style="text-indent:25px">冷凍機常見的故障問題解析：吸氣溫度過低。主要是蒸發(fā)器供液量偏大導致吸氣過熱度低造成的。(1)制冷劑充注量太多：占據(jù)了冷凝器內部分容積而使冷凝壓力增高，進入蒸發(fā)器的液體隨之增多。蒸發(fā)器中液體不能完全氣化，使壓縮機吸人的氣體中帶有液體微滴。這樣，回氣管道的溫度下降，但蒸發(fā)溫度因壓力未下降而未變化，過熱度減小。即使關小膨脹閥也無明顯改善。(2)膨脹閥開啟度過大：由于感溫元件綁扎過松、與回氣管接觸面積小，或者感溫元件未用絕熱材料包扎及其包扎位置錯誤等，致使感溫元件所測溫度不準確，接近環(huán)境溫度，使膨脹閥動作的開啟度增大，導致供液量過多。上海專業(yè)鋁氧化**冷凍機廠家價格由于壓縮機運轉工況改變，操作管理不同，冷凍機產冷量和耗能也隨著變化。</p><div

style="text-indent:25px">螺桿冷凍壓縮機蒸發(fā)器效率低或高：蒸發(fā)器效率低主要影響的是被冷卻物的降溫，而影響壓縮機的是濕沖程。而效率高呢，又會造成吸氣過熱度偏大，進而影響壓縮機排氣溫度。油路問題：主要體現(xiàn)在油的質量，潔凈度，回油溫度等潤滑油在螺桿壓縮機制冷系統(tǒng)中的主要作用是潤滑，降溫，密封。回油的溫度在很大程度上影響了螺桿壓縮機的使用壽命，一般推薦工作溫度為40~60℃之間，有部分廠家也有標注70℃或80℃的。過高的油溫會造成油的焦化，破壞油膜的形成，油溫還影響排氣溫度高低，進而影響壓縮比，所以，請在選擇油溫時注意調整。</p><p style="text-indent:25px">冷凍壓縮機是制冷循環(huán)的動力，它由電動機拖動而不停地旋轉，它除了及時抽出蒸發(fā)器內蒸氣，維持低溫低壓外，還通過壓縮作用提高制冷劑蒸氣的壓力和溫度，創(chuàng)造將制冷劑蒸氣的熱量向外界環(huán)境介質轉移的條件。即將低溫低壓制冷劑蒸氣壓縮至高溫高壓狀態(tài)，以便能用常溫的空氣或水作冷卻介質來冷凝制冷劑蒸氣。制冷冷凝器是一個熱交換設備，作用是利用環(huán)境冷卻介質(空氣或水)，將來自壓縮機的高溫高壓制冷蒸氣的熱量帶走，使高溫高壓制冷劑蒸氣冷卻、冷凝成高壓常溫的制冷劑液體。值得一提的是，冷凝器在把制冷劑蒸氣變?yōu)橹评鋭┮后w的過程中，壓力是不變的，仍為高壓。間接冷卻是靠冷凍機蒸發(fā)器中制冷劑的蒸發(fā)，冷卻速度慢，總傳熱溫差大，系統(tǒng)也較復雜，故只用于較少場合。</p><div

2、合理選擇壓縮機運轉臺數(shù)，使其制冷能力與系統(tǒng)的熱負荷相匹配。??? 3、根據(jù)工藝要求和外界氣溫變化，適當調節(jié)風機和水泵的運轉臺數(shù)。??? 4、定期放油，放空氣，除霜和除去水垢，保持設備良好的傳熱效果，避免冷凝壓力過高和蒸發(fā)壓力過低。變排量冷凍機壓縮機可以根據(jù)設定的溫度自動調節(jié)功率輸出。上海專業(yè)鋁氧化**冷凍機廠家價格</p><p

1、運轉機組：要經(jīng)常觀察壓縮機的油面及回油情況及油的清潔度，發(fā)現(xiàn)油臟或油面下降要及時解決，以免造成潤滑不良。 2、對于風冷機組：要經(jīng)常清掃風冷器使其保持良好的換熱狀態(tài)。對于水冷機組：要經(jīng)常檢查冷卻水的混濁程度，如冷卻水太臟，要進行更換。檢查供水系統(tǒng)有無泡、冒、滴、漏問題。水泵工作是否正常，閥門開關是否有效，冷卻塔.風機是否正常。對于冷風機組：經(jīng)常檢查冷凝器出現(xiàn)結垢問題，要及時除去水垢。 3、對于風冷機的蒸發(fā)器：要經(jīng)常檢查除霜情況，除霜是否及時有效，會影響制冷效果，導致制冷系統(tǒng)的回液。 4、經(jīng)常觀察壓縮機運行狀態(tài)，檢查其排氣溫度，在換季運行時，要特別注意系統(tǒng)的運行狀態(tài)，及時調整系統(tǒng)供液量和冷凝溫。 5、仔細傾聽壓縮機，冷卻塔、水泵或冷凝器風機運轉聲音：發(fā)現(xiàn)異常及時處理，同時檢查壓縮機、排氣管及地腳的振動情況。 6、對壓縮機的維護：初期系統(tǒng)內部清潔度較差，在運行30天后要更換一次冷凍油和干燥過濾器，在運行半年之后再更換一次（要根據(jù)實際情況而定）。對于清潔度較高的系統(tǒng)，運行半年以后也要更換一次冷凍油和干燥過濾器，以后視情況而定。上海專業(yè)鋁氧化**冷凍機廠家價格</p></p><br /><p>文章來源地址:
