    • An inlet sieve for a self-priming floating pump features a bottom wall that is carried in a position that underlies the inlet of the self-priming floating pump at a distance therebelow with the inlet of the pump aligned with an axis that passes through the bottom wall of the sieve. A perforated outer wall of the sieve stands upward from a top side of the bottom wall and extends about the axis. The bottom wall features an outer area that spans inwardly from the perforated outer wall toward the axis, and a protuberance that bulges upwardly from the outer area to an apex of the protuberance that is situated at the axis. Water flowing inwardly toward the protuberance from different radial directions is directed smoothly upward into the inlet of the pump with minimal turbulence in order to optimize the performance of the pump.
    • 用于自吸浮动泵的入口筛具有底壁,该底壁承载在自吸浮动泵的入口下方的位置,在该距离处,泵的入口与穿过底部的轴线对准 筛子的墙壁。 筛的穿孔外壁从底壁的顶侧向上竖立并围绕轴线延伸。 底壁具有从穿孔的外壁朝向轴线向内延伸的外部区域,以及从外部区域向上凸起到位于轴线处的突起的顶点的突起。 从不同的径向方向向内流向凸起的水,以最小的湍流向上平稳向上引导到泵的入口,以优化泵的性能。
