Chongqing is a natural gas chemical industry base with large scale, early research and development, and advanced technology. The output value of natural gas chemical industry accounts for more than 50% of the city's total industrial output value, basically forming a relatively complete natural gas chemical industry chain, and nurturing a large number of key enterprises. , key technologies and competitive products, established Changshou Natural Gas Chemical Industry Park with natural gas as raw material, Fuling Natural Gas Fertilizer Park and Wanzhou Salt Gas Chemical Industry Park. It is understood that 27 companies have been introduced into Changshu Chemical Park, which has taken shape, and the agreement has reached more than 24 billion yuan, including 3 of the top 500 companies in the world and 5 of multinational companies. The investment promotion work at the Fuling and Wanzhou bases has also achieved remarkable results. Tens of billions of projects have been planned.
In addition, major natural gas chemical projects developed by the Chongqing Chemical Research Institute, with independent intellectual property rights and good market prospects, such as natural gas catalytic partial oxidation process for synthesis gas, natural gas partial oxidation process for acetylene flexibility, and natural gas catalytic partial oxidation coupled water gas reaction system Hydrogen technologies have yet to be developed by engineering.
Drill chuck is by drilling collet, elastic dial ring, connecting piece, the back cover. In drill collet, its axial positioning is implemented using the connection piece, upon jack, via the circumference of a circle in the elastic dial ring under the action of internal thread axial movement, under the action of a precise automatic centering and clamping tool, when you are working with different drilling tools need to adopt such as center drill, drill, reamer, tap drill chuck, can loosen the positioning screw, turn the segment to the desired location, fastening positioning screw, realize the drill chuck the movement of the transfer.
The drill chuck is one of the main parts of electric tool industry and machine tool industry, widely used in electric drill, drilling machine. Chuck is connected with the tool, is used to clamp the handle type tool accessories. The drill and connection with threaded connections and taper connection in two ways. Threaded connection is mainly used on an electric hand drill, cone connection is mainly used for drilling machine drill chuck from structure can be classified as type wrench and keyless. Spanner drill chuck wrench to tighten the wheel needs, mainly used in machine tool industry, such as drill and drill. Hand drill chuck set to hold on and tighten the collet, mainly used for electric drill. Spanner drill chuck as by pulling wheel to tighten the collet and a pulling wheel is a with an extension arm of bevel gear, so in the process of screwing can serve to increase the role of input torque, so chuck clip clamping force is too large
Chongqing Chemicals' full gas production value of natural gas chemical industry accounts for more than 50% of the city's total industrial output value
At the 2005 China Chongqing Natural Gas Chemical Industry Frontier Technology Symposium, it was learned that natural gas chemical industry has become the core industry of Chongqing Chemical Industry. At present, Chongqing is relying on the Chongqing Chemical Research Institute and some large-scale chemical companies to apply for construction of natural gas chemical national engineering research centers to provide scientific support for the development of Chongqing and the west and the national natural gas chemical industry.
