工程机械液压系统油液的工作温度一般在30度到80度范围内较好,油温过高对系统会产生一系列不良影响,如粘度下降,泄漏增大,容积效率下降,造成液动速度不稳定,会造成热膨胀系数不同的运动幅之间间隙变化,甚至出现卡死等,会使油液变质,密封件老化,丧失密封性能等。 油温升高的原因多种多样,如油箱容积太小,散热面积不够,油箱储存油量太少,周围环境气温较高,冷却器作用失灵;系统中没有卸载回路,在停止工作时油泵仍在高压溢流;油管太细太长,弯曲过多,压力损失过大,元件加工精度不高,相对运动件摩擦发热过多等。
从使用维护角度来看,应注意以下几个问题:
①经常保持油箱中的正确油位,以使油液有足够的循环冷却油;
②经常保持冷却器内水量充足,管路畅通;
③在系统不工作时,油泵必须卸载;
④正确选择油液的粘度。
