摘要： A sealing mechanism for a fluid pump comprises first and second seal members which are coaxially and radially oriented relative to each other, and are positioned between the rotating and non-rotating elements of the fluid pump to maintain a competent seal which is simple to assembly, maintain and repair or replace, and which also improves pump operation when compared to known sealing mechanisms for fluid pumps.
摘要翻译：用于流体泵的密封机构包括第一和第二密封构件，该第一和第二密封构件相对于彼此同轴且径向定向，并且位于流体泵的旋转和非旋转元件之间，以保持易于组装的主管密封件，维护和修理或更换，并且与已知的流体泵密封机构相比，还可改善泵的运行。

摘要： A precast prerotation basin system (10) for use in a wet well for removing water or fluid therefrom is disclosed which comprises a prefabricated, three-dimensional body having a prerotation basin (16) and fluid entrance channel (34). The precast prerotation basin (16) presents an improvement over prior means of forming prerotation basins downhole in a wet well because the basin system of the present invention is prefabricated, easily transportable and can be placed in a wet well without the need for providing a cement casing or floor beforehand. The precast prerotation basin of the present invention is pre-structured for accurate alignment of a centrifugal pump (44) therein and eliminates the cost and inaccuracies of forming prerotation basins from molding cement downhole.
摘要翻译：公开了一种用于湿井中用于从其中除去水或流体的预制预旋转盆系统（10），其包括具有预旋转盆（16）和流体入口通道（34）的预制的三维体。由于本发明的盆地系统是预制的，易于运输的并且可以放置在湿井中，而不需要提供水泥，所以预制预旋盆（16）比在湿井中井下形成预旋转盆地的先前方法提供了改进。预先套管或地板。本发明的预制预旋转盆预先构造成用于在其中精确对准离心泵（44），并且消除了从模拟水泥井下形成预旋转盆的成本和不准确性。

摘要： A pitot tube inlet (40) for the pitot tube (26) of a centrifugal pump is configured to improve pump efficiencies when processing fluids that have solids content wherein the type or character of which causes the solids to accumulate along the inner peripheral surface of the rotor (14) of the pump. The pitot tube inlet is configured to contact and remove the accumulated solids from the rotor to lessen the drag on the rotor, to lessen degradation of the pitot tube and to improve pump efficiencies.
摘要翻译：用于离心泵的皮托管（26）的皮托管入口（40）被配置为当处理具有固体含量的流体时提高泵效率，其中其类型或特征导致固体沿着内部表面累积泵的转子（14）。皮托管入口构造成接触和去除转子上积聚的固体，以减少转子上的阻力，减少皮托管的退化并提高泵效率。
