Light diesel oil distillation process overview and test method standard
50% distilling temperature: indicates the content of light fraction in diesel oil. If the temperature is low, the fraction is light, evaporation and combustion speed is fast, and the engine is easy to start.
Too light a diesel fraction is also detrimental to combustion. Because the light fraction of diesel oil cetane value is low, long ignition delay period, easy to evaporate, easy to produce detonation when firing.
90% distillation temperature: said the content of heavy distillate, the temperature is high, heavy distillate, spray atomization bad, evaporation is slow, combustion is not complete, under high temperature thermal decomposition and the generation of carbon, so that the exhaust with black smoke, increase oil consumption, and increase mechanical wear.
SH6536 automatic distillation tester adopts color LCD display screen, Chinese menu man-machine dialogue, wizard operation, the determination process is all automatic. It is designed according to the requirements of national standard GB/T6536 "Petroleum Products Distillation Determination method" and ASTMD 86. It adopts embedded computer, imported industrial computer, 12.1 inch LCD touch screen, friendly man-machine dialogue interface and convenient test operation. Using single chip microcomputer and intelligent control technology, the distillation test process of heating and cooling, distillation liquid level tracking, distillation rate control, recovery liquid volume control, temperature recording, test results printing, all automatically completed.
