style="text-indent:25px">冷凍油的規(guī)格品種很多，為了保證制冷壓縮機的正常運行，必須了解冷凍油的性能，并能正確選用。冷凍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.噴油內(nèi)冷回轉(zhuǎn)式空氣壓縮機在工作過程中反復(fù)被加熱和冷卻。因此，要求油品粘度不應(yīng)由于溫度變化而有太大變化，應(yīng)具有良好的粘溫性能。精制的壓縮機油的粘度指數(shù)均在90以上。閃點是指油品在大氣壓力下加熱形成的蒸氣壓力，達到用明火點燃的下極限濃度時的溫度。閃點過高，油品餾分就重，粘度亦大，瀝青質(zhì)等含量就高，上海壽力斯特冷凍油**，使用時易積炭。若片面追求高閃點的壓縮機油，反而會成為不安全因素。所以，上海壽力斯特冷凍油**，壓縮機油的閃點要求適宜即可，上海壽力斯特冷凍油**。閃點只是油品使用的安全指標之一，壓縮機油閃點一般控制在200℃以上都可以安全使用。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。上海壽力斯特冷凍油**</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="上海壽力斯特冷凍油**,冷凍油"

style="text-indent:25px">冷凍油凝點和濁點的選擇：考慮的因素是蒸發(fā)溫度和制冷劑的種類。蒸發(fā)溫度低，要用凝點和濁點低的潤滑油。采用氟利昂制冷劑時，潤滑油的凝點和濁點要稍高于蒸發(fā)溫度；采用氨制冷劑時，潤滑油的凝點和濁點要低于蒸發(fā)溫度。目前國產(chǎn)的潤滑油凝點*有二種規(guī)格，即 -40℃ 和 -25℃。-25℃潤滑油可用于蒸發(fā)溫度高于 -20℃的氨制冷壓縮機和蒸發(fā)溫度低于 -20℃的氟利昂制冷壓縮機。當氨制冷壓縮機的蒸發(fā)溫度低于 -20℃時，就應(yīng)選用 -40℃的潤滑油。主要因素是排氣溫度。排氣溫度的高低，和制冷壓縮機的型式有關(guān)，并和選擇的潤滑油是否合適有關(guān)。排氣溫度高，要求潤滑油閃點也高。一般都要求排氣溫度比潤滑油的閃點低15 ～ 30℃左右。上海壽力斯特冷凍油**目前我國生產(chǎn)的冷凍油有13號、18號、25號、30號和企業(yè)標準40號五種牌號的冷凍油。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="上海壽力斯特冷凍油**,冷凍油"

style="text-indent:25px">冷凍油在壓縮機運轉(zhuǎn)時的摩擦面起什么作用?1、冷凍機油在磨合表面間形成-層油膜，降低了運動摩擦力，從而減少了摩擦耗功和熱量，較終減小了零件的磨損量，提高了壓縮機的耐久性。2、冷凍機油在油泵的壓送下，使冷凍機油在磨合面之間成為流動油膜，把摩擦熱量帶走，使摩擦表面保持在安全的溫度范圍,限制了溫度上升。3、冷凍機油在活塞與汽缸壁面之間，不*可以潤滑還起密封作用，阻止或減少了高壓蒸氣向低壓部分泄漏，提高了壓縮機的輸氣系數(shù)(容積效率)。4、在磨合面循環(huán)流動的冷凍機油不斷地把磨屑帶走，改善了磨合面的工作情況。</p><p style="text-indent:25px">在冷凍油更換時間上，一般建議螺桿壓縮機每運轉(zhuǎn)10000小時須檢查或更換一次潤滑油，且首先次運轉(zhuǎn)后，2500小時建議更換一次潤滑油并清洗或者更換機油過濾器。因系統(tǒng)組裝的殘渣在正式運轉(zhuǎn)后都會累積至壓縮機中。所以2500小時 (或3個月) 應(yīng)更換一次潤滑油，若沒有條件的至少要更換一次油過濾器芯。冷水機的壓縮機就象汽車的發(fā)動機一樣，家里的汽車多長時間檢查一次，單位的制冷系統(tǒng)的油過濾器芯也應(yīng)該更換一次。但國內(nèi)的習(xí)慣是每次開機，只要電路不壞，就一直讓風(fēng)冷螺桿式冷水機壓縮機運行，等壓縮機壞了再去維修，但殊不知更換一個小小的濾芯，能夠較大提高壓縮機的減少磨損，保持能效，提高壽命。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。</p><div

style="text-indent:25px">如果冷凍油不匹配，可能會導(dǎo)致壓縮機燒毀。制冷系統(tǒng)發(fā)生故障后，其影響是不可估量的。建議螺桿式壓縮機使用的冷凍機油應(yīng)與原產(chǎn)品相匹配。較優(yōu)合適的冷凍機油可以使螺桿式壓縮機的制冷量更高，進而效率更高。螺桿機的應(yīng)用是千變?nèi)f化的，即壓縮機的工況千差萬別，不同工質(zhì)系統(tǒng)的回油情況也不同，所以選油也比較復(fù)雜。一般來說，以R22為表示的工質(zhì)是礦物油，以R404A和R134a為表示的工質(zhì)是合成油。選擇大型號后，應(yīng)根據(jù)不同的工況選擇不同品牌的油。冷凍油的濁點是指溫度降低到某一數(shù)值時，冷凍油中開始析出石蠟，使?jié)櫥妥兊没鞚釙r的溫度。杭州約克機組冷凍油報價</p><p style="text-indent:25px">螺桿機在運轉(zhuǎn)過程中不會產(chǎn)生摩擦，這個理論是在正確使用相關(guān)冷凍油的情況下成立的。上海壽力斯特冷凍油**</p><p 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(zhuǎn)子軸承，也可根據(jù)負荷及轉(zhuǎn)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(yīng)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(yīng)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(jié)晶而使制冷系統(tǒng)堵塞的質(zhì)量指標。上海壽力斯特冷凍油**</p><p
