Pneumatic technology, like electronic technology and hydraulic technology, has become one of the effective technologies for automating the production process and plays an increasing role in the construction of the national economy. In many industrial sectors, microelectronics and pneumatic technology combined with the level of application is regarded as an important indicator to evaluate the degree of automation and modernization of the industry. In foreign countries, pneumatic is called “cheap automation technology”. According to statistics, in developed industrial countries, all automated processes in about 30% of the pneumatic system. 90% of the packaging machine, 70% of the casting and welding equipment, 50% of the automatic operator, 40% of the forging equipment and laundry equipment, 30% of the coal mining machinery, 20% of the textile machinery, footwear, wood processing, food machinery, 43% of the industrial robots have pneumatic systems. The United States, Japan, Germany and other countries of the average annual growth in sales of pneumatic components 10% to 15%, many industrialized countries, the output value of pneumatic components has been close to the output value of hydraulic components, and is still developing at a greater rate.
Pneumatic technology is widely used in various fields of industrial production, can realize the workpiece pickup, suction lifting, handling, positioning, clamping, assembly, cleaning, cleaning, cooling, testing and so on.
1、Production automation: machining production line parts processing and assembly, workpiece pickup, suction lifting, processing parts handling, transposition, positioning, clamping, feeding, loading and unloading assembly, cleaning, testing and other processes, robots. In packaging automation such as fertilizers, chemicals, food, food, pharmaceuticals, bioengineering, etc. to achieve automatic metering and packaging of powder, granular, lumpy materials, used in the tobacco industry, automated cigarette rolling and automated packaging and many other processes, for viscous liquids (such as paint, ink, cosmetics, toothpaste, etc.) and toxic gases (such as gas, etc.) of the automatic metering and filling. Currently pneumatic control devices in automation occupies a very important position.
2、electronic semiconductor home appliance manufacturing industry, such as the handling of silicon wafers, components of the insertion of people and tin soldering, color TV, refrigerator assembly line.
3、Transportation and automobile manufacturing industry: brake brake of train, packaging and loading and unloading of goods, warehouse management and opening and closing of vehicle doors and windows in the transportation industry;automobile manufacturing industry, including welding production lines, fixtures, robots, conveyor equipment, assembly lines, painting and spraying lines, engines, tire production equipment and other aspects.
4、light industry, electrical control and pneumatic control devices are roughly equal. Pneumatic control in China has been widely used in textile machinery, paper and leather and other light industry, such as automatic air jet looms, printing machinery, shoe machinery, plastic production lines, artificial leather production lines, glass products processing line and many other occasions.
5、Pneumatic technology is also widely used in the aviation industry. Because of the electronic devices in the absence of cooling devices is difficult to work in the 300 ~ 500 ℃ high temperature conditions, so the modern aircraft using a large number of pneumatic devices. Meanwhile, pneumatic devices are also widely used in rockets and missiles.
6、Most of the automatic devices of torpedoes are pneumatic, because with compressed air as the power energy, they are small and light, even smaller and lighter than batteries with the same energy.
7、Others: unloading of gates in factories in the construction, steel, mining and chemical industries, operation of valves in chemical systems, air separation and vacuum lifting of bookbills, driving and feeding of medical dental drills and logging machines, metallurgical machinery, construction machinery, agricultural machinery, and so on.
