包括变速马达的多级压缩系统
摘要：
多级流体压缩系统包括带有第一入口和第一出口的第一离心式压缩机级以及带有第二入口和第二出口的第二离心式压缩机级。第二入口接收来自第一出口的压缩流体流。第一变速马达联接到第一离心式压缩机级，并可操作以便以第一速度驱动第一离心式压缩机级。第二变速马达联接到第二离心式压缩机级，并可操作以便以第二速度驱动第二离心式压缩机级。第一速度和第二速度是各自独立的变量。
摘要（英）：

A multi-stage fluid compression system includes a first centrifugal compressor stage having a first inlet and a first outlet and a second centrifugal compressor stage having a second inlet and a second outlet. The second inlet receives a flow of compressed fluid from the first outlet. A first variable-speed motor is coupled to the first centrifugal compressor stage and is operable to drive the first centrifugal compressor stage at a first speed. A second variable speed motor is coupled to the second centrifugal compressor stage and is operable to drive the second centrifugal compressor stage at a second speed. The first speed and the second speed are each independently variable.
