船用离心泵的运行振动和噪声不仅对机组本身的动力性能和运转指标带来影响,而且还会恶化工作环境,影响运行维护人员的身心健康,降低船舶的目标探测、通讯联络质量和有关的船舶性能。本文主要从离心泵本身的结构设计要素出发,对合理设计机组结构,特别是泵过流部件结构形状和参数以降低其运行振动和噪声的有关方法进行了综合和小结。 The operation vibration and noise of marine centrifugal pumps not only affect the dynamic performance and operation indexes of the unit itself, but also deteriorate the working environment, affect the physical and mental health of operation and maintenance personnel, reduce the target detection and communication quality of ships and the related ships performance. Based on the structural design of the centrifugal pump itself, this paper summarizes and summarizes the reasonable design of the unit structure, especially the structure and parameters of the pump flow-through components to reduce the vibration and noise of the pump.
