济宁微山县马坡镇代理壳牌液压油-压缩机油液压油就是利用液体压力能的液压系统使用的液压介质，在液压系统中起着能量传递、抗磨、系统润滑、防腐、防锈、冷却等作用。对于液压油来说，首先应满足液压装置在工作温度下与启动温度下对液体粘度的要求，由于润滑油的粘度变化直接与液压动作、传递效率和传递精度有关，还要求油的粘温性能和剪切安定性应满足不同用途所提出的各种需求。液压油的种类繁多，分类方法各异，长期以来，习惯以用途进行分类，也有根据油品类型、化学组分或可燃性分类的。这些分类方法只反映了油品的挣注，但缺乏系统性，也难以了解油品间的相互关系和发展。Hydraulic oil is the hydraulic medium used in the hydraulic system using the liquid pressure energy. It plays the role of energy transfer, anti-wear, system lubrication, anti-corrosion, anti-rust, cooling and so on. For the hydraulic oil, it is necessary to satisfy the requirement of the viscosity of the liquid in the working temperature and starting temperature of the hydraulic device, because the viscosity change of the lubricating oil is directly related to the hydraulic action, the transmission efficiency and the transmission precision, the viscosity-temperature property and shear stability of oil are also required to meet the requirements of different applications. Various types of hydraulic oil, classification methods vary, for a long time, the customary use of classification, but also according to the type of oil, chemical composition or flammability classification. These classification methods only reflect the oil earned note, but lack of systematic, and it is difficult to understand the oil inter-relationship and development.
