style="text-indent:25px">一般情況下，正常的中央空調(diào)**冷凍油是可以持續(xù)運轉(zhuǎn)1萬小時左右，但是這個在相對理想的數(shù)值下面，當環(huán)境不好或者是周圍的情況惡劣的話，工作人員還是要定期使用檢測指標的工具對中央空調(diào)**冷凍油進行質(zhì)量檢測，一旦出現(xiàn)PH指標下降、污染指數(shù)上升及含水量大的情況下，需要及時更換，避免變質(zhì)的中央空調(diào)**冷凍油對壓縮機起不到保護作用，相反會阻礙它的正常運轉(zhuǎn)。另外在更換中央空調(diào)**冷凍油的過程中，建議一定要斷電操作，前面記得關(guān)機，避免更換途中電流或者機器沒有冷卻在更換機油過程中出現(xiàn)燙傷情況。杭州約克冷凍油供應(yīng)由于使用場合和制冷劑的不同，制冷設(shè)備對冷凍油的選擇也不一樣。</p><div

style="text-indent:25px">箱式冷凍機的主要作用是給設(shè)備提供工藝冷凍水，來起到制冷降溫的作用，所以冷凍油是非常重要的。1、冷卻作用。它能及時帶走運動表面摩擦產(chǎn)生的熱量，防止壓縮機溫升過高或壓縮機被燒壞。2、潤滑作用。它可以潤滑壓縮機運動零部件表面，減少阻力和摩擦，降低功耗，延長使用壽命。3、密封作用。潤滑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。4、降低壓縮機噪聲。潤滑油不斷沖洗摩擦表面，帶走磨屑，可減少摩擦件的磨損。箱式冷凍機是指冷凍機的所有部件(比如壓縮機、蒸發(fā)器、冷凝器、水泵、冷凍配件、電控系統(tǒng)等)組合成一體機后，固定在機箱內(nèi)部，等于是箱體密封式結(jié)構(gòu)，這種我們稱之為箱式冷凍機。</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">冷凍機油的規(guī)格品種很多，為了保證制冷壓縮機的正常運行，必須了解冷凍機油的性能，并能正確選用。冷凍機油的性能可由很多指標來決定，以下簡要介紹其主要質(zhì)量指標。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。在制冷壓縮機中要選用粘度隨溫度變化盡可能小的潤滑油，即**的冷凍機油。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。冷凍油在實驗條件下冷卻到停止流動的溫度稱為凝固點。杭州約克冷凍油供應(yīng)</p><p 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。江蘇壽力斯特冷凍油</p><p style="text-indent:25px">冷凍油的作用：1）在螺桿與壓縮室以及陰陽螺桿之間形成動態(tài)密封，減少制冷劑在壓縮過程中由高壓側(cè)向低壓側(cè)的泄漏。2）冷卻被壓縮的制冷劑，油被噴入壓縮機內(nèi)，吸收制冷劑氣體在壓縮過程中產(chǎn)生的熱量，降低排氣溫度。3）在軸承以及螺桿之間形成油膜支撐轉(zhuǎn)子，并開始潤滑作用。4）傳遞壓差力，驅(qū)動容量調(diào)節(jié)系統(tǒng)，通過壓縮機的加卸載電磁閥的動作，調(diào)節(jié)容調(diào)滑塊的位置，實現(xiàn)壓縮機容量調(diào)節(jié)控制。5）降低運轉(zhuǎn)噪音。冷凍油主要監(jiān)測指標：1）PH值指標：潤滑油的酸化，會直接影響壓縮機的電機壽命，故應(yīng)定期檢查潤滑油之酸度是否合格。一般潤滑油酸度低于PH6以下即須更換。若無法檢查酸度則應(yīng)定期更換系統(tǒng)之干燥過濾器，使系統(tǒng)干燥度保持在正常狀態(tài)下。2）污染度指標：如果100ml的冷凍油中分子量超過5mg，建議更換冷凍油。3）含水量：超過100ppm，需要更換冷凍油。江蘇壽力斯特冷凍油</p><p
