制冷機組

吸收式剛察(cha)縣工業冷熱一體冷水機的(de)自(zi)動(dong)運行，需要將與(yu)機組正常運行有關的(de)泵、風機等設(she)備(bei)與(yu)控制儀表聯動(dong)，并(bing)根據機組特點制定啟動(dong)、停止(zhi)、抽真空、自(zi)動(dong)溶晶(jing)等程序。

冷(leng)卻機(ji)(ji)工作原理(li)：干燥的(de)(de)濕(shi)(shi)物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)由皮(pi)帶輸(shu)送(song)(song)機(ji)(ji)或(huo)(huo)斗式(shi)提(ti)升(sheng)機(ji)(ji)送(song)(song)到料(liao)(liao)(liao)斗，然(ran)后(hou)經(jing)(jing)料(liao)(liao)(liao)斗的(de)(de)加料(liao)(liao)(liao)機(ji)(ji)通過加料(liao)(liao)(liao)管(guan)道進(jin)入(ru)(ru)加料(liao)(liao)(liao)端(duan)。加料(liao)(liao)(liao)管(guan)道的(de)(de)斜度要大于(yu)物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)的(de)(de)自然(ran)傾角，以便物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)順利(li)流(liu)入(ru)(ru)冷(leng)卻器(qi)內(nei)。冷(leng)卻器(qi)圓筒是(shi)一(yi)個與水平線略成(cheng)傾斜的(de)(de)旋轉圓筒。物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)從較高(gao)一(yi)端(duan)加入(ru)(ru)，載(zai)(zai)(zai)熱體(ti)由低端(duan)流(liu)出，與物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)成(cheng)逆流(liu)接(jie)(jie)觸，也有載(zai)(zai)(zai)熱體(ti)和物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)一(yi)起(qi)并(bing)(bing)流(liu)進(jin)入(ru)(ru)筒體(ti)的(de)(de)。隨著圓筒的(de)(de)轉動物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)受重力作用運行到較底(di)的(de)(de)一(yi)端(duan)。濕(shi)(shi)物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)在筒體(ti)內(nei)向前(qian)移動過程中(zhong)，直接(jie)(jie)或(huo)(huo)間(jian)接(jie)(jie)得(de)到了(le)載(zai)(zai)(zai)熱體(ti)的(de)(de)給熱，使(shi)熱物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)得(de)以冷(leng)卻，然(ran)后(hou)在出料(liao)(liao)(liao)端(duan)經(jing)(jing)皮(pi)帶機(ji)(ji)或(huo)(huo)螺旋輸(shu)送(song)(song)機(ji)(ji)送(song)(song)出。在筒體(ti)內(nei)壁上裝有抄板，它的(de)(de)作用是(shi)把物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)抄起(qi)來(lai)又撒(sa)下，使(shi)物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)與氣流(liu)的(de)(de)接(jie)(jie)觸表面(mian)增(zeng)大，以提(ti)高(gao)冷(leng)卻速(su)率并(bing)(bing)促(cu)進(jin)物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)前(qian)進(jin)。冷(leng)卻體(ti)一(yi)般分為冷(leng)空(kong)氣等(deng)。載(zai)(zai)(zai)熱體(ti)經(jing)(jing)冷(leng)卻器(qi)以后(hou)，一(yi)般需(xu)(xu)要旋風除(chu)塵(chen)(chen)器(qi)將氣體(ti)內(nei)所帶物(wu)(wu)(wu)(wu)料(liao)(liao)(liao)捕集(ji)下來(lai)。如需(xu)(xu)進(jin)一(yi)步減少尾氣含塵(chen)(chen)量，還(huan)應經(jing)(jing)過袋式(shi)除(chu)塵(chen)(chen)器(qi)或(huo)(huo)濕(shi)(shi)法除(chu)塵(chen)(chen)器(qi)后(hou)再(zai)放排放。

離心式冷凍(dong)機的主(zhu)要(yao)潤(run)滑部位(wei)是增速齒(chi)輪(lun)、主(zhu)軸承及軸端的機械密封。通常齒(chi)輪(lun)箱(xiang)可兼做(zuo)潤(run)滑油(you)(you)箱(xiang)，其中裝有電加(jia)熱(re)器(qi)可對潤(run)滑油(you)(you)進行預熱(re)，油(you)(you)泵用于將(jiang)油(you)(you)抽(chou)送到(dao)專設的高位(wei)油(you)(you)箱(xiang)，再由高位(wei)油(you)(you)箱(xiang)把油(you)(you)引到(dao)所需的潤(run)滑部位(wei)，該(gai)種方式可防止(zhi)油(you)(you)泵供油(you)(you)系(xi)統突(tu)然故障或(huo)冷凍(dong)機突(tu)然斷電停(ting)機時，油(you)(you)泵無油(you)(you)供給(gei)而冷凍(dong)機仍(reng)保持運轉(zhuan)或(huo)借慣性繼續高速回轉(zhuan)，因無潤(run)滑而造成(cheng)設備摩擦部位(wei)的“燒傷(shang)”或(huo)“咬合(he)”事故。

