摘要
离心轮水力性能的优劣对泵的效率影响最大,离心轮加工质量好坏直接影响泵的特性。针对钎焊式离心轮加工的技术要求与技术难点进行分析、研究,结合现有数控设备对离心轮的加工工艺进行改进、优化及数控加工转化。
The hydraulic performance of the centrifugal impeller greatly influences pump efficiency, thus the machining quality of the centrifugal impeller directly influences pump properties. Based on the study of technological requirements and difficulties of the brazed centrifugal impeller machining, the process optimization and NC machining of the centrifugal impeller were realized by utilizing the existing NC equipments.
