details The hydraulic system oil has excellent anti-wear and anti-rust handling properties;Excellent resistance to bubbles and gas release;Excellent emulsion resistance;Excellent rubber seal adaptability。Hydraulic system oil is a part of the application, but in different hydraulic system oil, the application of oil is not the same, generally there are 3 types of oil, such as mineral oil type hydraulic oil, emulsified hydraulic oil, raw forming hydraulic oil, each of these 3 types of hydraulic oil is divided into many kinds of oil, the following:
1.Ultra-low temperature hydraulic oil: anti-wear hydraulic oil with preservatives, improve the viscosity and temperature characteristics, can be used in the working temperature of -40~-20℃ high pressure system。
2.General hydraulic oil: professional mineral oil preservative, improve the anti-oxidation and anti-rust treatment characteristics, suitable for the general machine equipment in the room of the medium bottom pressure system。
3.Anti-wear hydraulic oil: general hydraulic oil preservative, improve anti-wear characteristics, suitable for construction machinery equipment, car hydraulic system oil。
4.Total depletion system oil: shallowProfessional typeMineral, anti-oxidation, anti-foam characteristics are weak, the key is used for mechanical equipment wetting, can be used as a hydraulic replacement oil, generally used for not too high bottom pressure system。
5.High viscosity index value hydraulic oil: general hydraulic oil preservative, improve viscosity temperature characteristics, VI detection value above 175, suitable for ultra-low temperature systems with special requirements for viscosity temperature characteristics, such as CNC lathe hydraulic system oil and its brass or silver components of the hydraulic system。
6.Turbogenerator oil: deep professional mineral oil with preservatives, improve anti-oxidation, anti-foam and other characteristics, for turbogenerator professional oil, can be used as a hydraulic replacement oil, suitable for general hydraulic system oil。
7.Hydraulic rail oil: anti-wear hydraulic oil with preservatives, improve the stick-slip characteristics, suitable for CNC lathes in hydraulic and rail wetting shared system。
1.Water oil emulsion oil: high water base liquid, the characteristics are flame retardant, good viscosity and temperature characteristics, reasonable anti-rust treatment ability, poor wettability, easy to leak。It is suitable for the system with large amount of oil and serious leakage。
2.Oil-water emulsion oil: both mineral typeHydraulic oilThe anti-wear, anti-rust treatment characteristics, but also has fire resistance, applicable to the high pressure system with anti-fire provisions。
Forming hydraulic oil
1.Water-glycol liquid: flame retardant, viscosity temperature characteristics and corrosion resistance, can be applied at -20-50℃, suitable for low-medium system with anti-fire provisions
2.Phosphate ester liquid: flame retardant, wetting, anti-wear characteristics and excellent oxidation resistance, can be applied at -20-100℃, defects are harmful。It is suitable for high pressure fine hydraulic system with anti-combustion provisions。
