1. Machinery manufacturing industry
Machinery manufacturing includes the clamping and moving of the workpiece on the mechanical processing production line, the molding, tamping, box and so on on the casting production line, as well as in the automobile manufacture automobile automatic production line, the automobile body parts automatic handling and fixing, automatic welding and so on.
2. Electronic IC and electrical industry
For example, it is used for carrying silicon wafers, inserting and soldering components, assembling household appliances and so on.
3. Petroleum and chemical industries
Nowadays, the vast majority of the automated processes for conveying medium through pipelines are controlled by pneumatic control devices, such as petroleum refining and processing, gas processing, chemical fertilizer production, etc.
4. Light industrial food packaging industry
Light industry food packaging includes a variety of semi-automatic or automatic packaging production lines, such as: wine, oil, gas canning, various food packaging.
5. The robot
There are many kinds of robots such as assembly robots, painting robots, transport robots and wall climbing, welding robots and so on.
6. other
Such as vehicle brakes, door opening and closing devices, particulate screening, torpedo missile automatic control devices and so on. At present, various pneumatic tools are widely used, but also a component of the application of pneumatic technology.
1. Miniaturization and integration
Pneumatic components in many applications are required to be as small as possible, so miniaturization is the main trend of development.
2. Combinatorial and intelligent
The most common combination is a cylinder with a valve and a switch. In material handling, we also use a combination of hydraulic cylinder fittings, swing cylinder, pneumatic chuck and vacuum chuck, as well as a 1000 psi ball valve and a program controller.
3. High speed
The current piston speed range of the cylinder is 50 ~ 750mm/s. To increase productivity, the tempo of automation is accelerating.
4. Oil-free, tasteless and sterile
As human demands on the environment are getting higher and higher, the exhaust gas discharged by pneumatic components is not expected to pollute the environment with oil mist. Therefore, oil-free pneumatic components will be popularized. There are also special industries, such as food, beverage, pharmaceutical, electronics, etc., which require more stringent air requirements. Filters for such special requirements will be developed continuously.
5. High life, high reliability and intelligent diagnostic function
Pneumatic components are mostly used in automatic production, and the fault of components will often affect the operation of equipment, so that the production line to stop work, causing serious economic losses. Therefore, we put forward higher requirements for engineering reliability of pneumatic components.
6. Energy saving, low power consumption
Low-power pneumatic components can save energy and be better integrated with microelectronics. Solenoid valves with power consumption less than 0.5W have been developed and commercialized and can be directly controlled by computers.
7. Mechatronics
In order to accurately achieve the predetermined control objectives, we should adopt closed-circuit feedback control. In order to realize this kind of control mode, the conversion between digital signal of computer, analog signal of sensor feedback and pneumatic control air pressure or air flow should be solved.
8. Apply new technology, new process, new material
In the manufacture of pneumatic components, such technologies as profile extrusion, casting leaching and module assembly have been widely used in China. New die-casting technologies (hydraulic core-pulling, vacuum die-casting, etc.) have been gradually popularized at present. Piezoelectric technology, bus technology, new soft magnetic materials, dialysis membrane are being applied.
