冷水機原理：冷水機，也叫做冷卻水循環機、工業冷水機或冷水機組。它被廣泛地應用在各個領域，最常見的領域有以下幾個類別：
1、研磨機行業。研磨機在運行時，三輥機在研磨過程產生會產生高溫。溫度過高影響機器的生產效率，原料的質量，甚至對會設備造成傷害。這時往往需要使用冷水機進行冷卻，降研磨機的高溫，保護機器。
2、食品、制藥行業。許多食品或藥品在生產中需要加溫，然后冷卻的過程中需要用到冷水機。還有給部分藥品機械部件進行降溫處理。
3、包(bao)裝(zhuang)行業。塑料包(bao)裝(zhuang)加溫(wen)后(hou)的(de)在生(sheng)產流(liu)水(shui)線上(shang)的(de)食品或藥品急需進行包(bao)裝(zhuang)作業，冷水(shui)機可(ke)在最快的(de)時間內把溫(wen)度(du)降到適合包(bao)裝(zhuang)的(de)溫(wen)度(du)，從而提高工(gong)作效率。

   工(gong)(gong)(gong)(gong)業(ye)(ye)(ye)油冷(leng)(leng)卻(que)器(qi)又稱工(gong)(gong)(gong)(gong)業(ye)(ye)(ye)水冷(leng)(leng)卻(que)器(qi)，是(shi)油冷(leng)(leng)卻(que)器(qi)的一種，廣泛應用于化工(gong)(gong)(gong)(gong)(科學)工(gong)(gong)(gong)(gong)業(ye)(ye)(ye)、塑(su)料制(zhi)品(pin)、塑(su)料容器(qi)、制(zhi)膜(mo)、塑(su)鋼型材、管道、電(dian)(dian)線、電(dian)(dian)纜護套、輪胎(tai)工(gong)(gong)(gong)(gong)業(ye)(ye)(ye)、電(dian)(dian)鍍(du)和機床切削液(ye)冷(leng)(leng)卻(que)工(gong)(gong)(gong)(gong)業(ye)(ye)(ye)、制(zhi)藥工(gong)(gong)(gong)(gong)業(ye)(ye)(ye)、電(dian)(dian)子工(gong)(gong)(gong)(gong)業(ye)(ye)(ye)、五金工(gong)(gong)(gong)(gong)業(ye)(ye)(ye)、食(shi)品(pin)飲料工(gong)(gong)(gong)(gong)業(ye)(ye)(ye)、制(zhi)鞋工(gong)(gong)(gong)(gong)業(ye)(ye)(ye)、實驗(yan)室等主要行業(ye)(ye)(ye)。

   在各種(zhong)工(gong)(gong)業(ye)生產(chan)(chan)(chan)過(guo)程中，由于機械、模(mo)具和化學反(fan)應，工(gong)(gong)作過(guo)程中會產(chan)(chan)(chan)生熱量。當溫度(du)超過(guo)材料(liao)的(de)接受(shou)度(du)時，產(chan)(chan)(chan)品(pin)(pin)質量不(bu)穩定。以(yi)(yi)(yi)塑(su)料(liao)制品(pin)(pin)和電鍍(du)(du)(du)制品(pin)(pin)為例，塑(su)料(liao)制品(pin)(pin)在生產(chan)(chan)(chan)中冷卻(que)時間占整(zheng)個(ge)周(zhou)期的(de)80%以(yi)(yi)(yi)上。由此(ci)可見減少冷卻(que)時間的(de)重要性。工(gong)(gong)業(ye)油冷卻(que)器(qi)能(neng)及(ji)時吸收熱量，使模(mo)腔溫度(du)迅(xun)(xun)速(su)下降，加快產(chan)(chan)(chan)品(pin)(pin)定型，縮(suo)短(duan)開模(mo)時間，提高生產(chan)(chan)(chan)能(neng)力(li)。在電鍍(du)(du)(du)生產(chan)(chan)(chan)中，工(gong)(gong)業(ye)冷油可以(yi)(yi)(yi)降低電鍍(du)(du)(du)溶液(ye)的(de)溫度(du)，使溫度(du)在一定范圍內保持恒(heng)定，使金(jin)屬分子以(yi)(yi)(yi)穩定的(de)電流迅(xun)(xun)速(su)附(fu)著在電鍍(du)(du)(du)件表面，從而增加產(chan)(chan)(chan)品(pin)(pin)的(de)光滑度(du)和密度(du)。
