The viscosity grades of commonly used anti-wear hydraulic oil are 32 #, 46 # and 68 #. L-HN anti-wear hydraulic oil is suitable for low, medium and high pressure hydraulic systems of hydraulic equipment such as engineering, construction, mining and plastic processing, especially for high speed, high pressure and imported equipment hydraulic systems with requirements for oil cleanliness. It can also be used for lubrication of other low and medium load gear rotating devices, bearings and other industrial machinery.
The ashless antiwear hydraulic oil is applicable to the hydraulic system of metallurgy, engineering, mining machinery, marine auxiliary machinery and other fields or industries. Such as: the hydraulic system of furnace top machinery, forging, die-casting, steel rolling, extrusion, rolling, coiling and other machinery. Hydraulic systems for lifting, loading, excavating, shoveling, compactors, concrete, rock drilling and pavement machinery. Hydraulic system for lifting, crushing, perforating, mineral processing and special mine hoisting equipment.
What is the difference between ordinary anti-wear hydraulic oil and ashless anti-wear hydraulic oil? First of all, antiwear Hydraulic Oil Additive system is divided into ashy (zinc) formula and ashless formula.
First, the ashy type is: zinc containing main agent, ZDDP, zinc dialkyl dithiophosphate, whose standard is 0.03% zinc content in oil.
Second, the ashless type is: zinc free. The advantage of ashless type is that it does not contain zinc element and will not react with parts with silver.
Because many parts, such as valves, are made of silver plated materials, the zinc element will react with the silver plating to replace the silver and damage the parts. However, this problem will not occur if you use the ashless anti-wear hydraulic oil, because the ashless anti-wear hydraulic oil does not contain zinc, so it will not react with silver and damage parts. What are the advantages of ashless anti-wear hydraulic oil! First of all, the ashless anti-wear hydraulic oil has a unique zinc free anti-wear formula, which effectively protects the silver containing parts and extends the service life of the pump using silver and silver plated parts. Secondly, the oil products have better hydrolysis stability, which can also provide good protection when the system is polluted by a small amount of water. Finally, the excellent anti foaming and air release properties ensure that the system transfers static pressure energy sensitively, accurately and stably. Tips for using ashless anti-wear hydraulic oil: 1. Oil products with proper viscosity shall be selected according to equipment oil regulations 2. During the use and storage of ashless anti-wear hydraulic oil, foreign matters shall be prevented from pollution, and mechanical impurities and water shall be strictly prevented from mixing 3. Keep the oil tank clean. Clean the oil tank and oil circuit when changing oil 4. Do not mix with other oils, and do not mix different types of anti-wear hydraulic oils 5. This product is strictly prohibited from contacting with internal combustion engine oil.
