一种串列轴流式喷水推进泵的设计

Design of a Tandem Axial Flow Waterjet Pump

为了提高喷水推进泵的推进效率和抗气蚀性能,本文设计了一种串列轴流式喷水推进泵,其主要结构包括泵体、隔板、端盖、电机、转轴、机械密封装置等部件。本泵通过设置独特的机械密封装置,能够有效提高转轴与透孔之间圆周间隙处的密封效果,来避免转轴与通孔之间的圆周间隙处发生渗漏。

In order to improve the propulsion efficiency and anticavitation performance of the waterjet pump,a tandem axial flow waterjet pump is designed in this paper.Its main structure includes the pump body,diaphragm,end cover,motor,rotating shaft,mechanical seal device and other components.The pump can effectively improve the sealing effect at the circumferential gap between the shaft and the through hole by setting an efficient mechanical seal to avoid leakage at the circumferential gap between the shaft and the through hole.
