摘要： A blower unit includes an elongate main mounting member, a stator, a fan subassembly, and a blower housing. The elongate main mounting member is the main structural member of the unit. The stator includes a stator core and stator windings, and the stator is secured to the main mounting member. The fan subassembly includes a rotor and a plurality of vanes. The rotor includes a substantially cylindrical iron ring and a magnetic portion having a substantially cylindrical shape. The magnetic portion is secured within the inner diameter of the iron ring and defines a rotor bore. The stator is located in the rotor bore and is concentric with respect to the rotor. The rotor is coupled to the plurality of vanes so that the vanes rotate with the rotor. The fan subassembly also includes bearing assemblies which are spring biased towards, and into rotatable engagement with, the elongate main mounting member. The fan subassembly further includes a shroud for partially enclosing the plurality of vanes.

摘要： An assembly for producing wet compression of gas being compressed in a centrifugal-type, multistage gas compressor having an impeller, a diffuser "downstream" of the impeller, and a cross-over channel connected to the downstream end of the diffuser includes a plurality of liquid jets for injecting a vaporizable liquid such as water into a gas stream undergoing compression. The liquid jets are positioned axisymmetrically about the longitudinal axis of the compressor shaft and are adapted to inject liquid into the diffuser substantially upstream of the cross-over channel, and, in a preferred embodiment, have a radial spacing from such axis of about 1.05 to 1.1 times the maximum radius of the compressor impeller. The invention attains a marked increase in vaporization of the injected liquid, providing better compressor performance and reduced wear of compressor internal parts.
摘要翻译：一种用于在具有叶轮的离心式多级气体压缩机中进行压缩的气体的湿式压缩的组件，所述叶轮的下游扩散器和连接到所述扩散器的下游端的交叉通道包括多个用于将可蒸发的液体例如水注入到经受压缩的气流中的液体射流。液体射流围绕压缩机轴的纵向轴线对称定位，并且适于在基本上在交叉通道的上游将液体注入到扩散器中，并且在优选实施例中，具有从该轴线的径向间隔约1.05至压缩机叶轮最大半径的1.1倍。本发明实现喷射液体的汽化显着增加，提供更好的压缩机性能并降低压缩机内部部件的磨损。

摘要： Turning, or pre-swirl, vanes are housed in stationary walled annular passages located in juxtaposition with coolant gas supply slots through which coolant gas, usually air, enters the rotor structure of a rotor rim-ventilated generator. Coolant gas flow admitted through the annular passages is turned in the direction of the rotor rotation and provided with an initial tangential velocity by the turning vanes.
