Glycol的縮寫，是一種合成的聚(乙)二醇類潤滑油。其中，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。PAG油則可用HFC類、烴類和氨作為制冷劑的制冷系統(tǒng)中的潤滑油。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。蘇州壽力斯特冷凍油哪家好冷凍油是螺桿壓縮機運行不可缺少的重要材料，是決定壓縮機使用壽命的關(guān)鍵。</p><div

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(chǎn)生油泥和積碳，熱穩(wěn)定性差的空壓機油容易分解產(chǎn)生輕烴和碳塵，是空壓機油的主要原因。油品中易產(chǎn)生積碳的物質(zhì)主要是膠質(zhì)、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(zhì)光亮油，即低殘?zhí)恐档挠推纷鳛榛A(chǔ)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。冷凍油能夠在螺桿與壓縮室以及陰陽螺桿間形成動態(tài)密封。</p><div

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。水冷螺桿式冷水機上使用的冷凍油應(yīng)該使用原廠匹配的產(chǎn)品。蘇州壽力斯特冷凍油哪家好</p><p

style="text-indent:25px">螺桿式冷水機的壓縮機作用就相當于人的心臟，隨著市場的發(fā)展螺桿壓縮機逐漸成為制冷壓縮機產(chǎn)品的佼佼者，在各種冷鏈、冷凍、冷庫中使用。由于螺桿壓縮機是高速旋轉(zhuǎn)的機械設(shè)備，雖然理論上來講，螺桿機在運轉(zhuǎn)過程中不會產(chǎn)生摩擦，但這個理論是在正確使用相關(guān)冷凍油的情況下成立的。另外，冷凍油還起到了密封、冷卻、降噪等作用。我們經(jīng)常會遇到壓縮機失效，所謂壓縮機失效，一般都是壓縮機螺桿咬死，軸承損壞或者電機燒毀。一般來講螺桿咬死或者軸承損壞占壓縮機失效的2/3強。前者主要是因為油的原因，后者主要是因為電的原因。因此，冷凍油是螺桿壓縮機運行不可缺少的重要材料，是決定壓縮機使用壽命的關(guān)鍵。杭州約克機組冷凍油要多少錢</p><p
