摘要： A high-speed blower designed to move and circulate dry process gas includes an axial or mixed-flow compressor driven by a brushless permanent magnet synchronous motor utilizing a remotely mounted variable frequency drive. The blower uses foil gas bearings which enable high-speed, low-power loss, and oil-free operation. The blower comprises an outer blower housing and an inner blower housing defining an annular cavity therebetween. A cooling flow of process gas may be leaked through the inner blower housing to cool the internal operational components of the blower, including the motor and the bearings, and to capture heat therefrom, which can be added to the process gas flow moving through the blower. Diffuser vanes and flow-straightening vanes are provided on the outer surface of the inner blower housing to improve the fluid dynamics of the process gas flow through the blower and heat transfer from the inner blower housing.
摘要翻译：设计用于移动和循环干法气体的高速鼓风机包括由使用远程安装的变频驱动器的无刷永磁同步电动机驱动的轴流式或混流式压缩机。鼓风机采用铝箔气体轴承，可实现高速，低功耗和无油运行。鼓风机包括外部鼓风机壳体和在其间限定环形空腔的内部鼓风机壳体。处理气体的冷却流可以通过内部鼓风机壳体泄漏，以冷却包括电动机和轴承在内的鼓风机的内部操作部件，并从中吸收热量，这可以被添加到通过鼓风机移动的工艺气体流。扩散器叶片和流动整流叶片设置在内部鼓风机壳体的外表面上，以改善流经鼓风机的工艺气体流动的流体动力学和来自内部鼓风机壳体的热传递。
