高速泵启动时需要稍开出口阀,为什么启动时需要开开出口阀?不太理解,请大家说说加分
Reply #42019-09-13
否则你出口阀会很难打开,前后压差太大了。。。。。
Reply #52019-09-13
高速泵出口压力通常比较高,你开起来后出口阀门很难打开。如果长时间打不开出口阀门会会造成机泵气蚀,损坏机泵。

高速泵的出口压力一般在多少
Reply #72019-09-14
一般高速泵的出口压力最低多少
Reply #82019-09-14
出口压力和泵有关系,做化工的不能用一些诸如大概、可能、估计类似模棱两可的词语

来出来解决问题,对于各种高速泵一一分析吧,不同的泵出口开度确定确定值是多少。照这么说,没有数据不算解决问题。那这个问题留给你来回答。先给我们列出一台高速泵,给出关键的泵参数,对应出口开度多少?

那. 同意楼上几位的看法,流量高扬程就是高速泵的典型特点。除了楼上大神说的意见外,另外由于高速旋转,若启动后再去调节阀门,开得慢或开不出,会使输送介质在里面来回搅拌、温度会很快升高。此时介质极易汽化,造成气蚀,极易造成泵损坏
