AI Technical Summary
In existing aerosol generators, the delivery particle size and concentration of aerosol particles are not stable enough in leak rate detection, which affects the detection results.
An integrated aerosol generator was designed, which uses an aerosol chamber made of salt corrosion resistant material and is equipped with a liquid inlet and a liquid outlet. The gas flow rate is regulated by compressed air and a rotor flow meter to ensure that the aerosol particles have a particle size of 0.4 to 0.7 μm and a concentration range of (4 to 12) mg/m3 during the transportation process, which meets the standard requirements.
Stable delivery of aerosol particles was achieved, with particle size and concentration meeting standard requirements, thus improving the accuracy and efficiency of leak rate detection.
