制冷設備冷水(shui)機的功(gong)能
制冷(leng)設備冷(leng)水(shui)機所(suo)起的作(zuo)用是,提供(gong)工(gong)業冷(leng)凍水(shui)給設備降溫,以產品質量的穩定,提升(sheng)整個工(gong)廠的生(sheng)產效率.在(zai)現代社會,制冷(leng)設備冷(leng)水(shui)機已經幾乎滲透到各個生(sheng)產技術(shu)(shu),科學(xue)研究領域(yu),并在(zai)改善人類的生(sheng)活(huo)(huo)質量方(fang)面發(fa)揮巨大作(zuo)用.制冷(leng)設備冷(leng)水(shui)機在(zai)工(gong)業生(sheng)產中(zhong)，為(wei)生(sheng)產環境(jing)提供(gong)必要的恒溫環境(jing)，對材(cai)(cai)料進行低溫處理.生(sheng)活(huo)(huo)中(zhong),廣泛(fan)用于食(shi)品冷(leng)加工(gong),冷(leng)貯藏,冷(leng)藏運(yun)輸.制冷(leng)設備冷(leng)水(shui)機在(zai)科學(xue)領域(yu)如(ru)新型材(cai)(cai)料,生(sheng)物(wu)技術(shu)(shu)的研究和開發(fa)中(zhong)起著舉足輕重的作(zuo)用.
制冷(leng)設備(bei)冷(leng)水機的原則：
在滿足設備和(he)(he)生產(chan)需求的前提(ti)下降低(di)冷(leng)(leng)(leng)凝溫度.盡量提(ti)高蒸(zheng)發溫度和(he)(he)降低(di)冷(leng)(leng)(leng)凝溫度,為此加大了(le)冷(leng)(leng)(leng)卻塔的改造,以(yi)冷(leng)(leng)(leng)卻水效(xiao)能.制冷(leng)(leng)(leng)設備冷(leng)(leng)(leng)水機防止,減少管(guan)道(dao)結垢,以(yi)提(ti)高冷(leng)(leng)(leng)凝器(qi)(qi)和(he)(he)蒸(zheng)發器(qi)(qi)的換熱(re)(re)效(xiao)率,如(ru)果(guo)水處理做的不(bu)好,碳(tan)酸(suan)(suan)氫(qing)鈣和(he)(he)碳(tan)酸(suan)(suan)氫(qing)鎂,受(shou)熱(re)(re)產(chan)生碳(tan)酸(suan)(suan)鈣和(he)(he)碳(tan)酸(suan)(suan)鎂會(hui)沉積在管(guan)道(dao)上(shang),使導熱(re)(re)性能下降,影響冷(leng)(leng)(leng)凝器(qi)(qi)和(he)(he)蒸(zheng)發器(qi)(qi)的換熱(re)(re)效(xiao)率,并使設備運行(xing)電費大幅度上(shang)升.此時除了(le)采用水處理技術外.還可以(yi)利用管(guan)道(dao)定期自動清洗設備進行(xing)管(guan)道(dao)清洗.
制冷設(she)備冷水機(ji)啟(qi)動前應先做(zuo)好以下(xia)工作:
首先檢(jian)查電(dian)(dian)源(yuan)是(shi)(shi)(shi)否(fou)正(zheng)常,電(dian)(dian)源(yuan)電(dian)(dian)壓(ya)(ya)不(bu)應(ying)超(chao)過(guo)(guo)或(huo)低于機組(zu)額定電(dian)(dian)壓(ya)(ya)的(de)±10%,常用(yong)的(de)電(dian)(dian)壓(ya)(ya)有(you)3相380V,單相220V,當電(dian)(dian)壓(ya)(ya)過(guo)(guo)低或(huo)過(guo)(guo)高(gao)時,不(bu)能啟動冷水(shui)(shui)機.有(you)水(shui)(shui)系統的(de)壓(ya)(ya)縮機組(zu),仔細檢(jian)查冷卻水(shui)(shui)系統和冷凍水(shui)(shui)系統是(shi)(shi)(shi)否(fou)有(you)水(shui)(shui),水(shui)(shui)壓(ya)(ya)是(shi)(shi)(shi)否(fou)正(zheng)常,冷卻水(shui)(shui),冷凍水(shui)(shui)的(de)管(guan)路系統是(shi)(shi)(shi)否(fou)暢通.檢(jian)查制冷設備冷水(shui)(shui)機的(de)各(ge)種(zhong)壓(ya)(ya)力表,溫度計,流(liu)量(liang)計,電(dian)(dian)磁閥(fa),繼電(dian)(dian)器,能量(liang)調節閥(fa)是(shi)(shi)(shi)否(fou)完(wan)好未失(shi)靈(ling).制冷設備在使(shi)用(yong)過(guo)(guo)程(cheng)中(zhong),要仔細觀察并(bing)傾聽機組(zu)各(ge)部件發出的(de)聲音及異常,并(bing)定期對冷水(shui)(shui)機組(zu)做(zuo)維護保養工作(zuo),長(chang)時間不(bu)使(shi)用(yong)機組(zu)時,應(ying)排干凈管(guan)路的(de)水(shui)(shui),并(bing)用(yong)物品遮蓋(gai)住機組(zu)等.
