摘要
介绍熔融尿液泵结构特点与运行情况,针对使用过程中机械密封损坏频率较高的问题,分析原因为尿液在密封腔内置换不完全、停运后结晶所致。改进机械密封结构,在密封腔部位增加冲洗口,并改进操作。改进后熔融尿液泵运行情况良好。
The structural characteristic and operation of melted urine pump were described. Regarding to frequent failure of mechanical seal, the analysis showed that the failure was caused by incomplete purging that led to urea crystallization inside the seal chamber. The mechanical seal was modified by adding a washing nozzle at the position of the chamber. The pump run smoothly after the modification.
