style="text-indent:25px">如今家用冰箱和空調(diào)器壓縮機都是容積式，其中又可分為往復式和旋轉(zhuǎn)式。往復式壓縮機使用的是活塞、曲柄、連桿機構(gòu)或活塞、曲柄，上海2EES-4(Y)維修、滑管機構(gòu)，旋轉(zhuǎn)式使用的多是滾動轉(zhuǎn)子壓縮機。在商用空調(diào)上，又多是離心式、渦旋式、螺桿式。按應用范圍又可分為低背壓式，上海2EES-4(Y)維修、中背壓式、高背壓式。低背壓式 ( 蒸發(fā)溫度 -35 ~ -15 ℃ ) ，一般用于家用電冰箱、食品冷凍箱等。中背壓式 ( 蒸發(fā)溫度 -20 ~ 0 ℃ ) ，上海2EES-4(Y)維修，一般用于冷飲柜、牛奶冷藏箱等。高背壓式 ( 蒸發(fā)溫度 -5 ~ 15 ℃ ) ，一般用于房間空氣調(diào)節(jié)器、除濕機、熱泵等。壓縮機從電氣強度、泄漏電流、堵轉(zhuǎn)，以及過載運行試驗等。上海2EES-4(Y)維修</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="上海2EES-4(Y)維修,壓縮機"

style="text-indent:25px">壓縮機造型原則：①、壓縮機容量應根據(jù)各蒸發(fā)溫度系統(tǒng)總機械負荷乘以運轉(zhuǎn)時間系數(shù)確定。除特殊要求外，一般不設備用機。②、選用活塞往復式氟利昂壓縮機時，當壓縮比大于10應采用雙級壓縮機;小于或等于10應采用單級壓縮。氟利昂雙級壓縮系統(tǒng)一般宜采用一級節(jié)流中間不完全冷卻方式。③、一般在冷庫中一些的冷卻器、油分離器、冷凝器、貯液器等設備均應與氟利昂制冷壓縮機的制冷能力相適應。④、選用氟利昂制冷壓縮機的工作條件，不得超過深圳冷庫企業(yè)規(guī)定的限定工作條件。⑤、氟利昂冷藏制冷系統(tǒng)中，一般應采用回熱循環(huán)。⑥、制冷壓縮機的運轉(zhuǎn)時數(shù)，對于5~100t的深圳冷庫，一般可采用每晝夜運轉(zhuǎn)12~16h。上海2EES-4(Y)維修在國內(nèi)壓縮機供應不足的情況下，中國每年還需適量進口。</p><div

style="text-indent:25px">壓縮機的主要故障和原因分析：1、堵轉(zhuǎn)（卡死）：壓縮機不動，且發(fā)出“嗡嗡”聲：異物入，曲軸、活塞、氣缸等運動部件卡死；高低壓側(cè)的壓力不平衡；電機燒損；電壓過低；壓縮機缺油或過負荷運行，機械部件嚴磨；油劣化，機械部件嚴磨；低溫制熱時，壓縮機溫度過低；壓縮機電容損壞或衰減；定轉(zhuǎn)子間隙不良。2、壓縮機可以動作，但排氣壓力低：壓縮機吸入液體；冷凝器故障；保護器動作；管道阻力大。3、壓縮機可以動作，但因電流逐漸增加而停機：保護器動作；吸氣壓力過高；壓縮機的機械部分受到損傷；</p><p style="text-indent:25px">取下和處理舊壓縮機：舊壓縮機必須在15分鐘內(nèi)將吸、排氣口封口；必須保證舊壓縮機編碼和機器條形碼清晰；清洗系統(tǒng)：清洗液要求高溶油、容易揮發(fā)，推薦使用R11；必須保證焊接處管口的清潔。換上新壓縮機：原則上要求使用原型號原品牌壓縮機，實在無法滿足則必須保證新壓縮機能力與舊壓縮機能力一致；渦旋壓縮機與轉(zhuǎn)子式壓縮機不能互換；單相壓縮機與三相壓縮機不能互換；拔壓縮機膠塞必須先排氣管后吸氣管；維修過程必須保證潤滑油不能接觸壓縮機膠腳，以免膠腳變質(zhì)。焊接新壓縮機：必須充氮焊接，且保證氮氣到達焊接位置；預熱至銅管變粉紅色為宜；必須由銅管的溫度來融化焊條，而不是由火焰直接熔?；钊麎嚎s機一般由殼體、電動機、缸體、活塞、控制設備 (啟動器和熱保護器) 及冷卻系統(tǒng)組成。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="上海2EES-4(Y)維修,壓縮機"

style="text-indent:25px">在正常情況下，過載保護器的觸點是閉合的。但如果過載保護器上的電阻絲損壞或雙金屬片觸點跳開后不能復位，使電路被切斷，壓縮機也就無法運轉(zhuǎn)。接著應檢查啟動繼電器。壓縮機啟動時要依賴于啟動繼電器。如果啟動繼電器失靈，也會使壓縮機無法啟動。上述檢查可用萬用表進行，如發(fā)現(xiàn)損壞應及時更換。否則就是壓縮機內(nèi)部的故障，或電機繞組出現(xiàn)短路、斷路和燒毀，或壓縮機本身被損壞，對此，需拆壓縮機進行修理。壓縮機工作一點時間后，用手觸摸壓縮機上的兩根銅管，其中一根燙手，另一根冰涼是正常的，若長時間運轉(zhuǎn)，兩根銅管溫差不大，則可能冷媒泄漏了。開機一段時間，兩根銅管溫差分明，但冰箱內(nèi)部不制冷，則可能是循環(huán)管道內(nèi)部結(jié)冰而堵塞。對于大型高壓壓縮機，在公稱壓力下的運轉(zhuǎn)時間不得少于24小時;上海ZB21KQ-TFD-558閥片</p><p

style="text-indent:25px">更換壓縮機的步驟和注意點：1、放冷媒：注意作業(yè)環(huán)境通風，放冷媒速度不能太快，以免人員被冷媒凍著；放冷媒速度不能太快，以免壓縮機內(nèi)的冷凍機油隨冷媒被放出，一旦壓縮機經(jīng)后續(xù)檢查為完好，缺少冷凍油將影響正常使用。留意噴出冷媒顏色，如噴出為白色或無色，則系統(tǒng)內(nèi)部清潔度較高。壓縮機可能沒有損壞。務必小心操作！2、拆除吸排氣管：充氮操作，避免系統(tǒng)內(nèi)部產(chǎn)生氧化皮，留意銅管內(nèi)壁是否有雜質(zhì)異物存在。3、空載運行：舊壓縮機拆除前，保證吸排氣管管口都敞開的狀態(tài)下，運行時間不超過5秒鐘,判斷壓縮機單體是否堵轉(zhuǎn)、有無吸排氣。測試壓縮機是否有吸排氣可用手指接近排氣口感受；絕緣耐壓不良、運行電流大的舊壓縮機可能漏電，不能以此種方法測試。上海2EES-4(Y)維修</p><p
