style="text-indent:25px">冷凍機長期運行會導致設備被水垢堵塞，將會使效率降低、能耗增加、壽命縮短。如果水垢不能被及時地清理，就會面臨設備維修、停機或者報廢更換的危險。長期以來傳統(tǒng)的清洗方式如機械方法（刮、刷）、高壓水、化學清洗(酸洗)等在對冷凍機清洗時出現很多問題：不能徹底清理水垢等沉積物，并對設備造成腐蝕，殘留的酸對材質產生二次腐蝕或垢下腐蝕，之后導致更換設備，此外，清洗廢液有毒，需要大量資金進行廢水處理。企業(yè)可采用高效環(huán)保清洗劑避免上述情況，其具有高效、環(huán)保、安全、無腐蝕特點，不但清洗效果良好而且對設備沒有腐蝕，能夠保證空壓機的長期使用。</p><p 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化的熱量一起傳遞給冷卻介質帶走。節(jié)流閥對制冷劑起節(jié)流降壓作用、同時控制和調節(jié)流入蒸發(fā)器中制冷劑液體的數量，并將系統(tǒng)分為高壓側和低壓側兩大部分。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濟性，可靠性和安全性而設置的。冷凍機系指壓縮制冷方式所采用的壓縮冷凍機機，按冷凍機結構和工作原理上的差別，它與空氣壓縮機類似。</p><div

style="text-indent:25px">冷凍機的特性：來自蒸發(fā)器的制冷劑蒸汽先進入低壓級汽缸壓縮到中間壓力，經過中間冷卻后再進入高壓級汽缸，壓縮到冷凝壓力進入冷凝器中。一般蒸發(fā)溫度在-25℃~-50℃時，應采用雙級壓縮機進行制冷。制冷系統(tǒng)由蒸發(fā)器、雙級壓縮機、油分離器、冷凝器、中間冷卻器、貯氨器、氨液分離器、節(jié)流閥及其它附屬設備等組成，相互間通過管子聯接成一個封閉系統(tǒng)。其中，中間冷卻器利用少量液態(tài)制冷工質在中間壓力下汽化吸熱，使低壓級排出的過熱蒸汽得到冷卻，降低高壓級的吸氣溫度，同時還使高壓液態(tài)制冷工質得到冷卻。對于冷凍機中的水冷設備，要經常查檢冷卻水的渾濁度。要經常對冷卻水進行必要更換。杭州專業(yè)冷凍機推薦廠家</p><p style="text-indent:25px">冷凍機主要由壓縮機、膨脹閥、蒸發(fā)器、冷凝器和附件、管路組成。安徽專業(yè)冷凍機廠家</p><p style="text-indent:25px">冷凍機機節(jié)能原則：提高蒸發(fā)溫度，降低冷凝溫度。在滿足設備安全和生產需求的前提下，盡量提高蒸發(fā)溫度和降低冷凝溫度。為此加大了冷卻塔的改造，以保證冷卻水效能。防止和減少管道結垢以提高冷凝器和蒸發(fā)器的換熱效率補充水如果水處理做的不好，碳酸氫鈣和碳酸氫鎂受熱產生的碳酸鈣和碳酸鎂會沉積在管道上。使導熱性能下降，影響冷凝器和蒸發(fā)器的換熱效率，并使設備運行電費大幅度上升。此時除了采用水處理技術外，還可以利用管道定期自動清洗設備進行管道清洗。安徽專業(yè)冷凍機廠家</p></p><br
