style="text-indent:25px">離心機的離心原理：當(dāng)含有細小顆粒的懸浮液靜置不動時，由于重力場的作用使得懸浮的顆粒逐漸下沉。粒子越重，下沉越快，反之密度比液體小的粒子就會上浮。微粒在重力場下移動的速度與微粒的大小、形態(tài)和密度有關(guān)，并且又與重力場的強度及液體的粘度有關(guān)。象紅血球大小的顆粒，直徑為數(shù)微米，就可以在通常重力作用下觀察到它們的沉降過程。此外，物質(zhì)在介質(zhì)中沉降時還伴隨有擴散現(xiàn)象。擴散是無條件的確定的。擴散與物質(zhì)的質(zhì)量成反比，顆粒越小擴散越嚴(yán)重。而沉降是相對的，有條件的，要受到外力才能運動。沉降與物體重量成正比，顆粒越大沉降越快。對小于幾微米的微粒如病du或蛋白質(zhì)等，它們在溶液中成膠體或半膠體狀態(tài)，**利用重力是不可能觀察到沉降過程的。因為顆粒越小沉降越慢，而擴散現(xiàn)象則越嚴(yán)重。所以需要利用離心機產(chǎn)生強大的離心力，才能迫使這些微?？朔U散產(chǎn)生沉降運動。山西平板式離心機離心機要正確操作和做好日常維護工作。</p><div

style="text-indent:25px">三足式離心機選型的原則：1、固相濃度較高，固相顆粒是剛體或晶體，且粒徑較大，則可選用離心過濾機。要是顆粒容許被破裂，則可選用三足式離心機，顆粒不容許被破裂則可選用活塞推料或離心力卸料三足式離心機，脫水性能除與物料自己的吸水性能有關(guān)外，還與三足式離心機的分離因素、分離時間、濾網(wǎng)的孔徑、孔隙率等參數(shù)，以及三足式離心機材料、溶液PH值、顆粒特性和工藝要求等有關(guān)。2、固相濃度較低，顆粒粒徑很細，或是無定型的菌絲體，要是選用離心過濾機，由于粒徑太細，濾網(wǎng)跑料嚴(yán)峻。濾網(wǎng)太細，則脫水性能降落，無定型的菌絲體和含油的固體顆粒會把濾網(wǎng)堵去世，在此環(huán)境下，發(fā)起接納沒有濾網(wǎng)的三足式沉降三足式離心機或螺旋沉降三足式離心機，并憑據(jù)固液粒徑巨細，液固密度差，選擇符合的分散因數(shù)、長徑比、流量、轉(zhuǎn)差和溢流半徑。要是顆粒太細很不勻稱，則可先用篩分把粗顆粒撤除，然后再用三足式離心機進一步脫水。3、懸浮液中固液二相的密度差靠近，顆粒粒徑在0.05mm以上的，則可選用過濾三足式離心機。</p><p style="text-indent:25px">離心機的發(fā)展離心機是將樣品進行分離的儀器，普遍應(yīng)用于生物醫(yī)學(xué)、石油化工、農(nóng)業(yè)、食品衛(wèi)生等領(lǐng)域，它利用不同物質(zhì)在離心力場中沉淀速度的差異，實現(xiàn)樣品的分析分離。離心機自問世以來，歷經(jīng)低速、調(diào)整、超速的變遷，其進展主要體現(xiàn)在離心設(shè)備和離心技術(shù)兩方面，二者相輔相成。從轉(zhuǎn)速看，臺式離心機基本屬于低速、高速離心機的范疇，因此具有低速和高速離心機的技術(shù)特點，其結(jié)構(gòu)主要由電機驅(qū)動系統(tǒng)、制冷系統(tǒng)、機械系統(tǒng)、轉(zhuǎn)頭和系統(tǒng)控制等幾部分組成，與落地式離心機相比只不過是尺寸和容量小一點罷了。離心就是利用離心機轉(zhuǎn)子高速旋轉(zhuǎn)產(chǎn)生的強大的離心力，加快液體中顆粒的沉降速度，把樣品中不同沉降系數(shù)和浮力密度的物質(zhì)分離開。離心機電機速度過高，電路自身設(shè)計缺陷會導(dǎo)致電機溫升過大。</p><div

style="text-indent:25px">購買離心機的離心轉(zhuǎn)頭：離心機的型號確定后，就是選購什么樣的離心轉(zhuǎn)頭?？紤]的主要的根據(jù)就是樣品的容量及離心的條件。通常有水平轉(zhuǎn)頭和角轉(zhuǎn)頭各一個，或大容量（相對較低速）的轉(zhuǎn)頭和小容量高轉(zhuǎn)速的轉(zhuǎn)頭各一個即可滿足工作中的不同需要，不可追求越全越好，因為離心轉(zhuǎn)頭種類很多，許多是相似的，而超速機的轉(zhuǎn)頭價格相當(dāng)昂貴，如果全部配齊其價格要比離心機主機高出好幾倍，也沒有必要。由于轉(zhuǎn)頭轉(zhuǎn)速的不同價格相差很大。從轉(zhuǎn)速上講不宜追求越高越好，但應(yīng)有離心機允許的高轉(zhuǎn)速的轉(zhuǎn)頭，否則對離心機而言是個浪費。有兩臺離心機的單位可考慮轉(zhuǎn)頭型號互補以節(jié)省經(jīng)費。離心機的管理，從國內(nèi)多年離心機的使用情況看，各類型離心機應(yīng)由專人負責(zé)管理和維護。高、超速離心機要求定期檢查維修，使用者應(yīng)詳細記錄實驗狀態(tài)及維修情況，以保證離心機的安全使用。高、低速離心機由于操作簡單，通過閱讀說明書，訓(xùn)練離心機操作規(guī)程后可以自己使用。而超速離心機結(jié)構(gòu)復(fù)雜，工作程序也較繁瑣，使用不當(dāng)易發(fā)生事故，特別對離心轉(zhuǎn)頭更應(yīng)謹慎保養(yǎng)、使用。離心機一般處理物料為具有腐蝕性物料。山西平板式離心機</p><p style="text-indent:25px">離心機運轉(zhuǎn)前應(yīng)先切斷電源并先松開離心機剎車。山西平板式離心機</p><p style="text-indent:25px">安裝注意事項：1、有基礎(chǔ)的必須按照安裝尺寸，澆注混凝土基礎(chǔ)，三個機腳位置須校正水平，并粉光，待干燥96小時后，在三個機腳位置放置5—10mm厚的橡皮墊，使基礎(chǔ)達到減震之功用然后放置離心機，并旋緊螺母；無基礎(chǔ)的則無須混凝土澆注。2、安裝前必須謹慎保管，注意電機、電控裝置、液壓系統(tǒng)、氣控系統(tǒng)的防潮及所有易銹零部件的防銹蝕，并注意對機器外表面的保護。3、電控柜（氣控箱）應(yīng)放置在干燥、通風(fēng)和無腐蝕氣體的地點，而且應(yīng)在主機附近（可以隔離安裝）。4、離心機安裝及放置必須水平。5、機器一般為整機安裝，不得拆卸，如確有必要，則裝配后必須由制造廠技術(shù)人員對其進行確認。6、離心機在高速運轉(zhuǎn)時有輕微振動，故與離心機連接的管道（進料管、出液管、洗滌管、排氣管、在線清洗管、氮氣管、壓縮空氣管、電纜管等）必須柔性連接，連接處必須有可靠的密封或絕緣裝置。7、離心機應(yīng)有接地裝置，確保無滲漏和安全用電。山西平板式離心機</p></p><br
