根据吨位对液压机进行分类，其中500吨液压机在很多行业中有所涉及，比如翻边、校正等工艺都会用到它20吨单柱液压机。在液压机内部有一个关键性的部分滤油器单柱液压机，它的作用是在油液正式进入油泵之前将杂质过滤出去，以防杂质堵塞管道和油泵，那么，需要定期维护这部分的原因是什么？

滤油器虽然是不起晚的小部件，却在整个系统中起着重要作用，当油液从油缸中进入油泵的时候，会优先通过滤油器。如果滤油器发生堵塞，则进入油泵的油液含量少，会导致油泵的空转，空气对泵会产生较大的摩擦力拉伸液压机，时间一长，不仅会使局部过热，还会损坏油泵。如果滤油器的滤过效果减弱，有大部分杂质进入油泵，也会增加油液的粘度，影响整个机器的工作效率。长时间的杂质堆积，也会对一些部分产生腐蚀和损坏，所以应定期检查和及时更换滤油器上的滤膜框架式液压机。
