轧钢厂离心水泵气蚀现象分析

The analyzing about cavitation corrosion phenomenon of the centrifugal water pump at the rolling mill

通过对负压提升式离心水泵气蚀现象的分析 ,阐述了负压提升式离心水泵产生气蚀的原因 ,说明了负压提升式离心水泵的几何安装高度与允许真空度的关系 ,用实例计算出海拔高度和水温对负压提升式离心水泵允许真空度的影响。

By analyzing about cavitation corrosion phenomenon of the nagetive pressure elevating type centrifugal water pump, it interpretcd the reasons that cause the cavitation corrosion on the nagetive pressure elevating type centrifugal water pump, specificated the relation of the mounting height site and the allowable vacuum degree, And calculated the influence that the elevation and the water temperature give the allowable vacuum degree of the nagetive pressure elevating type centrifugal water pump.
