Apparatus for Demulsibility Characteristics of Lubricating Oils

The primary application of the Apparatus for Demulsibility Characteristics of Lubricating Oils TT-2711 is to measure the demulsibility of medium and high-viscosity lubricating oils, in compliance with the ASTM D2711 standard. The test evaluates how effectively and quickly an oil can separate from water after being emulsified. This is a critical performance property, as good water separability is essential to prevent corrosion, oil degradation, and reduced lubrication in systems where water contamination is a risk.

Key Industries

• Lubricant Manufacturing: This is a fundamental quality control and product development test for lubricant blenders. They use it to verify the performance of their formulations—especially for turbine, hydraulic, and circulating oils—to ensure they meet the water separation characteristics required by industry specifications.
• Power Generation: This is a crucial end-user industry, particularly for steam turbine applications where water contamination from steam leaks is a constant concern. The demulsibility of the turbine oil is a critical performance parameter that is monitored to protect bearings and other components from rust and wear.
• Industrial Manufacturing (Heavy Industry): Sectors such as steel mills, paper mills, and mining operations use large circulating oil and hydraulic systems that are often exposed to water. They rely on lubricants with excellent demulsibility to allow for the easy removal of water, which is essential for protecting gears, bearings, and hydraulic components from failure.
