Demulsibility Characteristics of Lubricating Oils. This test method measures the ability of oil and water to separate. It is intended for use in testing medium—and high-viscosity lubricating oils.
Demulsibility apparatus, semi-automatic instrument composed by: • Bench top instrument with metallic case structure painted with anti-acid products and double chamber insulation • Stainless steel bath with double window for internal inspection, cover made in plastic material with a hole for bath thermometer and motorized stirrer. • six positions side rack for a separatory funnel for stand-by after analysis. • Temperature is controlled by Linetronic’s control board with PT100 A class, stainless steel immersion heaters, and a manually settable over-temperature protection system. • An automatic head for up-and-down movement is equipped with a turbine stirrer from 300 to 5,000 rpm, electronically regulated with digital reading and an audible beeper for the end mixing procedure. TouchTouch displays stirring time, rpm, bath temperature, and an impulsivity timer. • 6 × glassware separatory funnel included.
Semi-automatic Apparatus for Foaming Characteristics of Lubricating Oils – 4 places: • This benchtop instrument has a metallic case structure painted with anti-acid products and double chamber insulation. The top cover is made of stainless steel and has four holes for the cylinders and one hole for the control thermometer (not included). • 2 × independent 25 liters capacity stainless steel baths (one for 24°C and one for more than 93.5°C) equipped with viewing and illuminated windows, two independent motor stirrers grant uniformity and stability of bath temperature. • A stainless steel grid divides the glassware from the heating and stirring devices. • Air pre-heating system by copper coils immersed in the first bath. • Lateral stand-by support for stoppers and diffusing assembly. • Anti-floating and centering system for test cylinders. • Control unit includes 7" Touch screen panel PC with 800 × 480 resolution with dedicated Lin-Tech software able to manage the bath functions: - Independent management of 4 places analysis through the activation of air micro-compressors and counter (time of blowing, waiting time, flow)—audible alarm for each operator's intervention requested. - The airflow monitoring system (flow rate) is managed digitally and calibrated. - Diagnostic panel for temperature calibration, airflow, and analysis parameters. • A removable back panel has a drain tap for quickly emptying and cleaning the baths. • Baths are thermo-insulated and equipped with tempered glass windows inside, which allow for easy cleaning of limestone or oil residue. The second protection panel is made of plastic with optical transparency. • 4 Places Apparatus including four diffuser stones (not certified), four rubber stoppers, four air diffuser tubes, and four graduated cylinders.
