Diesel oil - Automatic determination of moisture
Diesel will contain some water, not artificial, not deliberately put into the business.
Tell us why diesel has water. When you know these reasons, you will understand the above sentence
Why did you say that?
(a) diesel oil has water reasons
1. Technical reasons. From a technical point of view, all oil tankers in the process of loading and unloading,
Finally, water is jacked out of the receiving pipeline, so there is water in the tank and a water cushion, that is
There is water at the bottom of every tank in the oil depot, which is objective.
2. Time. Sometimes resources are tight, oil precipitation time is not long enough or oil tank to tank
The process contains trace moisture.
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. Affected by thermal expansion and contraction, it can also absorb moisture from the air.
Diesel has water in it, and if it's just a little bit, it can start, it doesn't matter much; If there is more water, it will not work, affecting the smooth idle speed and acceleration capacity, mainly burning the engine, so it is necessary to detect whether the water content is high enough, and the water content is not more than 0.03%.
SH103 Moisture tester adopts the principle of Karl Fischer Coulomb titration and 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 and accurate and reliable analysis results. It is a high quality analytical instrument for petroleum, chemical, electric power, environmental protection, medicine, scientific research and other departments. The instrument uses a 32-bit embedded microprocessor as the main control core, embedded in a mini-operating system; The instrument has constant current detection, double circuit balance titration function; The electrolytic cell adopts waterproof sealing design; Support multiple calculation formula, in line with standard GBT11133 and ASTMD 0304.
