The invention comprises sprinkler, water pipe, water valve, and pump with large flow or high-level water tank. Sprinklers are set on the water pipe evenly. The upper of water pipe is connected with the pump with large flow or high-level water tank by water valve. In installing said sprinklers are located above the spray nozzle of surface evaporative air cooler.

本发明包括喷头、水管、水阀、大流量水泵或高位水箱，水管上均匀设置喷头，水管的上游通过水阀连接大流量水泵或高位水箱，安装时所述喷头位于表面蒸发式空冷器喷淋管的上方。

No water pump: Reason: did not fill pump and suction hose water; water level below the pump filter pipe; suction tube rupture.

水泵不出水：产生原因：泵体和吸水管没灌满引水；动水位低于水泵滤水管；吸水管破裂等。

The results show that the increase of the buoyancy force by increasing the diameter and length of buoyancy modules is favorable for improving the static performances and reducing the requirements for the top tension of the riser, but arranging the buoyancy modules on lower joints of riser string can lead to hard operations of hang off, installation and retrieval of the riser, there fore the arrangement of buoyancy modules and slick riser joints should be considered carefully.

通过增加浮力块的直径和长度增加隔水管的浮力，有助于改善隔水管的各种静态性能，降低对顶张力的要求，但是在下部安装浮力块对隔水管的悬挂、安装及回收不利，因此需要综合考虑。

Through the details simulation calculation of typical operation conditions of turbine, some conclusions are showed: the design of the overflowing parts is appropriate; the flow in the draft tube is smooth in the optimal operation conditions, the rotation direction of the vortex band is reversed to the runner in the large flow, and the rotation direction of the vortex band is identical to the runner in the small flow.

通过对水轮机典型工况点的详细计算分析，可以看出：各过流部件的设计符合设计要求；同时在最优工况下，尾水管没有明显的偏心涡带，在大流量工况下，尾水管直锥段内有与旋转方向相反的涡带；在小流量工况下，尾水管直锥段内有与旋转方向相同的涡带。
