A solution for automatic determination of diesel moisture
Diesel oil will contain some water, not artificial, 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?
(a) the cause of water in diesel oil
1. Technical reasons.
From a technical point of view, all tankers in the process of receiving and unloading,
Finally, there is water ejecting in the oil receiving pipeline, so there is water in the oil tank and a water cushion layer, that is
There is water at the bottom of each tank, which is an objective existence.
2, the reason of time.
Sometimes the resources are tight, the oil settling time is not long enough or the oil tank is transferred
The process carries a trace of water.
3, the nature of oil products.
Petroleum is mainly composed of alkanes, cycloalkanes, alkenes and aromatic hydrocarbons.
The aromatic hydrocarbons in the oil products have strong water absorption, easy to absorb water from the air.
4. Physical reasons.
Affected by thermal expansion and contraction, it can also absorb moisture in the air.
Diesel has water in it, if it's just a little bit, it can start, it doesn't have much impact;
If there is too much water, it will not work, which will affect the stable idle speed and acceleration ability, mainly due to the burning of the engine. Therefore, it is necessary to detect whether the high moisture content exceeds the standard and stipulate that the water content is no more than 0.03%.
According to the principle of Carl Fischer Coulomb titration, SH103 micro moisture tester 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, etc.
It is a high quality analytical instrument for petroleum, chemical, electric power, environmental protection, medicine, scientific research and other departments.
The instrument adopts 32-bit embedded microprocessor as the main control core, embedded in the mini-operating system;
The instrument comes with constant current detection, double circuit balance titration function;
The electrolytic tank adopts waterproof and sealed design;
Support multiple calculation formulas, in line with the standard GBT11133 and ASTMD 0304.
Carl-Fischer Coulomb method, the determination of trace moisture of different substances, is one of the most reliable methods, in line with GB/T11133, the trace moisture analyzer successfully applied this method, and the use of microcomputer control, its analysis speed is fast, high precision, LCD screen Chinese display, automatic printing, dual CPU design,
Blank current automatic deduction function and instrument fault self-diagnosis, menu selection and other functions, to achieve better operation and use, with simple operation, automatic analysis instrument.
It is an instrument for oil moisture analysis
