　　液压油有7种型号。

　　根据《液压油按国标(GB 7631.2-87)》液压油分类中可分为7种型号，即HH、HL、HM、HR、HG、HV、HS；其中HM、HV、HS最为常见的三种液压油型号；同时，液压油是一种传递压力(动敏困力)的专用油，在液压系统中起着能量传递、抗磨、系统润滑、防腐、防锈、冷却、密封等作用。

　　1、HH液压油是一种不含任何添加剂的矿物油；这种油虽己列入分类之中,但在液压系统中己不使用。因为这种油安定性差、易起泡,在液压设备中使用寿命短。

　　2、HL液压油的用途是用于对于润滑油没有特殊要求，环境温度在零摄氏度以上的各类机床的轴桥扰念承箱、低压循环系统等等方面的润滑作用。这类产品一般都具有非常好的密封适应性，最高使用温度可达80摄氏度。There are 7 types of hydraulic oil. According to the classification of hydraulic oil according to GB 7631.2-87, there are seven types of hydraulic oil, namely HH, HL, HM, HR, HG, HV, HS, hydraulic oil is a kind of special oil for transmitting pressure, which plays an important role in hydraulic system, such as energy transfer, anti-wear, system lubrication, anti-corrosion, anti-rust, cooling and sealing. HH hydraulic oil is a mineral oil without any additives; it is classified but not used in hydraulic systems. Because this kind of oil stability is bad, easy froth, in the hydraulic equipment service life is short. 2. HL hydraulic oil is used for lubrication of axle axle disturbing bearing box, low pressure circulation system and so on for all kinds of machine tools with no special requirement for lubricating oil and environment temperature above zero degrees centigrade. These products are generally very good sealing adaptability, the highest temperature up to 80 degrees Celsius.
