    • PURPOSE: A pump inducer is provided to prevent pressure loss, reduction of efficiency and corrosion by intercepting bubbles generated as static pressure locally descends under vapor pressure of fluid. CONSTITUTION: An inducer includes sweeps(S) swinging from an entry in rotating direction to reduce influence of turbulence on tips of blades; and a passage(P) expanded to have enough increase of pressure to burst generated bubbles therein. Sweep angles(Theta, Theta_0) of the sweeps are changed from a hub(R_hub) to the tips(R_tip) by an equation R(Theta) = R_tip - (R_tip - R_hub) x (exp(Ln2((Theta¬2)/(Theta_0¬2))) - 1).
    • 目的:提供泵诱导器,以防止压力损失,通过拦截在静压在流体的蒸气压下局部下降时产生的气泡而降低效率和腐蚀。 组成:诱导器包括从旋转方向的入口摆动的扫掠(S)以减少湍流对叶片尖端的影响; 和通道(P)膨胀以具有足够的压力增加以破裂其中的气泡。 通过等式R(θ)= R_tip - (R_tip_R_hub)x(exp(Ln2((θ2)),将扫描的扫描角度(Theta,Theta_0)从轮毂(R_hub) /(Theta_0¬ 2))) - 1)。
