通过测量在不同空气/水流量、不同安装角度下,插孔式分配器各出口液相流体的流量,得到两相流体流量、安装角度对分流器性能的影响。由实验结果可得:当两相流体流量增加时,插孔式分流器的性能变好;当插孔式分配垂直安装时,分流性能最好;当倾斜安装时,分流性能变差。当倾斜角度在0?~30?时,随着倾斜角度的增加,不均匀度平缓增加;当倾斜角度在30?~90?时,随着倾斜角度的增加,不均匀度增大的速率变大。

The liquid flow rate of each outlet of jack-type distributor is measured under test conditions of different air/water flow rates and different installation angles to know the influence of two-phase flow rate and installation angle on the performance of distributor. From the experimental results, it can be known that, the performance becomes better as the two-phase flow rate increases; the performance gets the best when it is vertically installed; the performance gets worse when it is inclined installed. When the installation angle is between 0°~30°, the unevenness increases gradually as installation angle increases; while when the installation angle is between 30°~90°, the increase rate of unevenness becomes bigger as installation angle increases.
