["如何实现从2.5MPa减压至0.03MPa？欢迎解答。",

Reply #32019-01-08

"水井的压力为2.5MPa，水容量约为5万立方米。需要将水井的压力降至常压，同时保持流量约为1.5m³/h，且水井内的水压从2.5MPa降至常压。有什么可行的方案？",

"多级孔板有一个问题，随着压力下降，孔板的流量也下降了。有什么办法可以维持流量不变呢？",

"根据你要求的流量和压降来确定孔板数和孔径。",

"化工部的规范，要求从2.5MPa减压至0.03MPa至少需要2级级孔板"，2.5MPa减压至0.03MPa至少需要"级级孔板"，做"级级孔板"要分成4×5或3×"来实现"。每一个缓冲实现一个多级级降压目标，缓冲（多级孔板）数量×孔板（多级孔板）级数数量。",

"按照孔板减压计算有一个问题，当前端压力逐渐下降，例如降至6MPa时，原来的孔板就不能保证流量了。",
