- 摘要:
- 目前平板螺旋式诱导轮的扬程计算法大都没有考虑诱导轮出口涡流区的影响,计算出的扬程和实际扬程有较大的偏差,涡流区的存在一方面会减小主流过流面积,使液流出口速度增大,损失增加,另一方面涡流运动自身也会消耗能量,使得诱导轮的扬程有所降低。以径向平衡理论为基础,考虑诱导轮出口涡流区的影响,提出一种扬程的修正计算法,用该方法对两种诱导轮进行了计算,计算结果和试验实测值比较接近,可以更准确的计算非空化工况下诱导轮的扬程。
- Abstract:
- Since the current methods of calculating the head for flat-plate helical inducer do not consider the influence of the vortex region at the inducer outlet, there is large deviation between the calculated head and the actual head. On the one hand, the vortex region reduces the area of the main flow, which makes the flow velocity at the outlet increased and finally makes the energy loss enhanced. On the other hand, the vortex itself expends the energy, which makes the head of the inducer reduced. Based on radial equilibrium theory, a correction calculation method for the head of the inducer is proposed in consideration of the effects of the vortex region at the inducer outlet. The head of two types of inducers was calculated with this method. The calculated results approach to the measured results in the experiment. It indicates that the new method can more accurately calculate the head of the inducer under the condition of non-cavitation.
