螺旋溜槽断面环流的产生： 液流在螺旋槽面上运动的过程中，由于不断的改变其运 动方向，因而在螺旋槽横断面上产生了离心力，离心力使液流在螺旋槽横断面上形成从横面的外缘到内缘的横向液面坡降。横向离心力和横向液面坡降综合作用的结果，在螺旋槽的横断面上，上层水流中的液体质点受横向合力流向槽的外缘，下层水流中液体质点因横向液面坡降流向内缘流动，中层流液横向流速为零。这种水流运动的连续性形成了螺旋槽断面环流。而内缘水层薄，流速小。外缘水层厚，流速大。另外槽面横向倾角也对断面环流有强化作用

Choose gold equipment circulation generating section of the spiral chute:
Spiral chute section circulation liquid flow movement along the spiral surface, due to constantly changing the moving direction and in the cross section of a spiral groove produced centrifugal force, centrifugal force makes the liquid flow from the horizontal surface of the outer to the inner margin of the lateral surface gradient is formed in the cross section of a spiral groove. Results of horizontal centrifugal force and lateral surface slopes and in the cross section of the spiral groove, liquid particles in the upper water by lateral force flow slot edge, lower flow liquid particles due to the lateral surface at the inner edge of the gradient flow flow, laminar liquid cross flow velocity is zero. The continuity of the flow movement forms the spiral groove section circulation.. While the inner layer is thin, the flow rate is small. The outer layer thickness, high velocity. In addition, the lateral inclination of the groove is also enhanced to the cross section circulation
