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(kāi)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。</p><p

Oil)用于制冷壓縮機(jī)內(nèi)各運(yùn)動(dòng)部件潤(rùn)滑的油稱(chēng)為冷凍油。在壓縮機(jī)中，冷凍油主要起潤(rùn)滑、密封、降溫及能量調(diào)節(jié)等功能。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。冷凍油不斷沖洗摩擦表面，帶走磨屑，可減少摩擦件的磨損。蘇州冷凍油企業(yè)</p><p

style="text-indent:25px">不同牌號(hào)的冷凍油切不可混用，尤其是礦物油和合成酯類(lèi)油切不可混用。如果更換不同牌號(hào)的冷凍油，注意要將系統(tǒng)內(nèi)殘存的原冷凍油排除掉。有些油品因有吸濕的特性，所以不要將冷凍油長(zhǎng)期暴露在空氣中。安裝時(shí)盡可能縮短暴露的時(shí)間，并做好抽真空操作。如果系統(tǒng)發(fā)生過(guò)壓縮機(jī)電機(jī)燒毀故障，更換新機(jī)時(shí)要特別注意將系統(tǒng)殘存的酸性物質(zhì)去除，并在調(diào)試運(yùn)轉(zhuǎn)七十二小時(shí)后檢查冷凍油的酸度，建議更換冷凍油和干燥過(guò)濾器，降低酸蝕的可能。此后運(yùn)轉(zhuǎn)一個(gè)月左右再次檢測(cè)或更換一次冷凍油。如果系統(tǒng)曾發(fā)生過(guò)進(jìn)水的事故，要特別注意將水分去除干凈，除更換冷凍油外，要特別注意檢測(cè)油品的酸度，并及時(shí)更換新油和干燥過(guò)濾器。蘇州冷凍油企業(yè)</p><p
