冷凍油在實(shí)驗(yàn)條件下冷卻到停止流動(dòng)的溫度稱為凝固點(diǎn)。制冷設(shè)備所用冷凍油的凝固點(diǎn)應(yīng)越低越好(如R22的壓縮機(jī)，冷凍油應(yīng)在-55℃以下)，否則會(huì)影響制冷劑的流動(dòng)，增加流動(dòng)阻力，從而導(dǎo)致傳熱效果差的后果。(2)黏度冷凍油黏度油料特性中的一個(gè)重要參數(shù)，使用不同制冷劑要相應(yīng)選擇不同的冷凍油。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。反之，若黏度過(guò)小，則會(huì)使運(yùn)動(dòng)件之間不能形成所需的油膜，從而無(wú)法達(dá)到應(yīng)有的潤(rùn)滑和冷卻效果。冷凍油在實(shí)驗(yàn)條件下冷卻到停止流動(dòng)的溫度稱為凝固點(diǎn)。上海比澤爾冷凍油</p><p

style="text-indent:25px">冷凍潤(rùn)滑油雖然可以給制冷系統(tǒng)正常工作帶來(lái)保證，但也會(huì)引起一些問(wèn)題，這主要反映在以下兩個(gè)方面。1.冷凍潤(rùn)滑油的黏度對(duì)制冷系統(tǒng)的影響。黏度是冷凍潤(rùn)滑油的主要性能指標(biāo)之一。如果黏度高，會(huì)使摩擦功率增大，起動(dòng)力矩大；黏度過(guò)低，則會(huì)降低潤(rùn)滑的質(zhì)量。2.冷凍潤(rùn)滑油的溶解性對(duì)制冷系統(tǒng)的影響。冷凍潤(rùn)滑油的溶解性是對(duì)制冷劑而言的，對(duì)不同的制冷劑，溶解性不同。R22制冷劑與冷凍潤(rùn)滑油相溶程度受溫度的影響，在低溫區(qū)溫度降低到一定程度時(shí)，制冷劑和冷凍潤(rùn)滑油分層流動(dòng)。影響制冷劑吸放熱效果，并使冷凍潤(rùn)滑油也不易被壓縮機(jī)吸回。比澤爾320SH供應(yīng)</p><p
