Weihai metal processing oil, Miles lubricants, Castrol 603 metalworking lubricant oil supplied by Miles. Weihai metal processing oil, Miles lubricants, metal processing oil Castrol 603 Miles Lubricants Ltd. of Shenzhen City (www.sz-run.com) 2014 upgrade been newly introduced water-based rust inhibitor, a new technology, Castrol 603 high performance metal processing oil, environmentally friendly water-soluble anti-rust solution, containing a selection of high-rust agent. It can form a very light soft lipid membrane, this membrane is usually only provided by the solvent-based rust preventive oil. Castrol environmentally friendly water-based rust inhibitor products · · No risk of fire trap VOC compliance with regulatory requirements and safety, easy handling & usage of diverse workpieces - suitable for immersion, spray wash or use without injury to the operator · · · not consume oxygen helps on providing excellent corrosion protection of ferrous metals by ISO 14001 environmental certification · · can no impact on the process / production number. Humidity of 20-30 ℃ using suitable metal processing oil, solvent formulations Low foaming, the workpiece can be immersed in the use of this product, or low pressure spray and rinse liquid spray Water-soluble rust can form a thin protective film · Drying short time. 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, resulting in increased power loss, increased 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, pressure drop, no bits to the hydraulic operating means, causes severe wear of the pump increases. ? 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 Castrol 983SW metal processing oil, and start the viscosity should not exceed the maximum 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. ? Optional pump also consider viscosity grade conditions, high temperature and pressure of the hydraulic system to choose a higher viscosity of hydraulic oil, a good lubricating property can be obtained Castrol B27/30 metal processing oil, on the contrary, the temperature and pressure low, low viscosity should be used, which can save 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.
