(1)在设计和加工环节中要充分考虑影响泄漏的重要因素密封沟槽的设计和加工。美国汽车行业工程师协会(SAE)推荐以下两种防止油口漏油的解决办法。①SAE直螺纹“O”形圈油口：密封靠“O”形圈，连接靠直螺纹;②SAE4螺栓法兰：适用于较大油口。另外，密封件的选择也是非常重要的，密封表面的粗糙度通常静密封表为Ra3.2～Ra1.6，动密封表面为Ra0.8～Ra0.4。如果不在初全面考虑泄漏的影响因素，将会给以后的生产中带来无法估量的损失。
(2)在液压油的污染控制上，要从污染的源头入手，加强污染源的控制，还要采取有效的过滤措施和定期的油液质量检查。为有效地切断外界因素(水、尘埃、颗粒等)对液压油缸的污染，可加一些防护措施等。力士乐 比例阀 武汉
(3)装配方面。液压系统装配前，应检验元件的耐压性能，检查元件各结合面有无外渗漏现象，若出现渗漏，则应采取相应措施。只有当所有元件不漏不渗后才可正式装进系统使用。液压元件和液压系统在进行装配时，要进行严格清洗，去毛刺、除焊渣，并进行必要的防锈蚀处理，严格按照装配工艺要求进行装配，杜绝因装配引起的间隙畸变和毛刺、焊渣及锈蚀物等形成的间隙磨料。
(4)减小液压冲击。常用的方法有：①尽量降低系统的启动、停止和换向频率;②对于需要频繁换向的液压系统，尽可能用带阻尼器的换向阀;③在控制阀的前面设置蓄能器，减小冲击波传播的距离，从而减缓液压冲击;④加大管道通径，尽量缩短管道长度或采用橡胶软管;⑤设置安全阀，系统压力增大时，可起卸荷作用降低压力冲击。(5)机械在磨合期容易出现渗漏现象，这是由于部分铸造、加工等缺陷在装配调试时难于发现，但由于作业过程中的振动、冲击作用，这种缺陷就被暴露出来，故应注意磨合期的渗漏情况，作到及早发现、及时处理。
