The application of pneumatic components mainly includes two aspects: maintenance and matching. The expansion of the application of pneumatic technology is a sign of the development of pneumatic industry. In the past, the sales of domestic pneumatic components used to be used for maintenance. In recent years, the sales share of direct supporting parts has increased year by year. The application of domestic pneumatic components ranges from metallurgical equipment worth tens of millions of yuan to chairs worth only 1-2 hundred yuan. Specially developed domestic pneumatic components are used for railway switch, locomotive wheel/rail lubrication, train braking, street cleaning, lifting equipment in special workshops, military command vehicles, etc. This shows that pneumatic technology has "penetrated" into all walks of life and is increasingly expanding.

Although China's pneumatic industry has reached a certain scale and technical level, it still lags far behind the international advanced level. The output value of China's pneumatic products accounts for only 1.3% of the world's total output value, only 1/21 of that of the United States, 1/15 of that of Japan and 1/8 of that of Germany. This is not commensurate with a large country with a population of more than 1 billion. In terms of varieties, there are 6500 varieties in a Japanese company, only 1/5 of which in China. The gap between product performance and quality level is also large.

As pneumatic technology is increasingly applied to automatic assembly and equipment for automatic processing of small parts and special items in various industries, the performance of the original traditional pneumatic components is constantly improving, and new products have been developed to meet the market requirements, making the variety of pneumatic components increasingly increasing. Its development trend mainly includes the following aspects:

Smaller size, lighter weight and lower power consumption. In the manufacturing industries of electronic components and pharmaceuticals, the size of pneumatic components is bound to be limited due to the small size of the processed parts. Miniaturization and lightweight are the first development direction of pneumatic components. Foreign countries have developed ultra-small solenoid valves that are only the size of the thumb and have an effective sectional area of 0.2mm2. It is more ideal to develop components with small size and large flow. For this reason, the flow rate of valves with the same shape and size has increased by 2-3 times. There is a series of small solenoid valves with a valve body width of only 10mm and an effective area of up to 5mm2; Width: 15mm, effective area: 10mm2, etc.

The power consumption of foreign solenoid valves has reached 0.5W and will be further reduced to adapt to the combination with microelectronics.

Most of the air source treatment assemblies at home and abroad use block-style block structure, which is not only compact in size, but also convenient for combination and maintenance.

The positioning accuracy of the actuator is improved, the rigidity is increased, the piston rod does not rotate, and the use is more convenient. In order to improve the positioning accuracy of the cylinder, the cylinder with brake mechanism and servo system is more and more widely used. For the cylinder with servo system, the positioning accuracy of ± 0.1mm can be obtained even if the air supply pressure and the load change.

At the international exhibition, there are many cylinders with various special-section cylinder barrels and piston rods. Because the piston rod does not rotate, this kind of cylinder can maintain certain accuracy when applied to the main engine without additional guide devices. In addition, many cylinders and cylinder sliding components with various guide mechanisms have been developed, such as the cylinder with two guide rods, the cylinder with two piston rods and two cylinder barrels, etc.

The shape of cylinder barrel is no longer limited to round shape, but square shape, beige shape or other shapes. The guide groove, sensor and switch installation groove are opened on the profile, which makes it easier for users to install and use.

Multi-functionalization and compounding. In order to facilitate users and meet the needs of the market, various small pneumatic systems composed of multiple pneumatic components and equipped with control devices have been developed. For example, the components used to move small items are composed of two cylinders with guide according to X axis and Z axis respectively. The module can move 3kg heavy objects, equipped with solenoid valve and program controller, with compact structure, small occupancy space and adjustable stroke. Another example is the loading and unloading module, which has seven different functional modules. It can complete the loading and unloading operations on the precision assembly line, and can combine different modules arbitrarily according to the operation content. Another kind of manipulator is a combination of a small shape swing cylinder and a collet that can change the swing angle. There are several kinds of collets at the collet position that can be selected.

Combined with electronic technology, a large number of sensors are used, and pneumatic components are intelligent. The cylinder with switch has been widely used in China. The switch will have smaller volume and higher performance, and can be embedded in the cylinder block; Some also have two-color display, which can display the position error, making the system more reliable. Using sensors instead of flow meters and pressure gauges can automatically control the flow and pressure of compressed air, which can save energy and ensure the normal operation of the device. Pneumatic servo positioning system has entered the market. The system uses a three-position five-position pneumatic servo valve, compares the predetermined positioning target with the detection data of the position sensor, and implements negative feedback control. When the maximum speed of the cylinder reaches 2 m/s and the stroke is 300 mm, the positioning accuracy of the system is ± 0. 1mm。 Japan has successfully trial-produced a new type of intelligent solenoid valve, which is equipped with a logic circuit with sensors and is the product of the combination of pneumatic components and optoelectronic technology. It can directly accept the signal of the sensor. When the signal meets the specified conditions, it can complete the action by itself without passing through the external controller to achieve the control purpose. It has been applied to the conveyor belt of the object, which can identify the size of the object to be transported, so that large pieces can be directly sent down and small pieces can be separated.

Higher security and reliability. According to the international standards of pneumatic technology in recent years, the standards not only put forward the interchangeability requirements, but also emphasized the safety.
