style="text-indent:25px">空氣壓縮機的主要原因是什么?如何預防它?答：氧化安阻力差的空壓機冷凍油容易產生油泥和積碳，熱穩(wěn)定性差的空壓機油容易分解產生輕烴和碳塵，是空壓機油的主要原因。油品中易產生積碳的物質主要是膠質、瀝青和多環(huán)芳烴聚合物，可通過深度精制去除。因此，空壓機油一般采用低粘度、深度精制、窄餾分的無重質光亮油，即低殘?zhí)恐档挠推纷鳛榛A油，并盡量避免使用灰分添加劑。從而提高油品的氧化安性能和穩(wěn)定性。如何選擇空壓機油的粘度?答：壓縮機油粘度的選擇主要考慮排氣壓力，然后考慮壓力比和排氣溫度。江蘇復盛冷凍油如果冷凍油中的含水量超過100ppm，需要更換冷凍油。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="江蘇復盛冷凍油,冷凍油" src="https://tyunfile.71360.com/UploadFile/bingpu/637401018654409562/6386110.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。</p><p style="text-indent:25px">空調壓縮機添加冷凍油具體操作步驟如下：1、關閉吸氣截止閥，啟動壓縮機幾分鐘，將曲軸箱中制冷劑排入冷凝器，使曲軸箱成真空。停機并立即關閉排氣截止閥，慢慢旋下排氣截止閥的旁通孔螺塞，將高壓腔內剩氣放掉。旋下吸氣截止閥旁通孔螺塞，裝上錐牙接頭和銅管。2、準備好潤滑油。3、用手指撳住吸油管口，起動壓縮機將曲軸箱內空氣抽出。如果發(fā)現(xiàn)液擊現(xiàn)象，則讓壓縮機繼續(xù)運轉2~3分鐘，使曲軸箱內呈真空狀態(tài)，當撳住管口的手指感到有一股較強的吸力時即停。4、把手指撳住的管口浸入油中，浸入后即放手，油便從油管吸入曲軸管。5、觀察油面指示器，所指油面是否達到油面線為止。6、拆下銅管和接頭，旋上螺塞扳緊，啟動壓縮機讓曲軸箱內吸進的空氣抽出，當聽不到排氣聲時即扳緊排氣截止閥螺塞。7、打開吸、排氣截止閥，加油工作完成。用于制冷壓縮機內各運動部件潤滑的油，稱為冷凍油，又稱潤滑油。</p><div

style="text-indent:25px">冷凍油如果沒有匹配好，將有可能造成壓縮機燒壞，制冷系統(tǒng)癱瘓后，其影響不可估量。水冷螺桿式冷水機上使用的冷凍油應該使用原廠匹配的產品。較優(yōu)合適的冷凍油能夠讓螺桿壓縮機的制冷量更高，隨之其效率高。螺桿式冷水機的應用千變萬化，也就是壓縮機的工況變化繁多，并且不同工質系統(tǒng)的回油情況不一樣，所以油的選擇也比較復雜。一般來講，R22為表示的工質，選用礦物油居多，而以R404A和R134a為表示的工質，則選擇合成油。大的類型選定后，還要根據(jù)不同的工況選擇不同牌號的油。螺桿機在運轉過程中不會產生摩擦，這個理論是在正確使用相關冷凍油的情況下成立的。江蘇復盛冷凍油</p><p style="text-indent:25px">冷凍油滲入各摩擦件密封面而形成油封，起到阻止制冷劑泄漏的作用。江蘇復盛冷凍油</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。江蘇復盛冷凍油</p><p
