Abstract

This research analyzes the impeller design performance that has been modified based on previous impeller designs. The previous impeller design used high engine power consumption due to the total head, so the modification of the impeller design is expected to reduce the engine power consumption. The existing design and the modified impeller design with the addition of the junction disc plate are used by this research. This research used experiment methods and theoretical methods to compare both of impeller design performances. The experiment method measures total head, fluid capacity, engine speed, and engine power consumption. The theoretical method analyzes actual fluid velocity, specific velocity, total suction head, NPSH, and pump efficiency. The results showed that the fluid flow rate was able to increase the efficiency of the centrifugal pump by 2.8%. The conclusion explains that the addition of a junction disc plate produces energy from a steady fluid flow rate to reduce the engine power consumption and escalation of pump efficiency.

加入连接盘板的离心泵叶轮设计性能研究

本研究分析了在原有叶轮设计基础上改进后的叶轮设计性能。以前的叶轮设计由于总扬程的原因，使用了高发动机功率消耗，因此叶轮设计的修改有望降低发动机功率消耗。本研究采用了现有的叶轮设计和改进后的叶轮设计，并增加了连接盘板。本研究采用实验方法和理论方法对两种叶轮的设计性能进行了比较。实验方法测量总扬程、流体容量、发动机转速和发动机功耗。理论方法分析了实际流体速度、比速度、总吸压头、NPSH和泵效率。结果表明，流体流量可使离心泵的效率提高2.8%。结论表明，增加连接盘板可以从稳定的流体流速中产生能量，从而降低发动机功率消耗并提高泵效率。
