    摘要： A centrifugal compressor, including: a housing, the housing including: an inlet, a flow channel, an impeller outlet, and an air diffusing channel; a centrifugal impeller disposed inside the housing; a rotating wall, the rotating wall including a front cascade; and a rotating disc, the rotating disc including a rear cascade. The impeller outlet is disposed adjacent to a rear part of the centrifugal impeller and is connected to the flow channel via the air diffusing channel. The rotating wall is disposed between the centrifugal impeller and the housing. The front cascade is disposed inside the front part of the rotating wall and is connected to a dynamic driving device. The rotating disc is disposed inside the housing adjacent to the air diffusing channel and is in a rigid connection with the rotating wall.

    摘要： A fan comprises a hub, fan blades, and inserts. The hub comprises outwardly extending mounting tabs that lie along a common horizontal plane. The fan blades are hollow, such that each mounting tab is inserted in the hollow interior of a corresponding fan blade. Each insert is positioned in the hollow interior of each fan blade, between each mounting tab of the hub and the interior surface of the corresponding fan blade. Each insert is configured to position and maintain the chord line of each corresponding fan blade at an oblique angle relative to the horizontal plane of the hub. A kit may include several insert sets to choose from to provide adjustable angle of attack. A fan control system includes a dimmer switch and a control module, which allows the dimmer switch to be used to infinitely adjust the speed of a fan motor within a range.

    摘要翻译： 风扇包括轮毂，风扇叶片和插入件。 轮毂包括沿着共同的水平面布置的向外延伸的安装翼片。 风扇叶片是中空的，使得每个安装翼片插入相应风扇叶片的中空内部。 每个插入件位于每个风扇叶片的中空内部，在轮毂的每个安装翼片和相应的风扇叶片的内表面之间。 每个插入件构造成相对于轮毂的水平面以相对于倾斜角定位和维持每个对应的风扇叶片的弦线。 套件可以包括几个插入组，以提供可调节的迎角。 风扇控制系统包括调光开关和控制模块，其允许调光开关在一定范围内无级调节风扇电动机的速度。
