1946 Up to now, he is a professor in the Department of Electromechanical Engineering of Tongji University, the head of the Department of Mining Electromechanical Engineering of China University of Mining and Technology, and a second-class professor.
1959, he personally led the completion of all mechanical and electrical projects in the Great Hall of the People, which ensured the convening of the anniversary of the founding of 10. Deputy commander-in-chief of the construction headquarters of the Great Hall of the People.
1958- 1966, deputy technical director of Beijing Bureau of Mechanical and Electrical Industry, in charge of the research and development of new technologies, new processes and new products, and the industrial output value and product level have been raised to a new level. He is in charge of new product development, product quality and production technology. At the same time of his busy teaching work, he traveled to various electromechanical factories in Beijing, and successively organized and led the research and development of new technologies and new products such as new motors, single crystal refining, ultrasonic cleaning, laser drilling, hydraulic components and so on. The first hydraulic parts workshop and powder metallurgy research institute in Beijing were established, which promoted the technical level of Beijing electromechanical industry and raised the industrial output value and product grade to a new level.
As the founder of mine electromechanical specialty in China, Tang Dequan is the pioneer of fully mechanized mechanization, electrification, automation and intelligence in coal industry. As early as 1950s, he had applied modern technologies such as mechatronics and intelligence to coal industry production.
He presided over the following projects.
1. Pingdingshan No.4 Mine is a "one-stop production system automation demonstration mine", which has reduced personnel, improved safety and achieved good production effects and economic benefits.
2. The research, design, assembly and operation of the first "underground locomotive transportation signal blocking system" in China have improved the transportation speed and safety.
3. Establish the motor factory of Beijing Institute of Mining and Technology, research, design and manufacture new coal electric drills for mining, reduce weight and improve efficiency, and make contributions to the innovation and transformation of coal electric drills for mining.
4. "Research and design of new multi-rope mine hoist and its electric drive system" has created a new scheme for the transformation and innovation of mine hoist.
1965 "research and design of new multi-rope hoisting and its electric drive system in mine", a key scientific research project of the state science and technology commission, is jointly undertaken by the Ministry of coal and the Ministry of machinery, which has created a new scheme in technology. He presided over the completion of the "one-stop production system automation demonstration mine" in Pingdingshan No.4 Mine of the Ministry of Coal, which played an exemplary role.
65438-0966, responsible for the research, design, assembly and operation of the first "underground locomotive transportation signal, centralized and blocked system", a key scientific research project of the Ministry of Coal, which improved the transportation rate and safety.
During the period from 1975 to 1980, after inspecting the advanced coal mining technology and equipment in western Europe, he suggested that the Ministry of Coal introduce a batch of foreign advanced fully mechanized mining and fully mechanized excavation complete sets of equipment for testing, digestion, mapping and improvement, and develop its own domestic equipment. When the western drum shearer, drilling shearer and supporting new hydraulic support were introduced for the first time, he personally went to Pingdingshan No.10 Mine to carry out experiments and obtained various reasonable design parameters. In order to achieve the goal of localization of mechanical and electrical equipment for coal production, the Ministry of Coal approved the introduction of 8.5 million US dollars from abroad as the key detection technology and equipment necessary for the development of comprehensive mechanization. He worked tirelessly to personally lead the demonstration and review of the overall plan in his later years, and went abroad to introduce countries for consultation and selection. By 198 1 year, more than ten high-level test systems, equipment and laboratories have been established successively, such as the whole machine test of artificial coal wall shearer, the fast loading hydraulic prop test and the whole machine test of roadheader, which laid a solid technical foundation for manufacturing advanced fully mechanized mining and excavating equipment in China.
Due to the large-scale production of underground mining face, the single machine capacity of shearer reaches 600kW, which causes the problem of frequent burning of underground shearer motor. In order to solve the problem of frequent burning of underground shearer motor, he led the electrician group of Shanghai Branch to go deep into the coal mine, conducted a detailed investigation on the working condition of shearer motor, mastered the working characteristics of shearer motor overload and frequent start, and made technical research on motor structure design and insulation materials. He also personally led a team to Siemens, A.E.G and other electrical companies for technical inspection, which overcame the difficulties of high insulation materials for mining motors, improved the manufacturing technology such as vacuum dipping paint, solved the problem of frequent burning of shearer motors, and formulated the characteristics and technical standards of mining explosion-proof shearer motors, as well as a reasonable working system. The project of "motor tackling key problems of mine explosion-proof shearer" won the second prize of 1987 scientific and technological progress of the Ministry of Coal.
With the continuous increase of underground power supply capacity in coal mines, it is imperative to improve the underground power supply voltage level. He personally presided over and guided the research, design, trial production and supporting key projects of "mine thousand volt underground power supply equipment and system" jointly operated by coal and machinery. After several years of efforts, the huge and arduous power supply boosting project was successfully completed, which improved the underground power supply voltage level and solved the power supply problem of high-power and high-yield working face. From 65438 to 0989, the project won the first prize of national scientific and technological progress.
Since 1978, the key project of "Mine kV Underground Power Supply Equipment and System", which is responsible for hosting and guiding the cooperation between the Ministry of Coal and the Ministry of Machinery and Electricity, has won the first prize of the National Science and Technology Progress Award 1989.
In terms of theoretical research and personnel training, the first mine electromechanical specialty in China was established for the coal industry. Experimental research on two-phase flow theory, model similarity theory and high-pressure water jet theory has been carried out, and many graduate students have been trained. Author of mine ventilation, drainage and air compression equipment, coal mine mechanization manual and mine electromechanical paper 10.
