What is the low temperature fluidity of diesel oil related to?
The flow performance of diesel oil at low temperature is not only related to the normal supply of diesel fuel system, but also closely related to the storage and transportation of diesel oil at low temperature.
The low temperature fluidity of diesel oil is related to its chemical composition. The higher the n-alkane content is, the worse the low temperature fluidity is.
The freezing point and cold filter point are used to evaluate the low temperature fluidity of diesel oil in China.
According to the quality standard of light diesel oil in China, 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. R & D and production) is based on the national standard GB/T510 "petroleum product freezing point determination method" and SH/T 0248 as the basis, the use of contemporary advanced technology, set mechanical, optical, electronic and computer technology in one.
Can automatically complete the freezing point of petroleum products, cold filter point test, the instrument adopts photoelectric detection technology, glass tube automatic tilt method, imported compressor refrigeration system to ensure that the required refrigeration depth.
