一、概述

本船航行内河B级航区，主要针对一些打桩船、挖泥船等工程船起抛锚等辅助作业。动力装置按照中国船级社《钢质内河船舶入级与建造规范》（2002）以及2003、2004修改通报等有关规定进行设计。

本船主要参数：总长30.30米，两垂线间长28.65米，型宽8.00米，型深1.55米，吃水0.80米，续航力约40小时。

推进装置采用单机、单桨艉机型柴油机动力装置。

机舱设于#5～#17肋位间，全长6.00米。机舱铺设花钢板，花钢板距基线的高度约为0.46米。

二、动力装置

a.主机参数：主机选用上柴股份有限公司生产的6135Ca型柴油机一台。该柴油机的主要参数为：缸径135 mm；冲程150 mm；缸数6；额定功率为88.3 KW；额定转速为1500 r/min；12 h功率时燃油耗率≤229.8 g/KW.h；12h功率时滑油耗率≤2.04 g/KW.h。采用闭式循环冷却，主机启动方式为24V电启动，主机配启动电机。

b.齿轮箱型号：减速齿轮箱采用杭州发达齿轮箱厂生产的135型倒顺离合船用减速齿轮箱，实际减速比为4.65:1。

c.柴油发电机组参数：柴油机主机选用上柴股份有限公司生产的4135Ca型柴油机一台。该柴油机的主要参数为：缸径135 mm；冲程150 mm；缸数4；额定功率为58.8 KW；额定转速为1500 r/min；12 h功率时燃油耗率≤228 g/KW.h；12h功率时滑油耗率≤2.04 g/KW.h。发电机选用上海马拉松电机设备有限公司生产的T2XV-50-4型发电机。该发电机的主要参数为：额定功率：50KW，额定电压： 400V额定电流： 90.8A。

d.轴线定位：机组位于#10～#14肋位间，齿轮箱输出法兰位于#10肋位。轴系理论中心线距基线高度为： #4肋位高100 mm，#17肋位高445 mm。

我厂汽轮机为东方汽轮机厂生产的C35-8.8./0.785高温高压单缸抽汽凝汽式汽轮机。额定负荷：35MW，转速3000rpm，进汽量220T/H ，抽汽量120T/H，额定压力8.83MPa，温度535℃，配汽方式采用喷嘴配汽，抽汽方式为旋转隔板方式高压双排窗孔喷嘴调节。转子共分为19级：1个高压级+9个压力级+1个低压级+8个压力级，采用回热循环，分别从转子第5、7、10、12、15、17级后抽出部分做过功的蒸汽加热给水，其中第10级后抽汽为可调节式供热，除氧抽汽器，乏汽排至凝汽器。我厂的凝汽器为双路双道制表面回热方式，通过4台循环泵向凝汽器提供冷却水，流经3650根铜管，流量为550T/H，冷却面积为2000㎡，迅速冷却后汽缸排汽，建立真空。同时利用2台射水抽汽器抽出凝汽器不凝结的气体，从而维持凝汽器的真空。

凝结水系统由两台6LDTN-120m-70.6kw的凝结水泵、1台轴加和3台低加组成，从凝汽器抽出的凝结水经过加热后，进入除氧器除氧。我厂的除氧器为HXC-250旋膜压力除氧器，出力为250T/H，温度为158℃，经过除氧器除氧后的水通过给水泵升压后和2台高加加热后进入锅炉。汽轮机的调整符合分为电负荷和热负荷两部分.

调节保安系统技术规范

1、汽轮机的额定转速为3000 rpm。

2、调节系统在额定蒸汽参数，额定真空和主汽阀全开时能维持机组空转，转速摆动数值不大于15rpm。

3、调节系统能保证汽轮机和其他机组并列稳定运行。

4、调节系统有机头手动操作和远方操作装置。

5、调节系统迟缓率ε不大于0.3%。 6、空负荷时，同步器使汽轮机转速在额定转速的-6%～+（δ+2）%范围内变化。

7、调节系统的转速不等率δ在3%～6%范围无级调整，无特殊要求的定货出厂时δ调整为5%。

8、汽轮机在额定蒸汽参数和额定转速下，甩额定负荷时，调节系统能维持机组空转不引起危急遮断器动作。

9、超速保护装置；
