style="text-indent:25px">冷凍油在壓縮機(jī)運(yùn)轉(zhuǎn)時(shí)的摩擦面起什么作用?1、冷凍機(jī)油在磨合表面間形成-層油膜，降低了運(yùn)動(dòng)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(jī)的耐久性。2、冷凍機(jī)油在油泵的壓送下，使冷凍機(jī)油在磨合面之間成為流動(dòng)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(jī)油在活塞與汽缸壁面之間，不僅可以潤(rùn)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(jī)的輸氣系數(shù)(容積效率)。4、在磨合面循環(huán)流動(dòng)的冷凍機(jī)油不斷地把磨屑帶走，改善了磨合面的工作情況。上海約克K油管道冷凍油起到了密封、冷卻、降噪等作用。</p><div

style="text-indent:25px">冷凍油變質(zhì)的主要原因：1、混入水分，由于制冷系統(tǒng)中滲入空氣，空氣中的水分與冷凍機(jī)油接觸后混合進(jìn)去；制冷劑中含水量較多時(shí)，也會(huì)使水分混入冷凍機(jī)油。冷凍機(jī)油中混入水分后，粘度降低，對(duì)金屬造成腐蝕。在氟利昂制冷系統(tǒng)中，還會(huì)引起“冰塞”現(xiàn)象；2、氧化，冷凍機(jī)油在使用過(guò)程中，當(dāng)壓縮機(jī)的排氣溫度較高時(shí)，就有可能引起氧化變質(zhì)，特別是化學(xué)穩(wěn)定性差的冷凍機(jī)油，更易變質(zhì)，經(jīng)過(guò)一段時(shí)間，冷凍機(jī)油中會(huì)形成殘?jiān)?，使軸承等處的潤(rùn)滑變壞。有機(jī)填料、機(jī)械雜質(zhì)等混入冷凍機(jī)油中也會(huì)加速它的老化或氧化；</p><p style="text-indent:25px">在壓縮機(jī)中，冷凍油主要起潤(rùn)滑、密封、降溫以及能量調(diào)節(jié)四個(gè)作用。(1)潤(rùn)滑冷凍油在壓縮機(jī)運(yùn)轉(zhuǎn)中起潤(rùn)滑作用，以減少壓縮機(jī)運(yùn)行摩擦和磨損程度，從而延長(zhǎng)壓縮機(jī)的使用壽命。(2)密封冷凍油在壓縮機(jī)中起密封作用，使壓縮機(jī)內(nèi)活塞與汽缸面之間、各轉(zhuǎn)動(dòng)的軸承之間達(dá)到密封的作用，以防止制冷劑泄漏。(3)降溫冷凍油在壓縮機(jī)各運(yùn)動(dòng)部件間潤(rùn)滑時(shí)，可帶走工作過(guò)程中所產(chǎn)生的熱量，使各運(yùn)動(dòng)部件保持較低的溫度，從而提高壓縮機(jī)的效率和使用的可靠性。(4)能量調(diào)節(jié) 對(duì)于帶有能量調(diào)節(jié)機(jī)構(gòu)的制冷壓縮機(jī)，可利用冷凍油的油壓作為能量調(diào)節(jié)機(jī)械的動(dòng)力。若冷凍油黏度過(guò)大，會(huì)使機(jī)械摩擦功率、摩擦熱量和啟動(dòng)力矩增大。</p><div style="width:100%;text-align: center;"><img

style="text-indent:25px">冷凍油應(yīng)有良好的低溫下的流動(dòng)性，在蒸發(fā)器內(nèi)，因溫度低、油的粘度增大，流動(dòng)性變差，當(dāng)達(dá)到一定溫度時(shí)冷凍機(jī)油停止流動(dòng)，此時(shí)的溫度稱油的凝固點(diǎn)。制冷機(jī)的冷凍機(jī)油要求凝固點(diǎn)要低，特別是低溫制冷機(jī)對(duì)油的凝固點(diǎn)要求很重要。否則流動(dòng)性降低，既影響蒸發(fā)器的傳熱又影響機(jī)器的潤(rùn)滑。各種冷凍油的凝固點(diǎn)都在-40℃以下，能夠滿足一般用途的制冷機(jī)的使用需要。蒸發(fā)溫度再低時(shí)，可使用精密儀器油，其凝固點(diǎn)一般不高于-60℃。各種制冷劑與冷凍機(jī)油相溶是不相同的，大致分三大類：一類為相互不溶解的，一類為相互無(wú)限溶解的，再一類是介于上述二者中間的。關(guān)于溶解性的利弊在制冷劑一節(jié)已有論述，這里不再重復(fù)。冷凍油油壓大小依據(jù)壓縮機(jī)的結(jié)構(gòu)而定。上海約克K油管道</p><p
