耐腐蚀磁力泵退磁的原因及解决方法

文章出处:http://myart51.com/ 人气:发表时间:2018-10-30

    由于耐腐蚀磁力泵的滑动轴承是以所输送的介质进行润滑冷却的,因此运转时,润滑流道必须提供足够流量的介质对内磁转子与隔离套之间的环隙区域和滑动轴承与推力盘、转轴之间的摩擦副进行润滑冷却。而生产厂家只在一对滑动轴承之间即泵轴的中间部位开一个回流孔,而且轴和回流孔都不是通孔,这样将使通过摩擦副的冷却润滑介质流量不够,产生的热量不能及时带走,不能建立并保持良好的液体摩擦状态。自润滑冷却不好造成滑动轴承干摩擦导致抱轴,而外磁转子继续旋转产生热量。在内磁转子工作极限温度以下(钕铁硼为120℃),其传递能力的下降是可逆的,而在极限温度以上则是不可逆的。即内磁转子冷却后,丧失的传递能力再也不能恢复,使内磁转子逐步失去磁性,导致内磁转子出现高温退磁。
