第三百零三节小型蒸汽机
李迪的私货，美帝的小型蒸汽机在姜野等机械厂一干人的攻关下仿制成功了。龙腾小说网ltxs520.com很多特殊的零部件是孙立和萧贵两个钳工手工制造出来的。这台蒸汽机的锅炉尺寸又特别的小，在很多方面设计的十分巧妙，让这二个钳工颇费了一番脑筋。
尺寸上大了30％，功率上小了25％，总体来说，基本凑合。
“可别小看了它，它和我们带来的锅驼机相比，输出效率高多了。”周比利说，“幸亏是现在仿制，要是一年前还真没法仿制。”
这一年半来机械厂不断的为自己添加各种专用设备，工装也渐渐配齐了。加上不断的生产实践，技能水平提高的很快。对使用自己的手中的工具也变得愈加得心应手。在选择代用材料方面也有了很多经验。
这种小型蒸汽机很快定型投入了量产，因为它重量轻得足可以装备舢板，而这种小型艇的动力化又是穿越集团目前急需的。不仅用于内河交通，还装在稍大一些的小艇上用作港口巡逻警备。
工能委根据指示，把这种蒸汽机安装到交通艇上，改造成拖轮，再按照王洛宾的图纸，制造专用的浅吃水小驳船。展无涯看到图纸大吃一惊。
“王工，你这是驳船吗？”
“当然是驳船。”
“我看怎么和口棺材差不多？”展无涯说，“尺寸稍微大点，水线下面稍有流线型之外，基本就口浮动棺材嘛！”
为了减轻船只的自重，这种小型驳船是用铆接铁板制造的。看上去比木结构的交通艇要单薄多了，当然吃水也浅得多。
“本来就是这样的。”王洛宾说，“这是英国人造了用在运河上运煤用的。”英国是最早将运河大规模系统化的国家，早期的运河水量不多，也没有可靠的动力，经常是用一匹马来牵引，因此走不了大船，有的地方落差大，要用专门的升船机把驳船拉过落差。所以驳船不大，吃水也不能很深。一艘改装过后的小拖轮足够牵引10艘这样的驳船。每艘驳船的载荷大约是2.5吨。
“2.5吨这还不是它的最大承载，是考虑到了安全吃水深度设定的载荷，要是航道状况好点，装4吨是不成问题的。”
不过这东西的吃水的确够浅，能够满足在南渡江上的航行需求。装上了小型蒸汽机的拖船也能勉强通过。当然对拖船的载重要精打细算。燃料不能装得太多，只能满足单程。反正在海家码头也能补充到燃料，问题不算太大。
展无涯打算改装4艘交通艇作为拖船，每艘拖轮单航次可运25吨，机动船的速度比较快，一天可以走两个航次，每天从甲子矿运出的褐煤就是200吨。加上洗煤厂的投产之后运出的是精煤，不再是原先包含有60％杂质的原煤，里外里计算等于把每日运输量提高到了相当于原先运量550吨的水平。煤焦化联合厂足够用了。
“实际上不可能维持这么大的运量的。”展无涯说，“我认为这种蒸汽机的设备完好率不会这么高，扣除定期维护保养和出故障维修的时间，航线上保持3艘拖轮是能办到的，即使这样每天的运量也有150吨了。”
“你太乐观了，要我说，这拖轮用了半年后能维持2艘同时运作你们机械厂就是人品大爆发了。”王洛宾说。
“小蒸汽机半年之后肯定会大规模量产，坏了直接换！”展无涯豪情大发，“只等把田独的铁矿石开回来。”
王洛宾笑了笑，豪情不错，不过事情显然没这么简单。
3000人登陆到一个荒芜的海滩上，其行动规模比d日还要大。而且还要同时在三个方向同时展开工程，相应要准备的物资也就多得多。
临高的全部产能都在满负荷运转，生产登陆榆林堡所需要的各种物资。仅仅是工作服就要准备9000套。原先莫笑安打算制造6000套，在他的计算中，工人每人身上穿1套，再备2套足够了。但是汇报生产计划的时候马千瞩告诉他这个数字不够。
“你没干过基建活，那不是耗衣服，而是吃衣服。一人4套是起码的了。还有鞋子，至少一人3双。”
“靠，这么厉害，计委拨给我的帆布和粗布可不够用了。”
“关照广州再采购一批来好了，”马千瞩想到上次广州就来电说当地有英国的代理商在求售大批印度棉布，价格很便宜，可惜当时库存的国产布都用不完，他也没同意采购这批布。
