The high-low temperature resistance test of the sealing ring is to ensure its performance and reliability under different temperature environments. Sealing rings are usually used to close the gap or interface between two objects to prevent the leakage or entry of gas or liquid. Sealing rings may be deformed, aged, and hardened in high-temperature environments, while they may become brittle and brittle in low-temperature environments. These problems may have an impact on the sealing performance and service life of the sealing ring. Through high-low temperature resistance tests, the performance of sealing rings in different temperature environments can be evaluated, so as to select suitable sealing ring types and usage scenarios, while ensuring their quality and reliability.
experiment procedure
The high-low temperature test chamber is a common application in the high-low temperature resistance test of the sealing ring. The following are the test steps:
Prepare samples: According to actual needs, select the sealing enclosure samples to be tested. Make sure the sample is free of any damage or defects.
Determine the test parameters: According to the requirements of the sample and the actual use, determine the test parameters, including temperature range, heating and cooling rate, time, etc.
Install the sample: place the sample in the test box, install and fix it, and pay attention to the appropriate gap between the samples to avoid affecting the test results.
Start the test: According to the determined test parameters, start the high-low Temperature Test Chamber, and perform operations such as heating, constant temperature, and cooling according to the preset program.
Observation and recording: During the test, it is necessary to observe and record the temperature change inside the Test Chamber and the condition of the sample at all times, such as whether there is deformation, cracking, etc.
Analysis results: After the test, take out the sample, analyze and evaluate according to the observed and recorded results, and judge whether the sealing enclosure can meet the requirements. If further improvement or optimization is required, it can be adjusted according to the test results.
NBCHAO reminds you: When conducting high-low temperature tests, you must pay attention to safety to avoid fires, explosions and other accidents caused by excessively high or low temperatures. At the same time, the operation and maintenance of the Test Chamber is also very important, and it needs to be carried out in accordance with the operation manual and regulations.
