Influence of Gas Diffusion Head Parameters on Determination of Foam Properties in Lubricants
Foam formation is a major problem in lubrication systems as it can negatively affect system performance and increase maintenance costs.Several laboratory methods are available to determine the foam resistance of lubricants,but the choice of gas diffusion head parameters can significantly affect the test results.This study investigated the effects of maximum pore size,permeability and different materials on the measured data of lubricant foam properties.Our results show that while differences in gas diffusion heads have a small effect on test results for high quality lubricants,they have a significant effect on test results for poorer quality oils with a high propensity to foam.In addition,variations in gas diffusion head parameters can lead to large differences in test results,even if they meet the method requirements.It is therefore particularly important that the appropriate gas diffusion head parameters are selected according to the characteristics of the lubricant under test in order to obtain accurate and reliable data.
