Sealing rings are widely used in industry, automobile, aerospace and other fields, and require good high-low temperature resistance performance. The high-low temperature resistance test is to verify the reliability and sealing performance of the sealing ring at extreme temperatures. In high temperature environments, the sealing ring may deform, Conditioning, hardening, etc., resulting in a decrease in sealing performance, while in low temperature environments, the sealing ring may become fragile, resulting in loose seals. Through the high-low temperature resistance test, the durability and sealing performance of the sealing ring in different temperature environments can be evaluated, and high-quality sealing technology can be provided for the production of industrial, automotive, aerospace and other fields to ensure the service life of the product in various extreme environments and safety.
The low/high Temperature Test Chamber can be used to test the performance and reliability of the sealing ring in different temperature environments.

Test method
The following are the test steps of the low/high Temperature Test Chamber in the high-low temperature resistance test of the sealing ring:
Check whether the Test Chamber and temperature controller are working normally, and set the temperature range and temperature rise and fall rate of the Test Chamber according to the test requirements. Prepare the sealing ring to be tested, and pay attention to its size and material.
Install the sealing ring to be tested on the sample holder in the Test Chamber, and pay attention to its position and orientation to ensure the accuracy of the test results.
Open the Test Chamber and temperature controller, and set the temperature range and temperature rise and fall rate of the Test Chamber. Raise and lower the temperature of the Test Chamber to the set temperature range, keep it for a period of time, and then cool down to the set temperature. During the test, record the temperature change inside the Test Chamber, and pay attention to the performance change of the sealing ring.
After the test, take out the sealing ring and observe whether its appearance and function have changed or damaged. At the same time, carry out sealing performance testing and evaluation, including the sealing performance of the sealing ring, pressure resistance performance and other parameters. Through the evaluation of the test results, judge the resistance and stability of the sealing ring in the high-low temperature environment.
The sealing ring should be inspected and tested before the test to ensure its normal operation. During the test, the temperature range and temperature rise and fall rate inside the Test Chamber should be strictly controlled to ensure the accuracy and reliability of the test. At the same time, the Test Chamber should be cleaned and maintained after the test to prolong its service life.
