隔舌间隙
1.
Aim at 5 inner recirculation self-priming centrifugal pumps that specific speed are 74~112,adopt 3 different inner-diameter suction pipes and 6 kinds of separation tongue gap,a more overall experimental study on self-priming time under rule height and the max vacuum that can be attained was carry on.
针对比转速为74~112的5台内混式自吸离心泵,采用3种不同直径吸水管和6种不同隔舌间隙,对其规定高度自吸时间和极限真空度进行了较全面的试验研究,并对试验结果进行了综合分析。
3) volute tongue
蜗舌
1.
Effects of the volute tongue on noise and performance of dual fan kitchen exhaust hoods;
蜗舌对双叶轮抽油烟机噪声和性能的影响
2.
The calculations indicate that,the maximum pressure occurs near the volute tongue in the diffuser.
计算结果表明,扩压器内压力最大的位置出现在蜗舌附近;当进口无预旋或预旋不大时,叶轮内流动参数的周向分布和一周叶片的受力情况是不对称的;在进口大预旋条件下,除蜗舌附近的周向位置外,叶轮内流动参数和主叶片受力趋于周向对称分布。
3.
In orde to reveal the changing regulation of the fan characteristics under the different operating conditions, the developing laws are analyzed on the structure of volute tongue and outlet flow field It is concluded that the "throat" extruding phenomenon during the small flowrate operation the moving whirlpools at outlet field and back flowing phenomenon at volute tongue duri.
通过对离心通风机的变工况定常流动数值模拟,主要研究了蜗壳舌部及出口流场结构的演变规律,并分析了不同工况下所对应的风机特性变化实质,指出就蜗壳而言,其小流量工况时的"喉部"挤压现象、大流量时的出口流动漩涡及蜗舌回流现象,是影响风机整体特性及运行工况范围的主要因素之一;改善蜗舌及出口几何结构,可以有效提高风机的压头及运行效率。
