兖州矿业(集团)有限责任公司开展了离心式水泵经济运行措施的研究。(1)合理选择水泵的工况点。水泵运行工况离开设计工况越远效率越低。选在最佳点运行,由于叶轮对部件磨损及管路积垢等会使工况点左移,效率将明显降低;选在右侧运行,工况点左移后反而靠近最佳工况点;(2)采用新型高效泵。一般对一级叶轮采取加宽进水口和叶片扭曲角的办法,以改善泵的汽蚀性能;(3)保持水泵高效运行的装配措施。采用符合质量标准的零
Yanzhou Mining (Group) Co., Ltd. launched a centrifugal pump economic operation of the study. (1) a reasonable choice of pump operating point. Pump operating conditions away from the design conditions the lower the efficiency. Select the best point of operation, due to the impeller wear and pipe parts on the scale will make the working point to the left, the efficiency will be significantly reduced; election in the right run, operating point left after moving closer to the best operating conditions ; (2) the use of new high-efficiency pump. General approach to the first-class impeller to widen the inlet and blade twist angle to improve the pump cavitation performance; (3) to maintain efficient pump assembly measures. Use a zero that meets quality standards
