Energy equipment needs to break the bearing

Energy equipment needs to break the bearing

“The basic theory, industrial structure, brand effect, and leading high-end products are important symbols of our dream of bearing power.” Zhou Yu, secretary general of the China Bearing Industry Association, said at the 2014 Shanghai International Bearing Summit recently held.

Mr. Niu Hui, Deputy Secretary General of the China Bearing Industry Association, told this reporter that “Bearings are the key components in the energy equipment manufacturing industry and are widely used in large-scale wind power, hydropower, nuclear power units, deep drilling rigs, and offshore drilling platforms. Great equipment performance, level, quality and reliability."

According to report, in recent years, the size of China's bearing market has been continuously expanding, but China's high-end bearing products mainly depend on imports, which restricts the development of China's energy equipment. At present, domestic bearing companies are striving to achieve high-end bearing product industry upgrades, and will gradually change the long-term reliance on imports of key bearings required in China's energy equipment sector.

Gradually break through the weakness of energy equipment bearings In recent years, domestic wind power, hydropower, nuclear power, deep drilling rigs, offshore drilling platforms and other fields have opened up huge equipment demand markets, but bearings as key basic accessories have become its weakness.

In an interview with this reporter, the relevant person in charge of the Wazhou Group disclosed that: “The wind turbine generator supporting bearing is one of the core components of the wind turbine. The wind turbine bearing that is one of the key components of the high-power wind turbine over 1.5MW depends on long-term dependence. Imports have severely restricted the rapid development of the wind turbine industry. In addition, in the field of hydropower generating units, thermal power units, and oil and gas equipment, the long-term technical blockade of the foreign bearing industry has also restricted the development of such energy equipment."

Analysts pointed out that issues such as low autonomous production capacity, high-end dependence on imports, and hollow technology have become problems that China's bearing industry needs to solve urgently. If such problems are not solved for a long time, it will greatly increase the difficulty of research and production and production of energy equipment related products in China and affect the development of the energy equipment industry.

It is not easy to break the long-term monopoly in foreign countries, but the domestic bearing enterprises are facing difficulties and continue to break through the difficulties.

Relevant personage of Hunan Zonta Technology Co., Ltd. told the reporter that the first nuclear pump bearing developed by the company successfully completed the relevant tests in August, which marked the successful development of the first domestic main pump bearing for nuclear reactor cooling designed and developed independently. .

According to the above-mentioned person in charge of the Wazhou Group, recently, the 863 project of the Wazhou Group undertook the key project of advanced manufacturing technology in the 863 Program “Development of Large-scale Special Bearing Test Benches”. The “Bearing Test Bench for Large Wind Generators” passed the national acceptance test. China's domestic high-power fan supporting the rapid realization of a bearing on the nationalization of an important symbol; In addition, Wazhou Group also successfully developed and manufactured a large thermal power plant vertical coal mill bearings, has the Yangtze River Three Gorges, Yellow River Xiaolangdi water control project development Developed 50 years of maintenance-free bearings for submarine ship locks and achieved domestic matching; in the field of oil and gas equipment, it has developed 12,000 meters of deep drilling rig bearings, offshore drilling platform bearings and F-2000 mud pump bearings; series of development and manufacturing High-reliability maintenance-free bearings for chemical equipment. The successful development of these bearings has broken the technical blockade of the foreign bearing industry.

The key to the breaking of the bearing industry lies in the development direction of the high-end bearing industry in China. State Councilor Wang Yong pointed out that the mastering of the bearing core technology determines the development of the equipment manufacturing industry. Bearings are the foundation of the manufacturing industry. If China's manufacturing industry wants to embark on high-end, bearings must first go on high-end. .

The independent R&D and production of high-end bearings determines the height of China's manufacturing industry. However, according to the information provided by the China Bearing Industry Association to reporters, at present, there are many problems and “shortcomings” in the bearing industry in China, which are mainly manifested in weak research and development capabilities, insufficient innovation power, repeated construction, and excessive competition.

Iron Briquette Machine

Iron shavings briquetting machine is mainly used for all kinds of scrap metal, scrap iron, copper scrap, aluminum scrap, etc.), powder, granular powder, metal smelting additives, sponge iron bearing etc. Without any adhesion agent, the block (weight 2-8 kg) density can reach more than 5 t/M3, the briquettes can directly be used in furnace. Independent electrical control system, reliable operation, intuitive operation, easy maintenance.
