Problems solved by technology

The traditional "wet method" air tightness detection has defects, such as low precision, long detection time, and the inability to realize automation; the direct pressure method has low precision when measuring high pressure or the volume of the tested part is large, and has strict requirements on the external temperature , not suitable for the factory environment; the differential pressure method has complex structure, cumbersome operation, and high price; and the nitrogen detection method is too expensive

In automatic assembly equipment, it is often used to test the specific size of the product and its own air tightness. Due to the poor measurement accuracy caused by manual work, the measurement is difficult and the work efficiency is low. At present, there is no one with high measurement accuracy. Air tightness testing equipment with simple operation and high working efficiency
