What is the acid value of fuel resistant running oil and the acid value of new oil controlled?
Acid value: Due to the catalytic effect of acid components in oil on oil deterioration, it is very important to control the oleic acid value in operation. When the acid value of oil in operation is greater than 0.2mgKOH/g, the acid value of oil increases exponentially with time due to the catalytic action of acid substances, so the acid value of oil in operation is controlled to 0.15mgKOH/g. The standard control for new oil is 0.05mgKOH/g.
The acid value of resisting fuel oil is generally determined by GB/T264 petroleum product acid value determination method.
SH108 automatic oleic acid value meter in line with the People's Republic of China standard GB/T 264 "petroleum products acid value determination method" and GB7599, GB7299 stipulated requirements. The instrument adopts large blue LCD screen display, Chinese menu, no identification button. Microcomputer automatic determination, automatic printing, test process to achieve microcomputer automation, intuitive and simple operation. Magnetic stirring, no noise, safe and reliable, compact size. It can meet the needs of oil refineries, power plants and scientific research institutions. It is one of the necessary instruments for oil analysis and quality inspection.
First, performance characteristics
1. The principle of titration and neutralization method is adopted. The liquid injection, titration, stirring and determination of neutralization and titration end point are automatically completed under the control of a microcomputer. The measurement took seven minutes.
2. Special reagent bottle is used to contain the extraction liquid and neutralization liquid. The reagent is isolated from the air during use to avoid the influence of volatilization and carbon dioxide in the atmosphere. It also protects the operator.
3, automatic acid value tester can choose to test 1 ~ 3 oil samples at a time.
