Lesson 19 Cargo handling equipment (货物装卸设备) 轮机英语教学

Because of the availability of standard low cost gearboxes this arrangement is popular on light cranes.
Jimei university
Variable capacity axial piston motors have the important advantage that light hook speeds can be increased up to four times from a given oil flow by reducing the motor capacity to 25 per cent of the maximum.
Jimei university
In the cargo winch, spur reduction gearing transfers the motor drive to the barrel shaft.
Jimei university
A warp end(卷绕端) may be fitted for operating the derrick topping lift (顶牵索) (the wire which adjusts the derrick height).

Some cranes are mounted in pairs on a common platform which can be rotated through 360.
The cranes can be operated independently or locked together and operated as a twin-jib crane of double capacity; usually to give capacities of up to 50 tons.

船舶类型 根据载运货物以及货物装卸方式的不同,船舶可分成不同的种类、船级、类型,详见表 1。 最大的三类船型是集装箱船、散货船(装运散装货物如谷物、煤炭、矿石等)和液货船。 上述船型又可根据船级和船型进行更详细的划分。因此,液货船又可以划分为油船、液化气 体船和散装液体化学品船,但是有些时候是组合式的,比如油船/化学品船。 表 1 仅给出了大体的分类。实际中,还有其他组合船型,如多用途散货集装箱船就是一 例。
二冲程循环从活塞离开其行程底部,即下止点(BDC)向上运行开始,气缸侧面的进气口 即扫气口是打开的(图 2-1(a)),排气口也是打开的。经压缩的新鲜空气充入气缸,通过排气 口将上一行程的残余废气吹出。
船舶可明显划分成不同的三个区域:货舱区、居住区和机舱。根据船舶的类型,每艘船 舶各个部分的大小和功能都多种多样。比如油船,货物区由多个纵向和横向隔壁分割成货舱。 其甲板上下均有大量的货物管系。杂货船有多个货舱,其宽度和船宽相当,沿船长方向由多 个横向隔壁分割而成。甲板装有货物装卸设备,并且货舱开口使用钢制货舱盖封闭。船上居 住区的面积将足够满足船员生活的需要,同时还为驾驶台和通信中心提供空间。机舱大小由 所安装的机器的类型以及必要的辅助设备所决定。不过,客船拥有较大的居住区以满足旅客 的需要。(客船)机舱因为需安装空调、减摇鳍以及其他和旅客相关的设备,所以空间可能会 较大。
低速柴油机 常见的典型低速柴油机的平面图和正面图如图 1-1 所示。在该布置图中,柴油机为六缸 直接驱动式。(图中)唯一可见的辅助设备为位于上层的柴油发电机和下层的空压机。机舱中

船舶尺寸 当船舶载货浮于水面时,其排水量与船舶所排水的重量相等,因此,船舶排水量与在密 度为 1.025 t/m3,的海水中不同装载的船舶总重量相等。船舶排水量包括船舶空载排水量及 船舶载重量,其中,船舶载重量即为船舶装载容量,包括船舶推进所需的燃料以及其他必需 品。因此,在任何情况下,船舶载重量代表了船舶实际排水量与空载排水量之间的差值,以 吨为单位表示为:

第 2 课 船用柴油机是如何工作的
柴油机是一种内燃机,通过把燃油喷入高温高压的燃烧室而发火。船用柴油机是一种在 船上使用的柴油机。其工作原理如下:
一定量的新鲜空气被吸入或泵入气缸并被运动的活塞压缩至很高的压力。 空气被压缩时,温度升高,便点燃喷入气缸的油雾。燃油的燃烧对缸内空气的加热,使 空气膨胀并迫使发动机活塞对曲轴做功,随之驱动螺旋桨。 两次喷油期间的运转过程叫一个工作循环。它由一些程序固定的过程组成。这个循环可 在二行程或四行程内完成。四冲程柴油机的工作循环需要四个独立的活塞行程,即吸气、压 缩、膨胀和排气。如果我们把吸气和排气行程与压缩和膨胀行程结合起来,四冲程柴油机就 变成了二冲程柴油机。如图 2-1 (a)~(d)所示。
船舶载重量=船舶排水量一船舶空载排水量(t)
有时候,“吨”一词并不总能表示同样的重量。除公吨外,还有英吨(1 016 kg),也叫“长 吨”,而“短吨”约为 907 kg。
船舶空载排水量并不常用来指示船舶尺寸大小,相反,基于船舶载重能力的船舶载重量, 包括燃油、滑油等常用来指示船舶的尺寸。
机械
布置 当今船上主要安装有三种类型的机械。它们各自的优点随着技术的进步和提高以及经济 方面的因素(如燃料价格)而变化。因此,在这里仅从工程的角度来谈机械的布置。这三种布 置涉及直接传动低速柴油机、带有齿轮箱的中速柴油机和带有齿轮箱驱动螺旋桨的蒸汽轮 机。 为有效工作,螺旋奖必须在低转速下运转。因此,不管原动机的转速如何,螺旋桨必须 保持转速为 80~100 r/min。低速柴油机的转速在此低转速范围之内,因此其曲轴可以和螺旋 桨轴直接相连;而中速柴油机的转速范围为 250~750 r/min,因此不能直接和螺旋桨轴直接 相连,(但)可采用减速齿轮箱来降低转速用于驱动螺旋桨。蒸汽轮机的转速很高,可达 6 000 r/min。同样,必须采用减速齿轮箱来降低转速用于驱动螺旋桨。

船舶
船舶是大型、复杂的交通工具,必须具有较高的可靠性并能在其所在环境条件下,长时 间自行维持运行。船舶主要是两个技能领域的产品:造船工程师和轮机工程师。造船工程师 与船体、建造、船型、居住舱室以及适航性有关,而轮机工程师则负责用于船舶推进和操纵 的各种各样的系统。更确切地说,这些系统是指船舶推进、操舵、锚泊,以及船舶系固、货 物装卸、发电和配电所需的机械设备。造船和轮机工程师在某些方面的职责有重合,如螺旋 桨设计、降低噪声和减少船体振动,以及为船上的许多区域提供工程服务。
