    Important Characteristics of Grease

    The structure of grease determines that it has different characteristics from liquid lubricating oil, including rheological properties (non-Newtonian edge contact) Mainly manifested in: 1. When not subjected to external forces, it maintains a certain shape and does not automatically lose its shap...

  • Why Engine Oil Turns Black?

    Why Engine Oil Turns Black?

    Firstly, the blackening of lubricating oil is related to the fuel used. The higher the olefin and sulfur content in the fuel, the easier it is to form sludge. Secondly, when changing the lubricating oil, do not clean the inside of the engine and the oil pan. The sludge in the previously used lubr...

    Simple Identification of Hydraulic Oil

    1. Moisture content Combustion method. Dip a small amount of the oil to be tested with clean and dry cotton yarn or paper, and then ignite it with fire. If there is a cracking sound or flashing phenomenon, it indicates that the oil contains a lot of water. 2. Impurity content Filter paper detecti...

  • Viscosity and Strength Limits of Grease

    Viscosity and Strength Limits of Grease

    The viscosity and strength limits reflect the characteristics of non-Newtonian fluids in lubricating grease, that is, the fluidity changes with shear velocity. The viscosity of grease is usually represented by apparent viscosity or similar viscosity. When explaining the viscosity, temperature and...

  • What Is the Relationship between Oil Viscosity and High Temperature?

    What Is the Relationship between Oil Viscosity and High Temperature?

    Oil viscosity is the most important performance indicator for measuring the fluidity of oil in various states. The lower the viscosity of the engine oil (with a “thinner” feel), the thinner the oil film and better fluidity. However, the ability to resist shear is weaker under high te...

  • The Effect of Lubricating Oil Cleanliness and Dispersion

    The Effect of Lubricating Oil Cleanliness and Dispersion

    During the use of lubricating oil, some carbon particles and smoke generated by fuel combustion will enter it, as well as some dust from the air. In addition, some acidic substances generated by the high-temperature oxidation of the lubricating oil itself will generate carbon deposits and sludge ...

    How to Simply Identify Poor Quality Brake Fluid?

    There are three simple methods to roughly determine the quality of brake oil. Method 1: Smell it. If there is obvious odor or essence smell, there is a quality problem. Method 2: Try to “burn” on your hands. Pour a small amount of brake oil onto the palm of your hand, if there is no h...
