style="text-indent:25px">壓差阻力和摩擦阻力：從受力角度分析，物體受到的阻力是流體直接作用在其表面上的。垂直于物體表面的是流體的壓力，其產(chǎn)生的阻力稱為壓差阻力；平行于物體表面的是流體的黏性剪切力，其產(chǎn)生的阻力稱為摩擦阻力。除了這兩種力之外，再?zèng)]有其它的力了。所以物體的總阻力就是壓差阻力和摩擦阻力的合力，壓差阻力與物體的形狀密切相關(guān)，摩擦阻力則主要與物體的表面積相關(guān)。有些地方說除了壓差阻力和摩擦阻力之外還存在誘導(dǎo)阻力，以及激波阻力等，是屬于一種誤解。實(shí)際上誘導(dǎo)阻力和激波阻力都可以歸結(jié)為壓差阻力和摩擦阻力（主要是壓差阻力）。江蘇快速接頭流體元件公司流體包括液體和氣體，具有易流動(dòng)和不能保持一定形狀的特性（與固體相比）。</p><div

style="text-indent:25px">聯(lián)軸器是指聯(lián)接兩軸或軸與回轉(zhuǎn)件，在傳遞運(yùn)動(dòng)和動(dòng)力過程中一同回轉(zhuǎn)，在正常情況下不脫開的一種裝置。有時(shí)也作為一種安全裝置用來防止被聯(lián)接機(jī)件承受過大的載荷，起到過載保護(hù)的作用。聯(lián)軸器又稱聯(lián)軸節(jié)。用來將不同機(jī)構(gòu)中的主動(dòng)軸和從動(dòng)軸牢固地聯(lián)接起來一同旋轉(zhuǎn)，并傳遞運(yùn)動(dòng)和扭矩的機(jī)械部件。有時(shí)也用以聯(lián)接軸與其他零件（如齒輪、帶輪等）。常由兩半合成，分別用鍵或緊配合等聯(lián)接，緊固在兩軸端，再通過某種方式將兩半聯(lián)接起來。聯(lián)軸器可兼有補(bǔ)償兩軸之間由于制造安裝不精確、工作時(shí)的變形或熱膨脹等原因所發(fā)生的偏移（包括軸向偏移、徑向偏移、角偏移或綜合偏移）；以及緩和沖擊、吸振。常用的聯(lián)軸器大多已標(biāo)準(zhǔn)化或規(guī)格化，一般情況下只需要正確選擇聯(lián)軸器的類型、確定聯(lián)軸器的型號(hào)及尺寸。必要時(shí)可對(duì)其易損的薄弱環(huán)節(jié)進(jìn)行負(fù)荷能力的校核計(jì)算；轉(zhuǎn)速高時(shí)還需驗(yàn)算其外緣的離心力和彈性元件的變形，進(jìn)行平衡校驗(yàn)等。具有黏性的流體在發(fā)生變形時(shí)將產(chǎn)生阻力。</p><div
