泄漏检测

负压法

Vacuum the sealed chamber inside the inspected product Apply helium gas on the outer surface of the product under inspection Leak detector detects changes in helium content inside the workpiece The precise location of the leak can be realized.

正压法

密封腔内充满一定压力的氦气.

当发生泄漏时, 氦气通过泄漏口泄漏到周围大气中 .

Detection of helium concentration increments in surrounding atmosphere by suction method The precise location of the leak can be realized.

背压法

Place the inspected product in a pressurized helium chamber for a certain period of time Remove the residual helium from the surface Put the inspected product into the leak detector connected with the leak detector;取一定时间内的最大泄漏率.
