style="text-indent:25px">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，冷凍油能夠在螺桿與壓縮室以及陰陽螺桿間形成動(dòng)態(tài)密封，減少制冷劑在壓縮過程中由高壓側(cè)向低壓側(cè)的泄漏及減少相互間的機(jī)械摩損，冷凍油可以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程中產(chǎn)生的熱量，降低排氣溫度；冷凍油可以對(duì)冷水機(jī)軸承起潤(rùn)滑作用；冷凍油能夠傳遞壓差力量，驅(qū)動(dòng)容量調(diào)節(jié)系統(tǒng)，經(jīng)由壓縮機(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)冷水機(jī)壓縮機(jī)容量調(diào)節(jié)控制；冷凍油還可以降低水冷螺桿式冷水機(jī)運(yùn)轉(zhuǎn)噪音。因此，可以說冷水機(jī)的使用好壞，都主要集中在油的選擇及使用上及系統(tǒng)回油，冷卻的設(shè)計(jì)上。大的類型選定后，還要根據(jù)不同的工況選擇不同牌號(hào)的油。上海約克K油管道</p><p

和濁點(diǎn)低的潤(rùn)滑油。采用氟利昂制冷劑時(shí)，潤(rùn)滑油的凝點(diǎn)和濁點(diǎn)要稍高于蒸發(fā)溫度；采用氨制冷劑時(shí)，潤(rùn)滑油的凝點(diǎn)和濁點(diǎn)要低于蒸發(fā)溫度。目前國(guó)產(chǎn)的潤(rùn)滑油凝點(diǎn)*有二種規(guī)格，即 -40℃ 和 -25℃。-25℃潤(rùn)滑油可用于蒸發(fā)溫度高于 -20℃的氨制冷壓縮機(jī)和蒸發(fā)溫度低于 -20℃的氟利昂制冷壓縮機(jī)。當(dāng)氨制冷壓縮機(jī)的蒸發(fā)溫度低于 -20℃時(shí)，就應(yīng)選用 -40℃的潤(rùn)滑油。主要因素是排氣溫度。排氣溫度的高低，和制冷壓縮機(jī)的型式有關(guān)，并和選擇的潤(rùn)滑油是否合適有關(guān)。排氣溫度高，要求潤(rùn)滑油閃點(diǎn)也高。一般都要求排氣溫度比潤(rùn)滑油的閃點(diǎn)低15 ～ 30℃左右。開利PP47-33報(bào)價(jià)</p><p
