Problems solved by technology

[0005] (1) It uses water to test the air tightness of the exhaust manifold. After the leak detection is completed, there must be residual moisture on the exhaust manifold. The exhaust manifold with residual moisture is not conducive to subsequent work. If the residual moisture is dried Drying will make the whole detection process complicated, and the way of drying water is not only inefficient and slow, but also leads to extremely high humidity in the detection work space, reducing the service life of nearby electronic equipment
[0006] (2) The airtightness test of the exhaust manifold is not only to detect whether there is a problem at the moment, but many problematic exhaust manifolds have defects and hidden dangers in the early stage of production. It is difficult to find the airtightness problem only through high-pressure compression testing Hidden dangers