1. 開始

超低溫冷水機

先啟(qi)動(dong)冷卻水(shui)(shui)泵、冷媒水(shui)(shui)泵和冷卻塔風機(ji)，然后打開蒸(zheng)(zheng)汽源止(zhi)汽閥。待制冷劑水(shui)(shui)流(liu)量、熏蒸(zheng)(zheng)盆(pen)度、溶解溫度、彈簧(huang)熱(re)繼電器正常后，按(an)啟(qi)動(dong)按(an)鈕，溶液泵工(gong)(gong)作，吸收泵工(gong)(gong)作。可自(zi)動(dong)調節(jie)的蒸(zheng)(zheng)汽(或冷凝(ning)液)調節(jie)閥工(gong)(gong)作，供蒸(zheng)(zheng)汽。冷卻液水(shui)(shui)位到達后，冷卻液水(shui)(shui)泵工(gong)(gong)作。

2. 停車:

①停(ting)止令發出后，會停(ting)止一些正常的安全設備(bei)。關閉蒸(zheng)汽(或冷凝)調節閥(fa)。進(jin)入(ru)自(zi)動(dong)稀釋操作，直到濃縮溶液進(jin)入(ru)發生器和(he)吸收器。

冷(leng)(leng)水(shui)(shui)(shui)機(ji)俗稱冷(leng)(leng)凍機(ji)、制冷(leng)(leng)機(ji)、冰水(shui)(shui)(shui)機(ji)、凍水(shui)(shui)(shui)機(ji)、冷(leng)(leng)卻機(ji)等(deng)。因各行各業的(de)使(shi)用比較(jiao)廣泛，所以(yi)名(ming)字也就多得不計其(qi)數。隨著冷(leng)(leng)水(shui)(shui)(shui)機(ji)組行業的(de)不斷發(fa)展越來越多的(de)人(ren)類開始關注冷(leng)(leng)水(shui)(shui)(shui)機(ji)組行業任何選擇對人(ren)類來說(shuo)越來越重要(yao)，在產品結構上(shang)“高能效比水(shui)(shui)(shui)冷(leng)(leng)螺桿機(ji)組”、“水(shui)(shui)(shui)源熱(re)(re)泵機(ji)組”、“螺桿式(shi)熱(re)(re)回(hui)收機(ji)組”、“**熱(re)(re)泵機(ji)組”、“螺桿式(shi)低溫(wen)冷(leng)(leng)凍機(ji)組”等(deng)為主的(de)*具(ju)競(jing)爭力，其(qi)性質原理(li)是(shi)一個多功(gong)能的(de)機(ji)器，除去了液(ye)體蒸(zheng)氣通過(guo)壓縮或熱(re)(re)吸收式(shi)制冷(leng)(leng)循(xun)環。

②將介質(zhi)稀溶(rong)液(ye)(ye)充(chong)分(fen)混合，充(chong)分(fen)吸(xi)收蒸發器制(zhi)冷劑蒸汽。當溶(rong)液(ye)(ye)溫度降(jiang)至45℃以下時，溫控器起作用(yong)，溶(rong)液(ye)(ye)泵(beng)和(he)制(zhi)冷劑泵(beng)停止(zhi)運行。一般情況下，自動稀釋時間為15分(fen)鐘左右，因此也采(cai)用(yong)時間繼電(dian)器作為自動稀釋過程結束的信號。

最后停止剛察縣工業冷(leng)熱(re)一(yi)體冷(leng)水機制冷(leng)劑水泵、冷(leng)卻水泵和冷(leng)卻塔風(feng)機，關閉(bi)主蒸汽截止閥。

3.抽真空

真(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)工作(zuo)時，與真(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)系統(tong)連接的(de)真(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)電磁閥打開并(bing)開始(shi)抽真(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)。當真(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)度達到設計值時，真(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)停(ting)止(zhi)(zhi)運行，真(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)電磁閥關閉(bi)，切斷真(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)系統(tong)與真(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)之(zhi)間的(de)路(lu)徑。由于電磁閥呈三通(tong)懸掛，使泵(beng)(beng)(beng)與大氣相連，從而防止(zhi)(zhi)泵(beng)(beng)(beng)內潤滑油(you)回流到真(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)系統(tong)。在這里，真(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)的(de)啟動(dong)(dong)和停(ting)止(zhi)(zhi)是手動(dong)(dong)控制(zhi)的(de)。如果只在泵(beng)(beng)(beng)的(de)吸入端安裝一個**壓力變送器(qi)，就可以完全自動(dong)(dong)控制(zhi)真(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)的(de)啟動(dong)(dong)和停(ting)止(zhi)(zhi)。

4. 自動晶體融化

①管(guan)狀熔(rong)融(rong)晶體(ti)。在奧花坑(keng)機(ji)(ji)組(zu)的結(jie)構設計中，熔(rong)煉裝置(zhi)一(yi)般采用異形管(guan)。當(dang)濃溶液(ye)在換熱器(qi)內結(jie)晶時，濃溶液(ye)不能流入吸(xi)收(shou)器(qi)，發電(dian)機(ji)(ji)內液(ye)位(wei)(wei)上(shang)升。當(dang)液(ye)位(wei)(wei)上(shang)升到j型管(guan)出口時，高溫(wen)濃縮溶液(ye)將通(tong)過(guo)型管(guan)直接進入吸(xi)收(shou)塔，然后溶液(ye)泵將相對高溫(wen)的溶液(ye)通(tong)過(guo)換熱器(qi)送到發電(dian)機(ji)(ji)。一(yi)般結(jie)晶不嚴重時，可采用j管(guan)溢(yi)流熔(rong)煉法自動恢復機(ji)(ji)組(zu)正常運行(xing)。
