It is well known that China's national machinery industry started from a very low base. Especially after the end of the First World War,
A large number of machinery and equipment from abroad into the Chinese market, so that the development of China's machinery industry is very slow, the production of machinery and equipment is not fast.1925 "five thirty" tragedy, Shanghai set off a wave of strikes, advocating for the national products of the call for the day stronger. In 1925, the Jiangzhe area of successive years of drought, the support of Bingyuan and other people founded the new engineering company, began to copy the centrifugal pumping machine, double cylinder, double row pumping machine, water filtering tanks and other types of drainage and irrigation equipment, in order to alleviate the urgent needs of the disaster victims. 1926, the Nanyang University in Shanghai, held an industrial exhibition. The third venue, for the German businessman Tianli foreign banks and Danish businessman Rosende foreign banks display of diesel engines, pumping machines, electric motors and so on. Zhi Bingyuan dared to compete with this showdown, in the Tianli foreign firms before the display, set up a homemade 8-inch caliber centrifugal pumping machine, at the same time driving pumping, for comparison. As a result, the new product is light and solid, the price is particularly low, compared with imported products. Make the country people very excited, think national products can compete with foreign goods is very much a raise eyebrow. During this period, the national industry in the foreign businessmen and bureaucratic capital of the double dumping crowded under the difficult situation, support Bing Yuan to overcome all the difficulties, with perseverance and not afraid of failure, leading the design of imitation varieties of internal combustion engine: 3 horsepower kerosene engine, 6 horsepower, 8 horsepower (punch lamp single cylinder), 10 horsepower (single cylinder marine), 15 horsepower (single cylinder), 16 horsepower (punch lamp double cylinder), 20 horsepower (double cylinder), 30 horsepower (double cylinder). ), 30 HP (twin-cylinder), 36 HP (twin-cylinder), 45 HP (twin-cylinder), 54 HP (triple-cylinder), 75, 90, 100 HP diesel engines are used as lighting and small power supply in power plants, and they are supplied to the Anting and Xiaoshan Yong'an Electric Lighting Company, Shengxian Kaiming Electric Lighting Company, and Jiading Nanxiang Electric Lighting Company .......
The installed capacity of the engines reached more than 200 kilowatts, accounting for about 30% of the total installed capacity of the engines sold by the Shanghai National Machinery Industry for use in power plants.
Then, Zhi Bingyuan and keen to see: practical Diesel (Diesel) diesel engine was made in 1897, the thermal efficiency of this diesel engine is higher than other internal combustion engines. But initially it is a large volume, for fixed operations. the early 20th century Diesel diesel engine applications are becoming increasingly widespread, 20 years on the Chinese market Diesel diesel engine are foreign products. Zhi Bingyuan is not willing to be at the mercy of others, aspiring to fill the gaps in the country in 1929, copied into a 36-horsepower two-cylinder Diesel diesel engine, the opening of China to manufacture this diesel engine of the first.
Initiatives and Achievements in Railway and Bridge Engineering
From World War I onwards, no railroads were built in Guannai, China (except for the three eastern provinces) for a long time. At that time, the construction of railroads were also stopped halfway, the railroad construction team had to be re-established. 1933, Zhejiang Province, sponsored by the Hangjiang Railway started, Zhi Bingyuan y feel that this move for the revitalization of the nation's big plan. Driven by this strong sense of responsibility, as well as the need for the development of the new company, he dared to gnaw on the "hard core" - resolutely contracted the Jinhua River and Quzhou East Trace River two bridges of steel beams, steel beams *** counting 25 holes, each hole is 20 meters long, especially the Jinhua River, 12 holes, some of which are in the middle of the bridge, and some of which are in the middle of the bridge. 12 holes, some in deep water, some in shallow water, some on the beach, erection of beams is very difficult. Zhi Bingyuan good organization and play lifting workers experience, in the absence of practical skills and advanced lifting equipment, after many thorough investigation, highlighting a clever word, research in the 20-meter-long bearing beams laying rails, loaded with flat cars to send the entire steel beams on the abutment. Because he is good at work in the exploration, continuous improvement, the initial placement of a hole takes 10 days, and finally reduced to 3 days. No water in the river in winter, Zhi Bingyuan make full use of this advantageous conditions, break the rule, will be 13 holes on the bearing beams all transported to the middle of the river on the beach assembly riveted together, with a single bar hanging on the abutment, a great success. Success in the first battle, so that the support of Bingyuan confidence, build the bridge more vigor.
