Tubular heat exchanger is a wall heat exchanger with the wall surface of the tube bundle enclosed in the shell as the heat transfer surface. The heat exchanger has the advantages of simple structure, low cost, wide circulation section and easy cleaning of scale. However, the heat transfer coefficient is low and the floor area is large. It can be made of various structural materials (mainly metal materials) and can be used at high temperature and high pressure, which is the most widely used type.

It is understood that the "Agricultural Machinery Navigation and Automatic Operation System" was jointly developed by Academician Luo Xiwen of the Chinese Academy of Engineering and Foton Lovol Heavy Industry. The system is based on the European and American auto navigation technology, combined with the specific conditions of domestic agricultural production, fully learns the development ideas of foreign agricultural machinery, all adopt three-dimensional technology optimization design, set global satellite positioning, GPS automatic navigation, electronically controlled hydraulic automatic steering, Automatic adjustment of work tools, automatic opening and closing of the throttle, and emergency remote turn-off and many other automation functions. The accuracy of the linear navigation and tracking is less than 5 centimeters, the accuracy of the automatic alignment is less than 10 centimeters, and the control accuracy of the steering wheel declination is less than 1 degree. The tractor automatically controls precise sowing, fertilizing, ridging, sprinkling, and other operations, greatly improving the standardization of tractor operations, thereby realizing precision agriculture.
Luo Xiwen said that this is the first time China has truly applied the agricultural navigation and operation automation system in Datian to truly realize unmanned driving, which reflects the modernization, intelligence and automation of modern agricultural machinery in China. In the future, actual production applications will continue to increase the degree of intelligence. After mass production, the price is at least 1/3 cheaper than that of the United States under the premise of guaranteeing quality and performance. At present, this agricultural machinery navigation and automatic operation system has undergone many tests and shows that the accuracy of automatic navigation is 5 centimeters, which is close to the international advanced level. It is hoped that through hard work, we can truly reach or even exceed the international advanced level.
Academician Zhou Ji of the Chinese Academy of Engineering highly praised the successful transformation of “agricultural machinery navigation and automatic operation†from theory to practice, and with the continuous development and perfection of China’s “Beidou Satellite Navigation System†network, it can significantly reduce costs and facilitate the navigation of agricultural machinery. And the promotion and application of automatic operations. Zhou Ji also fully affirmed the efforts made by Foton Lovol Heavy Industries in China's agricultural modernization, and hoped that there will be more production-study-research combined results in the future to promote the development of national agricultural modernization.
Wang Yurong, deputy general manager of Foton Lovol Heavy Industry, said that the automatic navigation system and operating system for agricultural machinery is the result of independent research and development. The application of the system truly reflects the level of intelligence and automation, which facilitates precise operations, reduces labor intensity, and enables continuous operation at night. In particular, large blocks play a significant role. “The state proposes that the enterprise is the main body of technological innovation, and that production, research and production are the leading factors. The advent and application of agricultural machinery navigation and automatic operation systems are examples of concrete results. Innovation is endless, and Foton Lovol will also intensify innovation and develop more new The products will contribute to China's agricultural modernization," said Wang Yurong.
Foton Lovol builds the country's first driverless tractor
The editor was informed that the driverless tractor equipped with "agricultural machinery navigation and automatic operation system" produced by Foton Lovol Heavy Industries, located in Fangzi District, Weifang, Shandong Province, recently performed a demonstration of cotton sowing and other demonstrations, marking the first time in China's field test. Application of agricultural machinery navigation and operation automation system truly realizes unmanned driving. After the batch production of this driverless tractor, its price is at least 1/3 cheaper than that of the United States.
