    • A rotatable rotor for separating components contained in a fluid, comprising an annular base having a first annular channel and an annular cover having a second annular channel for holding a flexible doughnut-shaped centrifuge bag therebetween. The cover has one or more radially spaced apart concentric indicator lines for monitoring the separation of the components. When the base and cover are superimposed, the first and second channels define an annular interior chamber having an off-centered figure eight configuration. The base and cover each comprise a grooved column axially centered and extending from the base top surface and the cover bottom surface, respectively. The flexible bag comprises inner and outer tubes extending from the core of the bag and which are seated in the column grooves to ensure that the bag is fixably rotatable with the rotor.
    • 一种用于分离流体中包含的组分的可旋转转子,包括具有第一环形通道的环形基座和具有第二环形通道的环形盖,所述第二环形通道用于在其间保持柔性的环形离心机袋。 盖具有一个或多个径向间隔开的同心指示线,用于监测部件的分离。 当底座和盖子叠加时,第一和第二通道限定具有偏心图形八配置的环形内部腔室。 基座和盖板分别包括一个轴向对中并从底部顶表面和盖底表面延伸的开槽的柱。 柔性袋包括从袋的芯延伸并且位于柱槽中的内管和外管,以确保袋与转子可固定地旋转。

    • A liquid spray nozzle configured to provide a relatively uniform droplet size spray having a nozzle body, a flow passage disposed in the nozzle body, a turbulent flow mechanism in the flow passage, a flow separating mechanism in the flow passage and a converging mechanism at the nozzle body outlet. The turbulent flow mechanism, preferably a cylindrical pin, induces turbulent flow to the fluid stream flowing through the passage. The flow separating mechanism, also preferably a cylindrical pin, separates the turbulent flow into two separate, diverging streams. The converging mechanism is configured to direct the two streams together such that the colliding thereof produces a spray made up of substantially uniform sized droplets. Preferably, the converging mechanism is an orifice plate having two outwardly extending deflecting members and a generally oval-shaped opening and the nozzle body is adapted to threadably connect to a hose or other conduit.
    • 一种液体喷嘴,其构造成提供具有喷嘴体的相对均匀的液滴尺寸喷雾,设置在喷嘴体中的流路,流路中的湍流机构,流路中的流动分离机构和位于流路中的会聚机构 喷嘴体出口。 湍流机构,优选圆柱形销,引起湍流流动流过通道的流体流。 流动分离机构,优选圆柱形销将湍流分离成两个分开的发散流。 会聚机构构造成将两个流引导在一起,使得其碰撞产生由基本均匀的大小的液滴组成的喷雾。 优选地,会聚机构是具有两个向外延伸的偏转构件和大致椭圆形开口的孔板,并且喷嘴本体适于与软管或其它导管螺纹连接。
