"我们将一台分馏塔进料泵，入口压力 035MPa，，出口 13MPa，进料温度 265℃机械密封采用plan3253B运行中机封罐压力达到 "2.1MPa运行中机封罐压力达到 2.2MPa，造成非驱动端机封损坏冲洗油用得 6℃混合柴油大家帮忙分析一下原因？

"不知道32的冲洗液是多少压力从现在看应该是由于密封柴油泄露造成密封罐的压力过高"

"出口口压力 " "3MPa" "plan32的压力也这么高53B的压力 " "2 "2建议检查一下蓄能器如果皮囊破碎或压力卸没了蓄能器里全部充满隔离液液体是不可压缩的可能会受温度影响导致压力升高"

"你冲洗液压力太高了造成反压一般隔离液压力要比冲洗油压力高 " "55-1MPa" "否则反压会造成冲洗油进入隔离液系统你冲洗液压力可能太高了看一下压力表是不是坏了"

"冲洗液压力应该比密封腔压力大 " " " "你 " " " "你冲洗液只有 " " " "泵入口压力 " " " " "出口出口压力至少也有 " " " " " " " " "冲洗液压力偏高我怀疑冲洗液并没有起到冲洗效果而是一直在密封腔里没有流动再加上高温导致气化了"

" "53B压力可以适当下调高于密封腔 " " " "这样密封的使用寿命会高一些将详细工况信息发给密封供货商他们会给出合理的压力设定"
