隨壓強(qiáng)和溫度的變化而變化。嚴(yán)格意義上，任何流體都是可壓縮的，但簡(jiǎn)化起見，常將可壓縮性很小的流體近似地視為不可壓縮流體，即密度為常數(shù)，這就是不可壓縮流體假設(shè)?？梢宰鞔思僭O(shè)的條件可依據(jù)公式有兩種途徑： 1、流體的彈性模量很大，即使壓強(qiáng)變化并不很小，但仍使密度變化很小，大多數(shù)液體的流動(dòng)屬于此類，因此通常將液體視為不可壓縮流體，江蘇流體工廠，除非壓強(qiáng)變化特別大的情況，如水下、封閉管道中的水擊等現(xiàn)象； 2、壓強(qiáng)變化很小，江蘇流體工廠，江蘇流體工廠，以至于彈性模量并不太小時(shí)，密度變化也很小，氣體的大多數(shù)低速流動(dòng)屬于此類。不可壓縮流體和流體的不可壓縮流動(dòng)是兩個(gè)概念。但只要是一種均質(zhì)的流體，兩種提法都意味著密度時(shí)時(shí)、處處相等。流體在靜止時(shí)不能承受剪應(yīng)力。江蘇流體工廠</p><div

1、兩軸相對(duì)位移的大小和方向。當(dāng)安裝調(diào)整后，難以保持兩軸嚴(yán)格精確對(duì)中，或工作過程中兩軸將產(chǎn)生較大的附加相對(duì)位移時(shí)，應(yīng)選用撓性聯(lián)軸器。例如當(dāng)徑向位移較大時(shí)，可選滑塊聯(lián)軸器，角位移較大或相交兩軸的聯(lián)接可選用萬向聯(lián)軸器等。 2、聯(lián)軸器的可靠性和工作環(huán)境。通常由金屬元件制成的不需潤(rùn)滑的聯(lián)軸器比較可靠；需要潤(rùn)滑的聯(lián)軸器，其性能易受潤(rùn)滑完善程度的影響，且可能污染環(huán)境。含有橡膠等非金屬元件的聯(lián)軸器對(duì)溫度、腐蝕性介質(zhì)及強(qiáng)光等比較敏感，而且容易老化。 3、由于制造、安裝、受載變形和溫度變化等原因，當(dāng)安裝調(diào)整后，難以保持兩軸嚴(yán)格精確對(duì)中。存在一定程度的x、Y方向位移和偏斜角CI。當(dāng)徑向位移較大時(shí)，可選滑塊聯(lián)軸器，角位移較大或相交兩軸的聯(lián)接可選用萬向聯(lián)軸器等。當(dāng)工作過程中兩軸產(chǎn)生較大的附加相對(duì)位移時(shí)，應(yīng)選用撓性聯(lián)軸器。流體在流動(dòng)時(shí)，相鄰流體層間存在相對(duì)運(yùn)動(dòng)，流體層之間會(huì)產(chǎn)生摩擦阻力，成為粘滯力。</p><div

聯(lián)軸器是將兩軸軸向聯(lián)接起來并傳遞扭矩及運(yùn)動(dòng)的部件并具有一定的補(bǔ)償兩軸偏移的能力，為了減少機(jī)械傳動(dòng)系統(tǒng)的振動(dòng)、降低沖擊尖峰載荷，聯(lián)軸器還應(yīng)具有一定的緩沖減震性能。聯(lián)軸器有時(shí)也兼有過載安全保護(hù)作用。聯(lián)軸器是在機(jī)械設(shè)備中聯(lián)接兩個(gè)傳動(dòng)部件的紐帶，是工業(yè)傳動(dòng)的一個(gè)重要組成部份。根據(jù)不同的類型、性能、用途可以分為以下幾大類： 1、根據(jù)類型分為以下較常見幾類：金屬膜片聯(lián)軸器：適用于伺服電機(jī)、編碼器、行星減速機(jī)、滾珠絲桿、壓縮機(jī)、混合機(jī)、造紙機(jī)械、機(jī)器人等機(jī)械設(shè)備。梅花型聯(lián)軸器：適用于編碼器、伺服系統(tǒng)、馬達(dá)主軸傳動(dòng)、包裝機(jī)械、機(jī)床傳動(dòng)、泵等機(jī)械。波紋管聯(lián)軸器：適用于編碼器、數(shù)控機(jī)床、定位系統(tǒng)、滾珠絲桿、分度盤、行星齒輪減速機(jī)。彈簧聯(lián)軸器：適用于旋轉(zhuǎn)編碼器、步進(jìn)馬達(dá)、絲桿等。平行式聯(lián)軸器：適用于步進(jìn)電機(jī)、編碼器、絲桿等連接。十字滑塊聯(lián)軸器：適用于轉(zhuǎn)速計(jì)、編碼器、絲桿、機(jī)床等機(jī)械。流體是液體和氣體的總稱。浙江輕型軟管流體產(chǎn)品工廠</p><p style="text-indent:25px">單組分氣體、多組分氣體或彼此能溶解的液體都是單相流體。江蘇流體工廠</p><p style="text-indent:25px">聯(lián)軸器的使用注意事項(xiàng): 1、聯(lián)軸器日常保養(yǎng)時(shí)，如發(fā)現(xiàn)壓痕等正常磨損現(xiàn)象，應(yīng)及時(shí)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(shí)，將十字軸調(diào)轉(zhuǎn)180°，以達(dá)到軸頸受力交替使用。 2、齒輪聯(lián)軸器齒寬接觸長(zhǎng)度不得小于70%；其軸向竄動(dòng)量不得大于5mm。 3、齒輪聯(lián)軸器的齒厚磨損，對(duì)起升機(jī)構(gòu)超過原齒厚的15%時(shí)，對(duì)運(yùn)行機(jī)構(gòu)超過25%時(shí)應(yīng)報(bào)廢，有斷齒時(shí)也應(yīng)報(bào)廢。 4、柱銷聯(lián)軸器的彈性圈，齒輪聯(lián)軸器的密封圈,如有損壞老化，要注意及時(shí)更換。 5、在工作運(yùn)轉(zhuǎn)中，應(yīng)經(jīng)常觀察萬向聯(lián)軸器是否發(fā)生異常的徑向擺動(dòng)和軸承發(fā)熱等現(xiàn)象，發(fā)現(xiàn)這些現(xiàn)象必須及時(shí)維修。江蘇流體工廠</p></p><br
