The vacuum industry leads the trend introduction

According to the data, China started its vacuum industry in the 1950s and 1960s, and entered the rapid development period after the 1990s. In the past 20 years, the application of vacuum technology has expanded rapidly. At present, its application fields are all over the national economy, such as aerospace. Aviation, nuclear industry, metallurgy and smelting, auto parts vacuum heat treatment, electrical industry, electronic information industry, production of semiconductor integrated circuit main equipment, paper industry, environmental protection industry, food and pharmaceutical industry, etc., and become high-tech industry development The industry that provides important equipment, for which the performance, quality and technical level of vacuum products directly affect the various sectors of the national economy, the inspection and leading of product quality in the vacuum industry becomes necessary.
 
The National Vacuum Equipment Quality Supervision and Inspection Center was established in 1987 by the Shenyang Institute of Vacuum Technology, the only national research institute in the vacuum industry. It was established due to the development of the vacuum industry. The Center was approved by the China National Accreditation Service for Conformity Assessment in 1998. The third-party inspection and testing institution authorized by the China National Certification and Accreditation Administration Committee undertakes the supervision and inspection of the product quality of the industry. It has undertaken the national vacuum equipment quality supervision and inspection tasks, the arbitration investigation commissioned by many courts, and the inspection of new products. It has made important contributions to the technological progress of the vacuum industry and the improvement of product quality.

China's vacuum industry products are mainly divided into three categories: 1. Vacuum equipment: all kinds of vacuum pumps mainly include rotary vane vacuum pump, slide valve vacuum pump, Roots vacuum pump, steam flow vacuum pump, water ring vacuum pump, dry pump, molecular pump, etc.; Application equipment: vacuum coating equipment, various vacuum furnaces, etc.; 3. Vacuum gauges and vacuum fittings: all kinds of vacuum valves and vacuum gauges.
 
There are about 500 production enterprises in the vacuum industry. The geographical distribution in China is mainly in five major regions, Liaoning (including Beijing), Jiangsu and Zhejiang (including Shanghai), Guangdong, Shandong, and western (including Chengdu and Lanzhou).
 
In the past ten years, the overall level of the vacuum industry has been greatly improved. The production of vacuum products has matured from design level to processing and performance. The quality of products produced by major enterprises has been relatively stable, and the appearance quality has been significantly improved, such as vacuum block. The technical indicators of plate valves, vacuum butterfly valves and vacuum diaphragm valves are close to or reach the international advanced level. In the past, the long-standing problem of fuel injection and gas leakage has been controlled in recent years, and the material properties of the valve have been improved.
 
The vacuum industry provides basic equipment for all walks of life. Its application fields are extensive and expanding, such as aerospace, nuclear industry, metallurgy and smelting, electrical and electronic information semiconductors, papermaking, environmental protection industries, etc. The direct relationship between performance, quality and technical level affects the various industries of the national economy, especially the ability of high-tech technical equipment. Therefore, the quality supervision and management of the vacuum industry is strengthened, and the inspection and testing services are provided to the industry through the National Vacuum Equipment Quality Supervision and Inspection Center. The channel, master the quality of the industry products, provide reliable technical support for the formulation of industry standards, provide authoritative product quality data and analytical countermeasures for government departments, provide technical quality basic information and development recommendations for the industry, and better guide enterprise products. Upgrade and quality improvement make the vacuum industry develop healthily.
 
The technical standard is the soul of product design and manufacture. It promotes and standardizes the improvement of product performance through standard improvement and innovation. In the standard revision, it is necessary to involve environmental protection, energy saving and emission reduction indicators and indicators targeting foreign advanced products to improve domestic products. The grades guarantee the economic interests of users, guide enterprises to adopt advanced standards, promote technological innovation and technological transformation of production enterprises, eliminate backwardness, promote industrial technology development, and improve product quality and market competitiveness.
