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

Abstract
The trailing suction dredger is a kind of dredgerwhich is diggingwhilewalking. All thework of digging, loading and unloading is carried out by its body. The method of raking suction ship is to load the cabin by dredging. After filling it up, go to the dumping area, pour the mud in the cabin into thewater, and then go back towork,which has been circulating. Drag suction dredger has the characteristics of flexibility, high efficiency, strongwind andwave resistance, and it canwork underwater, such as digging hard and soft soil. It canwork in coastal ports,waterways, open rivers and ship anchorages.
Drag suction dredger is now a common dredger used in port infrastructure projects andwater conservancy projects. We mainly explain its hydraulic system here. The transmission of drag suction dredger mainly depends on the hydraulic system, so the quality of the hydraulic system can be seen from the quality of a drag suction dredger. This paper is mainly used to design its hydraulic system, mainly in the following aspects：
（1）Scheme selection andworking principle of hydraulic system of trailing suction dredger.
（2）Design of hydraulic system for trailing suction dredger.
Keywords: Trailing suction dredger; Hydraulic system scheme; Hydraulic system design;
