style="text-indent:25px">冷凍油是機械工業(yè)常用產(chǎn)品，加工工藝不太復雜，原料易得，因此，生產(chǎn)廠家很多，由此帶來的質(zhì)量問題自然不可避免，冷凍油供應。再加上市場上的壓縮機售后隊伍特別多，壓縮機油的來源就更不好把握。一般壓縮機設備上注明：壓縮機油要使用原廠家提供的壓縮機油，如果因不使用原廠家壓縮機油而出現(xiàn)的一切不良后果自負。我們在檢修過程中，曾發(fā)現(xiàn)一起主機報燒的事故，其主要原因就是使用了劣質(zhì)的壓縮機油所致，冷凍油供應。原來，在維護期內(nèi)，該用戶更換售后服務對象，暗中與廠家以外的售后服務隊伍聯(lián)系，在換油不到半年的時間，使主機報廢，造成公司停產(chǎn)20多天，損失很大，冷凍油供應。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。冷凍油供應</p><div

style="text-indent:25px">冷凍潤滑油雖然可以給制冷系統(tǒng)正常工作帶來保證，但也會引起一些問題，這主要反映在以下兩個方面。1.冷凍潤滑油的黏度對制冷系統(tǒng)的影響。黏度是冷凍潤滑油的主要性能指標之一。如果黏度高，會使摩擦功率增大，起動力矩大；黏度過低，則會降低潤滑的質(zhì)量。2.冷凍潤滑油的溶解性對制冷系統(tǒng)的影響。冷凍潤滑油的溶解性是對制冷劑而言的，對不同的制冷劑，溶解性不同。R22制冷劑與冷凍潤滑油相溶程度受溫度的影響，在低溫區(qū)溫度降低到一定程度時，制冷劑和冷凍潤滑油分層流動。影響制冷劑吸放熱效果，并使冷凍潤滑油也不易被壓縮機吸回。冷凍油供應若冷凍油黏度過大，會使機械摩擦功率、摩擦熱量和啟動力矩增大。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="冷凍油供應,冷凍油" src="https://tyunfile.71360.com/UploadFile/bingpu/637401018809058300/6262749.png"></div><p style="text-indent:25px">在這個**都在使用機械裝備的社會下肯定是需要一種物質(zhì)維持的，無水冷凍油是很好的選擇，那么需要這樣的冷凍油的人越來越多，因為機械想很長時間的使用是需要好的機油來給進行保養(yǎng)和修復的，我們不會只使用不維護。這樣會很快的使用壞機械浪費不必要的錢，所以大家要用更好的機油前來維護。無水冷凍油，的確是成為一種新型的產(chǎn)品，尤其是在成分上，是不會含有任何水分的，因此現(xiàn)在各大企業(yè)，會這樣的無水冷凍油還是比較關注的?，F(xiàn)在針對無水冷凍油進行了解，就會看到，這樣的冷凍油液會有不同的性能，因此企業(yè)在選擇的時候，一定要考慮到其中冷凍油的性能如何，尤其是這樣冷凍油是否有很好的耐低溫能力，在低溫的條件下，是否有好的流動性，這是值得關注的一點。</p><p style="text-indent:25px">箱式冷凍機的主要作用是給設備提供工藝冷凍水，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構，這種我們稱之為箱式冷凍機。冷凍油起到了密封、冷卻、降噪等作用。</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制冷劑的排氣溫度高，希望潤滑油的粘度不應過小。又由于低壓側吸入的低溫氣體，此時潤滑油的粘度又不應過大。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。如氨和潤滑油不相溶，應選用較低粘度的潤滑油。油溫過低或多過高都將使冷凍油惡化，同時，還經(jīng)常預示預示故障的到來。冷凍油供應</p><p style="text-indent:25px">冷凍油在壓縮機中，冷凍油主要起潤滑、密封、降溫以及能量調(diào)節(jié)四個作用。冷凍油供應</p><p style="text-indent:25px">壓縮機冷凍油抗積炭傾向性如何對壓縮機油的可靠運行是至關重要的。在實際工業(yè)使用中，大中型壓縮機由于積炭而發(fā)生著火的事故已屢見不鮮。在油品中易形成殘?zhí)康闹饕镔|(zhì)是瀝青質(zhì)、膠質(zhì)及多環(huán)芳烴的疊合物。潤滑油料經(jīng)深度精制后均可去掉大部分以上物質(zhì)。一般低粘度和深度精制的潤滑油殘?zhí)恐?低，在使用中不易積炭。因此，較優(yōu)的L-DAB壓縮機油應選用深度精制的不含殘渣（光亮油）的窄餾分基礎油。添加劑也應盡量選用無灰型添加劑?，F(xiàn)在國內(nèi)外評定空氣壓縮機油積炭傾向性的試驗方法普遍采用潤滑油老化特性測定法（GB/T 12709）和減壓蒸餾蒸出80%后殘留物性質(zhì)（GB 9168）。這兩項試驗方法的試驗條件較為苛刻，如果油品的精制深度不夠或含有殘渣油（光亮油）組分或選用有灰添加劑，都很難達到較優(yōu)標準。冷凍油供應</p><p
