部分流式切线泵在高效率条件下扬程系数的确定

Determination of Head Coefficient for Part FlowTangent Pumps with High Effciency

本文从理论和实例出发,分析了在不降低效率的前提下,提高泵扬程系数的条件。指出切线泵的扬程系数与叶片数、喉部面积、集液器断面积的关系。

Based on the theory and the experience, the requirements for increasing the head coefficient under the condition of maintaining the efficiency were proposed in this paper. At the same times, the relationships of the head coefficient with the number of the blade, the throat area and the sectional area of the collector were analyzed.
