Description

Technical field [0001] The present invention relates to the field of testing equipment, more precisely, it relates to an automatic determination device and method for determining the characteristics of lubricating oil foam. Background [0002] The foam characteristics of lubricating oil refer to the tendency of oil to generate foam and the stability of foam. When the lubricating oil is in contact with the air during the flow and is violently agitated, it is possible to mix the air into the oil and create a foam. The foam in the lubricating oil will destroy the lubricating oil film, increase wear, reduce the cooling effect, produce air resistance in the pipeline, insufficient lubricating oil supply, oil spills in the fuel tank and other hazards. Therefore, the lubricating oil is required to have good foam resistance to ensure that the lubricating oil works properly in the lubrication system. Foam resistance is an important quality indicator of lubricating oil. The existing testing...
