破碎锤为啥每工作500H需更换油封?

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。
