style="text-indent:25px">可以根據(jù)一下幾個方面選擇冷凍機(jī)油：1、根據(jù)壓縮類型選用潤滑油，冷凍機(jī)的壓縮機(jī)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(fù)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，杭州約克機(jī)組冷凍油工廠，杭州約克機(jī)組冷凍油工廠，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，杭州約克機(jī)組冷凍油工廠。冷凍機(jī)油的絮凝點(diǎn)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(biāo)。普遍采用的制冷壓縮機(jī)冷凍油有13號、18號和25號三種。杭州約克機(jī)組冷凍油工廠</p><div

style="text-indent:25px">為什么空氣壓縮機(jī)冷凍油必須具有良好的氧化安特性?評估方法是什么?答：空氣壓縮機(jī)油與氣缸內(nèi)的高壓熱空氣持續(xù)接觸，容易導(dǎo)致氧化和分解。在金屬磨屑的催化氧化作用下，油品老化加劇，各種有機(jī)酸、膠質(zhì)、瀝青質(zhì)等。會降低設(shè)備的機(jī)械效率，造成磨損，提高機(jī)器溫度，甚至造成氣缸事故?？諝鈮嚎s機(jī)冷凍油是如何分類的?答：根據(jù)壓縮機(jī)的結(jié)構(gòu)，空氣壓縮機(jī)油有兩種類型：型式分往復(fù)合空氣壓縮機(jī)油和旋轉(zhuǎn)空氣壓縮機(jī)油。根據(jù)基礎(chǔ)油的種類，空氣壓縮機(jī)油可分為兩類：礦物油壓縮機(jī)油和合成壓縮機(jī)油。</p><p style="text-indent:25px">現(xiàn)在的冷凍油，的確已經(jīng)在很多行業(yè)中得到應(yīng)用，在選擇的時候，企業(yè)會優(yōu)先考慮現(xiàn)在這一潤滑油的特性以及質(zhì)量指標(biāo)，但是現(xiàn)在冷凍油的選用，不應(yīng)該只是考慮其中性能如何，尤其是還需要考慮其他方面，只有這樣，才能選用到適合的冷凍油。在針對冷凍油選用的時候，首先要考慮到的就是其中冷凍油的品質(zhì)怎么樣，對現(xiàn)在企業(yè)而言，如今這一潤滑油產(chǎn)品的品質(zhì)是很重要的，因?yàn)橹挥袚碛泻玫钠焚|(zhì)，才能確保其中的性能，所以這一點(diǎn)很重要，有些廠家銷售的冷凍油，雖然在價格上比較低，但是品質(zhì)卻無法保證，因此一定要注意到這一點(diǎn)。冷凍油的濁點(diǎn)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。</p><div

style="text-indent:25px">冷凍機(jī)油的性能要求：1、合適的粘度，冷凍機(jī)油的粘度除了要保證各運(yùn)動部件的磨擦面有良好潤滑性以外，還要從制冷機(jī)中帶走部分熱量，以及起到密封作用。如果制冷機(jī)所使用的制冷劑對冷凍機(jī)油互溶性較大時，應(yīng)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。2、揮發(fā)性小，閃點(diǎn)高，冷凍機(jī)油的揮發(fā)量愈大，隨制冷劑循環(huán)的油量也愈多，因此要求冷凍機(jī)油的餾份范圍愈窄愈好，閃點(diǎn)亦應(yīng)高于制冷機(jī)排氣溫度25～30℃以上。3、良好的化學(xué)穩(wěn)定性和熱氧化穩(wěn)定性，制冷機(jī)工作中的較后壓縮溫度可達(dá)130℃～160℃，在此溫度下冷凍機(jī)油會受熱而不斷分解變質(zhì)，生成積炭而導(dǎo)致制冷機(jī)產(chǎn)生故障與磨損。冷凍油可以減少壓縮機(jī)運(yùn)行摩擦和磨損程度，從而延長壓縮機(jī)的使用壽命。杭州約克機(jī)組冷凍油工廠</p><p style="text-indent:25px">若冷凍油黏度過小，則會使運(yùn)動件之間不能形成所需的油膜，從而無法達(dá)到應(yīng)有的潤滑和冷卻效果。杭州約克機(jī)組冷凍油工廠</p><p style="text-indent:25px">壓縮機(jī)內(nèi)部冷凍油系維系壓縮機(jī)正常運(yùn)轉(zhuǎn)之關(guān)鍵，一般潤滑油的問題有：1）異物混入，致潤滑油污染，多個機(jī)油過濾器。2）高溫效應(yīng)致潤滑油降低，失去潤滑功能。3）系統(tǒng)水份污染，酸化，侵蝕電機(jī)。壓縮機(jī)冷凍油檢測和更換：對于系統(tǒng)廠商而言，壓縮機(jī)冷凍油的檢測和更換周期以及生產(chǎn)周期的生產(chǎn)過程的工藝控制有關(guān)。如果系統(tǒng)的蒸發(fā)器和冷凝器及系統(tǒng)接頭的潔凈度控制比較好，那么相對而言進(jìn)入壓縮機(jī)的相對就比較少，檢測和保養(yǎng)周期就可以相對加長。杭州約克機(jī)組冷凍油工廠</p><p
