Fully automatic sealing testerstructural characteristics

It mainly consists of a specially designed transparent vacuum chamber (organic glass barrel), a vacuum generation system, a compressed air source (customer provided air source with an outlet pressure of 0.7-1.0 MPa), a pressure gauge, etc.

The main body is mainly composed of solenoid valves, vacuum conversion devices, and pressure sensors. By controlling the opening and closing of solenoid valves through PLC, the input and output of pressure can be controlled to achieve different testing processes. Simultaneously display the pressure and holding time that the container is subjected to.

Fully automatic sealing testerworking principle

By evacuating the vacuum chamber, a pressure difference is generated between the inside and outside of the test sample immersed in water, and the gas escape or water infiltration of the test sample inside the vacuum chamber is observed to determine the sealing performance of the test sample.

Working principle process: difference in gas pressure between the inside and outside of the packaging → gas expansion → gas escape → new gas equilibrium → high gas ratio inside the packaging → high gas expansion rate → high pressure on the packaging film → strong gas escape.

Note: The setting of parameters should depend on the air ratio inside the product. If the air ratio is high, the gas expansion rate inside the packaging should be high, and the vacuum pressure should be set lower at the beginning.
