The invention discloses a multifunctional dynamic sealing element ultra-high-speed wide-temperature-range environment frictional wear detection
system, which can simultaneously simulate multi-
physics-field coupled extreme working conditions such as ultra-high-speed rotation, wide temperature range,
oil pressure environment and axial / radial
mechanical load, and accurately reproduce actual working environments of dynamic sealing elements in high-end equipment such as aero-engines and high-speed trains. Compared with traditional equipment which only carries out single-factor or material-level testing, the consistency of testing data and practical application is remarkably improved, the problem that the deviation between
laboratory results and
engineering practice is large is effectively solved, the extreme service working condition is truly reproduced, and the
testing reliability is improved; according to the invention, three test modules are integrated, namely an end face sealing element test module, a three-valve ring sealing element test module and a circumference sealing element test module, and parts of the modules can be shared; by means of the multifunctional
integrated design, the same device can be compatible with performance evaluation of dynamic sealing pieces of different structural forms, the
utilization rate of the device is greatly improved, and the research and development cost is reduced.
