style="text-indent:25px">選擇冷凍油黏度時要考慮到制冷壓縮機的負荷及轉(zhuǎn)速。負荷大、轉(zhuǎn)速高的選用黏度高的油，反之，負荷小、轉(zhuǎn)速低的制冷壓縮機則選用黏度較低的潤滑油。如 13 號潤滑油主要用于氨和二氧化碳制冷劑、轉(zhuǎn)速低、負荷小的活塞式制冷壓縮機。選擇黏度還應(yīng)考慮到制冷劑的種類、軸與軸承、活塞環(huán)與汽缸間隙以及排氣溫度等。間隙大或排氣溫度高的要用黏度較高的油；氟利昂制冷壓縮機用的潤滑油黏度要比氨制冷壓縮機的潤滑油黏度高。主要是考慮排氣溫度和制冷壓縮機的密封程度。尤其是全封閉式制冷壓縮機中的潤滑油所處的工作環(huán)境要求的條件較高，長期不換油，所以一定要抗氧化安定性好的油。蘇州冰熊冷凍油報價潤滑油的酸化，會直接腐蝕設(shè)備，影響壓縮機電機壽命，建議大家要定期檢測冷凍油的ph值。</p><div

style="text-indent:25px">空調(diào)壓縮機添加冷凍油具體操作步驟如下：1、關(guān)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(guān)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(nèi)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(nèi)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(zhuǎn)2~3分鐘，使曲軸箱內(nèi)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(nèi)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。</p><p style="text-indent:25px">冷凍油的主要功能：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(nèi)；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(chǎn)生的磨屑，起到清洗摩擦面的作用；5、為卸載機構(gòu)提供液壓的動力。冷凍機油的分類：一類是傳統(tǒng)的礦物油;另一類是合成的多元醇酯類油如POE(PolyolEster)，常稱聚酯油PAG(PolyalkyleneGlyco1)也是合成的聚(乙)二醇類潤滑油，它們中文名不十分統(tǒng)一。POE油不僅能良好地用于HFC類制冷劑系統(tǒng)中，也能用于烴類制冷劑。PAG油則可用于HFC類、烴類及氨作為制冷劑的系統(tǒng)中。新購置的壓縮機冷凍油壓差值偏高以便加大潤滑油量，較好完成運動部件的磨合期，延長機器的使用壽命。</p><div

style="text-indent:25px">冷凍油有合適的粘度，冷凍機油的粘度除了要保證各運動部件的磨擦面有良好潤滑性以外，還要從制冷機中帶走部分熱量，以及起到密封作用。如果制冷機所使用的制冷劑對冷凍機油互溶性較大時，應(yīng)考慮使用粘度較大的油品，以克服潤滑油被制冷劑稀釋后的影響。較低的傾點、絮凝點，由于制冷機的工作溫度變化范圍較大，如氨制冷劑在壓縮時可高至160℃，而膨脹又下降至-10℃。因此冷凍機油的傾點要低，一般約低于冷凍溫度10℃，而且油的粘溫特性要好。以保證冷凍機油在低溫下能從蒸發(fā)器返回壓縮機。絮凝點也是檢驗冷凍機油與制冷劑混合液在一定溫度下析出石蠟可能沉淀出不溶性極性物質(zhì)的一種使用性能指標，冷凍機油的絮凝點一定不能高于蒸發(fā)器的蒸發(fā)溫度?？梢哉f冷水機的使用好壞，都主要集中在冷凍油的選擇及使用上及系統(tǒng)回油，冷卻的設(shè)計上。蘇州冰熊冷凍油報價</p><p

style="text-indent:25px">更換冷凍油不做內(nèi)部清理：壓縮機做泵集動作，將系統(tǒng)冷媒回收到冷凝器側(cè)（注意泵集動作較低吸氣壓力不低于0.5KG/cm2g），將壓縮機內(nèi)冷媒排除，保留些許內(nèi)部壓力作為動力源，將冷凍油從壓縮機的放油角閥排出。壓縮機放油角閥如下圖(一)所示位置。冷凍油排除干凈后，即可將此操作。說明：清結(jié)孔法蘭（蓋）與油位開關(guān)法蘭（蓋）安裝位置相同，油位開關(guān)法蘭為選配元件。角閥關(guān)閉，此時可以利用真空泵的抽吸力將新的冷凍油由導(dǎo)管從放油閥抽進壓縮機，達到標準加油量后，將放油閥關(guān)閉，繼續(xù)抽真空至標準要求，即完成換油操作。如此可以防止系統(tǒng)漏空氣造成后續(xù)的操作的困難。真空泵的接點建議選擇高（低）壓側(cè)角閥冰熊冷凍油多少錢</p><p
