號潤滑油主要用于氨和二氧化碳制冷劑、轉速低、負荷小的活塞式制冷壓縮機。選擇黏度還應考慮到制冷劑的種類，杭州漢鐘冷凍油價錢、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，杭州漢鐘冷凍油價錢，長期不換油，杭州漢鐘冷凍油價錢，所以一定要抗氧化安定性好的油。冷凍油可減少制冷劑在壓縮過程中由高壓側向低壓側的泄漏及減少相互間的機械摩損。杭州漢鐘冷凍油價錢</p><div

style="text-indent:25px">冷凍油用于冷水機設備制冷壓縮機內各運動部件潤滑的油稱為冷凍油。在壓縮機中，冷凍油主要起潤滑、密封、降溫及能量調節(jié)等功能。不同的冷水機運行的時候，需要使用的冷凍油指標不同，因此在選擇的時候要按照不同類型來選擇冷凍油。根據(jù)壓縮類型選用潤滑油：冷凍機組的壓縮機有活塞式、螺桿式和離心式三種，前兩種的潤滑油與被壓縮的制冷劑直接接觸，要考慮到潤滑油和制冷劑之間的相互影響問題。離心式所用的潤滑油只是用來潤滑轉子軸承，也可根據(jù)負荷及轉速的大小選用。根據(jù)制冷劑的蒸發(fā)溫度選用潤滑油：一般來說，制冷劑蒸發(fā)溫度低的冷凍機，應選用凝點低的冷凍機油，以免被制冷劑攜帶到制冷系統(tǒng)中的潤滑油凝結在節(jié)流閥和蒸發(fā)器上，影響制冷效率。用氨作制冷劑的冷凍機，所用潤滑油的凝點應低于蒸發(fā)溫度。用氟里昂作制冷劑的，潤滑油的凝點可稍高于蒸發(fā)溫度。蘇州CPI冷凍油哪家好如果冷凍油油溫一直不穩(wěn)定且緩慢上升，則說明有故障。</p><div

style="text-indent:25px">將系統(tǒng)制冷劑回收至冷凝器側，排出壓縮機中的制冷劑，并從壓縮機的排油角閥排出冷凍油。壓縮機的冷凍油從濾油器上的放油閥排出。當潤滑油為接近放完，時，從壓縮機高壓端的檢測接頭加入一定量的氮氣，使?jié)櫥蛶杭铀倥懦?，停止噴射壓力，關閉放油閥。然后拆下壓縮機的濾油器，放出油箱中的所有潤滑油，然后清洗并緊固濾油器。根據(jù)壓縮機的標準量添加潤滑油。同時，系統(tǒng)被抽空。建議選擇高(低)壓側角閥或其他相對高點作為真空泵的觸點，以防止泵送冷凍油損壞真空泵。當進行真空保壓或檢漏時，觀察壓力是否反彈。注入潤滑油，用干凈的塑料管連接到放油閥上，塑料管的另一端放入油桶中(塑料管放在油桶的底部)。注油時，油桶應關閉，以減少空氣對油的污染。定期檢查或更換冷凍機油：首先次調試1000小時后，檢查并更換冷凍機油，清洗濾油器。如果系統(tǒng)干凈，每10000小時可以更換一次。</p><p 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。冷凍油在壓縮機中，冷凍油主要起潤滑、密封、降溫及能量調節(jié)等功能。</p><div

style="text-indent:25px">可以根據(jù)一下幾個方面選擇冷凍機油：1、根據(jù)壓縮類型選用潤滑油，冷凍機的壓縮機有活塞式、螺桿式和離心式三種，前兩種的潤滑油與被壓縮的制冷劑直接接觸，要考慮到潤滑油和制冷劑之間的相互影響問題。離心式所用的潤滑油只是用來潤滑轉子軸承，也可根據(jù)負荷及轉速的大小選用。2、根據(jù)制冷劑的類型選用潤滑油，與制冷劑直接接觸的潤滑油，要考慮二者之間的相互影響。如氟里昂一類的制冷劑能溶于礦物油，因而選用的潤滑油粘度等級，應比使用不溶性制冷劑的高一個等級，以防止?jié)櫥捅幌♂尯蟛荒鼙ＷC潤滑。另外，還應注意混入制冷劑中的少量潤滑油會不會影響制冷系統(tǒng)的工作。冷凍機油的絮凝點便是檢查混入制冷劑中的潤滑油是否析出蠟結晶而使制冷系統(tǒng)堵塞的質量指標。POE冷凍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。杭州漢鐘冷凍油價錢</p><p style="text-indent:25px">冷凍油油壓大小依據(jù)壓縮機的結構而定。杭州漢鐘冷凍油價錢</p><p style="text-indent:25px">對現(xiàn)在企業(yè)而言，冷凍油選擇要考慮的則是現(xiàn)在冷凍油本身是否適合使用，因為現(xiàn)在冷凍油會有不同的型號和參數(shù)，在其中性能上就有差別，因此會應用在不同的領域中，所以說，現(xiàn)在這樣的潤滑油產品，是否能適合自身使用需要，是關鍵的。應該考慮到的，則是現(xiàn)在企業(yè)對冷凍油還有哪些要求，像是冷凍油自身的耐低溫能力，還有就是粘度，閃點等，這些都應該考慮到。因此現(xiàn)在企業(yè)，在對冷凍油選用的時候，不僅是需要考慮到上述講到的質量指標的問題，而且還要從多個方面進行考慮，無論是品質，還是是否適合等，這些都應該考慮到。只有經過多個方面的考慮，才能從中選擇適合的冷凍油，滿足企業(yè)的使用需要。杭州漢鐘冷凍油價錢</p><p
