Application
The particle leakage tester is based on reference to similar foreign equipment for independent absorption, and further improvements have been made. According to industry standards, the test device for testing the leakage rate and adhesion of the mask is redesigned and produced. It adopts salt and oil aerosol generator and photometer collection system. It adds a computer control system and improves the level of automation. It is a test device with complete functions, advanced technology and high level of automation among similar products at home and abroad.
Structure
The leakage rate test bench is domestically manufactured, but the core component photometer is imported from abroad. The air source required for the entire air circuit is external compressed air, and the power for the detection air circuit is provided by a vacuum pump. An aerosol generator and a generating pipeline are installed on the generating gas path; a pneumatic fixture with a cylinder, two photometers, and a sealed cabin are installed on the detecting gas path.
Standard
Leakage rate (EN 149-2001+A1-2009) , Leakage rate (GB 2626-2019), Tightness (GB 19083-2010)
