耙吸式挖泥船液压系统设计 摘要 耙吸式挖泥船是一种边走边挖的挖泥船，其中的挖装泥和卸泥这一切的工作都是由它本体来进行的。耙吸船工作的方法就是靠着疏浚装舱法，将其装满后，就前往倾倒区，把船舱内的泥土倒入水中，再之后回去继续工作，一直循环如此。耙吸式挖泥船具有灵活机动，高效，抗风抗浪能力强等特点，还有它可以在水的下面工作比如挖硬软土。十分可以在沿海港口、航道、开广的河面和船舶锚地工作。 耙吸式挖泥船现在作为一种常见的用于港口基建工程和水利工程的挖泥船，我们在这里主要讲解其液压系统，耙吸式挖泥船其传动主要靠的是液压系统，所以液压系统的好坏则能看出一个耙吸式挖泥船的好坏程度。本篇主要是用来设计其液压系统主要有以下几个方面： （1）耙吸式挖泥船液压系统的方案选择及其工作原理 （2）耙吸式挖泥船液压系统设计 关键词：耙吸式挖泥船；液压系统方案；液压系统设计； Abstract The traili
