针对湿法磷酸浓缩装置轴流泵故障率高的问题,分析其原因并采取了相应的改造措施。通过提高电动机功率、增大叶轮直径、优化电动机与轴流泵的传动方式、调整轴流泵的密封结构形式,湿法磷酸浓缩装置的实际产能由80.0 kt/a提高至98.8 kt/a,超过了设计产能(85.0 kt/a)。
Due to high failure rate of the axial-flow pump in the wet-process phosphoric acid concentration unit, the reasons are analyzed and corresponding reform measures are taken. By increasing the motor power, increasing the impeller diameter, optimizing the transmission mode of motor and axial-flow pump, and adjusting the sealing structure of axial-flow pump, the actual capacity of wet-process phosphoric acid concentration unit has increased from 80.0 kt/a to 98.8 kt/a, which exceeded the design capacity (85.0 kt/a).
