Technical methods for effectively extending the service life of ozone aging test chamber Ozone aging test chamber is applied tothe aging cracking test of nonmetallic materials and rubber products.It is effectively prolong the service life of ozone aging test box and reduce the amount of maintenance will play an important role in improving the economic benefits of the test.   Technical methods for effectively extending the service life of ozone aging test chamber as follows: 1. Keep the ground around and around the chamber clean at all times. 2. It shall remove the internal impurities before operation, and clean the lab room at least once a year .  3. It not be allow the test specimen come into contact with the door seal strip when opening the door or taking the test specimen from the chamber 4.  When the end of the test, do not take out the sample at once.It must be taken out of the shutdown state  5. The refrigeration system is the core of aging test chamber,check all the brass half a year, such as leakage of the situation, the functional joints, welding mouth, if the Leakage of grease, it must be dealt with immediately 6. The condenser should be regularly maintained and kept clean.Dust sticky will make the compressor high-voltage switch trip and generate false alarm,So the condenser should be a monthly maintenance, you can use the vacuum cleaner, hard brush or high pressure air blowing dust to clean it,what attached to the condenser. 7. At the end of each test,It is recommended to clean the test chamber with clean water to keep the equipment clean;After cleaning the box, the box should be dried to keep the box dry; 8. Circuit breakers, over-temperature protection, and the operator's safety protection, please check regularly;
