现役航空发动机在使用标准型滑油时,出现了高温区域滑油管路积炭、涡轮转子轴承结焦等问题,甚至由于滑油系统故障导致发动机空中停车。为解决上述问题,航空公司在航线中将发动机标准型滑油更换为高温型,有效提高了航线运营中发动机的维修性。
Existing aero-engines use standard lubricants, there have been problems such as coke deposits in the lubricating oil pipelines in the high-temperature area and coking of the turbine rotor bearings, and even the engine stops in the air due to the failure of the lubricating oil system. In order to solve the above problems, airlines replace the standard lubricating oil in the service line with high-temperature type, which effectively improves the maintainability of the engine in the service line.
