The sucking speed depends on the viscosity of product and length of suctionpipe.
吸取的速度取决于产品的粘度和吸取管的长度。

The water flow velocity in the suctionpipe, 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。
