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。</p><p style="text-indent:25px">冷凍油是指根據(jù)冷凍機(jī)的工作特點(diǎn)和潤(rùn)滑油的具體要求而調(diào)配的潤(rùn)滑油，在制冷系統(tǒng)中的作用有以下幾個(gè)方面。1.潤(rùn)滑相互摩擦的零件表面，使摩擦表面完全被油膜分開(kāi)，降低壓縮機(jī)的摩擦功、摩擦熱和零件的磨損。2.帶走摩擦熱量，降低壓縮機(jī)摩擦部件的表面溫度，使摩擦零件的溫度保持在允許范圍內(nèi)。3.使活塞環(huán)與汽缸鏡面間、軸封摩擦面等處密封部分充滿(mǎn)潤(rùn)滑油.以阻擋制冷劑的泄漏。4.帶走金屬摩擦表面產(chǎn)生的磨屑。R12等制冷劑與冷凍潤(rùn)滑油可以互溶，但由于冷凍潤(rùn)滑油是一種高溫蒸發(fā)的液體，制冷劑中溶油量多，會(huì)使制冷劑在定壓下沸點(diǎn)升高，降**冷量；同時(shí)，冷凍潤(rùn)滑油中的制冷劑過(guò)多，也會(huì)稀釋冷凍油，降低冷凍潤(rùn)滑油的黏度。冷凍油在實(shí)驗(yàn)條件下冷卻到停止流動(dòng)的溫度稱(chēng)為凝固點(diǎn)。</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(dòng)部件的磨擦面有良好潤(rùn)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(duì)冷凍機(jī)油互溶性較大時(shí)，應(yīng)考慮使用粘度較大的油品，以克服潤(rùn)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(huì)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。上海壽力斯特冷凍油價(jià)格</p><p
