Abstract

The embodiment of the invention provides a system and a method for evaluating high-temperature deposition and degradation characteristics of aviation lubricating oil. The system comprises an electric spindle, a bearing tool, a test lubricating system, an accompanying test lubricating system, a mold temperature controller, a cooling-water machine, an air compressor and an electric control cabinet, by applying the scheme provided by the embodiment of the invention, the aviation turbine engine lubricating oil is placed in the bearing tool, the test main shaft is driven by the electric main shaft to rotate to simulate high-speed operation of the aviation turbine, the pressure borne by the aviation turbine during operation is simulated through the radial loading device, and the temperature of the aviation turbine during operation is simulated through the heating ring; air pressure in the test cavity is adjusted while sealing airflow is provided through the air compressor, so that an air pressure environment for simulating operation of an aviation turbine is simulated, then comprehensive simulation of actual working conditions is achieved, high-temperature deposition and degradation characteristics of test lubricating oil can be evaluated after the test runs for a certain time, and research and development of oil products are guided.

Description

technical field [0001] The invention relates to the technical field of mechanical lubrication, in particular to a system and method for evaluating high-temperature deposition and degradation characteristics of aviation lubricating oil. Background technique [0002] With the development of aero-engines towards high temperature, high speed, and high thrust-to-weight ratio, the engine's requirements for lubricating oils continue to increase, and aero-engine lubricating oils are urgently required to have better oxidation stability and high temperature resistance. The effective, repeatable and practical evaluation method of high-temperature oxidation and coking performance of aviation lubricating oil has guiding significance for the research and development, oil selection and performance evaluation of aero-engine lubricating oil. [0003] At present, the only test method for evaluating the coking performance of aviation lubricating oil is the SH / T 0300 crankcase simulation test m...
