11 蒸汽喷射泵抽不下去负压
Reply #52019-02-07
我们这边的三级蒸汽喷射泵,全部开起来负压抽不下去,并且一级的蒸汽会倒流进塔的回流罐里,求助海友们这是什么情况,蒸汽规格1.1MPa,温度190度,喷射泵已经拆检,没发现什么异常,求助求助

目前有 e个塔出现这种情况,着急啊,喷射泵时杭州杭真的
Reply #72019-02-07
还望海友们不吝赐教,谢谢

投用前精馏塔已经做过 e.1MPa气密实验,保压合格,空塔时塔压也抽到到设计值5KPa,进物料后不行了

本帖最后由 3K83657PPZ 于 2Z7Z- 113:K8 编辑 是不是进料速度过快或者排出口堵塞造成的
Reply #112019-02-08
排出口已经确定没有堵塞,塔里进完料了已经,还没开始持续进料,塔釜也没有蒸汽,负压也抽不下来
Reply #122019-02-08
能否个详细的喷射泵结构图就好分析了
Reply #132019-02-10
原因找到了没?学*一下 “一级的蒸汽会倒流进塔的回流罐里”个人感觉出口有问题吧
Reply #142019-02-11
现在在等喷射泵厂家过来
Reply #152019-02-11
你拆开看,检查喷射头是否破损,如果破损会严重影响抽真空质量的
Reply #162019-02-18
已经拆了,没啥问题,但是喷射头比较短,不知这个有没有影响
