style="font-size:14px;">在冷庫安裝投入運行使用后，冷庫設備的日常保養(yǎng)也是至關重要的。從廣面來看，制冷設備的使用壽命及冷庫的運行性能，很大程度上取決于它的日常維護保養(yǎng)。特別是大型的冷庫設備，由于投入資本龐大，且控制著整個企業(yè)的正常運營，為防止機器因疏于保養(yǎng)而引起故障造成具大的損失，故在日常工作中進行一些保養(yǎng)工作是不容輕視的。冷庫設備需要日常保養(yǎng)，特別是長期停用后再次使用，降溫的速度要適當合理，比較好的溫度是每天控制在8-10度，在0度時應保持一點時間，不可隨意亂調(diào)。</span></p><p> <strong><span style="font-size:14px;">制冷設備中氣密性的測試：</span></strong> </p> <p> <span style="font-size:14px;">充氮焊接完成之后并不能**焊接好了，如果焊接有沙眼氣泡等，需要重新焊接。因為需要氣密性測試。即焊接完成后必須對銅管進行的壓力測試，往銅管內(nèi)充入一定壓力的氮氣進行保壓，用氮氣從低壓工藝口慢慢打入，如果系統(tǒng)有液路電磁閥先將電磁閥通電打開，在高壓工藝口掛正壓表檢測壓力。</span> </p> <p> <span style="font-size:14px;">R410A冷媒需保持管壓力為40公斤，R22制冷劑則需要保持管內(nèi)壓力為20公斤。保壓時長24小時。環(huán)境溫度的變化能引起的氮氣壓力變化，環(huán)境溫度每有±1℃溫差，便會有±0.1 kgf/cm2的壓力差。</span> </p> <p> <strong><span style="font-size:14px;">需要注意：</span></strong><span style="font-size:14px;">依然嚴禁用氧氣進行保壓，氧氣與制冷系統(tǒng)里面的冷凍油接觸，容易發(fā)生！</span> 以“科學管理、技術指導、完美服務”為宗旨。</p><div style="width:100%;text-align: center;"><img

style="text-indent:25px"><span style="font-size:14px;">制冷設備由制冷系統(tǒng)和電氣系統(tǒng)組成，它的運行狀態(tài)又與工作環(huán)境和條件有密切的關系，所以對制冷設備的故障分析需要綜合考慮。故障原因可分為兩類：一類為機外原因或人為故障（特別是電源是否正常），另一類則為機內(nèi)故障。在分析處理故障時，首先應排除機外原因。排除機外因素后，又可將機內(nèi)故障分為制冷系統(tǒng)故障和電氣系統(tǒng)故障兩類，一般應先排除電氣系統(tǒng)故障。至于電氣系統(tǒng)故障，又可從以下兩方面來查找：開關電源是否送電；電動機繞組是否正常。按照上述總的分析思路，便可逐步縮小故障范圍，故障原因也就自然水落石出了。</span>銷售是服務的開始，專業(yè)的技術人員在線服務。昆明冷庫制冷設備批發(fā)公司</p><p

style="font-size:14px;">1、搖表搖，500V的搖表即可，搖三個接線柱上的線對電機外殼的絕緣阻值，應該在0.5M歐以上就說明沒有對地短路。</span> </p> <p> <span style="font-size:14px;">2、萬用表測：測U、V、W三相間的阻值，是否相等，應該是差不多，差的太多也能轉(zhuǎn)，但是用不長了，記住電機越大，阻值越小！但是不能三相都為0歐，除非你是特別大，如50KW以上的電機!記住如果是調(diào)速電機的6個端子阻值可不一樣。</span> </p> <p> <span style="font-size:14px;">3、檢查軸承、風扇，一般纏電機就讓全換了!因為有時候軸承抱死也會燒電機的。</span> </p> <p> <span style="font-size:14px;">4、電機的空載電流一般為額定電流的10％～50％。</span> </p> <p> <span style="font-size:14px;">5、電機額定電流運行時，是滿負荷運行，輸出功率基本為100％。運行電流小，說明電機輸出功率變小，是輕負載運行。</span> </p> <p> <br /> </p> <p> <br /> 昆明冷庫制冷設備批發(fā)公司</p></p><br /><p>文章來源地址:
