慈溪市浒山街道壳牌液压油-导轨油经销拉32号液压油防冻零下20度左右，液压油由深度精制的石油润滑油基础油或合成润滑油加入抗磨和抗氧剂等调制而成，它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。

　　通常对液压油的质量要求有如下几点:

　　1、适宜的粘度及良好的粘温性能，以确保在工作温度发生变化的条件下能准确、灵敏地传递动力，并能保证液压元件的正常润滑；

　　2、具有良好的防锈性及抗氧化安定性，在高温高压条件下不易氧化变质，使用寿命长；

　　3、具有良好的抗泡沫性，使油品在受机械不断搅拌的工作条件下，产生的泡沫易于消失以使动力传递稳定，避免液压油的加速氧化。The following points are generally required for the quality of hydraulic oil: 1, the appropriate viscosity and good viscosity-temperature performance, to ensure that in the operating temperature change conditions can accurately and sensitively transfer power, and can ensure the normal lubrication of hydraulic components, 2, has good rust resistance and anti-oxidation stability, in high temperature and high pressure conditions are not easy to oxidation deterioration, long service life, 3, has good anti-foam, under the working condition of continuous mechanical agitation, the foam is easy to disappear so as to make the power transmission stable and avoid the accelerated oxidation of hydraulic oil.
