聚氨酯密封环的研制

Development the Polyurethane Wearing Ring

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。

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.
