泵打压力与设备维持的压力差
Reply #62019-10-02
因为气体可压缩,压缩后气体的压力就会增加; 而液体几乎不可压缩,它的压力从哪来?

你的具体流程不详,这个原理类似于向某个压力容器注入液体,在某一压力条件下的混合物料的要求。比如空气冷却塔,就是在压力罐中注入高于气压的水,在容器内喷淋的原理。 推荐化工人员的工具书《化工原理》。

设备的压力,是由容器的气相建立的。 假如我把容器升压到3.2MPA, 泵打的流量还是可以进来, 但静压要“贴谱”3.2MPA,导致流量小一点。 液体静压不能改变气相压力, 后者由气相的组分/温度建立起来的。

压力根据需要,由整个系统用安全阀定压产生。

河底的水有没有压力呀?

楼主的基本概念不清!还需要进一步学*:P

进料口前,装物料容器的压力
Reply #132019-11-14
先用氮气升压,在用泵给设备进料。 还有一点,假设有一台泵,它的出口有两个阀,阀之间有排放。停泵之前把两个阀隔离。后停泵,你在开那个排放,你会发现排放口,物料是喷出来的。这就是液体物料有压力的表现。希望你能理解。

泵输送的压力或者是需要进料的设备存在的压力
