沿黄高扬程电力提灌泵站水泵焊接式叶轮试验研究

摘要

本文为逐步解决沿黄地区大中型高扬程电力提水泵站以24SH-19型单级双吸式离心泵为重点对象，研究其叶轮焊接工艺可行性来解决影响着水泵的扬程、出水量、效率、抗汽蚀与抗磨性等问题所做的一项试验研究。%In order to overcome the defect of the impeller of large and medium-sized high-lift power pump, this article takes 24SH-19 single-stage double-suction centrifugal pump as the key object and studies the feasibility of its impeller welding in order to solve the problems affecting the lift, water flow, efficiency, cavitations and abrasion resistance of the pump.
