When the hydrogen nitrogen gas tightness testing machine works under the following conditions, it may cause the flow display value to fluctuate, or the test results are not repeatable.
1. The temperature of the inspected part is inconsistent with the room temperature. Solution: Put the inspected piece in the testing studio for a period of time to make its temperature consistent with the temperature of the testing studio.
2. The instrument and the fixture of the tested part are exposed to direct sunlight or hot and cold wind. Solution: Keep the fixtures of the instrument and the inspected workpiece away from direct sunlight and hot and cold wind to prevent changes in the gas density in the pipeline.
3. The inspected part is made of easily deformable materials such as rubber. Solution: prolong the time of the pressurization process, so that the deformation of the inspected workpiece has reached the maximum during this process.
4. The external air source fluctuates. Solution: Add an air storage tank externally.
