style="text-indent:25px">空氣壓縮機(jī)冷凍油的功能和主要性能是什么?答：空壓機(jī)冷凍油主要用于潤滑壓縮機(jī)氣缸和排氣閥的運(yùn)動部件，起到防銹、防腐、密封和冷卻的作用。由于空壓機(jī)始終處于高壓、高溫和冷凝水的環(huán)境中，空壓機(jī)油應(yīng)具有優(yōu)良的高溫氧化安，低積碳傾向、合適的粘度和粘溫性能、良好的油水分離性、防銹性和耐腐蝕性等。合成空氣壓縮機(jī)油的主要類型是什么?與礦物油型相比有什么優(yōu)勢?答：合成壓縮機(jī)油中使用的基礎(chǔ)油主要包括合成烴(聚-烯烴)、有機(jī)酯(二酯)、聚亞烷基二醇、氟硅油和磷酸酯。與礦物油型相比，它們具有高溫穩(wěn)定性好、高溫積碳少、使用溫度寬、傾點(diǎn)低、揮發(fā)性低、使用壽命長等優(yōu)點(diǎn)。但是，由于價格高，它們只能在礦物油型壓縮機(jī)油無法承受的各種惡劣條件下使用。江蘇冰熊冷凍油一般加多少油溫過低或多過高都將使冷凍油惡化，同時，還經(jīng)常預(yù)示預(yù)示故障的到來。</p><div

style="text-indent:25px">冷凍機(jī)油的規(guī)格品種很多，為了保證制冷壓縮機(jī)的正常運(yùn)行，必須了解冷凍機(jī)油的性能，并能正確選用。冷凍機(jī)油的性能可由很多指標(biāo)來決定，以下簡要介紹其主要質(zhì)量指標(biāo)。粘度，粘度是潤滑油較重要的性能參數(shù)之一，它決定了滑動軸承中油膜的承載能力、摩擦功耗和密封面的密封能力。粘度的大小通常以運(yùn)動粘度來表示，法定單位是m2/s，常用單位是斯（st）和厘斯（cst）。1st=10-4m2/s=25px2/s，1cst=10-6m2/s=1mm2/s。制冷壓縮機(jī)的潤滑油粘度必須合適，粘度過大，油膜承載能力大，易于保持液體潤滑，但流動阻力大，壓縮機(jī)的摩擦功耗和啟動阻力將增大；粘度過小，流動阻力小、摩擦熱量少，但不易形成潤滑油膜，同時也影響密封性。由于制冷壓縮機(jī)在工作中高壓側(cè)制冷劑的排氣溫度高，希望潤滑油的粘度不應(yīng)過小。又由于低壓側(cè)吸入的低溫氣體，此時潤滑油的粘度又不應(yīng)過大。各種潤滑油的粘度都是隨溫度的升高而有不同程度的下降。在制冷壓縮機(jī)中要選用粘度隨溫度變化盡可能小的潤滑油，即**的冷凍機(jī)油。潤滑油的粘度還與制冷工質(zhì)在潤滑油中的互溶性有關(guān)。如氨和潤滑油不相溶，應(yīng)選用較低粘度的潤滑油。</p><p style="text-indent:25px">冷凍設(shè)備對冷凍油的要求：由于使用場合和制冷劑的不同，制冷設(shè)備對冷凍機(jī)油的選擇也不同。對冷凍油的要求如下：(1)冰點(diǎn)在實驗條件下，冷凍油冷卻到停止流動時的冰點(diǎn)稱為冰點(diǎn)。制冷設(shè)備中使用的冷凍油的凝固點(diǎn)應(yīng)盡可能低(如R22壓縮機(jī)，冷凍油應(yīng)低于-55)，否則會影響制冷劑的流動，增加流動阻力，導(dǎo)致傳熱效果不佳。(2)粘度冷凍機(jī)油是粘度油性質(zhì)的重要參數(shù)。應(yīng)相應(yīng)選擇不同的制冷劑。如果冷凍油的粘度過高，機(jī)械摩擦功率、摩擦熱和起動扭矩都會增加。相反，如果粘度太小，運(yùn)動部件之間不會形成所需的油膜，從而達(dá)不到潤滑和冷卻的效果。一般情況下，正常的中央空調(diào)**冷凍油是可以持續(xù)運(yùn)轉(zhuǎn)1萬小時左右。</p><div

style="text-indent:25px">如何減少工業(yè)冷水機(jī)壓縮機(jī)的冷凍油上油率：在停機(jī)時應(yīng)保證制冷劑不溶解到冷凍機(jī)油中（使用曲軸加熱器）。應(yīng)避免過濕運(yùn)轉(zhuǎn)，因為會起泡而引起的上油過多。內(nèi)部設(shè)置油分離器裝置。壓縮機(jī)內(nèi)部的油起泡使油容易被帶出壓縮機(jī)。如何保證工業(yè)冷水機(jī)適當(dāng)?shù)挠土浚汗I(yè)冷水機(jī)壓縮機(jī)在排出冷媒時，也會排出微量的冷凍機(jī)油。即使只有0.5%的上油率，如果油不能通過系統(tǒng)循環(huán)回到壓縮機(jī)中。若以5HP為例,循環(huán)量在ARI工況下約為330kg/h，則在50分鐘就可以將壓縮機(jī)內(nèi)的油全部帶出，大約在2～5小時內(nèi)壓縮機(jī)將會燒壞。為了確保工業(yè)冷水機(jī)組壓縮機(jī)運(yùn)行不缺油，應(yīng)該確保排出壓縮機(jī)的冷凍機(jī)油回到壓縮機(jī)，減少壓縮機(jī)的上油率（壓縮機(jī)頻繁啟動不利于回油）。冷凍油油溫一般要保持在45~60℃之間，較高不宜超多70℃，而且穩(wěn)定。杭州開利冷凍油工廠</p><p
