Digital display seal tester product operation method:
The vacuum chamber is evacuated by the sample immersed in water to generate external pressure, observations in the case where the sample gas to escape, in order to determine the sealing properties of the specimen; through the vacuum chamber is evacuated, the specimen is generated inside and outside The pressure difference is observed, and the shape of the sample is recovered after the sample is expanded and the vacuum is released, thereby determining the sealing performance of the sample.
Note:
Seal tester
Product model: MFY-2 (normal type)
Product use: MFY-2 seal tester is suitable for sealing test of packaging bags, bottles, tubes, cans, boxes, etc. in food, pharmaceutical, medical equipment, daily chemical, automotive, electronic components, stationery and other industries. It is also possible to test the sealing performance of the test piece after the drop and pressure test.
Features:
1. It adopts manual control to maintain pressure, which is more convenient to operate and more stable in performance.
2. All pneumatic originals are made of well-known manufacturers, and the performance is stable and reliable. The pressure holding instability caused by pneumatic originals is eliminated.
3. High-quality plexiglass (acrylic) sealed barrel, the wall thickness is increased to 15mm, which effectively enhances the compressive strength of the sealed barrel and prolongs the service life.
4. Electronic pressure holding device reduces mechanical wear and makes the holding time last longer.
5. PVC operation panel, pressure digital display, resolution to 0.1kPa, convenient for users to accurately view the pressure value.
6. Built-in time display, holding pressure start timer synchronous timing, convenient for users to record and observe the holding time, the pressure keeping end timer is automatically cleared.
Test principle:
The vacuum chamber is evacuated by the sample immersed in water to generate external pressure, observations in the case where the sample gas to escape, in order to determine the sealing properties of the specimen; through the vacuum chamber is evacuated, the specimen is generated inside and outside The pressure difference is observed, and the shape of the sample is recovered after the sample is expanded and the vacuum is released, thereby determining the sealing performance of the sample.
