移动卸料装置在皮带机系统连通改造中的应用

我公司3#装车楼系统配合铁路电气化改造后,输运能力将大幅提高。但是向3#装车楼输送矿石的6#斗轮机堆场,堆存量小,不能充分发挥斗轮机装车的优势。为此公司提出将3#、4}}斗轮机堆场与6#斗轮机堆场的皮带机连通,使3#、4#斗轮机堆场成为6#斗轮机堆场的后方堆场,     

基于污染物分布的隧道双组通风井送排式通风控制研究

为了优化双组通风井送排式纵向通风方式的运营通风控制,降低隧道运营能耗。本文针对长度6.3km公路隧道,利用fluent仿真软件建立了考虑车辆污染物(CO)排放的双组通风井送排式通风的1:1三维数值仿真模型,并采用k-ε湍流模型进行了数值计算。根据数值计算结果,分析了通风风量对隧道内污染物浓度的分布的影响规律。研究结果表明:1#、2#通风井将隧道分为3个通风段,1#通风井近隧道入口,2#通风井近出口,随着2#通风井排风量增加,位于2#通风井上游通风段的CO浓度减小,位于2#通风井下游通风段的CO浓度增加;1#通风井送风量大小改变对稀释CO浓度的影响程度大于2#通风井排风量大小改变对稀释CO浓度的影响程度。

超大型船舶安全靠泊湛江港400#泊位的操纵

<正>船舶靠泊的相关情况1.泊位400#泊位在油码头201#泊位的西北侧,即201#泊位在码头向北延长线西侧约110米,泊位南端距201#泊位的北系缆墩约100米,而且该水域是203#、204#、206#三个泊位的入口航道,在本泊位港池以南的水域,水深锐减,小于8米。400#泊位真方位是011-191°,长度为330+40米,港池水深为18米,泊位前沿水深为22米,回旋水域的直径为600米,在409#泊位的仓库附近有一对导标,标示出港池的中线。     

散化肥螺旋卸船机行走机构改造

1 问题的提出 新沙公司目前共有泊位7个,其中3#泊位是通用泊位,码头前沿配有门机5台;4#泊位是散化肥专业泊位,码头前沿配有螺旋卸船机1台;5#、7#泊位是杂货泊位,码头前沿各配有门机3台.3个通用或杂货泊位一共只有11台门机,平均每个泊位不足4台.这3个以门机为主力卸船机的泊位,又被3个专业泊位分割开,相互之间无法沟通,门机无法调配.特别是3#泊位和5#泊位,泊位占用率分别达到34.4%和27.5%,但只能各顾各,极大地影响了卸船效率.要改变这个局面,提高3#和5#泊位的卸船效率,最简单的办法就是对4#泊位的螺旋卸船机进行改造,使之能移开,让3#和5#泊位之间的门机能自由调配.     

“穿梭”轮主机连杆瓦熔化原因分析及修复

1发现问题2008年，我厂承接了一条由散货船改装为汽车滚装船“穿梭”轮的改装工程。并对主机部分运动件和固定件进行了抽检，试车过程中，连杆大端的轴承熔化。这条船的主机是MAN—Mitsubishi柴油机公司生产的8L58／64型直列柴油主机。船东提供的修理项目中要求将1#、3#、5#、7#汽缸进行吊缸检修，其余各缸的曲轴轴承及全部主轴承就地更换，船供备件。同时应船东要求，对1#、3#、5#、7#连杆在厂房内进行了平台检测。连杆大端座孔与小端的平行度偏差为0．015～0．020mm，符合说明书使用要求。活塞、活塞环等部件为常规测量，更换备件。     

集装箱轮被撞后的应急抢险

原油船长期装载成品汽、柴油的货舱防腐

某原油船,1994年大连船厂建造,1999年3月起国内航线运输成品油,主要油品是0#柴油,90#、93#、97#汽油,MDO,FO((180 cst)等。原油船货舱没有涂层,运载成品油,尤其是氧溶解度高的0#柴油和90#、93#、97#汽油,面临最大的难题是如何减缓货舱腐蚀。该轮自改运成品油至今11年,3次坞检,全部肋骨、纵骨、主甲板、各货舱舱壁板及其与主甲板之间的肘板(肋板)等没有腐蚀穿孔,测厚数据符合CCS规范,

Catalyzing Coastal Management in Kenya and Zanzibar: Building Capacity and Commitment

Site-based projects were initiated in Chawka Bay-Paje, Zanzibar, and Nyali-Bamburi-Shanzu, Kenya, to demonstrate the benefits of an integrated coastal management (ICM) approach for addressing coastal issues such as tourism development and enhancement of resource-dependent village economies in eastern Africa. A two-year, multidonor project used three primary strategies to make rapid, but sustainable, progress toward ICM. These included using interagency government teams for ICM planning, adopting an internationally recognized framework for ICM as a project ''road map,'' and explicitly incorporating capacity-building strategies into all aspects of the project. Within two years, integrated ICM action strategies, prepared through participatory processes, were being implemented at both sites, and both teams were working to expand the scale and scope of ICM in their nation. More importantly, the project helped create committed, capable, interagency groups that continue to work together to address urgent ICM issues.
