Foaming Characteristics of Lubricating Oils.
This test method covers the determination of the foaming characteristics of lubricating oils at 24°C and 93.5°C. Means of empirically rating the foaming tendency and the stability of the foam are described.
Semi-automatic Apparatus for Foaming Characteristics of Lubricating Oils – 4 places
Bench top instrument with metallic case structure painted with anti-acid products and double chamber insulation, top cover made in stainless steel with four holes for the cylinders accommodation and one hole for 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 stirrer grants uniformity and stability of bath temperature.
Stainless steel grid divide the glassware from the heating and stirring device.
Air pre-heating system by copper coils immersed in the first bath.
Lateral stand-by support for stoppers and diffusing assembly.
Anti-floating and centring system for test cylinders.
Control unit include 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 trough the activation of air micro-compressors and counter (time of blowing, waiting time, flow) – audible alarm for each intervention of the operator requested.
Air flow monitoring system (flow rate) managed digitally and calibrated.
Diagnostic panel for temperature calibration, air flow, analysis parameters.
Removable back panel equipped with drain tap for easily empty and clean the baths.
Baths are thermo-insulated equipped with tempered glass window inside for easily cleaning the limestone or oils residue, second protection panel made of plastic material with optical transparency.
