文章就船用泵选型时经常遇到的几个主要问题如启动前的引水、管路的支承、转轴的密封、轴承的布置和主要零件制造材料的选择等等进行了概括性地叙述,同时还从船舶的实践出发,对选用离心泵或容积泵作为主要船用泵型式时的利弊进行了较为详细地分析比较,其中还较为突出地讨论了货油泵。在叙述和分析比较过程中,作者对船用泵设计参数的选取、机组和泵及其附件结构型式的确定以及机组和附件在船舶上的布置等方面的问题,都提出了定性或定量的建议。
The paper briefly describes several main problems often encountered in the selection of marine pumps such as the diversion of water before starting, the support of the pipeline, the sealing of the shaft, the arrangement of the bearings and the selection of materials for manufacturing the main parts, etc. Meanwhile, Also from the ship’s practice, the choice of centrifugal pumps or positive displacement pumps as the main advantages and disadvantages of the ship were analyzed in more detail, of which the more prominent discussion of the cargo pump. During the process of narration, analysis and comparison, the authors put forward some qualitative or quantitative suggestions on the selection of design parameters of marine pumps, the determination of the structural styles of units and pumps and their attachments and the layout of units and attachments on ships.
