style="text-indent:25px">如果冷凍油不匹配，可能會(huì)導(dǎo)致壓縮機(jī)燒毀。制冷系統(tǒng)發(fā)生故障后，其影響是不可估量的。建議螺桿式壓縮機(jī)使用的冷凍機(jī)油應(yīng)與原產(chǎn)品相匹配。較優(yōu)合適的冷凍機(jī)油可以使螺桿式壓縮機(jī)的制冷量更高，進(jìn)而效率更高。螺桿機(jī)的應(yīng)用是千變?nèi)f化的，即壓縮機(jī)的工況千差萬(wàn)別，不同工質(zhì)系統(tǒng)的回油情況也不同，所以選油也比較復(fù)雜。一般來(lái)說(shuō)，以R22為表示的工質(zhì)是礦物油，以R404A和R134a為表示的工質(zhì)是合成油。選擇大型號(hào)后，應(yīng)根據(jù)不同的工況選擇不同品牌的油。</p><p style="text-indent:25px">壓縮機(jī)的冷凍油更換周期：一般每運(yùn)轉(zhuǎn)10000小時(shí)須檢查或更換一次潤(rùn)滑油，且首先次運(yùn)轉(zhuǎn)后，2500小時(shí)建議更換一次潤(rùn)滑油并清洗機(jī)油過(guò)濾器。因系統(tǒng)組裝的殘?jiān)谡竭\(yùn)轉(zhuǎn)后都會(huì)累積至壓縮機(jī)中。所以2500小時(shí) (或3個(gè)月) 應(yīng)更換一次潤(rùn)滑油，爾后再依系統(tǒng)清潔度狀態(tài)定時(shí)更換，若系統(tǒng)清潔度佳，可每10000小時(shí) (或每年) 更換一次。壓縮機(jī)排氣溫度若長(zhǎng)期維持在高溫狀態(tài)，則潤(rùn)滑油劣化進(jìn)度很快，需要定期（每2 個(gè)月）檢查潤(rùn)滑油化學(xué)特性，不合格時(shí)即更換。更換冷凍油并作內(nèi)部清理：冷凍油排除干凈且壓縮機(jī)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(jī)油過(guò)濾器接頭和清結(jié)孔法蘭（或油位開(kāi)關(guān)法蘭）后，將壓縮機(jī)油槽內(nèi)的污染物去除干凈，并檢查機(jī)油過(guò)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(jī)油過(guò)濾器，注意換新時(shí)過(guò)濾器接口螺母要旋緊，做好密封，防止內(nèi)漏；機(jī)油過(guò)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。冷凍油可以冷卻被壓縮的制冷劑。</p><div

style="text-indent:25px">冷凍機(jī)油主要用于潤(rùn)滑冷凍機(jī)中需要潤(rùn)滑的部位，與壓縮機(jī)運(yùn)轉(zhuǎn)性能和使用壽命有密切關(guān)系，所以它的選擇和應(yīng)用，都是非常的重要。冷凍機(jī)按其結(jié)構(gòu)可分為活塞式(或往復(fù)式)、回轉(zhuǎn)式(包括螺桿式、轉(zhuǎn)子式及滑片式等)以及離心式(或透平式)等3類。在活塞式制冷機(jī)中需要潤(rùn)滑的部位有活塞與汽缸壁、連桿軸瓦與活塞銷或曲柄銷、主軸頸與前后軸承軸瓦、曲軸箱、軸封及閥門等。而螺桿式制冷機(jī)中需要潤(rùn)滑的部位則有凸凹螺桿的轉(zhuǎn)動(dòng)嚙合部分、螺桿前后的滑動(dòng)軸承、主動(dòng)螺桿的平衡活塞等。離心式制冷機(jī)中需要潤(rùn)滑的部位有增速齒輪、主軸承、軸端密封面等。由于活塞往復(fù)運(yùn)動(dòng)可能有部分冷凍油進(jìn)入氣缸并隨高速氣體帶入系統(tǒng)中，同時(shí)由于潤(rùn)滑油蒸發(fā)也可能進(jìn)入系統(tǒng)中與制冷劑混合，混合后的潤(rùn)滑油經(jīng)過(guò)分離器大部分可以分離，也有少量仍隨制冷劑進(jìn)入冷卻器等設(shè)備內(nèi)。溫度降低，潤(rùn)滑油冷凝，附著在冷卻器和系統(tǒng)的管壁形成油膜，使傳熱效果降低，冷藏室的溫度增高。另一方面，高壓制冷劑氣體也可能滲漏到潤(rùn)滑油中，使?jié)櫥拖♂?。冷凍油是螺桿式冷水機(jī)運(yùn)行不可缺少的重要輔助材料。江蘇CPI冷凍油供應(yīng)</p><p

style="text-indent:25px">活塞式制冷壓縮機(jī)曲軸磨損的原因可能有油品、機(jī)械、操作管理等方面，當(dāng)然需要具體情況具體分析。其中冷凍油的質(zhì)量好壞是影響曲軸磨損的主要原因之一?；钊街评鋲嚎s機(jī)轉(zhuǎn)速高、負(fù)荷大、排氣溫度高，如果油品的粘度過(guò)低或潤(rùn)滑油清潔度不高,都會(huì)使曲軸發(fā)生異常的磨損乃至損壞。此外操作過(guò)程中發(fā)生油品混合，進(jìn)入曲軸箱的液體制冷劑與冷凍機(jī)油混合并起泡沫導(dǎo)致各摩擦部位的潤(rùn)滑效果下降，從而加劇磨損。另外軸瓦和連桿瓦是由巴氏合金制成的，如果冷凍機(jī)油中含有其磨損的金屬顆粒，會(huì)使曲軸的磨損加劇。以上這些屬于基本常見(jiàn)的情況，只要注意避免，就可延長(zhǎng)制冷壓縮機(jī)的使用壽命。上海CPI冷凍油價(jià)格</p><p
