(3)元件制造装配精度超差：所有的液压元件及密封部件都有严格的尺寸公差、形位公差等要求。如果在制造过程中超差，例如：油缸的活塞半径、密封槽深度或宽度、装密封圈的孔和尺寸超差或因加工问题而造成失圆、本身有毛刺或洼点、镀层脱落等，密封件就会有变形、划伤、压死或压不实等现象发生，使其失去密封功能，将使零件本身具有先天性的渗漏点，在装配后或使用过程中发生渗漏。系统装配粗糙，缺乏减振、隔振措施;系统超压使用，未做到按规定对系统适时检查及易损件寿命到期但未及时更换等都会造成系统泄漏。
(4)油液温升过高：液压系统工作时，要控制油液温度，温度过高，会产生以下现象：①多数情况下，当油温经常超过60℃时，油液黏度大大下降，不仅使润滑油膜变薄，摩擦力加大，磨损加剧，而且密封圈膨胀、老化、失效，结果导致液压系统产生泄漏。据研究表明，油温每升高10℃则密封件的寿命就会减半。②油液温度升高后，体积膨胀，压力升高，而泄漏随压力的升高而加大，从而使泄漏增加。③油温升高使间隙胀缩变化。一般配合零件材质不同，材料热膨胀系数不同，当油温升高时，配合零件因胀缩变化不同，会使配合间隙发生变化，当间隙变大时，造成泄漏增加。
(5)液压系统压力冲击：液压系统中由于频繁换向，在较高压力下突然启动油泵或关闭阀门及缸体快速动作都会造成瞬时峰值压力高达工作压力的好几倍，有时足以使密封装置、管道或其它液压元件损坏而造成泄露。

造成工程机械液压系统的泄漏的因素是多方面综合影响的结果，以现有的技术和材料，要想从根本上消除液压系统的泄漏是很难做到的。只有从以上影响液压系统泄漏因素出发，采取合理的措施尽量减少液压系统泄漏。
