机械密封冷却
Reply #62018-11-27
* 2. 离心泵机械密封冷却的条件?冷却水量有什么要求吗?可以不用冷却水冷却吗?泵介质温度多少可以不用冷却水冷却?

* 3. 应该发个片子,看看长相,分分类型。 建议,若是非设计者,最好根据要求,严格执行本岗位的操作规范最好。 问题1、机封冷却的条件,就是要遵照相关材质要求满足就是了,不具备条件范围是要被损毁的。最基本的条件应该是一定温度下的不含杂质的洁净液体; 问题2、冷却水量只是将其摩擦产生的热带走就是了,这个水量有可能是设置在密封气的一侧或者是个隔离腔中,不需要人为控制流量,只要保证其压力就可以了。这个只对污水泵渣浆泵,及其他特殊要求的设备。 问题3、介质温度与这个冷却水的关系是,若这个介质温度在不使机封橡胶变形损坏、洁净、不含有杂质,对机封不产生破坏的,就不用设置冷却水冷却。
