The Aviation Kerosene Lubricity Tester is specifically designed to evaluate the lubricating properties of aviation fuels, particularly jet fuels. Using a standard steel ball and a standard test ring to create controlled friction, the instrument measures the size of the wear scar formed on the steel ball. This measurement provides an accurate assessment of the boundary lubrication performance of the fuel.
Operating Principle
The system is composed of two main sections: an electronic control module and a mechanical testing module. The electronic control module incorporates a microprocessor controller that provides fully automated regulation of oil bath temperature, test cycle, air humidity, and airflow. All core control units and key components are sourced from premium imported manufacturers to ensure reliability and precision.
During testing, the sample is placed in the sample chamber, where relative humidity is maintained at 10%. A test steel ball is mounted vertically in a chuck and positioned directly against an axially mounted test steel ring, with a specified load applied. The steel ring is partially immersed in the test sample and rotates at a constant speed, creating friction with the steel ball under wetted fuel conditions. After the designated test period, the wear scar diameter on the surface of the steel ball is examined under a reading microscope. This measurement is then used to determine the lubricity of the aviation kerosene sample with high accuracy.
