"The main indicators of lubricating oil performance include viscosity index, humidity, freezing point, flash point, oxidation, copper corrosion, foam resistance, shear resistance and extreme pressure resistance.
Viscosity Index ": Refers to the degree to which the viscosity of lubricating oil changes with temperature. High viscosity index lubricating oil can maintain a more stable viscosity under temperature changes, making it suitable for a wider range of working environments.
Moisture: The moisture content in lubricating oil can affect its characteristics. Excessive moisture can cause lubricant emulsification, affecting lubrication effectiveness and equipment lifespan.
Condensation point ": Refers to the lowest temperature at which lubricating oil begins to flow when cooled to a certain temperature. The lower the solidification temperature, the better the low-temperature fluidity of the lubricating oil.
Ignition point ": Refers to the minimum temperature at which lubricating oil can release enough combustible gas, which mixes with air during heating to form an explosive mixture and burns in an open flame. High flash point grease is safer and has lower volatility.
Oxidation stability "refers to the ability of lubricating oil to maintain stable characteristics under high temperature and oxidation conditions. Lubricating oil with good oxidation resistance has a longer service life.
Copper plate corrosion ": Refers to the degree of corrosion of copper materials by lubricating oil. Lubricating oil with less corrosiveness can better protect equipment.
"Anti foam": refers to the ability of lubricating oil to form foam during operation. Lubricating oil with good anti foam performance can reduce the influence of foam on lubrication effect.
Shear stability: Refers to the ability of lubricating oil to maintain stable viscosity and performance under high temperature and high shear conditions.
Efficiency under extreme pressure: refers to the ability of lubricating oil to provide sufficient lubrication under extreme pressure. Lubricating oil with good performance under extreme pressure is suitable for high load and high-speed equipment.
These indicators collectively determine the performance and efficiency of lubricating oil. The selection of suitable lubricating oil should be determined based on the specific working environment and equipment requirements.
