The purpose and significance of aviation kerosene lubricity tester
The aviation kerosene lubricity tester is mainly used to evaluate the lubrication performance of aviation kerosene (jet fuel). By simulating the friction conditions of precision components in the aviation engine fuel system, standard steel balls and annular friction pairs are used to move under controlled conditions, and the size of the wear marks generated on the surface of the steel balls is measured to quantify the boundary lubrication performance of the fuel.
Testing lubricity indicators is crucial for aviation safety, as aviation kerosene is not only used as fuel in engines, but also plays a role in lubricating precision components such as fuel pumps; Insufficient lubricity can exacerbate friction and wear of metal components, which may lead to component failure or even mechanical failure. According to industry statistics, the annual consumption of aviation fuel worldwide is enormous, with engine wear caused by insufficient lubricity accounting for 12%, resulting in significant direct economic losses. This test provides key quality control basis for fuel manufacturers and testing agencies, ensuring that the fuel meets airworthiness standards and supporting additive research and formulation optimization, thereby improving engine operational stability and service life.
