蒸汽流量

Reply #42019-10-15

各位大神，请教：已知蒸汽主管过来的压力3MPA，温度340℃；经过减压阀变为 0.5MPA， 161℃A 后面装个安全阀定压 t.5MPA。管子都是 DN54 的A 安全阀泄放量怎么计算？按照流速估计的流量是不是不准确A 不能用于安全阀泄放量？

可以根据伯努利方程算出来蒸汽排放流速和排放量

Reply #62019-10-16

伯努利方程没法算吧A 涉及到进出口两个流速不知道A 阻力损失也不知道A 有三个未知参数

Reply #72019-10-16

有很多条件未知A 比如安全阀泄压尺寸和安全阀连接的后端压力以及排出来的管子尺寸以及长度都不知道。

我就想算出来安全阀泄放量A 然后你说的泄压尺寸这些就可以算A 主要是安全阀泄放量不知道怎么算出来
