摘要
某型电泵作为特种船舶动力辅助系统的核心设备,其核心组件-多级离心泵,承担着将流体持续泵出,保持系统高效运行的作用。普通的离心泵多是以水为介质,在制造和测试阶段也是以水来评估其性能的。此型电泵由于应用场景特殊,面对粘度显著增加的油介质时,由于介质物理性质的巨大差异,电泵的工作效率往往会受到严重影响,为了确保电泵能够持续保持高效、安全、稳定且合理的运行状态,现深入研究了离心泵中的关键部件叶轮,并对其流道进行了分析,旨在优化泵体内部流体的流动路径,减少因介质粘度增大而带来的额外能量损失和流动阻力,从而显著提升电泵在处理高粘度油介质时的整体性能表现。
As the core equipment of the special marine power auxiliary system,a certain type of motor pump’s core component,the multistage centrifugal pump,undertakes the role of continuously pumping out the fluid and maintaining the high-efficiency operation of the system.The ordinary centrifugal pumps mostly take the water as the medium,of which the performance is also evaluated by water in the manufacturing and testing stages.The application place of this type of motor pump is special.When the pump adopts the oil medium with a significantly-increased viscosity,the working efficiency of it is often seriously affected due to the huge difference in the physical properties of the medium.In order to ensure that the motor pump can continue to maintain an high-efficiency,safe,stable and reasonable operating state,this paper deeply studies the impeller of the key component of the centrifugal pump,and analyzes its flow channel.It aims to optimize the flow path of the fluid inside the pump body,reduce the additional energy loss and flow resistance caused by the increased medium viscosity,thus significantly improve the overall performance of the motor pump when dealing with high-viscosity oil media.
