| Abstract: | Since the failures such as aging, oil leak or air leak often occur in rubber seal ring in the hydraulic system during operation, a modification plan for a new material seal ring is raised in combination with a certain aircraft, so as to meet the requirements of system high temperature and dynamic sealing operation. The test results prove that new material seal ring is applicable for operation at high temperature and on the dynamic sealing places, and can be used as substitute for 5171 butadiene nitrile rubber seal ring. |
