The flow performance of diesel oil at low temperature is not only related to the normal fuel supply system, but also has a close relationship with the storage and transportation of diesel oil at low temperature. The low temperature fluidity of diesel oil is related to its chemical composition, and the higher the content of n-alkanes, the worse the low temperature fluidity. The indexes for evaluating diesel oil's low temperature fluidity in China include freezing point and cold filter point. According to China's light diesel quality standard, the freezing point is determined according to GB/T510, and the cold filter point is determined according to SH/T0248.
SH0248C automatic freezing point cold filter point tester (Shandong Shengtai Instrument Co., LTD.) is based on the national standard GB/T510 "Petroleum products freezing point determination method" and SH/T 0248, using modern advanced technology, set mechanical, optical, electronic and computer technology in one, Can automatically complete the freezing point of petroleum products, cold filter point testing, the instrument uses photoelectric detection technology, glass tube automatic tilt method, imported compressor refrigeration system to ensure that the refrigeration depth requirements.
