| 摘 要： | 扬黄用泵中的水泵密封环，因黄河含沙水的磨损和汽蚀，密封环配合面磨损快，容积损失增大，从而使水泵的运行效率降低、能耗高。固海扬水管理处应用改进 性聚氨酯弹性体研制成的新型密封环，通过试验证明，其抗磨蚀，抗汽蚀性能极强，能成几倍地延长使用寿命，从而提高了水泵的平均运行效率，节能效果明显。

| Abstract: | The water pump wearing ring is used in electric irrigation, due to cavitation and wear characteristic of the sand-laden water of Yellow River. The conjugate surface of wearing ring is freted fast and losing-volume is enlarged. The reason is due to pump's operation efficiency reduced and energy-experding enlarged. Our department used the denaturalization polyurethane elastomer substance, developed new type wearing ring. By the experiments, not only the performance of wearing-resisting but also the caritation-resisting are improved. The effects of energy-saving is salient and the value were used widely. |
