Fully automatic acid value testerIt is an analytical instrument for determining the acid value of oil products. According to the GB/T7304 test method, the amount of alkali used to titrate the sample to the endpoint in the solvent is calculated as KOH, with the unit of mg/g. The significance of measuring the acid value of oil products in production operation is significant, mainly reflected in:

Based on the acid value, the amount of acidic substances contained in the oil can be determined.

2. Due to the influence of oxygen, temperature, and other conditions during operation, oil gradually oxidizes and generates a series of oxidation products, among which the most harmful are acidic substances, mainly cyclic acids, hydroxy acids, etc. The higher the acid value of the oil during operation, the deeper the degree of oil aging. Therefore, acid value is one of the main control indicators for the degree of oil aging during operation.

3. Insulating oil contains various acidic substances, which can improve the conductivity of the oil and reduce its insulation performance. When the low molecular acid content increases and there is water in the oil, it can lower the insulation level of electrical equipment and shorten its operating life.

4. During operation, the increase in oleic acid value of the steam turbine indicates that the oil has deeply aged. The formation of cyclic acid soaps in the oil can promote oil emulsification, damage the lubrication performance of the oil, cause wear and heat generation of the components, and affect the safe operation of the unit
