According to the (Tenth Five-Year Plan for Power Industry Research Report),
During this period, China will build a large-capacity thermal power unit with a scale of 560 million kW.
The scheme of high parameter and large capacity unit was presented. In these high-parameter, large-capacity units, high-end bearing technology is required as the basis for breaking.
However, there is still a large gap between China's bearing products and foreign countries. High-end bearings rely on foreign technology on a large scale.
For nuclear power plants, in accordance with the National Medium and Long-Term Development Plan for Nuclear Power, by 2020, China ’s nuclear power capacity will increase to
40 million kW, the state will invest 400 billion yuan to build 32 million kilowatt nuclear power plants. Whether it is
The second-generation, second-generation processing technology of the stream, and the third-generation technology of the AP1000, which is being introduced, are still breaking through the high-temperature air cooling.
The four generations of reactor technology, the main nuclear building as the "heart" of nuclear power plants, is the last major installation of nuclear power technology that is the most difficult.
Equipment. At present, the core technology of nuclear main pump bearings is completely monopolized by the United States, France, and Russia. Three generations of AP1000 are compressed by the main pump and hydrogen
New equipment such as aircraft are large-scale and new energy equipment that China has invested in key forces since the beginning of the 21st century.
There are products put into use, and in general, China and foreign countries are basically at the same level, but key core components, such as the main pump
The "joint" bearing completely relies on the technology of Westinghouse Company in the United States. Although the bearing had some problems during the test in the United States,
Eventually, all the foreign countries resolved it, and China still had a blank in this regard. Nitrogen compressor bearings use products from RENK,
The bearing has not been done abroad, and the negotiations have gone through bumps and turns, and ultimately only products are provided without detailed drawings and technology. Zhizhu
Once the pump bearing technology is mature, it will play a role in China's national defense construction (such as ship driving) and economic construction (such as power generation).
Slightly. Therefore, this kind of new and extremely high-tech bearings is a great challenge for our country, and it also has huge challenges.
Opportunities must be studied. In terms of nuclear power, although the domestic use of the latest EPR three generation nuclear power technology has developed the world's most
Large, single-speed nuclear power half-speed generator with a capacity of 1750MW, and the first unit was built in Taishan, China, but its power generation
The rotor support bearing adopts ALSTOM technology. It has no independent intellectual property rights and can only be processed according to drawings.
Tile generator sets, steam turbine or generator bearings and shafting often have high tile temperature or excessive vibration of the shafting, and must be stopped
Overhaul, the daily direct economic loss is more than 3 million yuan, so we must pay attention to the research of high reliability bearings.
We are a professional cixi good bearings manufacturers and china small ball bearings factory.
