style="text-indent:25px">現在的這類冷凍油，是在不同的環(huán)境下應用到，正是因為如此，所以現在企業(yè)選用冷凍油的時候，也要考慮自身的需求如何。通過這樣的無水冷凍油，就能完成對制冷系統(tǒng)的潤滑，減少磨損，從而能延長制冷系統(tǒng)的使用壽命，延長設備的使用壽命。無水冷凍油，因為能具備很多優(yōu)勢，所以在未來的發(fā)展中，會有不錯的發(fā)展前景，能在各大行業(yè)中得到應用，成為現在人們了解和熟悉的一種潤滑油產品。也正是通過這樣的冷凍油，上海FS220R企業(yè)，才能進一步完成針對零配件的潤滑工作，能確保其中的潤滑效果，上海FS220R企業(yè)，也能成為企業(yè)熟悉的潤滑油產品，上海FS220R企業(yè)。冷凍油在壓縮機中，冷凍油主要起潤滑、密封、降溫以及能量調節(jié)四個作用。上海FS220R企業(yè)</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="上海FS220R企業(yè),冷凍油" src="https://tyunfile.71360.com/UploadFile/bingpu/637401018809058300/6262749.png"></div><p style="text-indent:25px">冷凍油不含水和雜質：因為水在蒸發(fā)器結冰會影響供熱效率，與制冷劑接觸會加速制冷劑分解并腐蝕設備，所以冷凍機油不能含水和雜質。冷凍機油還應有良好的抗泡性，對橡膠、漆包線等材料不溶解、不膨脹。在封閉式制冷機中使用時應有良好的電絕緣性。主要功能：(1)潤滑摩擦面，使摩擦面完全被油膜分隔開來，從而降低摩擦功、摩擦熱和磨損；(2)冷凍機油的流動帶走摩擦熱，使摩擦零件的溫度保持在允許范圍內；(3)在密封部位充滿油，保證密封性能，防止制冷劑的泄漏；(4)油的運動帶走金屬摩擦產生的磨屑，起到清洗摩擦面的作用；(5)為卸載機構提供液壓的動力。CPI1516-100生產廠家制冷設備所用冷凍油的閃點必須比排氣溫度高15~30℃以上，以免引起潤滑油的燃燒和結焦。</p><div

style="text-indent:25px">冷凍潤滑油雖然可以給制冷系統(tǒng)正常工作帶來保證，但也會引起一些問題，這主要反映在以下兩個方面。1.冷凍潤滑油的黏度對制冷系統(tǒng)的影響。黏度是冷凍潤滑油的主要性能指標之一。如果黏度高，會使摩擦功率增大，起動力矩大；黏度過低，則會降低潤滑的質量。2.冷凍潤滑油的溶解性對制冷系統(tǒng)的影響。冷凍潤滑油的溶解性是對制冷劑而言的，對不同的制冷劑，溶解性不同。R22制冷劑與冷凍潤滑油相溶程度受溫度的影響，在低溫區(qū)溫度降低到一定程度時，制冷劑和冷凍潤滑油分層流動。影響制冷劑吸放熱效果，并使冷凍潤滑油也不易被壓縮機吸回。</p><p style="text-indent:25px">對冷凍油的要求有以下幾方面:(1)凝固點冷凍油在實驗條件下冷卻到停止流動的溫度稱為凝固點。制冷設備所用冷凍油的凝固點應越低越好(如R22的壓縮機，冷凍油應在-55℃以下)，否則會影響制冷劑的流動，增加流動阻力，從而導致傳熱效果差的后果。(2)黏度冷凍油黏度油料特性中的一個重要參數，使用不同制冷劑要相應選擇不同的冷凍油。若冷凍油黏度過大，會使機械摩擦功率、摩擦熱量和啟動力矩增大。反之，若黏度過小，則會使運動件之間不能形成所需的油膜，從而無法達到應有的潤滑和冷卻效果。油溫過低或多過高都將使冷凍油惡化，同時，還經常預示預示故障的到來。</p><div

style="text-indent:25px">壓縮機冷凍油抗積炭傾向性如何對壓縮機油的可靠運行是至關重要的。在實際工業(yè)使用中，大中型壓縮機由于積炭而發(fā)生著火的事故已屢見不鮮。在油品中易形成殘?zhí)康闹饕镔|是瀝青質、膠質及多環(huán)芳烴的疊合物。潤滑油料經深度精制后均可去掉大部分以上物質。一般低粘度和深度精制的潤滑油殘?zhí)恐?低，在使用中不易積炭。因此，較優(yōu)的L-DAB壓縮機油應選用深度精制的不含殘渣（光亮油）的窄餾分基礎油。添加劑也應盡量選用無灰型添加劑?，F在國內外評定空氣壓縮機油積炭傾向性的試驗方法普遍采用潤滑油老化特性測定法（GB/T 12709）和減壓蒸餾蒸出80%后殘留物性質（GB 9168）。這兩項試驗方法的試驗條件較為苛刻，如果油品的精制深度不夠或含有殘渣油（光亮油）組分或選用有灰添加劑，都很難達到較優(yōu)標準。空調壓縮機添加冷凍油的方法一般有三種，從吸氣截止閥旁邊通孔吸入，從加油孔中加入，從曲軸箱下部加入。上海FS220R企業(yè)</p><p style="text-indent:25px">冷凍油壓力關鍵是指油壓差值，由于種種原因引起油泵不上油，就是說建立不起油壓差。上海FS220R企業(yè)</p><p style="text-indent:25px">選擇冷凍油應考慮的因素：1、粘度，壓縮機的轉速越高，使用冷凍機油的粘度應越大，實際使用中一般低速立式雙缸壓縮機可使用L-DRAl5號冷凍油，中速和高速多缸壓縮機應使用L-DRA22號或L-DRA32號冷凍油，某些高速重載壓縮機的發(fā)熱量大，油溫高，氣溫也高，較好使用L-DRA46號或L-DJRA68號冷凍油。2、熱穩(wěn)定性，熱穩(wěn)定性一般用冷凍機油的閃點來衡量。閃點是指冷凍機油的蒸汽遇火后發(fā)生閃火的溫度。冷凍機油的閃點必須高于壓縮機的排氣溫度，如R717，R12，R22壓縮機使用的冷凍機油閃點應在160℃以上。上海FS220R企業(yè)</p><p
