加强设备的维护保养是确保设备正常工作十分重要的环节。目前液压传动设备经常出现四种毛病：一日“精神病”，指液压系统工作时好时坏，执行机构动作时有时无；二日“冒虚汗” ，指系统泄漏严重；三日“抖动病” ，指执行机构运动时有跳动、振动或爬行；四日“高烧病” ，指液压系统工作油液温升过高。如果对上述四种病情进行分析与诊断，寻找产生病根的原因，同时对液压设备进行科学管理，对常见故障提出预防措施，液压系统的故障就可以减少或避免。3drepe6a-2x/16eg24k31/f1m

液压设备的维护应注意下列要点：

（1） 控制油液污染，保持油液清洁，是确保液压系统正常工作的重要措施。目前由于油液污染严重，造成液压故障频繁发生。据某大型工厂统计，液压系统的故障有80%是由于油液污染引发的。油液污染还加速液压元件的磨损。

（2） 控制液压系统中工作油液的温升是减少能源消耗、提高系统效率的一个重要环节。一台机床的液压系统，若油液温度变化范围较大，其后果是：1）影响液压泵的吸油能力及容积效率。2）系统工作不正常，压力、速度不稳定，动作不可靠。3）液压元件内外泄漏增加。4）加速油液的氧化变质。

（3） 控制液压系统泄漏极为重要，因为泄漏和吸空是液压系统常见的故障。要控制泄漏，首先要提高液压元件零部件的加工精度和元件的装配质量以及管道系统的安装质量。其次是提高密封件的质量，注意密封件的安装使用与定期更换，**是加强日常维护。

（4） 防止液压系统振动与噪声。振动影响液压元件的性能，它使螺钉松动、管接头松脱，从而引起漏油，甚至使油管破裂。一旦出现螺钉断裂等故障，又会造成人身和设备事故。因此要防止和排除振动现象。线圈h507848 24vdc
