求翻译：再用计算出来的叶轮数据依据《离心泵设计基础》画出叶轮的平面投影图。该泵选用三千瓦配套的柴油机，合适选用各零件材料和精度等级，本设计采用联轴器与原动机相连方式。其中还有轴的设计，通过泵的效率及扭矩来确定轴的最小直径，在根据力学来完成校核其强度，如轴向力，圆周力，径向力等。是什么意思？

Then calculated from the impeller data in accordance with the centrifugal pump design basis "to draw the planar projection map of the impeller. The pump is supporting three kilowatts of diesel engines, appropriate selection of materials and precision levels of the various parts of the design connect

With the impeller centrifugal pump data based on the basis of design of the impeller of the picture plane. The pump with the 3000 Watt diesel engine, and the appropriate use of spare parts and materials and precision level, this design uses the coupling connected with prime mover. There are also sha

Then the calculated basis based on the design of centrifugal pump impeller data draws a planar projection of the impeller. The auxiliary diesel engine 3-kilowatt pump selection, selection of suitable materials and precision of parts, this design uses the coupling attached to the prime mover. Axis al

Again uses the impeller data which calculates to rest on "Centrifugal pump Design Foundation" to draw the impeller the plane projection.This pump selects three kilowatts necessary diesel engines, selects various components material and the precision class appropriately, this design uses the shaft co
