　　46号抗磨液压油选择原则:

　　1、一般对于室内固定设备，液压系统压力＜7.0MPa、温度50℃以下选用HL油；系统压力7.0-14.0Mpa、温度50℃以下选HL或HM油，温度在50—80℃选HM；系统压力＞14.0MPa选HM或高压抗磨液压油。

　　2、对于露天寒区或严寒区选HV或HS油。

　　3、对于高温热源附近设备，选抗燃液压油。

　　4、对月环保要求较高的设备（如食品机械、医药机械），选环境可接受液压油。

　　5、对于要求使用周期长、环境条件恶劣的液压油设备选用液压油优等品；对于要求使用周期短、工况缓和的液压设备选用液压油一等品。

　　6、液压及导轨润滑共用一个系统，应选用液压导轨油。

　　7使用电液脉冲马达的开环数控机床选用数控机床液压油，使用电液伺服机构的闭环系统，选用清净液压油。

　　8、含银部件的液压系统，选用抗银液压油。46 anti-wear hydraulic oil selection principles: 1, general for indoor fixed equipment, hydraulic system pressure < 7.0 mpa, temperature 50 ° C below the choice of HL Oil; HL or HM oil is selected under system pressure of 7.0-14.0 mpa and temperature of 50 ° C and temperature of 50-80 ° C respectively, and HM or high pressure antiwear hydraulic oil is selected under system pressure of > 14.0 mpa. 2. HV or HS oil is selected for open-air cold area or severe cold area. For the equipment near the high temperature heat source, choose the fire-resistant hydraulic oil. 4. For the equipment with high requirements of monthly environmental protection (such as food machinery, medical machinery) , choose the environment can accept hydraulic oil. 5. For the hydraulic oil equipment with long service life and bad environmental conditions,
