Two technical projects of Suzhou Metrology Institute passed the acceptance of Jiangsu Provincial Market Supervision Bureau

[ Instrument Network Instrument Development ] On September 3rd and 4th, the former Jiangsu Provincial Quality Supervision Bureau scientific and technological project “Study on the calibration method of medium and high pressure gas micro flow meter” and “Commercial air purifier and fresh air system testing” undertaken by Suzhou Metrology and Testing Institute The method study "successfully passed the acceptance of the Jiangsu Provincial Market Supervision Bureau.

The leaders of the provincial bureau and the municipal bureau attached great importance to the acceptance meeting of the project. Wei Huaiqin, researcher of the Provincial Bureau of Science and Technology, and Zhang Ying, director of the Municipal Bureau, Xing Dongsheng, deputy director of the Municipal Bureau, and Director of the Department of Science and Technology, Yin Xiang, and Deputy Director of Jing Jingjing A special trip came to the meeting.

At the acceptance meeting of the “Study on the Calibration Method of Medium and High Pressure Gas Micro Flow Meters”, five experts from Southeast University, China Metrology University, Jiangsu Institute of Metrology and other units listened to reports, access materials, field inspections, on-site questions, etc. The method details the development of the project. The expert group fully affirmed the work done by the project team and the results achieved. It believed that the project was based on the plunger-type cavity intercommunication structure established by the constant pressure variable volume method, and realized the working pressure and flow by using the branch pressure balance control technology. Accurate control has reached the domestic advanced level. The acceptance experts agreed that the medium and high pressure gas micro flow standard device developed by the project has a wide flow range, high precision level and wide applicable pressure source, which can meet the calibration requirements of different types of micro gas flow meters, fill the domestic gap and enhance the The hospital's flow calibration capability has a good market and application prospects.

At the “Commercial Air Purifier and Fresh Air System Testing Method Research” project acceptance meeting, an expert group consisting of five experts from Nanjing University, Nanjing University of Technology, Changzhou Inspection and Testing Standards Certification Institute and other units made the project team The work and achievements have been fully affirmed. It is agreed that the unified mathematical model of the fresh air purification facilities proposed by the project solves the problem of purification performance evaluation under different working modes of external circulation and internal circulation; the designed and expanded modular test cabin can meet the requirements. The requirements for the detection of commercial air purifiers and fresh air systems; proposed and verified the scientific and reasonable detection methods of commercial air purifiers and fresh air systems, providing strong technical support for industrial development, and the technical level has reached domestic leading.

The expert group recommended to continue to increase the promotion and application, further provide technical services and professional guidance for production enterprises and research institutions, and strive for higher economic and social benefits.
