| 摘 要： | 从降低除氧器设置高度和适应除氧器滑压运行出发,提出装置带有诱导轮的变速给水泵,以利降低泵组的必需汽蚀余量。经六个不同设计参量的诱导轮与100D16型多级离心泵的配合试验,结果表明:其中最佳的配合可使泵组必需汽蚀余量仅为原泵的1/5,效率较原泵提高6%,适应运行范围扩大了24.6%。

| Abstract: | In an effort to adapt a deaerator for slidiog-pressure operation and cut down its installation height, this paper proposes the use of a variable speed feedwater pnmp with aninducer being installed ahead of the main impeller to reduce the requi site NPSH of the pump set. A total of six inducers each placed in front of a 100D16 type centrifugal impeller have been tested. The measured results of such performance for one optimnm design inducer demonstrate that the requisite NPSH of the pump set can be reduced to one fifth of that of a centrifual pump without an inducer with its efficiency being increased by 6% and the rauge of variable speed operation expanded by 24.6%. |