The following year, he led a team of skilled craftsmen to camp in the mountains, contracted by the Zhejiang-Ganzhou Railway, Yu South section (from Zhejiang Jiangshan through Jiangxi Yushan to Nanchang) Xinhe, Lingxi, Shaxi three bridges of the entire project. The upper steel girder installation and erection project of Xinhe Bridge is a steel plate girder with a span of 20 meters． *** 10 holes. Support Bingyuan research using new means of transport; the full length of 40 meters of the load beam. Carrying beam system with a steel profile composed of square rails, beforehand in the bridge head assembled into a whole after pushing to the bridge deck, because the length of the bridge can be across 2 holes, so it can be pushed forward and not fall through. Carrier beams in the two bridge platforms located in the above laying rails, the bridge can be pushed to the installation position. Then by lifting tools will bridge top high, let load bridge flat car exit and remove the rail sleeper, will carry beams pushed forward, so that the bridge slowly fall in the abutment position. This method has changed in the riverbed or on board the sleeper frame, the bridge up on the bridge deck of the traditional craft, so that the bridge and the river water conditions from the relationship, not affected by the weather, both time-saving, but also saving, and safety, is the first domestic, can also be regarded as the later development of the formation of the bridge bridge bridge and the principle of the prototype.
Guangdong-Han Railway, Zhu Shao section of the Zhanghe Bridge steel girder erection construction methods, is another major innovation in the history of bridge engineering support Bingyuan. Zhanghe Bridge is located in Hunan-Guangdong border, in southeast Hunan Yizhang County. Bridge pier height of 40 meters, from a distance like a chimney, usually the riverbed is dry, because the train passes from the mid-levels, so the bridge pier to be high. Zhi Bingyuan offer 10,000 yuan, the road bureau is extremely surprised, because their budget for the bridge is 100,000 yuan. Ling Hongxun, director of the Bureau of this ask Zhi Bingyuan, Zhi told to their own construction program, and said that this method can still be profitable, the results make Ling Hongxun greatly appreciated. Zhangshu bridge **** 3 holes, each end of a 20-meter steel plate beam, the middle of a 30-meter truss beam. Zhi Bingyuan set the way, the middle of the square frame beams in the river under the rocky beach assembly, in the abutment on the left and right installation of two pairs of double-pole beams (A-word handle), the steel beams in two pieces from the bottom of the river suspended on the abutment. Climbing rope bolted to the top cap of the bridge abutment, ready to complete the installation mission in Yuehan Road, 40 meters of the installation of the bridge tool cut off, installed in the middle of the bridge hole as a bearing beam. According to this plan, if you do not count the loss of bridge tools, installation costs less than 5,000 yuan.
But in line with the scientific attitude of excellence, Zhi Bingyuan and engineers Qian Yiyu according to the past experience of using the bar at the ends of the bridge to lift the steel beams, has gradually formed a fishing way to extradite the steel beams from the air without the idea of bearing beams underneath. Construction, because the piers are high, the use of four-speed hoist speed is slow, from the steel beams off the ground to lead on the piers of the entire lifting process, it will take 13 hours. So, Zhi Bingyuan decided to implement a new conception of the airborne plan, and make a test. Will have been transported to the bridge head of the 40-meter bridge tool as a steel beam, from the opposite abutment on the tie on the bar, simulated dragged out of the bridge, leading to the opposite abutment. The test showed that it was very smooth, and then dragged it back to the original place, and the result was a successful air crossing. Later, the Guangdong-Han Railway Nanping section of the steel plate beam erection, basically according to this method, are ahead of schedule, the Road Board is very satisfied. Steel beams in the air across the abutment of the new method of bridge erection, after the bridge industry in China widely spread.
Ganjiang River Bridge for the support of Bingyuan carefully built bridges in the largest project. Its girder construction process using the floating method. The floating method of bridge installation was used in the Qiantang River Bridge project, which started in 1935. The bridge was designed by Mao Yisheng and built by a foreign contractor. Zhi Bingyuan built Ganjiang River Bridge using the floating method of girder erection, is in the Qiantang River Bridge construction, and to develop and become. Qiantang River floating tool for the bottom flat and the surface is also flat square boat two, with four jacks at the corners of the steel beam at the same time to raise the method of raising the steel beam. Zhi Bing Yuan is used two ends of the 6-meter high up the flat-bottomed boat, following the principle of submarine, the water into the cabin, the use of drainage hull elevation method will be lifted up the steel beams, its efficiency and speed are more than the Qiantang River bridge project of the floating method. Ganjiang bridge steel girder floating, the beginning of two tugboats also used to tow the square boat, because of the danger of wind, changed to install a winch on the tugboat, positioning the anchor to connect the square boat with a steel wire rope, slowly hauling in place. This is a branch of the Bingyuan has always been good at the local conditions, another example of ingenuity.
