Supply of how to properly repair excavator hydraulic oil temperature is high and selection

Supply of how to properly repair excavator and select high temperature hydraulic oil, Troubleshooting: [139] - [9639] - [3931], Mengjing Li 1, other comprehensive performance excavator hydraulic oil due to large hydraulic excavator hydraulic system Working pressure is high, allowing maximum operating oil temperature of hydraulic oil is also high (about 90 ℃), so in order to ensure the hydraulic system to work properly in the normal drain intervals, requires lubrication system selected oil oxidation stability, anti-wear, rust and corrosion resistance, anti-emulsification, anti-foam, shear Cean qualitative and extreme pressure load and other aspects of good quality. Excavator weakness, excavator hydraulic failure, excavator distribution valve failure, multi-valve malfunction excavators, excavators, weakness, excavators card machines, excavators did not force, excavators and slow, these faults are not terrible. Digging machine repair, or to the formal digging machine repair outlets good (Southwest United excavators Maintenance Co., Ltd., where the well-equipped, high level of technology, service assurance 2, excavator hydraulic oil viscosity to determine the principles of hydraulic oil viscosity is In consideration of the hydraulic circuit operating temperature and efficiency of the premise, so (for pumps and motors and other components) in the best range of hydraulic oil viscosity; and Environmental lowest temperature corresponding short cold start viscosity; and correspond to short allowed highest viscosity oil leakage at 90 ℃ .3, excavator hydraulic oil viscosity index of the index a more direct reflection of the oil viscosity with temperature change of nature (ie viscosity-temperature characteristics of the oil), viscosity index oil higher, indicating a lesser extent, the kind of oil viscosity with temperature change; the other hand, the larger viscosity index known foreign manufacturers (such as Mobil, Shell, etc.) are anti-wear hydraulic oil, domestic advanced anti-wear hydraulic. oil viscosity index VI = 95 or so. The foreign production of high viscosity index hydraulic oil (and multigrade engine oil viscosity index are. This is for the use of large-scale imports of hydraulic excavators and the use of domestic hydraulic oil (or engine oil for hydraulic oil with) the user must pay special attention. viscosity index oil will reduce the ambient temperature range adapted to reduce, if not non-use, the oil should Manufacturers relevant information on the use of oil shall make the appropriate adjustments, if necessary It should also change the value of the device related settings (such as extreme temperature, etc.). how to properly repair excavator hydraulic oil temperature is high and select the preferred fly excavator plant maintenance more professional and more at ease.
