Pneumatic products can be divided into several categories of control elements, detection elements, gas source treatment elements, vacuum components, driving elements and auxiliary components. Control element is an element that controls the start and stop of the driver, such as solenoid valve, manual valve, etc.; Detection elements are vacuum pressure and flow components, such as pressure sensors, vacuum sensors, flow sensors Elements such as water such as water, oil, garbage, etc. or components that regulate pressure; vacuum components generate air compression of air compression or absorb other products. Affiliated components used together, vacuum elements, etc.
Pneumatic power machinery and component products are the key development areas of the hydraulic and pneumatic sealing industry. Data research shows that the proportion of 19.9% is 19.9%. As a result, the total industrial output value of my country’s air pressure power machinery and components is 28.62 billion yuan. According to the data disclosed by the Shanghai Liquid Qiqi Industry Association, the total industrial output value of the 26 -in -air industry’s key contact enterprises was 16.53 billion yuan, an increase from last year. Statistics of China’s pneumatic product output show that the output of my country’s pneumatic products is declining the month of the month. The total output of my country’s pneumatic products is 445.82 million. Later, due to the impact of the epidemic, the total output of pneumatic products fell to 4209 million, a year -on -year decrease of 6%.
According to statistics from the Chinese Machinery Industry Yearbook, my country’s pneumatic products can be divided into pneumatic tools, pneumatic systems and pneumatic auxiliary assess. The statistical yearbook statistics of the output of subdivided products, of which the output of pneumatic tools is high, 437356 units
Although my country’s aerodynamic industry has reached a certain scale and technical level, compared with the international advanced level, there is a large gap. The output value of my country’s pneumatic products accounts for only 1.3% of the world’s total output value, only 1/21 of the United States, 1/15 in Japan, and 1/8 of Germany. This is very disproportionate to the great power of more than 1 billion people. From the perspective of varieties, there are 6500 varieties in a Japanese company, and only 1/5 of it in my country. The gap between product performance and quality level is also very large.
Pneumatic technology focuses on the development direction of miniaturization, miniaturization, modularity, low power consumption, integration, intelligence, standardization, and extending service life of pneumatic products. In the future, low -carbonization (pneumatic energy saving), integration of electromechanical (combination of gas drive and electric driver), and systematic (that is, plug -in) will also become the focus of product development. At the same time, as China promotes the upgrading of the manufacturing industry and vigorously develops intelligent manufacturing, the development, production and popularization of robots in the future will drive the rapid development of air pressure components. Based on the compound growth rate of 5%, it is expected that the industrial output value of the air pressure power machinery and component products is expected The scale reached 38.4 billion yuan.
Hangzhou has recently updated the “2022-2026 Pneumatic Component Market Research Report”. The future development trend of the component industry has made scientific predictions.
As pneumatic technology is increasingly applied to automatic assembly and automatic processing small pieces and special items in various industries, the performance of the original traditional pneumatic elements is continuously improved. At the same time The variety of pneumatic components is increasing, and its development trends are mainly in the following aspects:
The size is smaller, the weight is lighter, and the power consumption is lower. In the manufacturing industry of electronic components, drugs, because the volume of the processing parts is small, the size of the pneumatic element is bound to be limited. Development direction. Ultra -small solenoid valves have been developed abroad with only the size of the thumb and an effective cross -sectional area of 0.2mm2. It is more ideal to develop components with small shapes and large flows. To this end, the traffic has increased by 2 ~ 3.3 times. There is a series of small solenoid valves. Its valve body width is only 10mm, and the effective area can reach 5mm2; 15mm width and 10mm2 in the effective area.
Many use occasions of pneumatic components, such as steel rolling machines, textile assembly lines, etc., cannot be interrupted due to the quality problems of pneumatic components during working hours, otherwise it will cause huge losses. Therefore, the reliability of pneumatic components is very important. On sailing ships, there are many pneumatic components, but there are not many pneumatic component factories that can enter this field. The reason is that its reliability requirements for pneumatic components are particularly high, and it must pass the certification of international machinery.
Development direction of pneumatic components: higher security and reliability. The international standards of pneumatic technology can be seen that the standards not only put forward interchangeability requirements, but also emphasize security. The pressure of resistance tests such as pipe joints and gas source treatment shells is increased to 4 to 5 times the pressure of use, and the pressure resistance time is increased to 5-15 minutes. If these international standards are implemented, the domestic air cylinder tube（pneumatic cylinder barrel）, Pneumatic Cylinder Kit, gas source treatment casting and tube joints will be difficult to meet the standard requirements. In addition to the resistance of the pressure resistance, some regulations have also been made in the structure. For example, the external regulations of the transparent shell treated with gas source should be added with a metal protective cover.
