Abstract

The effect of inside surface baffle installation conditions on the minimum impeller rotational speed for just the drawdown of floating solid was investigated. The inside surface baffle condition is the condition in which a partial baffle is placed with a clearance between the baffle and the vessel wall. In this study, a baffle with an insertion length of 0.2 times the liquid height was used. Moreover, the effect of baffle angle on was investigated. The was measured visually at least three times. The results showed that the effect of the radial installation position of the inside surface baffle on depended on the impeller position. In addition, even baffles placed parallel to the tangential flow were found to decrease .

内表面挡板条件对刚抽水叶轮转速的影响

研究了内表面挡板的安装条件对只吸取漂浮固体的最小叶轮转速的影响。内表面挡板条件是指在挡板与容器壁之间留有间隙的情况下放置部分挡板。在这项研究中，使用了插入长度为液体高度 0.2 倍的挡板。此外，还研究了挡板角度对液体高度的影响。至少目测了三次。结果表明，内表面挡板径向安装位置对叶轮位置的影响取决于叶轮位置。此外，即使是平行于切线流的挡板，也会降低......。
