试验双向环形水槽的结构及控制技术

Structure and Control Technique of a Rotating in Two-way Annular Tank

介绍了新研制的双向环形水槽的结构及所应用的变频调速技术、自动切换遥控采样、光电测速等技术,使该水槽的圆环和环槽可以分别在很宽的速度范围内平稳运转;同时便于实验过程中自动多点采样,并可通过设定采样时间参数改变水样的提取量。它是一种用以研究泥沙运动特性的先进辅助设备。

A developed rotating in two-way annular tank is introduced. The frequency conversion timing technique, remote control and automatic switch sampling technique are used. The frequency conversion timing control technique made the wheel and the tank run stably on an expanse of the rotating speed, and the remote control technique made sampling conveniently in the process of the experiment. Regulating of some parameters can change the quantity of collected water sample. The annular tank is good supplementary equipment for studying silt characteristic.
