GB/T 13871.4-2023 specifies the performance test procedures for swirl/spin axis lip sealing rings whose sealing elements are made of resilience materials. The standard details the preparation requirements for sealing ring samples before testing to ensure that the samples meet the test conditions. The specific operation procedures of various performance tests are clarified, such as swirl/spin speed, pressure loading, temperature control and other key parameter settings that simulate actual working conditions. Through this standard, the performance of this type of sealing ring can be accurately tested, providing a scientific basis for its mass control, Product Research & Development and application in mechanical fields, and ensuring the stable operation of the sealing system.
