Reverse flow guide system of vertical axial flow pump
The invention discloses a reverse flow guide system of a vertical axial flow pump. The reverse flow guide system of the vertical axial flow pump comprises a first supporting block, a reverse flow outlet gate, a reverse flow guide pipe, a pump station outlet gate, a reverse flow inlet gate, a second supporting block, a first rotating shaft, a second rotating shaft, a fluid speed sensor and a gate control system, wherein the reverse flow guide pipe is connected with an axial flow pump pipeline; the first supporting block and the second supporting block are both arranged inside the axial flow pump pipeline; the reverse flow outlet gate and the reverse flow inlet gate are arranged at two ends of the reverse flow guide pipe; the first rotating shaft is connected with the reverse flow outlet gate; the second rotating shaft is connected with the reverse flow inlet gate; the fluid speed sensor is arranged at an outlet of the axial flow pump pipeline; the fluid speed sensor is connected with the gate control system; and the gate control system controls the opening and closing of the reverse flow outlet gate and the reverse flow inlet gate. The reverse flow guide system of the vertical axialflow pump has the advantages that the faults of water hammer, machine lifting, runaway and the like caused by reverse flow are avoided, and the operation stability of a pump system is improved.
本发明公开了一种立式轴流泵逆向流导流系统，包括第一支撑块、逆向流出口闸门、逆向流导流管、泵站出口闸门、逆向流入口闸门、第二支撑块、第一转轴、第二转轴与流体速度传感器、闸门控制系统；逆向流导流管与轴流泵管道连接，第一支撑块与第二支撑块均安装在轴流泵管道内部，逆向流出口闸门与逆向流入口闸门安装在逆向流导流管的两端，第一转轴与第二转轴分别与逆向流出口闸门、逆向流入口闸门连接，流体速度传感器安装在轴流泵管道出口处，流体速度传感器与闸门控制系统连接，闸门控制系统控制逆向流出口闸门、逆向流入口闸门的开启与闭合。该导流系统避免了逆向流带来的水锤、抬机、飞逸等故障，增加了泵系统的运行稳定性。
