(1) According to the requirements of GBT7631.1-2008, the serial number of lubricating oil consists of type, variety and data, and its writing type is: category + variety + data.
(2) Type refers to the classification of petroleum products. Lubricant is one of petroleum products.
(3) Variety refers to the classification of lubricating oil. The agent steam turbine oil manufacturers are classified according to their application sites, and the corresponding English letters mean: A——full loss system software; C——transmission gear; D——refrigeration compression Machine; E——gas turbine; F——motor stator, rolling bearing, clutch; G——guide wheel; H——hydraulic transmission system; M——laser cutting of metal material; P——pneumatic tool; T—— Turbine generator; Z—steam cylinder, etc., is the capital of the first letter of the variety column. In fact, there will be one or several other English letters in the variety column to indicate the further subdivision type of the variety.
(4) The number means the viscosity grade of the lubricating oil, and its marked value is equal to 40 °C (some are the production batch number, but it must be specified, otherwise it refers to 40 °C) is the middle kinematic viscosity value, the enterprise is mm2/s, according to GB/T141 " "Industrial Liquid Lubricant Viscosity Value" requirements, its marked value is equal to 40 ℃ (some production batch numbers, but must be specified, otherwise it refers to 40 ℃) is the middle kinematic viscosity value, the enterprise is mm2/s, according to GB/T14141 "Industrial Liquid Lubrication" Agent Viscosity Value" requirements, there are 2.3.7.10.22.480.6.680.1000.1500.
Example: L-AN100, which means the full-consumption system software lubricating oil with a viscosity level of 100mm2/s for professional turbine oil, the kinematic viscosity at 40℃ is 90~110mm2/s, and the intermediate kinematic viscosity is 100mm2/s.
