DRE6X-1X/75MG24-8NZ4M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。 主营： VICKERS美国伊顿威格士/BOSCH-REXROTH德国博世-力士乐/PARKER美国派克/美国ASCO/ATOS意大利阿托斯等著名欧美液压品牌的液压元件，电液换向阀，平衡阀，调速阀，溢流阀，减压阀，顺序阀，电磁阀，叠加阀，比例阀，单向阀，手动阀，节流阀，伺服阀，柱塞泵，叶片泵，压力开关继电器，马达，放大器等系列机电设备产品，部分产品库存有现货，货期优势供应。
