In his speech, Wang Fuchang said that China's bearing industry has made significant progress during the "11th Five-Year Plan" period and formed a relatively large scale of economy, making contributions to the autonomy of major technological equipment in key areas of China. China's bearing business income in the average annual increase of 18.20%, the average annual increase in bearing output of 20.11%. In 2010, the industry’s total bearing output was 15 billion sets and sales were 126 billion yuan, ranking third in the world. At the same time, Wang Fuchang believes that the promotion of the development of the bearing industry in China must promote the promotion of independent innovation capability of enterprises, speed up structural adjustment, promote enterprises to become bigger and stronger, improve product quality, strengthen brand building, improve equipment levels, accelerate technological progress, and increase service awareness. The advancement of bearings in several areas such as the autonomous application of major technical equipment in China.
Qu Xiaofei expressed in his speech that he hoped the forum would contribute more to the leap-forward development of the bearing industry in China. He hoped that the experts and scholars attending the meeting and the people in the business community would pay attention to supporting the development and construction of Wafangdian and invest in Wafangdian. Xingye achieves the goal of mutual benefit and win-win through friendly cooperation.
Qu Xianming, executive director of the Chinese Mechanical Engineering Society, Wang Yu, chief scientist of the National “973†Project, He Jiaqun, a professor-level senior engineer of the China Bearing Industry Association, and Ye Jun, chief engineer of the Luoyang Bearing Research Institute made academic reports at the forum respectively for the bearing industry. Development made constructive suggestions.
Wafangdian City, which has the reputation of “China Bearing Capitalâ€, has established a relatively complete bearing industrial system. There are more than 700 regional bearings and supporting enterprises, and 9 enterprise groups, with obvious industrial characteristics. The leading products are large and oversized. Wind turbine bearings, metallurgy mill bearings, railway wagon bearings, petroleum machinery bearings, precision machine tool bearings, mining machinery bearings, engineering machinery bearings and port machinery bearings are mainly bearings for major equipment and key units, and the products cover 9 categories. Best-selling domestic and exported to more than 80 overseas countries and regions, was included in the "China's top 50 industrial clusters." This forum will enhance the influence of the "Bearing Capital of China" city brand, attract domestic and foreign merchants to invest in Wafangdian, and build China's largest and world-renowned bearing industry manufacturing base to play a positive role in promoting.
A shell and tube heat exchanger consists of components such as a shell, heat transfer tube bundle, tube plate, baffle plate (baffle), and tube box. The shell is mostly cylindrical, with a tube bundle installed inside, and both ends of the tube bundle are fixed on the tube plate. There are two types of fluids for heat exchange: cold and hot. One flows inside the tube and is called the tube side fluid; Another type of fluid that flows outside the tube is called shell side fluid. To improve the heat transfer coefficient of the fluid outside the tube, several baffles are usually installed inside the shell. The baffle can increase the velocity of the shell side fluid, forcing the fluid to pass through the tube bundle multiple times according to the specified path, and enhancing the degree of fluid turbulence. The heat exchange tubes can be arranged in equilateral triangles or squares on the tube plate. The equilateral triangle arrangement is relatively compact, with a high degree of turbulence in the fluid outside the pipe and a large heat transfer coefficient; A square arrangement facilitates cleaning outside the pipe and is suitable for fluids that are prone to scaling.
