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.

① Based on the acidity content, the content of acidic substances in petroleum products can be determined. Generally speaking, the higher the acid value of petroleum products, the more acidic substances they contain. On the contrary, the smaller the acid value, the lower the content of acidic substances.

② The acid value can roughly determine the corrosion resistance of petroleum products to metals. The organic acid content in petroleum products is low, and it will not have a corrosive effect on metals when there is no moisture and low temperature But when its content is high and there is water present, it can corrode metals. The smaller the organic acid molecules, the stronger the corrosiveness.

③ Assess the performance of petroleum products. The acid value of diesel has a significant impact on the working condition of diesel engines. Diesel with a high acid value will increase engine carbon deposits, causing piston wear and nozzle coking. If the acidity is too high, it may be due to a high content of phenols or thiols, which not only affects the color stability of petroleum products, but also generates harmful gases after combustion that can corrode machinery and pollute the environment.

④ The degree of deterioration of lubricating oil during use can be determined based on the acid value. After a period of use, lubricating oil gradually deteriorates due to oxidation, manifested as an increase in acid value. When the acid value exceeds a certain limit, new oil should be replaced.
