style="text-indent:25px">冷凍壓縮機排氣溫度過高的原因有：⑴壓縮機汽缸中余隙過大。⑵壓縮機中吸、排氣閥門、活塞環(huán)損壞。⑶壓縮機安全旁通閥泄漏。⑷壓縮機吸氣溫度過高。⑸壓縮機汽缸中潤滑油中斷。⑹壓縮機吸氣壓力過低或吸氣閥開的過小。⑺壓縮機吸氣管道或過濾器有堵塞現(xiàn)象，隔熱層保溫層損壞。⑻壓縮機回氣管道中阻力過大，氣體流動速度慢易產(chǎn)生過熱現(xiàn)象，致使排氣溫度升高。⑼冷凍壓縮機冷凝壓力過高；冷凝器中有油垢或水垢等。⑽壓縮機缸蓋冷卻水套水量不足；或冷卻水溫度過高。⑾壓縮機的制冷能力小于庫房設備能力，如蒸發(fā)面積過大。⑿壓縮機排氣管道中阻力過大。⒀冷凍壓縮機節(jié)流閥開啟度過大或堵塞。⒁壓縮機自身效率差。⒂氨液分離器安裝高度過低。</p><p style="text-indent:25px">冷凍壓縮機是作為制冷機中一重要組成部分而與系統(tǒng)中其它部件，如熱交換器，節(jié)流裝置等配合工作而獲得制冷的效果。因此，它的工作能力有必要直觀地用單位時間內(nèi)所產(chǎn)生的冷量——制冷量來表示，單位為匹它是冷凍壓縮機的重要性能指標之一。為了便于比較和選用，有必要根據(jù)其不用的使用條件規(guī)定統(tǒng)一的工況來表示壓縮機的制冷量，根據(jù)標準規(guī)定，吸氣工質(zhì)過熱所吸收的熱量也應包括在壓縮機的制冷量內(nèi)。排熱量是壓縮機的制冷量和部分壓縮機輸入功率的當量熱量之和，它是通過系統(tǒng)中的冷凝器排出的。這個參數(shù)對于熱泵系統(tǒng)中的壓縮機來講是一個十分重要的性能指標；在設計制冷系統(tǒng)的冷凝器時也是必須知道的。蒸汽噴射式冷凍機依靠蒸汽噴射器（噴射式壓縮器）的作用完成制冷循環(huán)。</p><div

style="text-indent:25px">在冷凍機中，蒸發(fā)器、冷凝器、壓縮機和節(jié)流閥是制冷系統(tǒng)中必不可少的四大件，這當中蒸發(fā)器是輸送冷量的設備。制冷劑在其中吸收被冷卻物體的熱量實現(xiàn)制冷。壓縮機是心臟，起著吸入、壓縮、輸送制冷劑蒸汽的作用。冷凝器是放出熱量的設備，將蒸發(fā)器中吸收的熱量連同壓縮機做功所轉(zhuǎn)化的熱量一起傳遞給冷卻介質(zhì)帶走。節(jié)流閥對制冷劑起節(jié)流降壓作用、同時控制和調(diào)節(jié)流入蒸發(fā)器中制冷劑液體的數(shù)量，并將系統(tǒng)分為高壓側(cè)和低壓側(cè)兩大部分。實際制冷系統(tǒng)中，除上述四大件之外，常常有一些輔助設備，如電磁閥、分配器、干燥器、集熱器、易熔塞、壓力控制器等部件組成，它們是為了提高運行的經(jīng)濟性，可靠性和安全性而設置的。冷凍機企業(yè)想要抓住這個機遇實現(xiàn)大發(fā)展的話，必須在科技研發(fā)上面下功夫。江西鋁氧化**冷凍機商家</p><p style="text-indent:25px">冷凍機廣泛應用于工農(nóng)業(yè)生產(chǎn)和日常生活中。江西鋁氧化**冷凍機商家</p><p style="text-indent:25px">冷凍機的保養(yǎng)與維護： 1、運轉(zhuǎn)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(jié)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(diào)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(zhuǎn)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(nèi)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。江西鋁氧化**冷凍機商家</p></p><br /><p>文章來源地址:
