文档介绍：绞吸式挖泥船定位桩液压系统设计
摘要
绞吸式挖泥船经过一百多年的发展,已经成为挖泥船王国中所占比例最大的船型。绞吸式挖泥船的工作原理:利用机械式的挖泥刀具将疏俊区底部的泥土绞碎,通过船上离心泥泵的旋转产生的真空将挖掘的泥浆经吸入管吸入、提升再通过船上排泥管排出的过程。由于绞吸式挖泥船能够将挖掘、输送、排出和处理泥浆等疏浚工序一次完成,能够在施工中连续作业等优点,目前,绞吸式挖泥船被广泛应用于港口、航道的疏浚和陆地吹填工程。它是一种高技术含量船型,定位桩系统是绞吸挖泥船的主要系统之一,结构复杂,技术含量高,存在大量的设计关键技术和难点。本文主要介绍了“天狮号”绞吸挖泥船主要参数,绞吸式挖泥船的工作原理和定位桩工作原理。本设计的主要特点是:挖泥船操作容易,同时还减少了误操作的可能性,提高了系统的安全性;减少了阀件总数,系统布置得到了简化,非常有利于系统运行中总效率的提高,能耗降低,也减少了若干设备投资的费用;有利于减少系统的故障发生率、减少检测维修等非作业时间,提高了实际工作的时效。本设计详细的阐述了该定位桩液压系统及各类液压元件的计算选择,以及系统的验算过程。

ABSTRACT
The cutter suction dredger after 100 years of development, has e the largest dredger of the Kingdom of the proportion of the ship. Cutter suction dredger works: Using a mechanical tool to Shu Chun dredging the bottom of the soil area undercooked ground, through the board's rotation centrifugal mud pump vacuum to dig the mud by the suction pipe inhaling, raise and then by boat sludge discharge pipe discharge process. As the cutter suction dredger will be mining, transport, discharge and so mud dredging and disposal process pleted, can the construction of continuous operation and other advantages, at present, a cutter suction dredger is widely used in ports, waterway dredging and Land Reclamation Engineering. It is a high-tech ship type, location pile system is a cutter suction dredger one of the major systems, complex, high technology, there are a large number of key technologies and design difficulty. In this paper, for a "lion numbers," the main parameters of cutter suction dredger, cutter suction dredger the principle and orientation of pile works. The main features of this design are: dredger, easy to use, while also reducing the possibility of misuse and improve the system's safety; reduce the total number of valves, the system layout has been simplified, the system is very beneficial to the operation of the total efficiency increase, reduce energy consumption and also reduces the cost of certain equipment investment; help reduce the incidence of syst
