style="text-indent:25px">防銹性好壓縮機的冷凍油油冷卻等部件的材質(zhì)為銅或銅金屬，易被腐蝕，會使油品出現(xiàn)早期氧化變化變質(zhì)，生成油泥。這就要求油品應(yīng)有良好的抗腐蝕能力。空氣中的水分易在間歇操作的壓縮機氣缸內(nèi)冷卻，這對潤滑不利并能產(chǎn)生磨損和銹蝕，要求壓縮機油應(yīng)具有良好的防銹蝕作用。壓縮機在運行中不斷與空氣中的冷凝水相遇并被劇烈攪拌，易產(chǎn)生乳化現(xiàn)象，造成油氣分離不清，油耗增大。由于油被乳化而使油膜破壞，造成磨損。乳化的油會促使灰塵、砂礫和污泥分散，影響閥的功能，增加摩擦、磨損和氧化。因此，較優(yōu)壓縮機油均具有好的抗乳化性能和油水分離性能。</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，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，因為只有擁有好的品質(zhì)，才能確保其中的性能，所以這一點很重要，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。如果檢測出，每100ml的冷凍油中的污染物超過5mg，則建議對之進行更換。</p><div

style="text-indent:25px">在更換螺桿壓縮機冷凍時，分為兩種情況。首先，更換冷凍油不做內(nèi)部清理。壓縮機做泵集動作，將系統(tǒng)冷媒回收到冷凝器側(cè)(注意泵集動作較低吸氣壓力不低于0.5Kg/cm2G)，將壓縮機內(nèi)冷媒排除，保留些許內(nèi)部壓力作為動力源，將冷凍油從壓縮機的放油角閥排出。第二種，更換冷凍油并作內(nèi)部清理，放油的動作如前所述，冷凍油排除干凈且壓縮機內(nèi)外壓力平衡后，用內(nèi)六角扳手將法蘭螺栓松脫，拆出機油過濾器接頭和清結(jié)孔法蘭(或油位開關(guān)法蘭)后，將冷水機的壓縮機油槽內(nèi)的污染物去除干凈，并檢查機油過濾器孔網(wǎng)是否有破損，并將其上的油泥、污染物等吹除，或更換新的機油過濾器，注意換新時過濾器接口螺母要旋緊，做好密封，防止內(nèi)漏;機油過濾器接頭內(nèi)襯墊一定要換新，防止內(nèi)漏;其他法蘭襯墊也建議更新。大的類型選定后，還要根據(jù)不同的工況選擇不同牌號的油。約克冷凍油供應(yīng)</p><p style="text-indent:25px">冷凍油不斷沖洗摩擦表面，帶走磨屑，可減少摩擦件的磨損。約克冷凍油供應(yīng)</p><p style="text-indent:25px">冷凍油如果沒有匹配好，將有可能造成壓縮機燒壞，制冷系統(tǒng)癱瘓后，其影響不可估量。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。較優(yōu)合適的冷凍油能夠讓螺桿壓縮機的制冷量更高，隨之其效率高。螺桿式冷水機的應(yīng)用千變?nèi)f化，也就是壓縮機的工況變化繁多，并且不同工質(zhì)系統(tǒng)的回油情況不一樣，所以油的選擇也比較復(fù)雜。一般來講，R22為表示的工質(zhì)，選用礦物油居多，而以R404A和R134a為表示的工質(zhì)，則選擇合成油。大的類型選定后，還要根據(jù)不同的工況選擇不同牌號的油。約克冷凍油供應(yīng)</p><p
