润滑油基本原理（Fundamentals of lubricating oils） The basic principle of lubricants.Txt the most precious thing in the world is not what can never be obtained or what has been obtained, but what you have gained and may lose at any moment! Love is a lamp, while friendship is the shadow. When the lamp is off, you will find the shadow everywhere. Friend is who can give you strength at last.

Fundamentals of lubricating oils Why should we use grease? Why should we use grease? Cooling, cleaning, sealing and lubrication The function of lubricating oil - function of lubricating oil - cooling Physical viscosity) liquid (viscosity, viscosity, stability, heat transfer) (stable deposition, stable deposition) Function of lubricating oil - clean Fluid properties (viscosity, fluid viscosity), viscosity, stability, emulsifying, detergency, lubricity Function of lubricating oil - function of lubricating oil - sealing Viscosity (solubility and stability = efficiency, solubility and stability), solubility and stability, lubricity Lubricating oil function - lubricating oil function - Lubrication Structural additives in viscosity, miscibility, solubility, lubricity, chemistry Effectiveness of impact lubricants - a major factor affecting the effectiveness of lubricants The viscosity stability of lubricants The main factors affecting the lubrication interface Viscosity load rate Load speed viscosity Coefficient of friction at the lubrication interface Definition of lubrication in zone three (boundary / lubrication / hydraulic / dynamic three lubrication definitions) Hydrodynamic lubrication Hydrodynamic lubrication friction coefficient boundary lubrication Viscosity, x, velocity, velocity viscosity Hydrodynamic W N Minimize wear and maximize efficiency Viscosity level - ISO level Industrial lubricants; ISO
