Lubricity is the ability of a fluid to reduce friction and wear between two surfaces in relative motion. Lubricity is an important property of fuels, lubricants, and additives, as it affects the performance and durability of engines and machinery. Lubricity testing is a method of evaluating the lubricating quality of fluids under various conditions of pressure, temperature, speed, and load.
One of the most widely used lubricity testing methods is the High-Frequency Reciprocating Rig (HFRR) test, which simulates the sliding contact between a fuel injector and its bore in a diesel engine. The HFRR test measures the wear scar diameter (WSD) on a steel ball that reciprocates against a steel disk immersed in the test fluid. The WSD is an indicator of the lubricity of the fluid, as a smaller WSD means less wear and better lubricity.
The Ducom HFRR 4.2 Lubricity tester is designed for excellent compliance with test standards and minimizes the cost of ownership. HFRR 4.2 has an integrated high-precision humidity controller that is salt-free and only needs distilled water to maintain precise humidity levels without influencing the temperature of the conditioned air. The system is computer controlled and completely automated. It also has powerful and intuitive software that places all necessary controls on a single screen, allowing quick set-up of tests with minimal training.
Ducom’s cutting-edge High-Frequency Reciprocating Rig (HFRR) Lubricity Tester provide accurate and consistent measurements of the lubricity of oils and fuels, making it an invaluable tool for a wide range of industries.
The DUCOM HFRR 4.2 features a high-precision servo motor that controls the reciprocating motion of the ball holder, a digital temperature controller that maintains the test fluid at a constant temperature, and a high-resolution optical microscope that measures the WSD on the ball and disk.
The ball moves back and forth at a high frequency, creating a wear scar on the specimen. The size of the scar is then measured and used to determine the lubricity of the sample.
HFRR-4.2 is a reliable and user-friendly device for measuring the lubricity of diesel fuels. It can perform tests according to various international standards, such as ASTM, ISO, DIN and others, by selecting the desired protocol from the software menu. This reduces the need for extensive user training, minimizes errors, and lowers operational costs.
