摘　　要：离心泵采用变频驱动的目的就是在化工工艺要求不断变化的复杂情况下改变输出,在一些特定场合,如锅炉给水、罐区供料装车等,操作工况比较复杂,考虑到建设投资与运行维护要求,变频泵通常会单独或者与工频泵并联使用,因此有必要对变频离心泵的所有相关特性进行深入探讨。The purpose of variable frequency drive for centrifugal pumps is to change the output under the complicated conditions of changing chemical process requirements.In some specific occasions,such as boiler feed water,tank area feeding and loading,etc.,the operating conditions are more complicated,considering construction investment In connection with operation and maintenance requirements,variable frequency pumps are usually used alone or in parallel with industrial frequency pumps,so it is necessary to thoroughly explore all relevant characteristics of variable frequency centrifugal pumps.
