工(gong)(gong)業(ye)(ye)冷(leng)(leng)(leng)水(shui)機(ji)(ji)(ji)機(ji)(ji)(ji)組應用(yong)廣泛，在有(you)工(gong)(gong)業(ye)(ye)的(de)地方就(jiu)要(yao)用(yong)到冷(leng)(leng)(leng)水(shui)機(ji)(ji)(ji)設備，如(ru)：化(hua)工(gong)(gong)冷(leng)(leng)(leng)水(shui)機(ji)(ji)(ji)、電(dian)(dian)(dian)鍍冷(leng)(leng)(leng)水(shui)機(ji)(ji)(ji)、食品冷(leng)(leng)(leng)水(shui)機(ji)(ji)(ji)、電(dian)(dian)(dian)子加工(gong)(gong)冷(leng)(leng)(leng)水(shui)機(ji)(ji)(ji)、模具冷(leng)(leng)(leng)水(shui)機(ji)(ji)(ji)、印刷冷(leng)(leng)(leng)水(shui)機(ji)(ji)(ji)等，而且(qie)大部分(fen)行業(ye)(ye)對(dui)(dui)于(yu)工(gong)(gong)業(ye)(ye)冷(leng)(leng)(leng)水(shui)機(ji)(ji)(ji)要(yao)求(qiu)很高(gao)的(de)，大部分(fen)客(ke)戶的(de)要(yao)求(qiu)都(dou)是24小(xiao)時運轉，所以對(dui)(dui)冷(leng)(leng)(leng)水(shui)機(ji)(ji)(ji)的(de)電(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)壓要(yao)求(qiu)也很高(gao)，如(ru)果冷(leng)(leng)(leng)水(shui)機(ji)(ji)(ji)的(de)幾相(xiang)電(dian)(dian)(dian)壓不平(ping)衡太于(yu)2%時，操作時有(you)可能損壞冷(leng)(leng)(leng)水(shui)機(ji)(ji)(ji)，所以要(yao)控制(zhi)好冷(leng)(leng)(leng)水(shui)機(ji)(ji)(ji)。
冷水機(ji)電源電壓的檢測(ce)
如(ru)果冷水機標準電壓為3相(xiang)，380V，50Hz，測得UAB=376V，UAC=379V，UBC=385V。得出(chu)平均電壓=(376+379+385)/3=380V：確(que)定(ding)與平均電壓的(de)偏(pian)差(cha)(cha)值：△UAB=380-376=4V，△UAC=380-379=1V，△UBC=385-380=5V，最(zui)大偏(pian)差(cha)(cha)值為5V，5/380=1.3%，得出(chu)最(zui)大相(xiang)電壓不(bu)平衡為1.3%。
如果測得該電(dian)源(yuan)和(he)電(dian)壓在正(zheng)(zheng)常(chang)范圍內(nei)，這樣就(jiu)(jiu)可(ke)以(yi)正(zheng)(zheng)常(chang)開機(ji)。如果冷(leng)水機(ji)電(dian)源(yuan)控(kong)制不好(hao)，那么損(sun)壞的(de)話(hua)(hua)就(jiu)(jiu)會(hui)有很高的(de)一個維修成本(ben)，按(an)正(zheng)(zheng)常(chang)來講的(de)話(hua)(hua)電(dian)壓都(dou)會(hui)比較(jiao)正(zheng)(zheng)常(chang)。
冷水機(ji)的電(dian)源電(dian)壓(ya)最大(da)可允許(xu)的相(xiang)電(dian)壓(ya)不(bu)平(ping)衡(heng)(heng)為2%，相(xiang)電(dian)流不(bu)平(ping)衡(heng)(heng)為10%。注：當相(xiang)電(dian)壓(ya)不(bu)平(ping)衡(heng)(heng)大(da)于2%，絕(jue)對不(bu)能(neng)開機(ji)操作。
冷(leng)(leng)(leng)(leng)水(shui)機(ji)的工作(zuo)電(dian)(dian)(dian)源(yuan)是3相，380V，50Hz。在運行(xing)冷(leng)(leng)(leng)(leng)水(shui)機(ji)前，需要檢查電(dian)(dian)(dian)控(kong)(kong)(kong)(kong)柜(ju)中電(dian)(dian)(dian)源(yuan)部分(fen)和控(kong)(kong)(kong)(kong)制(zhi)部分(fen)有無(wu)異常(chang)，并(bing)固(gu)緊接(jie)線端(duan)子(zi)，包括(kuo)總電(dian)(dian)(dian)源(yuan)接(jie)線銅(tong)排，自動(dong)空氣(qi)斷路器(空氣(qi)開關)，Δ-Δ或Y-Δ壓縮(suo)機(ji)啟(qi)動(dong)電(dian)(dian)(dian)氣(qi)裝置，PLC觸摸屏(ping)，靶(ba)流開關，冷(leng)(leng)(leng)(leng)凍水(shui)泵(beng)(beng)，冷(leng)(leng)(leng)(leng)卻(que)水(shui)泵(beng)(beng)聯(lian)動(dong)控(kong)(kong)(kong)(kong)制(zhi)線(控(kong)(kong)(kong)(kong)制(zhi)接(jie)點為(wei)無(wu)源(yuan)接(jie)點)，溫度傳(chuan)感器，冷(leng)(leng)(leng)(leng)凍，冷(leng)(leng)(leng)(leng)卻(que)水(shui)泵(beng)(beng)，冷(leng)(leng)(leng)(leng)卻(que)水(shui)塔(ta)聯(lian)動(dong)控(kong)(kong)(kong)(kong)制(zhi)線(控(kong)(kong)(kong)(kong)制(zhi)接(jie)點為(wei)無(wu)源(yuan)接(jie)點)，電(dian)(dian)(dian)控(kong)(kong)(kong)(kong)儀表(biao)等(deng)等(deng)節(jie)點。待確(que)認好后，方(fang)可(ke)執行(xing)開機(ji)操(cao)作(zuo)，確(que)保冷(leng)(leng)(leng)(leng)水(shui)機(ji)組正(zheng)常(chang)運行(xing)。
