Key common detection technology and standard system for pneumatic components

Release time:Feb. 27, 2018

Zhejiang easun Pneumatic Technology Co., Ltd. and Beihang University, Beijing Institute of Technology, national pneumatic products quality supervision and inspection center, pneumatic technology research institute and other companies jointly developed the "pneumatic components of key common detection technology and standard system" project, won the two prize of the 2017 National Science and technology progress award.

As one of the three major industrial power system pneumatic system, automation and process control equipment widely used in various manufacturing industries, its components are basic parts of foundation engineering in China, is the key parts of high speed rail vibration, supporting servo valve and other high-end manned aircraft oxygen equipment. However, due to the lack of testing methods and standards, China's air industry has not been able to form a uniform and effective test of product consumption and airtightness. The key common detection technology and standard system of pneumatic components solves the common problems of these industries.

The project for the pneumatic technology, the standard system of common element detection system was established to carry out innovative research, pneumatic components, general products, standard methods constitute a complete standard system, formulated or revised 30 national standards and industry standards, solve the problem of the detection and control of pneumatic element flow dynamic characteristics of leakage point precision positioning, and the result is applied in testing equipment and enterprise promotion, greatly improving the pneumatic components inspection level and manufacturing quality, enhance our right to speak in this field.

At present, the project creates pneumatic components and system energy efficiency testing method and energy saving technology system has been adopted by Chinese fly, Jin Ning, alumina MOVEVER Dicastal hub of more than 200 national enterprises, nearly three years of China's electricity accumulated more than 2 billion 800 million degrees. Not only that, the project is also applied to the fuel injection system of the long march rocket, which realizes the accurate control of the high frequency variable gas distribution.

In the course of this project, Zhejiang billion on research and development projects as the only R & D and production of pneumatic components factory, made a great contribution to research on dynamic evaluation method and the national standard for energy efficiency of component gas work, puts forward the design scheme of cylinder, vacuum generator, air tightness detection system, also developed a large caliber flow characteristics test device, pneumatic components, multi parameter measurement system, electromagnetic valve performance testing device of pneumatic components testing equipment, greatly enhance the pneumatic product testing level and efficiency.
