The invention belongs to the technical field of sealing ring service life testing, and particularly discloses a sealing ring service life testing device and method. The service life testing device comprises a simulation unit, a pressurizing unit, a connecting pipeline and a control unit, the number of the pipeline simulation units is at least one, and each pipeline simulation unit comprises a pressure cavity and a plurality of test pipelines connected to the pressure cavity; the pressurizing unit is used for applying alternating pressure; the connecting pipeline is connected with the pressurizing unit and is connected with all the pressure cavities one by one; the connecting pipeline, all the pressure cavities and all the test pipelines are internally communicated and are filled with a pressure medium; during testing, the sealing ring is installed in the testing pipeline, and the pressure medium senses alternating pressure applied by the pressurizing unit and transmits the pressure to the sealing ring; whether the corresponding sealing ring fails or not is judged by collecting the pressure of the pressure medium at the working position of the sealing ring.
Description
technical field [0001] The invention belongs to the technical field of sealing ring life testing, and more particularly, relates to a sealing ring life testing device and method. Background technique [0002] The sealing ring is an important part of the pipeline. In the large-scale equipment structure, due to the difficulty of disassembly and assembly, the difficulty of maintenance, and the high reliability requirements, it directly affects the normal operation of the entire pipeline system. [0003] For the test requirements of the sealing ring life research, usually according to the Arrhenius model, the environmental temperature of the sealing ring is increased to observe its physical properties and functional degradation; or according to the calculation of thermal gravity and activation energy, the thermal aging test is used. Test the life of the seal. However, in terms of actual use, as the internal pressure of the pipeline changes, the sealing ring will have a certain ...
