Automatic determination of diesel moisture solution
There will be some water in diesel, not man-made, not deliberately put into the business.
Tell us the reasons why diesel oil has water, when you know these reasons, you will understand the above sentence
Why did you say that?
(1) The reason why diesel has water
1. Technical reasons. From a technical point of view, all tankers in the process of loading and unloading,
Finally, there is water in the oil collection line, so there is water in the tank and a water cushion, i.e
It is an objective existence that there is water at the bottom of each tank.
2. Time. Sometimes resources are tight, the oil deposit time is not long enough or the oil tank is rotated
The process contains a trace of water.
3, the nature of oil. Petroleum is mainly composed of alkanes, cycloalkanes, alkenes and aromatic hydrocarbons.
The aromatic hydrocarbon in the oil has a strong water absorption, easy to absorb water from the air.
4. Physical reasons. As heat expands and cold contracts, it can also absorb moisture from the air.
Diesel has water in it, and if it's just a little bit, it can start, and it doesn't make much difference; If the water is more than no, affect the idle speed stable, acceleration ability, mainly burning the engine, so it is necessary to detect the high content of water is not exceeding the standard, and the water content is not greater than 0.03%.
SH103 micro moisture tester adopts the principle of Karl Fischer Coulomb titration and adopts microcomputer automatic control. Compared with similar products at home and abroad, it has the advantages of high sensitivity, fast electrolysis speed, short balance time, accurate blank deduction, accurate and reliable analysis results. It is a high-quality analytical instrument for petroleum, chemical industry, electric power, environmental protection, medicine, scientific research and other departments. The instrument uses 32-bit embedded microprocessor as the main control core, embedded mini operating system; The instrument has constant current detection, double circuit balance titration function; The electrolytic cell adopts waterproof seal design; Support multiple calculation formulas, in line with the standard GBT11133 and ASTMD 0304.
Karl -- Fischer Coulometric method, for different substances for the determination of trace moisture, is one of the most reliable method, in line with GB/T11133, the trace moisture tester successfully applied this method, and the use of microcomputer control, its analysis speed, high accuracy, LCD color screen Chinese display, automatic printing, dual CPU design, Blank current automatic deduction function and the instrument fault self-diagnosis, menu selection and other functions, in order to achieve better operation and use, with simple operation, automatic analysis instrument. It is an instrument for the analysis of oil moisture
