Constant temperature vacuum low-pressure test chamber, simulated high-altitude low-pressure test chamber, vacuum testing machine

Description :

　　1Constant temperature vacuum low-pressure test chamberTechnical principle:

　　1. Require the vacuum chamber to be a completely sealed container, circular or square;

　　2. Vacuum pumping principle: Connect a tube from a completely sealed vacuum chamber, pass it through a manual valve or solenoid, and then connect it to the vacuum pump's pumping port; When the required vacuum level is reached, stop the vacuum pump and close the manual valve or solenoid valve to maintain a certain vacuum level inside the box; Simultaneously install a vacuum gauge to display the vacuum level;

　　3. After starting the vacuum pump, the vacuum pump compresses the air in the completely sealed container, making the pressure inside the box lower than the ambient pressure. Through the exhaust port, it is discharged into the environment, and all the air inside the box is extracted to achieve the vacuum effect; The lower the negative pressure, the higher the vacuum degree;

　　When the air inside the box is completely restored, activate the inflation function to fill the box with ambient air at the same pressure as the environment, which means complete restoration;

　　5. Use this cycle for vacuum testing.

　　2、 Overview

Simulated high-altitude low-pressure experimental chamberAlso known as high-altitude low-pressure simulation test box, vacuum simulation test box, designed for UL, EN, IEC and other standard requirements, it can achieve the low-pressure storage state of the sample in a short time, automatically control the test cycle, monitor the pressure changes inside the box throughout the process, and achieve automatic termination of the test.
