研究流体在泵与风机内的流动规律要从泵与风机的原理和性能入手,就是要,进而找出流体流动与各过流部件几何形状之间的关系,确定适宜的流道形状,从而得到符合要求的水力(气动)性能。
To study the fluid flow in the pump and the fan from the pump and the fan principle and performance of the start, it is necessary to find out the fluid flow and the relationship between the flow of parts geometry to determine the appropriate shape of the flow to get Meet the requirements of hydraulic (pneumatic) performance.
