在湿法磷酸生产过程中，浓缩系统的稳定运行关键在于轴流泵及石墨换热器，轴流泵为系统的动力设备，其运行正常与否直接影响系统的开停车。运行电流、振动、温度是设备运行的硬性指标，需确保在其正常范围内。通过对轴流泵机械传动部件、性能曲线、系统的工艺指标分析设备故障所在，及早消除隐患，降低运行风险、节约检修成本，提升管理水平，保证系统稳定、周期运行，发挥产能。“,”in the process of WPA production, the key to the stable operation of the concentration system is the axial flow pump and graphite heat exchanger. The axial flow pump is the power equipment of the system, and its normal operation directly affects the start-up and shutdown of the system. Operating current, vibration and temperature are the rigid indexes of equipment operation, which should be ensured within their normal range. Through the analysis of mechanical transmission parts, performance curve and system process index of axial-flow pump, the equipment failure can be eliminated as soon as possible, the operation risk can be reduced, the maintenance cost can be saved, the management level can be improved, the stable and periodic operation of the system can be guaranteed, and the production capacity can be exerted.
