泵送煤水两相流时泥浆泵的性能及通气的影响

摘要

Performance change of head, efficiency, power and cavitation about slurry pump are studied when handling coal-water two-phase flow with varied concentration and size. Also the effect of entrained air is surveyed. Theoretical analysis of results has been conducted, all those will provied beneficial reference for pump using and developing in the fields such as mineral processing.%研究了泥浆泵泵送不同浓度与粒度的煤水两相流时扬程、效率以及功率与汽蚀性能的变化，并考虑了通气对泵性能的影响。还对试验结果进行了理论分析，可以为选矿等行业离心泵的使用与开发提供有益的参考。
