本文系本刊今年第78期上发表之“液力循环元件性能计算的一般公式与正旋单级变扭器的性能”及“正旋多级变扭器与反旋单级变扭器的性能”两文的续篇。它论述正旋和反旋变扭器的工作轮组合怎样最合适以及当以平均流线上性能计算结果作为设计根据时,其流道宽度问题如何考虑为当这两个问题。计算结果说明:对单级变扭器而言,按泵轮→涡轮→导向器液流顺序的P—T—S型适用于正旋变扭器,按泵轮→导向器→涡轮液流顺序的P—S—T型适用于反旋变扭器。此外,关于流道宽度问题,在整个流道宽度上叶片角度若分布得不恰当时,所得到的总性能与平均流线上的性能相比要低得多,本文根据理论分析结果,计算出了整个流道宽度上的叶片角度合理的确定方法。
This article is published in the 78th issue of this issue “the general formula for the performance of the hydraulic circulation element calculation and the performance of positive rotation single-stage torque converter ” and “positive rotation multi-stage torque converter and anti-rotation single stage variable Torque performance ”two sequel articles. It discusses how best to combine rounding and anti-rotation torque converter workwheels and how to consider the problem of flow path widths when considering the average flowline performance calculation as the basis for these two problems. The calculation results show that for the single-stage converter, the P-T-S type according to the sequence of pump wheel → turbine → guide flow is applied to the positive torque converter, and the sequence of pump wheel → guider → turbine flow The P-S-T type for reverse torque converter. In addition, with respect to the width of the runner, if the blade angle is not properly distributed over the width of the runner, the resulting total performance is much lower than that of the average flow. According to the theoretical analysis, The width of the entire width of the blade angle on the determination of a reasonable way.
