Around the lubricating oil Shenzhen principle is to reduce friction, so-called friction means when the relative motion of two surfaces, a relative displacement occurs in the external force when there is a contact surface opposing Castrol synthetic gear oil, called the friction surface. Many different types of friction phenomena have external friction, internal friction, sliding friction, rolling friction, dry friction, boundary lubrication friction, lubrication fluid friction, mixed lubrication friction. Apparent phenomena such as friction caused by high temperature, noise, wear, etc.. Which is the most harmful wear, abrasion have adhesive wear, abrasive wear, corrosion, wear, abrasion and other types of surface fatigue Castrol synthetic gear oil EP30, which directly affect the normal operation of machinery and equipment and even failure. The role of oil is in the friction between the two form a protective film to prevent direct contact between the metal and the metal, thereby cushioning the effect of friction, lubricates Castrol synthetic gear oil PG150, reduce wear and fraternity household machinery normal operation. This protective film may be physically adsorbed film or a chemically adsorbed film or the oxide film thickness and strength of the film directly affect lubrication. Common lubricating oil between the main friction surface is formed as a protective film layer of synthetic gear oil Castrol EP460, lubricating oil is to rely on the theoretical additive effect of the friction surface of the protective film is formed in the adsorption, the base oil itself plays only additive between the carrier and the friction surface sealing, lubricating oil film has retreated to a secondary position. Grease and oil has the following advantages: l In the metal surface with good adhesion, easy to drain; the sealed portion difficult to use, to simplify the structure of the lubrication system. 2 anti-rolling at a high load and impact load, there is still a good lubricating ability. 3 Long lubrication cycle, without regular supplement, replace, and the metal parts have some rust, relatively lower maintenance costs. 4 wide temperature range suitable for a wide working conditions. Thus, the vehicle is not suitable for the site using liquid lubricant grease can be used. On the other hand, the viscosity of the grease is large, the running resistance, the power loss is great. Poor flowability of grease, substantially having a cooling effect of the liquid lubricant and cleaning, easy to remove the solid impurities mixed. In addition, the use of grease in some parts of greasing more difficult for fat. Therefore, the use of grease parts subject to certain restrictions.
