Description

technical field [0001] The invention relates to the production and detection of automobile parts, in particular to an airtight detection device for a catalytic converter of automobile tail gas. Background technique [0002] In the past ten years, my country's automobile industry has developed rapidly, and the scale of production and sales has grown rapidly. While automobiles bring convenience to people's lives, they also inevitably bring about air pollution. my country's automobile exhaust emission control started late, but developed rapidly. The continuous development of the automobile industry and the increasingly stringent emission regulations have driven the broad industrial prospects of automobile exhaust catalytic converters. Air tightness is one of the important features of catalytic converters for automobile exhaust gas. Good air tightness can significantly improve the purification effect of automobile exhaust gas. Most of the air tightness testing equipment curre...
