破碎机在正常使用过程中，每500h必须更换油封！很多客户并不理解这样的做法，通常认为只要破碎锤不漏油，就不需要更换油封，即使服务人员多次与之沟通，任然决定周期太短，这笔费用根本就是多余的！
下面我们简单的分析一下原因（图一、图二）
红色部分：蓝色橡胶圈为"Y"型主油封，注意唇口部位朝高压油来的方向（可以参考油缸，缸头主油封的安装方法执行）
蓝色部分：防尘圈
更换原因：
1.破碎锤活塞环内的阶梯封有二条（蓝色胶圈部分），液压油全靠这两道“Y”型密封圈，阶梯封之所以能密封全靠内径上的小台阶（即唇口部分），只有1.5mm高。
2.1.5mm高度在活塞正常的情况下，也就能坚持500-800小时左右（破碎锤活塞频率相当高，以XE470标配XEB175破碎锤举例：每秒活塞运动频率为3.25-4.6次），高频的运动对油封唇口磨损非常大，一但磨平就会出现钎杆“漏油”现象；而且当该“唇口”磨平以后，活塞失去弹性支撑，稍微倾斜就会拉上活塞（轴套的磨损加剧了活塞倾斜的可能性），百分之八十的锤都是这个原因导致本体受伤的。
故障现象：
以上为500H未更换油封，导致活塞缸体等部件出现早期拉伤故障现象。（因为油封未及时更换，加上液压油清洁度不达标造成，见图三、图四、图五）如继续使用，就会造成“拉缸”的重大故障。
