Abstract

The embodiment of the invention discloses a method for measuring the oxidation stability of oil film bearing oil. The method obtains a first thermogravimetric decomposition curve and a second thermogravimetric decomposition curve by using a thermal gravimetric analyzer, and finally determines the oxidation stability of the oil film bearing oil. In the method, no reagent such as isopropanol, n-heptane or acetone which is harmful to the body and is required by a testing-rotating oxygen and nitrogen method of the oxidization stability of lubricating oil is needed; furthermore, the testing-rotating oxygen and nitrogen method of the oxidization stability of the lubricating oil comprises multiple operation steps during testing, and experimental instruments are required to be cleaned step by step. The method disclosed by the invention is simple in process and can quickly obtain a result of the oxidation stability.

Description

technical field [0001] The invention relates to the technical field of measuring oxidation stability, in particular to a method for measuring the oxidation stability of oil film bearing oil. Background technique [0002] Oil film bearing oil products need to meet the requirements of high temperature, dusty, impact load and frequent contact with water and other harsh working conditions in the finishing mill of high-speed wire rod mills. It is also necessary to consider the extreme pressure requirements of gear transmission on oil products. Therefore, the oil film bearing oil must have excellent comprehensive properties, among which the oxidation stability of the oil film bearing oil is particularly important. [0003] The rolling speed of modern rolling mills is increasing day by day, especially the continuous rolling mills controlled by computers have high operating rates. In normal production, there are few shutdowns except for roll change. Therefore, the oil film bearing...
