查询词典 pump-out

Concrete pump is a construction device which pumps concrete depending on the pressure in the pipe. It is able to complete horizontal and vertical transportation continuously at the same time and it has charateristics of high effiency, labor saving, low cost, long transportation distance, and high pumpage. Concrete pump is an perfect device for modern transportation, especially for the confined sites and construction fields filled with roadblock where other transportation tools cant get close to directorly.

混凝土泵是通过管道依靠压力输送混凝土的施工设备，它能一次连续地完成水平运输和垂直运输，输送效率高、劳动力省、费用低，混凝土泵运输距离长，单位时间内的输送量大，尤其对于一些工地狭窄和障碍物的施工现场，用其他运输工具难以直接靠近施工工程，混凝土泵则能有效地发挥作用，是较为理想的一种现代混凝土输送设备。

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。
