The water flow velocity in the suction pipe, which is crucial for evaluating the performance on pumping fish, can be measured by the pumped water flow rate of the riser in an air lift pump system.

气力提升泵的水输送量反映了提升管进口的流速情况，而进口流速是衡量吸鱼效果的重要因素。

I would hope that they would be very careful in deploying those with cables and remote operating vehicles, not to pump and break off the riser pipe.

我希望，他们将在部署与电缆和遥控操作车辆，而不是那些泵，打破了隔水管管道非常小心。
