摘　　要：工程塑料作为一类新型的材料越来越广泛地应用到农用水泵当中,并逐渐被人们所认识。但是,对工程塑料的选用却仅仅停留在经验上,缺乏使用的依据。为此,采用强度计算方法,对几种农用水泵叶轮的强度进行了校核。结果表明:PPO的性能最好,UHMWPE和PP只有部分牌号的材料能够满足强度要求,而PVDF则不能满足强度要求。此结果为水泵用工程塑料的选择提供了理论依据和方法。Engineering plastics is widely used in water pump for agriculture. It is recognized as a new kind of material, but the choice is relied on experience. The intensity of water pump shrouds for agriculture made of engineering plastics was proofreaded by using the formula. It is drawn that PPO is the best, while UHMWPE and PP can be used partly, PVDF could not meet the intensity requirement. It can provide the theory and way for engineering plastics that used in pump.