Lead the development of China's first diesel automobile engine and gas automobile engine
June 1931, Shenyang Minsheng factory to make some of its own parts, the use of some imported key components, made a truck. In addition, there were only attempts to assemble automobiles using imported engines and chassis in China in the early 1930s. Engine is the key part of the car, the initial car engine is mostly gasoline engine, the late 20s appeared high-speed diesel car engine (speed more than 1,000 revolutions per minute). Since diesel fuel is cheaper than gasoline, it is more economical to use diesel cars than gasoline cars. In the process of manufacturing diesel engines, Zhi Bingyuan generated the idea of trial production of diesel automobile engines, he had many times in front of the foreign car stopped to contemplate, stay and forget. Because of the difficulty of manufacturing this engine, high cost, technical uncertainty, in the general view of the loss is not worth it. But Zhi Bingyuan is determined to create a technical achievement, and even in the trial production process even the idea of failure has not had, see how confident. About 1935, the branch Bing Yuan bought a British Commer brand truck, in their own original research on the basis of the commissioned engineers Lu Jingyun presided over the imitation of the Perkins brand engine. Perkins brand engine for the Diesel high-speed diesel engine, the power of 35 horsepower, the rated speed of 2,200 rpm. At that time, its speed is very high, the domestic has not been tried. Zhi Bingyuan, Lu Jingyun get the relevant information only a manual, which only has a number of external photos and simple instructions. In support of the careful organization of Bingyuan and Wei Ru, Lu Jingyun and others after a simple trial observation, the engine will be dismantled, step by step analysis, and by the Zhi Shaomei, Min Genrong and other mapping. According to the engine structure is compact, complex and other characteristics, Lu Jingyun conceptualized various technical solutions. In terms of construction principle, basically according to the prototype mapping; in terms of materials, had to choose their own material type; in terms of processing technology must also be redesigned. According to the reference book, Lu Jingyun learned the world's high-speed diesel automobile engine crankshaft, connecting rod, piston and other parts of the material type, as well as the cylinder material requirements.
In the cylinder block, cylinder head and other castings, in order to be able to obtain the best metallurgical organization under the conditions of Shanghai at that time, Zhi Bingyuan imported iron and nickel alloy particles from abroad through an agent, so that it is melted into the ferric water containing silicon containing low carbon, which is easy to promote the formation of pearlitic, improve the microstructure and properties of cast iron, smelting of cast iron with low nickel alloy, and after inspection and analysis of the metallurgical organization (fine pearlitic) and strength meet the requirements, thus casting a complex structure, accurate size of the cylinder block, cylinder head.
In addition to castings, most of the engine parts are steel parts. At that time, the vast majority of steel used in the general domestic machine shop for ordinary carbon steel, no experience with alloy steel. According to the relevant reference materials, according to the different performance requirements of the parts, the support of Bingyuan to the foreign banks to buy the necessary alloy steel. In order to improve the machining accuracy, Zhi Bingyuan and others took two measures: one is in the drawings with the size of the tolerance; the second is each part of the development of separate machining process, this advanced practice at the time of China's machine shop is not common.
The crankshaft is an important part of the engine, Xinzhong can not be forged because there is no suitable forging equipment. Zhi Bingyuan and others in no choice but to use the larger size of the square low-nickel alloy steel saw into a billet, and then cut with a machine tool to form the square steel saw under the remnants of the cutting made of connecting rods. He also bought some accessories in the Shanghai market, such as German-made high-pressure oil pump injector nozzle, British-made camshaft drive chain and tensioning device, as well as piston rings, fan belts and so on. By 1936 most of the parts had been completed, and in the spring of 1937 the engine assembly was completed, which was China's first homemade high-speed diesel automobile engine. It was installed in the Commer brand truck, driven by Zhi Bingyuan himself to the city government public utility bureau to report the success of the test drive. Later, the Commer truck with the homemade engine played a role in the transportation within Shanghai when the new middle school was moved to the city.
"August 13th" the day after the Shanghai war, Lu Jingyun decided to support Bingyuan long vacation, from the army against the mouth. Zhi Bingyuan responded positively to the Resource Committee and other departments of the organization of the internal relocation, led the staff of Xinzhong through the hardships, will be thousands of tons of equipment moved to Wuhan. After the emergency in Wuhan, Xinzhong moved to Changsha and Qiyang. Changsha is less than 1,000 miles away from Wuhan, and there is no danger to defend, if Wuhan is lost, Changsha will become a front-line city, from the perspective of the war in Changsha factory does not seem to be necessary, and even extremely unwise. The fundamental purpose of setting up a branch factory in Changsha is to realize the long-cherished dream of manufacturing larger horsepower automobile engines. He could not forget about the manufacturing of technically complex internal combustion engines. Changsha Huangtuling new manufacturing branch of the new company started in 1938, support Bingyuan will be invited Lu Jingyun back to the factory to preside over the trial production of engines. Because of the war tensions, Du Yuming initially forbade Lu to leave. After a personal visit to Xiangtan to explain his reasons, Du was able to authorize Lu to return to Xinzhong in support of his patriotism.
With the help of officials from the Ministry of Economic Affairs, Du's 200th Division gave a German truck to Chip Ping-yuan that had been scrapped and was no longer operational. Its engine for the M. A. N brand Diesel high-speed diesel engine, power 65 horsepower, rated speed of 1800 rpm. Branch Bingyuan decided to copy this engine, in the absence of any relevant information on the case of organization mapping. Lu Jingyun to the factory, the branch Bingyuan Li Peijin, Chu Yinglu, Lahuakun and other technical personnel concentrated in Changsha, a full-scale imitation of the M. A. N engine than the Perkins engine volume, structure is simpler, Lu Jingyun and others feel that the trial is more certain. So Zhi Bingyuan decided to set up a batch production line despite the serious threat of bombing by enemy planes.
The wartime metallurgical industry in the rear is still backward, the supply of steel is far less convenient than Shanghai, the conditions are very difficult. Zhi Bingyuan running around, inquiring about supply channels, and finally thought to buy from the railway department was damaged by the Japanese aircraft bombing of the locomotive scrap as raw materials. At that time, it was estimated that the locomotive main axle is a good steel (may be alloy steel), it is used to make the crankshaft, with the hoop system of connecting rods, with the rail system of general steel parts. There was no larger forging equipment and suitable grinding machine, the crankshaft was made by first forging the axle off, then cutting and shaping it on the machine tool, and finally finishing and grinding it. In the process of self-refining cast iron, can not find imported iron-nickel alloy particles, nickel coins as an additive, and cast iron, scrap steel with the melting in the furnace, the refining of low-nickel alloy cast iron. Due to the support of Bingyuan, Lu Jingyun and others have pre-war experience, the new in the smooth casting of the cylinder block, cylinder head, with the waste aircraft parts cast into a piston. In addition, such as oil pumps, nozzles and flywheel forging billets, by Zhi Bingyuan went to Hong Kong to buy. Due to the Yuehan Railway transportation has been abnormal, he personally escorted, from Hong Kong with private boats to Guangxi Qinzhou, Fangcheng area ashore, and then manpower by hundreds of miles to Nanning, and then long-distance transportation by road to the plant, Changsha fire, the new factory moved to Qiyang, the route is very twisted. 1943 in November, the Chinese Society of Engineers held in Guilin during the Society, quite a lot of members traveled all the way to Qiyang to visit the new company, the new company, the Chongqing National Government Minister of Economy Weng Weng. Weng Wenhao, Minister of Economy of Chongqing National Government at that time, also came to inspect the company. See Xinzhong company with the same industry and the Bank of China to jointly run the people's livelihood ironworks, steelmaking plant, because of the steelmaking furnace needs charcoal bar and Guangxi Chemical Plant and jointly run the Chinese carbon plant, but also because of the increasing demand for coal and the joint venture to form a joint venture with the Qiliqiao Coal Mining Company, but also to the Jianxiang Flour Mills to invest in the Xinzhong power, supplying neighboring factories, Risin Battery Factory and Jianxing equipment factory, so that the Qiyang Xiaoyi as if it had become a base of industry, is a very valuable miracle of the resistance period of self-sufficiency. This is a very valuable miracle of self-sufficiency during the war. Weng was very happy, and appreciated Zhi Bingyuan's patriotism, strong entrepreneurial spirit and outstanding talent.
