有關於蒸氣~~

提供有關蒸氣~

例如蒸氣轉換成能量阿~

或是蒸汽機~蒸氣火車~誰發明ㄉ?

只要有關於蒸氣的都可以喔!!

    蒸汽機發明

    詹姆斯?瓦特(James Watt),西元一七三六年元月十九日生於蘇格爾西南部之格陵諾克港,一八一九年八月二十五日逝於伯明罕,享年八十有三。瓦特天資聰穎,記憶特強,尤具語言、音樂與化學天賦。幼承母教,後入文法學校,習拉丁文、希臘文及數學;然奠定其發明根基者,當為乃父之工廠,瓦氏自該處習得製具本事。年十七,瓦氏立志製作數學用具,首至格拉斯哥,旋赴倫敦,受名師指教;一七五七年再返格拉斯哥,製作四分儀、圓規、天秤等數理用具。一七六五年,因鑑於紐柯門式(Nen Comen)蒸汽機甚耗蒸汽,遂發明分離式冷凝器安置蒸汽機上,以救其弊。

    瓦氏除對蒸汽機大加改善外,另有不少其他新的發明與發現。瓦氏為倫敦與愛丁堡皇家學會之成員,並為法國科學學院外籍會員。一八○六年,格拉斯哥大學授之法學博士學位,稍後,瓦氏自謙,婉拒受封男爵頭銜。綜觀瓦氏一生,追求科學新知,發明蒸汽機,將熱能有效轉化為機械能。其舉世聞名之發明,乃科學與工學成功之結合,對「工業革命」有永恆不朽之實質貢獻。

    有個英文網站介紹蒸汽機原理﹐圖文並茂﹐我只能貼文字噢

    Steam Engine Operation

    The following diagram shows the major components of a piston steam engine. This sort of engine would be typical in a steam locomotive.

    The engine shown is a double-acting steam engine because the valve allows high-pressure steam to act alternately on both faces of the piston. The following animation shows the engine in action:

    You can see that the slide valve is in charge of letting the high-pressure steam into either side of the cylinder. The control rod for the valve is usually hooked into a linkage attached to the cross-head, so that the motion of the cross-head slides the valve as well. (On a steam locomotive, this linkage also allows the engineer to put the train into reverse.)

    You can see in this diagram that the exhaust steam simply vents out into the air. This fact explains two things about steam locomotives:

    It explains why they have to take on water at the station -- the water is constantly being lost through the steam exhaust.

    It explains where the "choo-choo" sound comes from. When the valve opens the cylinder to release its steam exhaust, the steam escapes under a great deal of pressure and makes a "choo!" sound as it exits. When the train is first starting, the piston is moving very slowly, but then as the train starts rolling the piston gains speed. The effect of this is the "Choo..... choo.... choo... choo choo-choo-choo" that we hear when it starts moving.

    On a steam locomotive, the cross-head normally links to a drive rod, and from there to coupling rods that drive the locomotive's wheels. The arrangement often looks something like this:

    In this diagram, the cross-head is connected to a drive rod that connects to one of three drive wheels for the train. The three wheels are connected via coupling rods so they turn in unison.

    此外還有幾種應用蒸氣的網站:

    蒸汽機是利用氣壓的原理來運轉的..因為水蒸發水蒸氣會增加壓力,這葛壓力會推動活栓,活栓被推過去後因為構造的關西又會被推回來,於是因為壓力的關西水蒸氣又變成了水,並一直重複以上的動作,使得蒸汽機運轉

    ㄏㄏ!你知道我是誰嗎?你跟我問一樣ㄉ問題ㄟ

    很早以前,人們就知道用鐵軌來搬運東西,到了瓦特發明蒸汽機,便有人利用蒸汽機來製造汽車,也有人利用蒸汽機來發展火車。直到西元1814年,英國人喬治‧史蒂芬生(George Stephenson)結合前人的智慧與經驗的結晶,成功地發明了第一輛可行駛於鐵軌上的火車頭。

    蒸汽汽缸油可分過濾之汽缸油與未過濾之汽缸油二類,每類又可分為純礦物性汽缸油和複合性汽缸油兩種。過濾之汽缸油其殘碳量少,約為1%左右,適用於使用飽和蒸汽和過熱蒸汽之汽缸。

    未過濾之汽缸油其殘碳量在2 ﹪以上,色澤較深,適用於使用潮濕蒸汽之汽缸。

    複合汽缸油含有3-10%之動植物油脂,能與蒸汽中之濕氣混成乳化狀,且其對金屬表面不易為蒸汽冷凝水份所沖除,而增進潤滑效能。

    使用過熱蒸汽(550℉以上)之蒸汽機需使用純礦物性汽缸油,以免複合油所含之動植物油脂,在遇高溫時裂解生成脂肪酸而侵害機件。
