style="text-indent:25px">選擇冷凍油應(yīng)考慮的因素：1、粘度，壓縮機(jī)的轉(zhuǎn)速越高，使用冷凍機(jī)油的粘度應(yīng)越大，實(shí)際使用中一般低速立式雙缸壓縮機(jī)可使用L-DRAl5號(hào)冷凍油，中速和高速多缸壓縮機(jī)應(yīng)使用L-DRA22號(hào)或L-DRA32號(hào)冷凍油，某些高速重載壓縮機(jī)的發(fā)熱量大，油溫高，氣溫也高，較好使用L-DRA46號(hào)或L-DJRA68號(hào)冷凍油。2、熱穩(wěn)定性，熱穩(wěn)定性一般用冷凍機(jī)油的閃點(diǎn)來(lái)衡量。閃點(diǎn)是指冷凍機(jī)油的蒸汽遇火后發(fā)生閃火的溫度。冷凍機(jī)油的閃點(diǎn)必須高于壓縮機(jī)的排氣溫度，如R717，R12，R22壓縮機(jī)使用的冷凍機(jī)油閃點(diǎn)應(yīng)在160℃以上。</p><p

(或3個(gè)月) 應(yīng)更換一次潤(rùn)滑油，若沒(méi)有條件的至少要更換一次油過(guò)濾器芯。冷水機(jī)的壓縮機(jī)就象汽車的發(fā)動(dòng)機(jī)一樣，家里的汽車多長(zhǎng)時(shí)間檢查一次，單位的制冷系統(tǒng)的油過(guò)濾器芯也應(yīng)該更換一次。但國(guó)內(nèi)的習(xí)慣是每次開機(jī)，只要電路不壞，就一直讓風(fēng)冷螺桿式冷水機(jī)壓縮機(jī)運(yùn)行，等壓縮機(jī)壞了再去維修，但殊不知更換一個(gè)小小的濾芯，能夠較大提高壓縮機(jī)的減少磨損，保持能效，提高壽命。若冷凍油黏度過(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。上海B08多少錢</p><p

style="text-indent:25px">冷凍油的作用：1）在螺桿與壓縮室以及陰陽(yáng)螺桿之間形成動(dòng)態(tài)密封，減少制冷劑在壓縮過(guò)程中由高壓側(cè)向低壓側(cè)的泄漏。2）冷卻被壓縮的制冷劑，油被噴入壓縮機(jī)內(nèi)，吸收制冷劑氣體在壓縮過(guò)程中產(chǎn)生的熱量，降低排氣溫度。3）在軸承以及螺桿之間形成油膜支撐轉(zhuǎn)子，并開始潤(rùn)滑作用。4）傳遞壓差力，驅(qū)動(dòng)容量調(diào)節(jié)系統(tǒng)，通過(guò)壓縮機(jī)的加卸載電磁閥的動(dòng)作，調(diào)節(jié)容調(diào)滑塊的位置，實(shí)現(xiàn)壓縮機(jī)容量調(diào)節(jié)控制。5）降低運(yùn)轉(zhuǎn)噪音。冷凍油主要監(jiān)測(cè)指標(biāo)：1）PH值指標(biāo)：潤(rùn)滑油的酸化，會(huì)直接影響壓縮機(jī)的電機(jī)壽命，故應(yīng)定期檢查潤(rùn)滑油之酸度是否合格。一般潤(rùn)滑油酸度低于PH6以下即須更換。若無(wú)法檢查酸度則應(yīng)定期更換系統(tǒng)之干燥過(guò)濾器，使系統(tǒng)干燥度保持在正常狀態(tài)下。2）污染度指標(biāo)：如果100ml的冷凍油中分子量超過(guò)5mg，建議更換冷凍油。3）含水量：超過(guò)100ppm，需要更換冷凍油。上海B08多少錢</p><p
