style="text-indent:25px">由于真空泵有選擇性抽氣，因而，有時(shí)選用一種泵不能滿足抽氣要求，需要幾種泵組合起來，互相補(bǔ)充才能滿足抽氣要求。如一些真空泵對氫有很高的抽速，但不能抽氦，而三極型濺射離子泵，（或二極型非對稱陰極濺射離子泵）對氬有一定的抽速，兩者組合起來，便會(huì)使真空裝置得到較好的真空度。另外，有的真空泵不能在大氣壓下工作，需要預(yù)真空；有的真空泵出口壓強(qiáng)低于大氣壓，需要前級(jí)泵，故都需要把泵組合起來使用。真空設(shè)備對油污染的要求。若設(shè)備嚴(yán)格要求無油時(shí)，應(yīng)該選各種無油泵，如：水環(huán)泵、分子篩吸附泵、濺射離子泵，金華隔水真空泵企業(yè)、低溫泵等。如果要求不嚴(yán)格，可以選擇有油泵，金華隔水真空泵企業(yè)，金華隔水真空泵企業(yè)，加上一些防油污染措施，如加冷阱、障板、擋油阱等，也能達(dá)到清潔真空要求。真空泵用于機(jī)組啟動(dòng)時(shí)抽真空，正常運(yùn)行時(shí)用于抽出凝汽器中未凝結(jié)的氣體。金華隔水真空泵企業(yè)</p><div

style="text-indent:25px">真空泵的作用：是從真空室中抽除氣體分子，降低真空室內(nèi)的氣體壓力，使之達(dá)到要求的真空度。概括地講從大氣到極高真空有一個(gè)很大的范圍，至今為止還沒有一種真空系統(tǒng)能覆蓋這個(gè)范圍。因此，為達(dá)到不同產(chǎn)品的工藝指標(biāo)、工作效率和設(shè)備工作壽命要求、不同的真空區(qū)段需要選擇不同的真空系統(tǒng)配置。為達(dá)到較佳配置，選擇真空系統(tǒng)時(shí)，應(yīng)考慮下述各點(diǎn)：必須檢查確定每一種工藝要求的真空度。因?yàn)槊恳环N工藝都有其適應(yīng)的真空度范圍，必須認(rèn)真研究確定之。在確定了工藝要求的真空度的基礎(chǔ)上檢查真空泵系統(tǒng)的極限真空度，因?yàn)橄到y(tǒng)的極限真空度決定了系統(tǒng)的較佳工作真空度。一般來講，系統(tǒng)的極限真空度比系統(tǒng)的工作真空度低20%，比前級(jí)泵的極限真空度低50%。</p><p style="text-indent:25px">常用真空泵包括干式螺桿真空泵、水環(huán)泵、往復(fù)泵、滑閥泵、旋片泵、羅茨泵和擴(kuò)散泵等，這些泵是我國國民經(jīng)濟(jì)各行業(yè)應(yīng)用真空工藝過程中必不可少的主力泵種。近年來，伴隨著我國經(jīng)濟(jì)持續(xù)高速發(fā)展，真空泵相關(guān)下游應(yīng)用行業(yè)保持快速增長勢頭，同時(shí)在真空泵應(yīng)用領(lǐng)域不斷拓展等因素的共同拉動(dòng)下，我國真空泵行業(yè)實(shí)現(xiàn)了持續(xù)穩(wěn)定地快速的發(fā)展。真空泵的泵體的布置結(jié)構(gòu)決定了泵的總體結(jié)構(gòu)。立式結(jié)構(gòu)的進(jìn)、排氣口水平設(shè)置，裝配和連接管路都比較方便。但泵的重心較高，在高速運(yùn)轉(zhuǎn)時(shí)穩(wěn)定性差，故這種型式多用于小泵。臥式泵的進(jìn)氣口在上，排氣口在下。有時(shí)為了真空系統(tǒng)管道安裝連接方便，可將排氣口從水平方向接出，即進(jìn)、排氣方向是相互垂直的。此時(shí)，排氣口可以從左或右兩個(gè)方向開口，除接排氣管道一端外，另一端堵死或接旁通閥。這種泵結(jié)構(gòu)重心低，高速運(yùn)轉(zhuǎn)時(shí)穩(wěn)定性好。一般大、中型泵多采用此種結(jié)構(gòu)。真空泵口安裝電磁閥時(shí)，閥與真空泵應(yīng)同時(shí)動(dòng)作。</p><div

style="text-indent:25px">真空泵使用說明：1、關(guān)閉泵上方的閥門。2、有冷卻水的泵接通冷卻水。3、近規(guī)定轉(zhuǎn)向手盤皮帶輪數(shù)圈，把泵腔內(nèi)的油排入油箱內(nèi)，確保啟動(dòng)不易噴油。（特別在冬季，油粘大，啟動(dòng)負(fù)荷大，故請注意）。4、啟動(dòng)電動(dòng)機(jī)，泵開動(dòng)運(yùn)轉(zhuǎn)，觀察油窗，檢查油位。油位應(yīng)在油標(biāo)中心，油位偏高，會(huì)造成噴油；油位偏低，會(huì)造成潤滑不良，泵極限壓力達(dá)不到出廠指標(biāo)。加油、放油位置詳見泵指示牌。緩慢打開泵上方的閥門，系統(tǒng)開始工作。泵不工作時(shí)，油窗內(nèi)幾乎看不到油，都進(jìn)入泵體內(nèi)，油位以泵運(yùn)轉(zhuǎn)時(shí)為準(zhǔn)。5、冷卻水的進(jìn)水溫度以不超過30℃為宜，進(jìn)出水溫差以不超過3℃為宜。6、當(dāng)環(huán)境溫度低于5℃時(shí)，應(yīng)將泵油放出加熱到15-30℃后加入泵內(nèi)啟動(dòng)工作。7、泵溫以油溫減去環(huán)境溫度不超過40℃為宜，否則應(yīng)加強(qiáng)通風(fēng)散熱或增加冷卻水流量。有時(shí)為了真空系統(tǒng)管道安裝連接方便，可將排氣口從水平方向接出。金華隔水真空泵企業(yè)</p><p style="text-indent:25px">真空泵特點(diǎn)：在較寬的壓力范圍內(nèi)有較大的抽速。金華隔水真空泵企業(yè)</p><p style="text-indent:25px">在真空泵中真空泵油不僅作為獲得真空的介質(zhì)，而且還對機(jī)械摩擦點(diǎn)起潤滑、冷卻和密封作用。這也是真空泵油的重要的性能，由于真空泵要求真空度很高，一般用石蠟基窄餾分潤滑油，對于擴(kuò)散真空泵，還可使用蒸氣壓很低的硅油或其他合成油。真空泵腔內(nèi)容積不斷變化而形成排氣作用，要求潤滑油應(yīng)具有合適的粘度和粘溫特性。真空泵不斷向高速度發(fā)展，由于滑片和泵體的高速摩擦使油溫升高，油品很容易氧化分解，尤其擴(kuò)散泵往往處于很高的溫度環(huán)境下工作，使系統(tǒng)內(nèi)蒸氣壓升高，真空度降低，因此要求真空泵油具有良好的熱氧化安定性。金華隔水真空泵企業(yè)</p></p><br
