Overview
CHENCHI MFY-01B sealing tester is suitable for the sealing test of Encasement bags, bottles, tubes, cans, boxes, etc. in the food, medical equipment, daily chemical, automotive, electronic components, stationery and other industries. It meets the new GMP certification testing requirements, 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. The LCD touch screen displays the test process, setting the pressure, setting the pressure holding time and real-time pressure and other parameters are displayed simultaneously;
3. PVC operation panel, configure start and stop physical buttons, simple and convenient operation;
4. The sealing barrel material is made of good organic Glass pipe, and the wall thickness reaches the highest 15mm Film thickness in the industry;
5. The pressure holding time, test pressure, and supplementary pressure ratio can be set in advance to achieve one-click operation during the test process;
6. Precision pneumatic components, superior sealing performance, more reliable mass;
7. The instrument is equipped with two test modes, single-point pressure mode and three-point increasing pressure mode.
8. Automatic constant pressure air replenishment according to the supplementary pressure ratio during the test, without manual operation;
9. At the end of the test, the pressure will be automatically blown back to unload, saving more operating time;
10. The pressure sensor has a built-in pressure calibrating module and supports multi-point pressure calibrating, which is convenient for three-way calibrating;
11. Multiple pressure overloads and electrical safety protection ensure the safety of instruments and operators.
12. Optional oil-free Vacuumpump, fast vacuum, no need to buy another gas source;
13. The instrument comes with an air filtrating device, which is convenient for external water discharge and cleaning impurities, effectively ensuring the safe operation of the internal components of the machine;
14. The instrument adopts a three-power independent power supply mode, with an independent power supply for the host controller, an independent power supply for the pressure receiving module, and an independent power supply for the pressure control module.
15. The instrument is equipped with a thermal micro-printer, and the test results can be directly output and printed.
16. The instrument has the functions of saving and querying test results.
17. Optional standard serial PC communication interface or network port output;
18. Optional laboratory data management system can be purchased to achieve multi-line data statistical management.
Principle
By vacuuming the vacuum chamber, the sample immersed in water to produce an internal and external pressure difference, the test sample internal gas escape outside the case, in order to determine the sealing performance of the sample; or by vacuuming the vacuum chamber, the sample to produce internal and external pressure difference, the test sample expansion and release of the vacuum after the sample shape recovery, in order to determine the sealing performance of the sample.
Applications
Food industry, equipment industry, daily chemical industry, automotive industry, electronic components industry, stationery industry
Standards
GB/T 15171、ASTM D3078
Steps
1. Set test parameters, including pressure holding time, test pressure, and supplementary pressure ratio.
2. Select the test mode (single-point pressure mode or three-point incremental pressure mode);
3. Start the test, and the instrument will automatically vacuum, maintain pressure, and replenish air;
4. Observe the sample for gas escape or shape change.
5. Automatic backblowing unloading pressure at the end of the test;
6. View and save the test results, optionally print out.
Notice
Make sure the power supply is AC 220V 50Hz to avoid voltage instability.
- Check whether the air source interface is firmly connected before use.
- Regularly clean the air filtrating device to prevent impurity blockage;
- Pay attention to the pressure range during operation to avoid overload.
- Avoid manual intervention during testing to ensure automated processes.
The instrument is powered independently by three power sources to ensure the normal operation of each module.
- When Vacuumpump is optional, no additional gas source is required.
When saving test data, pay attention to the storage space.
Adhere to relevant safety standards to prevent electrical accidents.
