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。FS070R哪家好冷凍油在實(shí)驗(yàn)條件下冷卻到停止流動(dòng)的溫度稱為凝固點(diǎn)。</p><div

style="text-indent:25px">冷凍油開始析出石蠟(油變混濁)時(shí)的溫度稱為濁點(diǎn)，當(dāng)有制冷劑存在時(shí)，冷凍機(jī)油的濁點(diǎn)會(huì)下降。此外，全封閉和半封閉制冷機(jī)對(duì)冷凍機(jī)油的電擊穿電壓有一定的要求，一般要求在25kV以上。冷凍機(jī)油混用，幾種不同牌號(hào)的冷凍機(jī)油混合使用時(shí)，會(huì)造成冷凍機(jī)油的粘度降低，甚至?xí)茐挠湍さ男纬?，使軸承受到損害；如果兩種冷凍機(jī)油中，含有不同性質(zhì)的抗氧化添加劑，混合在一起時(shí)，就有可能產(chǎn)生化學(xué)變化，形成沉淀物，使壓縮機(jī)的潤(rùn)滑受到影響，故使用時(shí)要注意。冷凍機(jī)油中有雜質(zhì)。</p><p

style="text-indent:25px">冷凍油凝點(diǎn)和濁點(diǎn)的選擇：考慮的因素是蒸發(fā)溫度和制冷劑的種類。蒸發(fā)溫度低，要用凝點(diǎn) 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。冷凍油能夠在螺桿與壓縮室以及陰陽(yáng)螺桿間形成動(dòng)態(tài)密封。FS100A費(fèi)用</p><p style="text-indent:25px">如果冷凍油油溫一直不穩(wěn)定且緩慢上升，則說明有故障。FS070R哪家好</p><p
