Overview
CHENCHI MFY-03 sealing tester is suitable for the sealing test of Encasement bags, bottles, tubes, cans, boxes, etc. in the food, medical apparatus, daily chemical, automobile, electronic components, stationery and other industries, and can be used for the sealing performance test of the specimen after the drop and pressure test.
Features
1. Microcomputer control, test parameters can be set, and the test process is fully automated
2. Digital display setting pressure, setting pressure holding time and real-time pressure and other parameters are displayed at the same time
3. PVC operation panel, metal button operation is simple and convenient
4. The sealing barrel material is made of good organic Glass pipe, and the wall thickness reaches 15mm.
5. The pressure holding time and test pressure can be set in advance to achieve one-click operation of the test process
6. Precision pneumatic components, superior sealing performance, more reliable mass
7. Automatic constant pressure air replenishment according to the set pressure during the test, no manual intervention required
8. Automatic backblowing at the end of the test to unload the pressure, saving more operating time
9. The instrument comes with a compressed air filtrating device, which is easy to drain water and clean impurities externally, effectively ensuring the safe operation of the internal components of the machine
10. In order to ensure the normal and interference-free operation of the instrument, the instrument adopts dual power supply independent power supply: host controller independent power supply, pressure control module independent power supply
Principle
By vacuuming the vacuum chamber, the sample immersed in water to produce internal and external pressure difference, the test sample internal gas escape outside the case, in order to determine the sealing performance of the sample; by vacuuming the vacuum chamber, the sample to produce internal and external pressure difference, the test sample expansion and release of vacuum after the sample shape recovery, in order to determine the sealing performance of the sample.
Applications
Food Industry: Soft Bag Encasement, Semi-hard Encasement, Hard Encasement; Medical Apparatus Industry: Closed Container, Blister Encasement, Small Headspace Encasement; Miscellaneous: Tyvek, All Kinds of Aluminum Foil Bags, Wet Wipes, Cosmetics Encasement
Standards
GB/T 15171、ASTM D3078
Steps
1. Set test parameters (pressure, holding time)
2. Place the specimen in a vacuum chamber
3. Start the test, the instrument automatically vacuums and maintains pressure
4. Observe the change of the pressure difference between the inside and outside of the sample
5. Automatic backblowing unloading pressure at the end of the test
Notice
• The air source pressure needs to reach 0.7Mpa (the air source user provides it)
• Regularly clean the impurities and moisture in the compressed air filtrating device
• Ensure that the dual power supply of the instrument is independently powered and operates normally
• Check the sealing bucket before use. Organic Glass pipe is intact and nondestructive
• Test strictly according to the operation steps
