style="text-indent:25px">將系統(tǒng)制冷劑回收至冷凝器側(cè)，排出壓縮機(jī)中的制冷劑，并從壓縮機(jī)的排油角閥排出冷凍油。壓縮機(jī)的冷凍油從濾油器上的放油閥排出。當(dāng)潤(rùn)滑油為接近放完，時(shí)，江蘇約克機(jī)組冷凍油廠家，從壓縮機(jī)高壓端的檢測(cè)接頭加入一定量的氮?dú)猓節(jié)櫥蛶杭铀倥懦?，停止噴射壓力，關(guān)閉放油閥。然后拆下壓縮機(jī)的濾油器，江蘇約克機(jī)組冷凍油廠家，放出油箱中的所有潤(rùn)滑油，然后清洗并緊固濾油器。根據(jù)壓縮機(jī)的標(biāo)準(zhǔn)量添加潤(rùn)滑油。同時(shí)，系統(tǒng)被抽空。建議選擇高(低)壓側(cè)角閥或其他相對(duì)高點(diǎn)作為真空泵的觸點(diǎn)，以防止泵送冷凍油損壞真空泵。當(dāng)進(jìn)行真空保壓或檢漏時(shí)，觀察壓力是否反彈。注入潤(rùn)滑油，用干凈的塑料管連接到放油閥上，塑料管的另一端放入油桶中(塑料管放在油桶的底部)。注油時(shí)，油桶應(yīng)關(guān)閉，以減少空氣對(duì)油的污染。定期檢查或更換冷凍機(jī)油：首先次調(diào)試1000小時(shí)后，檢查并更換冷凍機(jī)油，清洗濾油器，江蘇約克機(jī)組冷凍油廠家。如果系統(tǒng)干凈，每10000小時(shí)可以更換一次。需要及時(shí)更換，避免變質(zhì)的中央空調(diào)**冷凍油對(duì)壓縮機(jī)起不到保護(hù)作用。江蘇約克機(jī)組冷凍油廠家</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="江蘇約克機(jī)組冷凍油廠家,冷凍油" src="https://tyunfile.71360.com/UploadFile/bingpu/637401018654409562/6386110.png"></div><p style="text-indent:25px">冷凍油有合適的粘度，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。較低的傾點(diǎn)、絮凝點(diǎn)，由于制冷機(jī)的工作溫度變化范圍較大，如氨制冷劑在壓縮時(shí)可高至160℃，而膨脹又下降至-10℃。因此冷凍機(jī)油的傾點(diǎn)要低，一般約低于冷凍溫度10℃，而且油的粘溫特性要好。以保證冷凍機(jī)油在低溫下能從蒸發(fā)器返回壓縮機(jī)。絮凝點(diǎn)也是檢驗(yàn)冷凍機(jī)油與制冷劑混合液在一定溫度下析出石蠟可能沉淀出不溶性極性物質(zhì)的一種使用性能指標(biāo)，冷凍機(jī)油的絮凝點(diǎn)一定不能高于蒸發(fā)器的蒸發(fā)溫度。江蘇約克機(jī)組冷凍油廠家普遍采用的制冷壓縮機(jī)冷凍油有13號(hào)、18號(hào)和25號(hào)三種。</p><div

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。</p><p style="text-indent:25px">在更換螺桿壓縮機(jī)冷凍時(shí)，分為兩種情況。首先，更換冷凍油不做內(nèi)部清理。壓縮機(jī)做泵集動(dòng)作，將系統(tǒng)冷媒回收到冷凝器側(cè)(注意泵集動(dòng)作較低吸氣壓力不低于0.5Kg/cm2G)，將壓縮機(jī)內(nèi)冷媒排除，保留些許內(nèi)部壓力作為動(dòng)力源，將冷凍油從壓縮機(jī)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(dòng)作如前所述，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)油過濾器接頭和清結(jié)孔法蘭(或油位開關(guān)法蘭)后，將冷水機(jī)的壓縮機(jī)油槽內(nèi)的污染物去除干凈，并檢查機(jī)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(jī)油過濾器，注意換新時(shí)過濾器接口螺母要旋緊，做好密封，防止內(nèi)漏;機(jī)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。冷凍油可以潤(rùn)滑壓縮機(jī)運(yùn)動(dòng)零部件表面，減少阻力和摩擦，降低功耗，延長(zhǎng)使用壽命。</p><div

style="text-indent:25px">可以根據(jù)一下幾個(gè)方面選擇冷凍機(jī)油：1、根據(jù)壓縮類型選用潤(rùn)滑油，冷凍機(jī)的壓縮機(jī)有活塞式、螺桿式和離心式三種，前兩種的潤(rùn)滑油與被壓縮的制冷劑直接接觸，要考慮到潤(rùn)滑油和制冷劑之間的相互影響問題。離心式所用的潤(rùn)滑油只是用來潤(rùn)滑轉(zhuǎn)子軸承，也可根據(jù)負(fù)荷及轉(zhuǎn)速的大小選用。2、根據(jù)制冷劑的類型選用潤(rùn)滑油，與制冷劑直接接觸的潤(rùn)滑油，要考慮二者之間的相互影響。如氟里昂一類的制冷劑能溶于礦物油，因而選用的潤(rùn)滑油粘度等級(jí)，應(yīng)比使用不溶性制冷劑的高一個(gè)等級(jí)，以防止?jié)櫥捅幌♂尯蟛荒鼙ＷC潤(rùn)滑。另外，還應(yīng)注意混入制冷劑中的少量潤(rùn)滑油會(huì)不會(huì)影響制冷系統(tǒng)的工作。冷凍機(jī)油的絮凝點(diǎn)便是檢查混入制冷劑中的潤(rùn)滑油是否析出蠟結(jié)晶而使制冷系統(tǒng)堵塞的質(zhì)量指標(biāo)。如果冷凍油油溫一直不穩(wěn)定且緩慢上升，則說明有故障。江蘇約克機(jī)組冷凍油一般加多少</p><p
