Overview of fuel foam resistance and foam detection method
The foam property is a conditional value of the foam volume after the oil is inflated under specified conditions. Air release value is expressed in the oil precipitation capacity values, the conditions of air bubble in oil characteristics and air release value change, influence of the surface activity of fire-resistant oil, fuel oil resistance of the surface activity, can be attributed to the degree of pollution and degradation of fire-resistant oil, to find and eliminate contamination, inhibit the growth of a bubble, replacement of high-performance high-volume adsorption filter core is the top priority.
SH126B liquid crystal foam tester (Shandong Shengtai instrument Co., LTD.) according to GB/ T12259-90 "lubricating oil foam performance measurement method" and ASTMD892 design, measurement of engine lubricating oil, gear oil, hydraulic oil and other oil foam characteristics, in order to assess the foam tendency and foam stability degree of lubricating oil. The instrument dynamic temperature control, automatic timing, air source and gas flow centralized control, using 32-bit ARM processor control, high-definition color touch screen display, PID temperature control and setting technology has the advantages of accurate temperature testing, high constant temperature accuracy. The instrument can be operated according to GB/T12579-90 "Lubricating oil foam Performance Determination method" test method. Used for testing the resistance of oil, lubricating oil, gear oil, hydraulic oil and other oil products.