Trial production of the M.A.N engine began in Changsha in the summer of 1938 and was transferred to Qiyang in the fall. By 1939, parts processing was completed and assembly began. In June of the same year, 65 horsepower diesel car engine in the new Qiyang factory made, installed in the original has been repaired on the old car, the trial was successful.
In the summer of 1939, it was more difficult to go to Hong Kong to buy accessories. After the outbreak of the Pacific War, the supply of German accessories and raw materials was interrupted, and Xinzhong was unable to mass produce diesel engines. In addition, wartime diesel fuel became a very tight strategic materials, diesel engines due to the lack of oil and almost out of service. Zhi Bingyuan examined the situation, taking into account the rear production of coal, in the M. A. N engine replica before the success of the work to start it into a gas engine. This is mainly to change the oil pump into a high-voltage coil and distributor, add cold spark plugs (imported), gas intake pipe, gas control valve, equipped with a gas furnace, the history of the change in the cylinder bore, liner, 'cylinder head, valves, compression ratio, pistons and so on. There are also certain changes in materials, such as pistons from aluminum alloy into a low nickel alloy cast iron, flywheel from forgings into castings. In order to build diesel engines easily in the future, most of the parts of the gas engine and the M.A.N. diesel engine could be used together. 1939, after June 1939, Xinzhong began to test the production of the gas engine, and it was successfully tested in the beginning of the following year. The gas engine had a power of 45 horsepower and a rated speed of 1,500 rpm, which could be matched with a generator. With a goal of producing 30 gas engines per month, Jibingyuan initially produced 3 engines per month, but later reached 6 engines per month. This engine was popular in the rear and was used to generate electricity or drive small ships. Zhi Bingyuan ordered it and the gas generator to be mounted on a truck, and in 1942 he and his driver drove the car from Qiyang, through the rugged mountains of Hunan, Guangxi and Guizhou, and successfully arrived in Chongqing, creating the history of the domestic gas engine-driven car, which was an important event in China's modern mechanical history. At that time, Chongqing "Ta Kung Pao" published an article will support Bing Yuan as "China's Ford". 1943 support Bing Yuan designed and test production success of a domestic automobile has been driven in Hunan Lijiaping to Qiyang between the Japanese invasion of Qiyang and the destruction of the present only to retain the photographs.
In the winter of 1943, the Chinese Society of Engineers decided to honor Zhi Bingyuan with a gold medal in Guilin in recognition of his pioneering achievements in the manufacture of internal combustion engines. He became the fifth person after Hou Debang, Ling Hongxun, Mao Yisheng and Sun Yueqi to receive this highest honor in Chinese engineering and technology.
Scientific and technological achievements before and after the establishment of the People's Republic of China
After the victory in the War of Resistance Against Japanese Aggression, China's industry was in a state of disarray. Zhi Bingyuan returned from the United States to study, as general manager and chief engineer of the China Agricultural Machinery Corporation. Based on the strong desire to revitalize the national industry, and according to the concept of the United Nations Relief Committee, he formulated a major provinces and cities in China to establish 18 branch factories in the counties set up 3,000 iron store of the ambitious plan. But later because of the intentions of the United States consultants and angrily resigned from the post of general manager, and changed to become a subsidiary of the company's Wusong Manufacturing Plant (now Shanghai Diesel Engine Factory) Director, this plan also went down the drain. Although suffered this major setback, support Bingyuan realize "industrial salvation" of the long-cherished will remain unchanged. Under his leadership in the design, the plant in March 1948, the first batch of trial manufacture of gasoline engines, the original design of 5 horsepower, the actual 5.5 horsepower, so that 5 and a half horsepower gasoline engine, that year, the production of 50 units, with it and the Second World War, "relief supplies", the United States manufactured pumps supporting the power of agricultural irrigation and drainage machinery. In the same year, the factory also basically completed the annual output of 3,000 sets of 5 ? horsepower gasoline engine required for the process equipment. The people's government trust Zhi Bingyuan, transferred to the East China Ministry of Industry as director of machinery, leading the organization of various machinery factory assets, re-assignment of tasks, to resume production. 