揭阳惠来神泉-仙庵壳牌液压油-齿轮油销售处摘要:液压油是液压传动与控制系统中用来传递能量的工作介质，同时具有润滑、冷却和防锈作用。液压油具有良好的抗磨性能，使用后能确保设备寿命长，型号一共有七种，分别为HH、HL、HM、HR、HG、HV、HS，其中46、48这两个牌号代表的是HL液压油，它们比较起来哪个好呢？一起到文中来看看吧！一、液压油有几种型号

　　液压油分纳野裂为7种。在GB/T7631.2一2003分类中的HH、HL、HM、HR、HG、HV、HS液压油均属矿油型液压油。46、48这两个牌号代表的是HL液压油。以下是更多相关的介绍:

　　1、HH液压油:HH液压油是一种不含任何添加剂脊悔的矿物油。这种油虽己列入分类之中，但在液压系统中己不使用。

　　2、HL液压油:HL液压油是由精制深度较高的中性基础油，加抗氧和防锈添加剂制成的。HL液压油按40℃运动粘度可分为15、22、32、46、68、100六个牌号。Abstract: hydraulic oil is used in hydraulic transmission and control system to transfer energy working medium, and has lubrication, cooling and rust-proof role. Hydraulic oil has good anti-wear performance, after use to ensure long life of equipment, a total of seven models, namely HH, HL, HM, HR, HG, HV, HS, which 46,48 these two brands on behalf of the HL hydraulic oil, they compare which is better? Let's take a look at the article! 1. There are several types of hydraulic oil and there are 7 kinds of nanocracks. The hydraulic oils of HH, HL, HM, HR, HG, HV and HS in the GB/T7631.2-2003 classification are all mineral oil hydraulic oils. 46,48 these two brands represent HL hydraulic oil. HH hydraulic oil: HH hydraulic oil is a mineral oil without any additives. Although this oil has been classified, it is not used in hydraulic systems. 2. HL hydraulic oil: HL hydraulic oil is made from highly refined neutral base oil with antioxidant and antirust additives. HL hydraulic oil can be divided into 15,22,32,46,68,100 grades according to 40 ° C kinematic viscosity.
