Around Lubricant Co., Ltd. of Shenzhen City (www.sz-run.com) is located in Shenzhen City, Guangdong Shenzhen Nanshan District No. 68 before the sea waterfront Avenue, Contact: Mr. He engine is the heart of the car, there are a lot of friction between the movement of the engine metal surface, these multi-purpose sports faster Fox EP2 grease, poor environment, the temperature can reach 400 ℃ ~ 600 ℃, in the face of such harsh conditions, only qualified oil in order to reduce the wear of engine parts, extending Fox XXL multipurpose grease life, then what qualified lubricants to meet the demands? That is what is the role of the six oil? 1, antifriction lubricating the engine is running, if some parts are not properly lubricated friction will produce dry friction. Practice has proved that the dry friction heat generated short enough to melt metal Fox SL multipurpose grease, mechanical damage and even death card. It must give good lubrication for engine friction parts. When the oil flows to the friction portion, the adhesive will form a film on the friction surface to reduce the friction resistance between the parts, and the strength and toughness of the film to play a key role in lubrication. 2, heat is cooled by cooling the fuel oil combustion in the engine produced only a small portion for the power output and the drive mechanism and the auxiliary friction on consumption, with most of the remaining heat of the exhaust gas to the atmosphere except foreign, will be Engine cooling medium take part. Engine must be drained of excess body heat, otherwise the engine will burn due to high temperature. In this regard by the engine cooling system to accomplish the other hand rely on oil to absorb heat from the cylinder, piston, crankshaft and other surfaces in the distribution of various types of oil to the sump of the test items subdivided down, there are hundreds of detection projects different test items may also require different equipment. Such as viscosity, there is the kinematic viscosity, Engler viscosity dynamic viscosity, etc., can be divided into downstream detection method, countercurrent method. Moisture detection has a simple hot plate, there are steamed in France - Karl Fischer titration. Lubricants After assessing their special physical and chemical properties, but also for some general simulation bench, including some engine tests before being put into use after the adoption. With extreme pressure anti-wear properties of the oil must assess its extreme pressure anti-wear properties. Commonly used test machine has Timken ring block test machine, FZG gear testing machine, Falaikesi testing machine, fatigue testing machine rollers, which are used to assess the ability of extreme pressure load of oil or anti-wear properties. Evaluation of the application of oil extreme pressure performance test machine is the most common four-ball machine multipurpose grease, oil it can assess the maximum nonseizure load, sintering load, long-term wear and abrasion index comprehensive. These indicators reflect the extreme pressure and antiwear properties of the oil to some extent, but it is actually used in many cases, the performance was no good correlation. This method is simple only because it is still widely used. In the high-end vehicle gear oil standard, requiring a series of assessment gear bench, including low speed high torque, low-speed torque gear test; gear test with impact load; gear box oil corrosion and thermal oxidation stability test gear trials.
