style="text-indent:25px">流體管可以用鋼材制造，也可以用銅，鈦等有色金屬制造，甚至可以由塑料等非金屬材料制造。流體管必須具有中空截面，但也可以是方形，三角形或其它任何形狀，有些裝備受條件限制，就必須采用矩形管，但是絕大多數(shù)還是使用圓管。圓管在所有幾何截面中具有小的周長(zhǎng)/面積比，即在使用同樣數(shù)量材料的條件下，可以獲得大的內(nèi)截面。鋼管由于其成本低廉，強(qiáng)度高，在現(xiàn)代社會(huì)流體輸送中得到多應(yīng)用。鋼管按其生產(chǎn)工藝，分為無縫鋼管和焊管兩大類，其中焊管又分為高頻直縫焊管（ERW）,螺旋焊管（SSAW）,埋弧焊管（UOE）等。山東PU軟管流體設(shè)備廠家流體適用范圍：用于流體產(chǎn)品質(zhì)量控制。</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滑的聯(lián)軸器比較可靠；需要潤滑的聯(lián)軸器，其性能易受潤滑完善程度的影響，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。</p><p

1.根據(jù)機(jī)械特性的要求，如有無齒隙、抗扭剛度高低、振動(dòng)沖擊力吸收等等，選擇合適的聯(lián)軸器型式。 2.由驅(qū)動(dòng)機(jī)械（如電機(jī)）動(dòng)力 [KW,HP] 及聯(lián)軸器使用回轉(zhuǎn)數(shù) [N] 求得聯(lián)軸器承受的轉(zhuǎn)矩 [TA] TA(Kg.m)=973.5×KW/N(rpm)=716.2×HP/N(rpm)或 TA(N·m)=9550×KW/N(r/min) 3.由被正系數(shù)表中查得負(fù)載條件系數(shù) K1 ，運(yùn)轉(zhuǎn)時(shí)間系數(shù) K2 ，起動(dòng)停止頻度系數(shù) K3 ，周圍環(huán)境溫度系數(shù)K4 ，求得補(bǔ)正扭力 [TD] 。 TD=TA · K1 · K2 · K3 · K4 4.選用聯(lián)軸器的常用轉(zhuǎn)矩必須大于被正轉(zhuǎn)矩。 5.聯(lián)軸器所能承受的較大扭力必須大于原動(dòng)側(cè)及被動(dòng)側(cè)雙方所產(chǎn)生的較大扭力。 6.確定孔徑范圍是否適用。 7.除了以上的選定步驟外，對(duì)于振動(dòng)頻率亦須檢討。即轉(zhuǎn)矩變動(dòng)的頻率與軸的固有振動(dòng)數(shù)避免造成共振的現(xiàn)象產(chǎn)生。由于流體宏觀運(yùn)動(dòng)產(chǎn)生的熱量遷移，分為自然對(duì)流和強(qiáng)迫對(duì)流兩種。山東PU軟管流體設(shè)備廠家</p><p
