摘要
对日产 60 0 t合成氨厂冷氨泵在运行中发生损坏的原因进行了分析 ,其主要原因是泵的机械密封“O”型环损坏 ,泵在运行中发生汽蚀现象 ,泵体结构有缺陷。在分析上述原因的基础上 ,提出了几项改进措施 。
With the analysis on the damage of the cold ammonia pump during run in a synthetic ammonia plant with a production of 600t ammonia per day, it is found that the causes to the damage are the break of pump mechanical 'O' ring seal, eclinse of pump by vapour, defects in its structure. On the base of the reasons, several measures to promote its property are put forward to avoid more damages of the cold ammonia pump.
