“此举旨专为公共安全、消费者保护和商场不断增加的人流量设计，”H说到。

"This is designed for public safety, consumer protection and to start increasing the foot traffic into the stores, " Halloran said.

基于加大流量设计法，采用增加分流叶片和增大喉部面积等措施，研制了高效区宽离心泵。

The centrifugal pump with wide efficient range is developed based on the maximum flow design method.

研究表明，排污泵考虑效率和通过能力而进行的加大流量设计导致了轴功率随流量上升过快更容易发生过载这一问题，是可以通过合理的水力设计得到解决的。

The research results in the paper shows that the brake horsepower overload resulting from the design of larger capacity of sewage pump can be solved by reasonable design.
