摘要： A safety device (34) for use in a suction outlet assembly (10) of a swimming pool (12), whirlpool, spa or the like is disclosed. More particularly, the outlet assembly has an opening (22) therein in communication with a pump (24) adapted to create sufficient suction for causing fluid flow through the outlet assembly and a cover (30) mounted over the opening without substantially obstructing fluid flow therethrough. The safety device includes an obstructing mechanism (38) for obstructing the opening when the cover is not properly positioned or affixed to the outlet assembly, whereby fluid flow through the outlet assembly is substantially prevented even if the pump is in operation.
摘要翻译：公开了一种用于游泳池（12）的抽吸出口组件（10），漩涡，温泉等的安全装置（34）。更具体地，出口组件具有与泵（24）连通的开口（22），泵（24）适于产生足够的吸力以使流体流过出口组件;以及盖（30），其安装在开口上方，而基本上不阻碍流过其中的流体。安全装置包括阻挡机构（38），用于当盖未正确定位或固定到出口组件时阻挡开口，由此即使泵处于运行状态，基本上防止流过出口组件的流体流动。

摘要： Apparatus (10) for pumping fluids includes a housing (14) having a pump chamber (56) therein. The pump chamber (56) has an opening formed in one end (22) of the housing (14). An impeller (120) is rotatably mounted in the pump chamber (56), while a diffuser (94) is mounted in the pump chamber (56) through the opening of the housing (14) and has a portion (112) which radially surrounds the impeller (120). The apparatus (110) also includes a forming structure (128), mounted in the pump chamber (56) through the opening, for forming a volute chamber (134) in the pump chamber (56). The impeller (120) and the diffuser (94) are removably mounted in the volute chamber (134). The diffuser (94) and the forming structure (128) are discrete from one another and removably mounted in the pump chamber (56) such that the diffuser (94) and the forming structure (128) are independently and selectively replaceable.
摘要翻译：用于泵送流体的装置（10）包括其中具有泵室（56）的壳体（14）。泵室（56）具有形成在壳体（14）的一端（22）中的开口。叶轮（120）可旋转地安装在泵室（56）中，而扩散器（94）通过壳体（14）的开口安装在泵室（56）中，并具有径向包围的部分（112）叶轮（120）。装置（110）还包括通过开口安装在泵室（56）中的成形结构（128），用于在泵室（56）中形成蜗壳室（134）。叶轮（120）和扩散器（94）可拆卸地安装在蜗壳室（134）中。扩散器（94）和成形结构（128）彼此离散并且可拆卸地安装在泵室（56）中，使得扩散器（94）和成形结构（128）可独立且可选择地更换。
