液压油是液压系统传递动力的介质,同时又是系统的润滑剂与冷却剂。它对于提高液压系统的可靠性、延长液压元件的使用寿命及节省资源、节省能源等方面都有直接的影响,近年来我国已试成投产了多种专用液压油,以供液压设备在各种工况下使用。但是,如果对液压油选择不当、使用不慎、更换不及时,则会导致液压油过早地污染变质,加速液压元件的损坏,严重影响液压设备的正常运转和效率,甚至造成重大事 Hydraulic fluid is the hydraulic system power transmission medium, but also the system of lubricants and coolant. It has a direct impact on improving the reliability of the hydraulic system, extending the service life of hydraulic components and saving resources and saving energy. In recent years, China has put into trial production of a variety of special hydraulic oil for hydraulic equipment in a variety of Working conditions. However, if the improper selection of hydraulic oil, the use of careless, replacement is not timely, it will lead to premature pollution and deterioration of hydraulic oil to speed up the hydraulic components of the damage, seriously affecting the normal operation of hydraulic equipment and efficiency, and even cause major events
