The acid value tester under UHV power can help many power workers conduct various power tests more conveniently.

The fully automatic acid value analyzer for petroleum products (environmentally friendly) is a specialized instrument designed for laboratories. It has the advantages of small size, light weight, high accuracy, easy operation, environmental protection, and is suitable for use in harsh outdoor environments. The instrument adopts high-performance microprocessors and HDD new technology, which can analyze several samples simultaneously, automatically rotate the sample cup, automatically titrate the sample, automatically determine the endpoint of the sample, automatically print the test results, and avoid contact between staff and chemical reagents. This instrument is suitable for various laboratories such as military, power, and petroleum.

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.

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.
