尿素熔融泵轴封泄漏原因分析与改造

Cause analysis and reform on leakage of urea melt pump gland

尿素熔融泵在使用过程中,机械密封经常泄漏,频繁检修严重影响了尿素产品的质量及生产稳定,对该泵轴封故障的原因进行分析并改造,采用与输送介质相适应的密封性能良好的机械密封,较完满的解决了轴封泄漏问题。

The mechanical seal of urea melt pump was often leaked in using process;frequent service would impact the quality of urea and production stability.As analyzing the cause of gland fault and reforming,mechanical seal with good sealing performance has been employed,which matches to pumped medium,the leakage problem has been perfectly resolved.