1950 May, the central government decided to invest 3.75 million kilograms of millet (equivalent to 60.75 million yuan) to build the first new China's heavy machinery factories, designed by the Chinese engineers and technicians themselves. This is a major initiative in China's industrial history, has stirred the Shanghai intellectual community and attracted international attention. Zhi Bingyuan immediately responded to the prestige of his intellectual circles in Shanghai, and went out of his way to go door to door, passionate publicity and mobilization. In his generous speech and meticulous persuasion, some experts and celebrities quickly eliminated the **** Producers still hold the attitude of hope, some of the Taiyuan sandy winds and poor living conditions, and there are on the ability to build such a large heavy machinery plant lack of confidence and other concerns, have been put into the design team, but also hired to 56 technical staff and more than 30 skilled workers. Zhi Bingyuan was appointed as deputy director of the preparatory office of the Central Ministry of Heavy Industry Heavy Machinery Plant (later deputy director and chief engineer of Taiyuan Heavy Machinery Plant) and director of Taiyuan Engineering Office, director of Shanghai Office. Under his presidency, there are more than 40 well-known engineers and university professors from various enterprises in Shanghai, such as Zhi Shaoyan, Yang Tingbao, Luo Shiyu, etc., with a high sense of responsibility for the development of the motherland's industrial construction, utilizing the time outside of their posts, giving full play to their enthusiasm and creativity, overcoming many difficulties, and completing the planning documents in only 40 days. Zhi Bingyuan spiritedly playing the Shanghai office presented "only my pioneer" banner, led a team of investigation, to Taiyuan, Shanxi, Yuji, Taigu and other places to investigate the terrain, selected site. 1950 October 4, the second anniversary of the founding of the country's salute in the aftermath of the sound of the Taiyuan Heavy Machinery Factory officially broke on the construction of the construction of the joyful sound of firecrackers. Joyful sound of firecrackers. Its high-speed construction and put into production, cohesion of Zhi Bingyuan and other experts of the high degree of wisdom and hard work and sweat, for China's independent construction of large-scale enterprises to break out a new way. In 1954, Zhi Bingyuan was transferred to Shenyang Mining Machinery Factory as deputy director and chief engineer. This "big man" is so approachable - he usually eat and live in the plant, often in his spare time to understand the situation in the workshop to study the problem. For mining machinery, he fell in love with, far-sightedly delineated a blueprint for the development of Shen Mining Plant. Digested, transformed a number of Soviet technology, increased the plant's main product varieties. Among them, there are many technically demanding new products, such as drum filters, dust mixers, spiral classifiers and plate feeders, etc., under the leadership of the design of the support of Bingyuan came out one after another. There are also many products have created China's first occupied product records, such as φ2800 × 60,000 cylinder mixer, bandwidth of 650 mm electric unloader, bandwidth of 650 mm electric sand funneling machine, CKP11-type chain scraper transporter, the diameter of 2,000 mm disc feeder, FW - 24-type flotation concentrator, BK BGN--15, BGN--24 type peripheral drive thickener, pistonless Baum type coal washer, etc. The belt belt-type sand filter with a width of 1,000 mm has a capacity of 1,000 tons. Among them, the successful trial production of belt magnetic separator with a bandwidth of 1,000 millimeters provides new advanced technical equipment for metal beneficiation in China. There is also the successful trial production of China's first mast crane, 1955 was selected to Leipzig Industrial Exhibition, won the international acclaim. This many new products, and ZhiBingYuan training and training out of a design, development of mineral processing equipment, engineering and technology team together with the icing on the cake, so that the Shen mine plant is full of vitality, for the development of the national economic program has made due contribution.
It is worth mentioning that, in 1954, China's machinery industry began to engage in standardization, the support of Bingyuan immediately set up a standardization section of the Shen Mining Plant, and repeatedly elaborated on its importance, so that a number of comrades actively involved in this work. Under his leadership only took four years to engage in more than seven hundred standards, the earliest in China's machinery industry to develop unified technical standards. He was also one of the founders of the Shenyang Mechanical Society.
Chi Bingyuan 65 years old, transferred to Beijing, the former First Ministry of Machinery Industry, lifting and transportation machinery research institute deputy director and chief engineer. In order to reduce the labor intensity of workers, improve the level of mechanization of handling operations, he carefully studied and analyzed the development of foreign science and technology, and tirelessly climbed the mountains and mines, inspecting factories, stations, ports and terminals, with technicians and workers presented up to discuss the problem, the research program, to solve the technical problems, and contributed to the development of China's lifting and transporting machinery and new technologies, new products. In addition, he did not pay attention to the economic benefits of scientific research work, showed early concern, and advocated the implementation of research topics paid contract system.
In 1966, Zhi Bingyuan suffered from heart disease, gallstones and other diseases, after two major operations, with disabilities. In accordance with the wishes of the branch Bingyuan, Mrs. Huang Jingqing and children, his salary savings of 50,000 yuan, to the Chinese Mechanical Engineering Society.
