  　　柱塞阀漏油主要有以下原因：(1)主轴油封损坏或轴有缺陷、划痕;(2)内部泄漏过大，造成油封处压力增大，而将油封损伤或冲出;(3)泄油管过细过长，使密封处漏油;(4)阀的外接油管松动，管接头损伤，密封垫老化或产生裂纹;(5)变量调节机构螺栓松动，密封破损;(6)铸铁阀壳有砂眼或焊接不良。 　　现在生产柱塞阀的厂家很多，进口件和国产件结构不尽相同，每一台阀都应严格按照其出厂使用说明书使用。在维修阀时，首先应该检查阀在系统中的安装、使用是否得当，便于及时查出损坏原因，消除隐患，保证系统正常工作。已修复的液压阀应通过一定的检测设备检测后才能使用。如不具备检测条件，也应在系统中反复调试，使其能正常工作。
