Castrol AWH-M_ Miles Castrol lubricants _ AWH-M46 hydraulic oil supplied by Miles lubricants. Castrol AWH-M, Miles lubricants, Castrol AWH-M15 hydraulic oil Lubricant Co., Ltd. of Shenzhen City, Miles (www.sz-run.com) 2014 Miles been newly launched to upgrade the future development of oil showed the following trend: a device able to adapt to two higher power, low power consumption and good fuel economy products harmless for the environment, safe lubricants will be widely used. Third, multi-level engine oil, high-grade engine oil, gasoline and diesel engine oil GM, better adapted to the multi-purpose lubricant equipment and technology, a variety of special lubricants will get rapid development. Fourth, the high-performance additives, particularly complex additives, nano-materials, complexing agent plus extreme pressure anti-wear agents will be more widely used; lubricant additives total dosage will be gradually reduced. Fifth, the base level of oil continues to increase Castrol AWH-M32 hydraulic oil, Ⅱ, Ⅲ base oils heavy use, biodegradable base oils, synthetic base oils have a wide range of applications; fundamental base oil toward good thermal oxidation stability, shear Cean qualitative, low sulfur, low phosphorus, low viscosity, low volatility, high viscosity index, environment-friendly direction. After selecting the appropriate hydraulic oil viscosity selected varieties, but also to determine in what order the viscosity of the hydraulic oil level of the hydraulic system to work in the best condition. Although the choice of the high viscosity of the lubricating Advantageously, the resistance of the system increases, the pressure loss increases Castrol AWH-M, resulting in increased power loss Castrol AWH-M68 hydraulic oil, rose oil, hydraulic operation instability, noise occurs . High viscosity at low temperatures also cause difficulties to start absorbing even cause an interrupt when the cold start fuel, equipment failure occurs. Conversely, when the hydraulic system is a low viscosity, will increase in the hydraulic equipment, external leakage, instability of the hydraulic system pressure Castrol AWH-M46 hydraulic oil, the pressure is reduced, the hydraulic operating means is not bit, the wear of the pump will lead to serious increased. ? First selected according to the viscosity level of the pump determines the type, each type of pump has its optimum viscosity range applies: vane pump 25 ~ 68mm2 / S, piston and gear pumps are 30 ~ 115mm2 / S. The minimum operating viscosity vane pump should not fall below 10mm2 / S, while the viscosity should not exceed the maximum starting 700mm2 / S. The minimum operating viscosity should not be less than the piston 8mm2 / S, the largest startup viscosity should not exceed 1000mm2 / S. Gear pumps required viscosity, viscosity should not fall below the minimum operating 20mm2 / S, the largest start-viscosity up to 2000mm2 / S. ? Also consider viscosity grade selection conditions of the pump, the high temperature and pressure of the hydraulic system to use a higher viscosity of the hydraulic oil, a good lubricating property can be obtained, on the contrary, a lower temperature and pressure, should the use of lower viscosity, thus saving energy. Also, consider the viscosity of hydraulic oil in the system should not exceed the minimum temperature maximum viscosity pump. Table 3 lists the pump at different pressures and temperatures the viscosity of the selection.
