Total wear system oil L-AN
Mechanical special oil consumption system oil L-AN classification:
Class L products are divided into 19 groups, of which Group A oil is used in the full loss system, but the oil used in the total loss system is not only Group A oil, but also the oil of the reciprocating compressor in Group D, Group G rail oil, P group air tool oil and Z group steam cylinder oil are all loss system oils. China classifies L-class A products into three varieties: AB, AN and AY.
L-AB oil is made from refined mineral oil and contains bitumen or additives to improve its adhesion, extreme pressure and corrosion resistance. It is mainly used for the lubrication of open gears and rope surfaces. L-AB oil is similar to L-CKJ open gear oil in Group C and can be used interchangeably, so L-AB oil is not produced in China.
L-AN oil is made from refined mineral oil. It can also be added with a small amount of pour point depressant. It is divided into 5 to 150 viscosity grades according to the central value of its 40 °C kinematic viscosity. It is mainly used in light-load, old-fashioned, general-machine full-loss lubrication systems or oil-bath lubrication systems with short oil change intervals. It is not suitable for circulating lubrication systems.
L-AY oil is an unrefined mineral oil with a low pour point and sometimes withdrawn oil (a by-product of the refined lubricating oil process) in order to improve adhesion. It is suitable for the lubrication of railway truck sliding bearings. It is divided into three grades of winter, summer and general, and is used by the railway department.
Mechanical special oil consumption system oil L-AN main performance:
It is prepared by deep refined mineral oil or synthetic oil as base oil and added with high-efficiency compound additive. It has good oxidation stability and thermal stability, good resistance to high temperature deposition, good low temperature fluidity, high flash point, Lower volatility. Meet the German DIN515221998 specifications.
Mechanical special oil consumption system oil L-AN main use:
L-QB is suitable for open oil tanks, closed systems with or without forced circulation. L: QC, L-QD are suitable for closed systems with forced circulation.
Mechanical special oil consumption system oil L-AN implementation standards;
GB23971-2009 organic heat carrier. It is divided into three varieties: L-QB, L-QC and L-QD. L-QB has two grades of 280 and 300. L-QC has 310 and 320 brands. L QD has brands such as 330, 340, and 350.
