style="text-indent:25px">使用真空泵時必須注意下列幾點：蒸餾系統(tǒng)和真空泵之間，必須裝有吸收裝置。蒸餾前必須用水泵徹底抽去系統(tǒng)中有機溶劑的蒸氣。如能用水泵抽氣的，則盡量用水泵，如蒸餾物質(zhì)中含有揮發(fā)性物質(zhì)，可先用水泵減壓抽降，然后改用油泵。減壓系統(tǒng)必須保持密不漏氣，所有的橡皮塞的大小和孔道要合適，橡皮管要用真空用的橡皮管。磨口玻璃涂上真空油脂。根據(jù)使用的范圍和抽氣效能可將真空泵分為三類：一般水泵，壓強可達到1.333~100kPa(10~760mmHg)為"粗"真空。油泵，壓強可達0，離心泵真空泵廠家直銷價格.133~133.3Pa(0.001~1mmHg)為"次高"真空。擴散泵，離心泵真空泵廠家直銷價格，離心泵真空泵廠家直銷價格，壓強可達0.133Pa以下，(10-3mmHg)為"高"真空。真空泵油的代用及混用原則和換油方法有哪些？離心泵真空泵廠家直銷價格</p><div

style="text-indent:25px">真空泵的抽速和真空機組的配置：不同的真空系統(tǒng)要求的真空度不同。因此往往必須由一套真空機組來完成，即由工作在不同壓力范圍的真空泵串接起來。高真空一側(cè)的真空泵能達到系統(tǒng)要求的真空度，而低真空一側(cè)的真空泵是直排大氣的。顯然簡單的真空機組就是一臺直排大氣的真空泵。但高真空系統(tǒng)一般需要三級機組，中真空一般需要二級機組?！∫慌_高真空泵和一臺低真空泵難于組成有效的高真空機組。這有幾方面的原因。流量的連續(xù)性就是其中之一。高真空泵都有前級耐壓的限制，即前級高于某一壓力，泵就不能正常工作。而當前級泵達到這一臨界壓力時，往往抽速會減小，這樣前級泵的排氣流量可能會小于主泵的排氣流量，這種流量的不一致破壞了流量連續(xù)性的要求，必然會引起真空機組不能正常工作。蒸餾真空泵定做真空泵在運轉(zhuǎn)過程中難免會出現(xiàn)磨損，磨損情況嚴重了，泵的使用性能與使用壽命也會受到影響。</p><div

style="text-indent:25px">真空泵在應(yīng)用場合的布置攻略：露天布置一般將泵集中布置在管廊下方或側(cè)面，也可以布置在被抽吸設(shè)備附近，主要優(yōu)點是通風(fēng)良好，操作和堆修方便。若泵布置在管廊下方時，泵出口中心線應(yīng)對齊，距管廊柱中心線0.6m。半露天布置的泵適用于多雨地區(qū)，一般在管廊下方布置泵，在管道上部設(shè)頂棚?；?qū)⒈貌贾迷诳蚣艿南聦拥孛嫔?，以框架平臺作為頂棚。根據(jù)泵的布置要求，將泵布置成單排、雙排或多排。室內(nèi)布置的泵適用于寒冷或多風(fēng)沙地區(qū)，以及工藝有特殊要求的場合。</p><p style="text-indent:25px">對真空泵電機溫度高的原因分析如下。(1)電機功率大，工作電流大，發(fā)熱量大。(2)風(fēng)扇轉(zhuǎn)速低，風(fēng)壓，風(fēng)量小。(3)風(fēng)扇葉片數(shù)較少，產(chǎn)生的風(fēng)量小。(4)電動機附有灰塵、油污，降低了散熱能力。(5)真空泵電機所在母線電壓為380V，由于電纜壓降及負荷分配不均，電機實際所加電壓只有365V，電壓偏低造成運行電流大。對策：電機功率、轉(zhuǎn)速是和真空泵相匹配的，不能更改。風(fēng)扇安裝于電機主軸上，電機轉(zhuǎn)速決定了風(fēng)扇轉(zhuǎn)速，也不可更換。增加風(fēng)扇葉片數(shù)量雖能起到一定作用，但葉片數(shù)量增加后，動平衡不容易找，如找正不好，會引起電機振動增加。真空泵工作時產(chǎn)生的振動對工藝過程及環(huán)境無影響。</p><div

style="text-indent:25px">抽氣量是真空泵抽速的一個衡量因素。一般單位用L/S和m3/h來表示。是彌補漏氣率的參數(shù)。不難理解，理論下抽一個相同體積的容器，為什么抽氣量大的真空泵很容易抽到我們所需的真空度，而抽氣量小的真空泵很慢甚至無法抽到我們想要的真空度? 因為管路或者容器始終不可能做到***不漏氣(公眾號:泵管家)，而抽氣量大的彌補了漏氣所帶來的真空度下降的因素，所以，大氣量的很容易抽到理想真空度值。這里建議，在計算出理論抽氣量的情況下，我們盡量選擇高一級的抽氣量的真空泵。真空泵常規(guī)的修復(fù)方法是：采用焊接。福州機械式真空泵定做</p><p

(1)同一廠家同類質(zhì)量基本相近產(chǎn)品，或高質(zhì)量泵油混入低質(zhì)量泵油仍用于原使用的機器設(shè)備。(2)同一廠家同種不同牌號產(chǎn)品在需要調(diào)整泵油的粘度等理化性能時可以混用；(3)不同類的泵油，如果知道兩種對混的泵油都是不加添加劑的，或其中一個是不加添加劑，或兩油都加添加劑但相互不起反應(yīng)的，一般可以混用，但對質(zhì)量高的泵油來說質(zhì)量會有所降低?？毡糜团c其它合成真空泵油互換時，應(yīng)將泵拆開作徹底清洗。包括各零部件均須浸漬在更換的油內(nèi)以防污染。離心泵真空泵廠家直銷價格</p><p
