Blisters may appear in the casting process of automobile wheels, and it is easy to have gaps in the process of pressing and riveting, which is difficult to distinguish with the naked eye. If the air tightness test is not performed, the performance of the car's hub will not guarantee driving safety. Therefore, the airtightness of the hub is an important indicator to measure the performance of the hub. Therefore, the airtightness detection is of great significance for the exercise of the vehicle.
The airtightness tester can be used to test the airtightness of the hub. This is a airtightness tester that uses a pressure drop method and uses compressed air as a test medium.

As shown in the figure below, the airtightness detector is applied to the hub airtightness inspection site.
