Description

Technical Field

[0001] The utility model relates to the technical field of petrochemical detection, in particular to an automatic jet fuel total acid value tester. Background Art

[0002] In petrochemical testing, the total acid value of jet fuel needs to be measured. The lower the acid value, the lower the corrosion performance and will not clog the fuel system. The higher the acid value, the easier it is to form carbon deposits, causing coking of pistons and nozzles, affecting fuel economy. Safety and environmental friendliness are of paramount importance. Usually, it is necessary to titrate the sample with a known titration solvent under specified conditions. When the sample color reaches the required color after 15 seconds, the titration is stopped. After calculation, the obtained value is the total acid value.

[0003] Currently, the test instruments used to determine the total acid value of jet fuel are mostly manual. Existing automatic instruments are generally limited to magnetic stirring of the sample. Titration reagent measurement and color judgment are still mostly determined manually. This is not only labor-intensive but also prone to harm to operators due to reagent toxicity. The subsequent test process is still relatively complicated.

[0004] Therefore, in order to solve the problem that the test instruments used in the above-mentioned total acid value determination of jet fuel are mostly manual, which is not only labor-intensive but also easily causes harm to the operator due to the toxicity of the reagents. The subsequent test process is still relatively complicated. In this regard, an automatic jet fuel total acid value tester can be designed. By setting up an automatic lifting and stirring mechanism, automatic aeration, titration and stirring of the sample can be achieved, simplifying the test steps. By setting up an image processing system, errors caused by human color judgment can be avoided. Utility Model Content
