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.
