["多流量 instablebilee不稳定

2020-03-18View Original

Thread Content

1我们公司有一台锅炉给水多级泵,新安装运行大概一个多月就出现流量不稳定状况。流量一直往下掉、每半个小时就得手动调整一下、不然量就达不到要求。还有一个问题就是冷却水出水温度特别高、换了新填料也就只能顶一个星期就会出现发热状况。真不知道怎么弄才好。

你手动调调哪里?这种泵机械密封要好一些。

进口流量跟不上、调节进口旁路是吧?

汽蚀?或是轴向力平衡的的不好?

填料泄漏量情况怎么样、看下、可能填料密封泄露的同时往泵内吸入空气、泵出现气蚀或抽空的情况、紧固填料压盖、或者更换填料、或者技改采用机械密封第一套密封冲洗方案。另外检查泵入口过滤器是否堵塞、检查泵入口压力、入口压力是否使泵在打高温水时出现气蚀

填料泄流量不够、或介质水结垢严重

流量慢慢往下掉、手动调节出口阀、回流阀等

入口流量绝对是够的、而且全开着。我们调节调节出口阀和回流阀

10具体参数未见。如何判断进口流量足够、3泵运行各项参数、4进出口管线状态。我们遇到类似情况、最终是有塔填料掉下、把进口过滤器堵了。

可以考虑下是否除氧器的栅板脱落、导致泵进口流量不够造成泵抽空
