When pump starts, the lower impeller lifts the solution up step by step. And the extreme centrifugal force from the enlarged higher impeller stops the solution as it entering the higher impellr. At the same time, the full solution in the chamber stops the air mixed with the solution in the chamber to go down. This way masterly eliminates both big problems of vertical sealless pump, overflow at high pressure and bubbles at big flow.

塑宝SV泵剖面结构SV Super Series Analytical cross section SV泵剖面结构泵开始运转时，底部叶轮将液体逐步上推，待液体进入上部叶轮时，即受加大之背叶的强大阻力而无法上升，但上部叶轮所卷入液体中的空气，却受阻於水室中贮满的液体而无法下降，如此巧妙地排除了立式无轴封泵高压时溢流，或大流量时吸入空气的两大难题。

Yet more than 25 years have passed since I sat finals and still I wake at night with my heart thudding, dreaming that I had forgotten to revise, or had had to take physics instead of philosophy.

The drawing-room, as I have before observed, was raised two steps above the dining-room, and on the top of the upper step, placed a yard or two back within the room, appeared a large marble basin, which I recognised as an ornament of the conservatory- where it usually stood, surrounded by exotics, and tenanted by gold fish- and whence it must have been transported with some trouble, on account of its size and weight.

如我以前所观察的那样，客厅已垫得比餐室高出两个台阶，在客厅内靠后一两码的顶端台阶上，放置着一个硕大的大理石盆，我认出来那是温室里的一个装饰品——平时里面养着金鱼，周围布满了异国花草——它体积大，份量重，搬到这儿来一定是花了一番周折的。
