    • A water-testing apparatus (50) tests an article such as a turbine airfoil component (20) having at least two water flow passage article inlets (30, 38, 44). The apparatus (50) includes an apparatus body (52) having a water inlet (54), and an attachment head (56) integral with the apparatus body (52). The attachment head (56) includes a holder (72) that receives the article therein in sealing contact with an article seal (58), and at least two ports, each port being in registry with at least one of the at least two water flow passage article inlets. A water flow controller (88) within the apparatus body (52) has a controller inlet (90) in water-flow communication with the water inlet (54), at least two controller outlets, each controller outlet being in water-flow communication with one of the ports of the attachment head (56), and a flow-control valve (94) disposed in a water flow path between the controller inlet (90) and the controller outlets. The flow-control valve (94) is controllable to controllably connect a single one of the controller outlets at a time to the controller inlet (90).
    • 水测试装置(50)测试具有至少两个水流通道物品入口(30,38,44)的涡轮机翼部件(20)的物品。 设备(50)包括具有进水口(54)的装置主体(52)和与设备主体(52)成一体的附接头部。 附件头部(56)包括一个保持器(72),该保持器(72)在其中接收与物品密封件(58)密封接触的物品,以及至少两个端口,每个端口与至少两个水流中的至少一个对准 通道文章入口。 设备主体(52)内的水流控制器(88)具有与入水口(54)水流连通的控制器入口(90),至少两个控制器出口,每个控制器出口与 安装头(56)的一个端口和设置在控制器入口(90)和控制器出口之间的水流路径中的流量控制阀(94)。 流量控制阀(94)是可控的,以一次一个地控制地将控制器出口中的一个控制器连接到控制器入口(90)。
