随着液压装置向高性能化发展,对其所使用的液压油提出了更苛刻的要求。中高压、高压和超高压(压力分级范围见表1)的液压设备已在我国一些工业部门得到普遍的使用。但所选用的液压油却很混乱,90％以上使用机械油,其余的使用普通液压油、汽轮机油、柴油机油和进口液压油等。由于选用油不当造成液压元件早期磨损,工作不正常、出故障以致于损坏。同时,由于油的本身性质不适应高压高速下的苛
With the development of high performance hydraulic devices, the hydraulic fluid used by them poses more stringent requirements. The hydraulic equipment of medium-high pressure, high pressure and extra-high pressure (pressure grading range see Table 1) has been widely used in some industrial departments of our country. But the choice of hydraulic oil is very confusing, more than 90% of the use of mechanical oil, the rest of the use of ordinary hydraulic oil, turbine oil, diesel oil and imported hydraulic oil. As a result of improper selection of oil caused by early wear and tear of hydraulic components, work is not normal, failure to damage. At the same time, due to the nature of the oil does not meet the harsh high-pressure high-speed
