of course, the detailed planning offshore wind power have not had time to develop. A report on wind power studies pointed out that there are too optimistic to expect that the region’s offshore wind energy resources. In fact many coastal areas of China’s wind energy resource development value has yet to be demonstrated, and some places will be developed by 2020, offshore wind power development target for the amount of wind resources in technology development of all.
In addition, with similar land-based wind power development, technical constraints from the start one of the factors of wind power development. The NDRC energy in renewable energy development Ren Dongming, Deputy Director of the Centre’s view, although China has made to achieve a MW of fans, and has its own technology, but if large-scale development of offshore wind power, China 3 MW or greater capacity fan technology and there is still a gap between foreign countries, and now Europe has achieved the production of 5 megawatts or more fans. A U.S. wind power experts said the United States, the development of offshore wind generators technology is still in research stage, in the land of wind power is not fully developed before any large-scale development of offshore wind power.
And technology is closely related to the price, it relates to offshore wind power generation cost. Offshore wind farm into the intertidal zone and in deep waters. Relatively land-based wind farms, offshore wind farms are the main problems facing the high cost, complex environment, requires high reliability, sea power (600,627, stock it) forces supporting measures. It is understood that domestic land-based wind power project cost an average of 8,000 yuan / kW, of which wind power equipment cost about 5,000 yuan / kW, while the cost of offshore wind power at 20,000 yuan / kW or so, is more than twice the land-based wind power.
High cost means higher electricity prices need to be able to ensure the developer benefits. After years of land-based wind power development has been greatly reduced price, last year, authorities developed a land-based wind power feed-in tariff. Offshore wind power priced? Now, land-based wind power will continue after the way the tender price. While taking into account the wind turbine generators purchase cost, offshore wind power requires government subsidies to give more. Land-based wind power per unit subsidy of about 0.25-0.3 yuan subsidy per kWh of wind power at sea and up to 0.6-0.7 yuan. These subsidies will eventually need all the people “pay the bill.”
Of course, the special layout of our industry, developed coastal provinces, industry, power consumption, while China’s onshore wind energy resources are mainly in the west, far from the centers, long-distance power transmission grid construction progress by the constraints of offshore wind power is close to the load centers to develop offshore wind power wind power development in China inevitable trend, and even our country needs offshore wind far better than other countries.
However, haste makes waste. Chinese Academy of Engineering Ni also believes that the foundation of offshore wind power in addition to high cost of land-based turbine generators is twice that, technically there are many issues – such as monitoring difficult, expensive and large parts of offshore operations, corrosive and other difficult to handle. In his view, the offshore wind power can do some demonstrations, but not to a time when large-scale promotion. “Unless the image of engineering.” Ni said.

May 20, China Aviation Industry Corporation (AVIC) Wai Tak Engineering Co., Ltd. 2.0 MW of wind power generators doubly-fed variable pitch wind turbine offline success in Baoding.

Gai Xingji group number of technical lead at home. This type of wind generators uses the latest design of the generator in Europe, and the drive system matches the high, also the first time the use of a super-elastic sleeve such as the latest technology.
