style="text-indent:25px">流體力學是在人類同自然界作斗爭和在生產(chǎn)實踐中逐步發(fā)展起來的。古時中國有大禹治水疏通江河的傳說;秦朝李冰父子帶領勞動人民修建的都江堰，至今還在發(fā)揮著作用;大約與此同時，古羅馬人建成了大規(guī)模的供水管道系統(tǒng)等等。液體的分子距很小，分子間的引力較大，分子間相互制約，分子可以作無一定周期和頻率的振動，在其他分子間移動，但不能像氣體分子那樣自由移動，因此，液體的流動性不如氣體。在一定條件下，一定質(zhì)量的液體有一定的體積，并取容器的形狀，但不能像氣體那樣充滿所能達到的全部空間。液體和氣體的交界面稱為自由液面。</p><p style="text-indent:25px">流體管是一種具有中空截面，從頭到尾的沒有焊縫的鋼管。鋼管具有中空截面，大量用作輸送流體的管輸送石油、天然氣、煤氣、水及某些固體物料的管道等。鋼管與圓鋼等實心鋼材相比，在抗彎抗扭強度相同時，重量較輕，是一種經(jīng)濟截面鋼材，多用于制造結(jié)構(gòu)件和機械零件，如石油鉆桿、汽車傳動軸、自行車架以及建筑施工中用的鋼腳手架等。流體管是專門用于輸送具有流體性質(zhì)介質(zhì)的管材。具有流體性質(zhì)的介質(zhì)，除了如水、油、溶液等液體介質(zhì)以外，水泥，糧食，煤粉等固體介質(zhì)，在一定條件下也可以流動。標準流體分二元、三元和多元標準流體。</p><div

style="text-indent:25px">早期的人們（可能現(xiàn)在很多人也這樣認為）基于某種“常識”，認為物體前部的形狀決定了阻力的大小，前部尖一些阻力就會小。有了邊界層理論后，發(fā)現(xiàn)物體后部的形狀才是更重要的。因為物體后部的形狀決定了邊界層分離的位置，從而決定了物體表面的壓力分布。雖然說物體后部的形狀對阻力大小是決定性的，但前部形狀也是很重要的。例如，物體前部如果是方頭的，流體就會在尖角處早早地分離，后部精心設計的形狀就失去意義了。目前在高速公路上跑的卡車，已經(jīng)實現(xiàn)的形狀優(yōu)化主要集中在前部，后部受集裝箱形狀的限制，所做的工作較少。對于跨聲速運動的物體，激波會產(chǎn)生額外的阻力，所以前部都設計成很尖的形狀，使激波的錐角更小，以減小阻力。流體在靜止時不能承受剪應力。卷管器流體工具專賣</p><p style="text-indent:25px">標準流體引到流體工業(yè)名詞。浙江電纜卷筒流體工具</p><p style="text-indent:25px">聯(lián)軸器的使用注意事項： 1、聯(lián)軸器不允許有超過規(guī)定的軸心線歪斜和徑向位移，以免影響其傳動性能； 2、萬向聯(lián)軸器安裝好以后，正常運轉(zhuǎn)一個班，必須檢查所有緊固螺釘，如發(fā)現(xiàn)松動，必須以規(guī)定的擰緊力矩再次擰緊，這樣反復幾個班，以保證不會松動； 3、萬向聯(lián)軸器滑動面、十字頭、軸承等必須保證潤滑，一般用2#工業(yè)鋰基油脂或2#二硫化鉬鈣基脂，在一般條件下連續(xù)運轉(zhuǎn)500小時加油一次，間斷運轉(zhuǎn)2個月加油一次，若高溫條件下工作必須每周加油一次，加油時把軸承端面油孔螺釘擰下，用高壓油槍注入至溢出為止； 4、聯(lián)軸器日常保養(yǎng)時，如發(fā)現(xiàn)壓痕等正常磨損現(xiàn)象，應及時更換；聯(lián)軸器不允許有裂紋存在，如有裂紋則需更換（可用小錘敲擊，根據(jù)聲音判斷）；在保養(yǎng)拆洗時，將十字軸調(diào)轉(zhuǎn)180，以達到軸頸受力交替使用。浙江電纜卷筒流體工具</p></p><br /><p>文章來源地址:
