防爆型冰水機

(如果冷(leng)水(shui)(shui)機配(pei)有壓(ya)(ya)(ya)力表，高壓(ya)(ya)(ya)表的(de)壓(ya)(ya)(ya)力是(shi)否高于(yu)(yu)300psi，如果高于(yu)(yu)，清(qing)洗(xi)(xi)散(san)(san)熱器(qi)外觀，堅(jian)持清(qing)洗(xi)(xi)，提高散(san)(san)熱器(qi)的(de)功(gong)能(neng)(neng)。如按以上指(zhi)示反復(fu)清(qing)洗(xi)(xi)后仍有問題(ti)，請組織(zhi)工(gong)作(zuo)(zuo)人(ren)員(yuan)進行維修。如果停(ting)一段時間，由(you)于(yu)(yu)水(shui)(shui)和污水(shui)(shui)沉(chen)淀物的(de)凝結，水(shui)(shui)泵(beng)葉片(pian)可能(neng)(neng)被污水(shui)(shui)沉(chen)淀物凝結。再次啟(qi)動(dong)時，必須先松開泵(beng)轉(zhuan)子(zi)，避免泵(beng)葉片(pian)不轉(zhuan)動(dong)，導致保(bao)險絲燒壞。冷(leng)水(shui)(shui)機維護(hu)。在清(qing)洗(xi)(xi)暖氣(qi)片(pian)之前(qian)(qian)先停(ting)車。取下機器(qi)前(qian)(qian)下面板上的(de)濾(lv)網，用壓(ya)(ya)(ya)縮空氣(qi)吹去濾(lv)網表面的(de)灰(hui)塵。如果暖氣(qi)片(pian)臟(zang)了，也要一起(qi)清(qing)洗(xi)(xi)。如果可能(neng)(neng)，將空調清(qing)洗(xi)(xi)劑噴在散(san)(san)熱網上，等待幾分(fen)鐘后，用清(qing)水(shui)(shui)清(qing)洗(xi)(xi)，重復(fu)操作(zuo)(zuo)，直到過(guo)濾(lv)網外觀清(qing)潔。

   截止(zhi)閥(fa)的(de)選型和配置(zhi)(zhi)主(zhu)要基于工(gong)(gong)(gong)業冷卻(que)機(ji)(ji)設備(bei)的(de)運行(xing)工(gong)(gong)(gong)況，即常用(yong)(yong)(yong)的(de)溫(wen)度(du)和壓(ya)(ya)縮(suo)機(ji)(ji)的(de)功(gong)率。家用(yong)(yong)(yong)空調(diao)和小型工(gong)(gong)(gong)業冷卻(que)機(ji)(ji)設備(bei)通常使用(yong)(yong)(yong)毛(mao)(mao)細管(guan)作(zuo)(zuo)為截流(liu)器(qi)，毛(mao)(mao)細管(guan)的(de)直(zhi)徑(jing)和長度(du)要根據(ju)壓(ya)(ya)縮(suo)機(ji)(ji)的(de)功(gong)率和工(gong)(gong)(gong)作(zuo)(zuo)溫(wen)度(du)來確(que)定。原則上，功(gong)率越小，毛(mao)(mao)細管(guan)越長，口(kou)(kou)徑(jing)越小，工(gong)(gong)(gong)作(zuo)(zuo)溫(wen)度(du)越低，毛(mao)(mao)細管(guan)就越長。其他型號(hao)通常使用(yong)(yong)(yong)膨(peng)脹(zhang)(zhang)閥(fa)作(zuo)(zuo)為截流(liu)裝(zhuang)(zhuang)置(zhi)(zhi)。膨(peng)脹(zhang)(zhang)閥(fa)分為外部(bu)平衡(heng)閥(fa)、內(nei)部(bu)平衡(heng)閥(fa)和電(dian)子(zi)(zi)膨(peng)脹(zhang)(zhang)閥(fa)。外部(bu)平衡(heng)是最(zui)廣(guang)泛的(de)一個。通過檢測低壓(ya)(ya)回端溫(wen)度(du)，自動(dong)調(diao)節(jie)閥(fa)門(men)(men)開度(du)，達(da)到(dao)佳制冷效果，內(nei)部(bu)平衡(heng)多采用(yong)(yong)(yong)低溫(wen)、超低溫(wen)低溫(wen)裝(zhuang)(zhuang)置(zhi)(zhi)。閥(fa)門(men)(men)的(de)尺(chi)寸通過內(nei)置(zhi)(zhi)的(de)壓(ya)(ya)力平衡(heng)管(guan)進行(xing)調(diao)整(zheng)(zheng)。電(dian)子(zi)(zi)膨(peng)脹(zhang)(zhang)主(zhu)要用(yong)(yong)(yong)于變頻機(ji)(ji)組，根據(ju)設定的(de)溫(wen)度(du)和工(gong)(gong)(gong)作(zuo)(zuo)條件(jian)來調(diao)整(zheng)(zheng)壓(ya)(ya)縮(suo)機(ji)(ji)的(de)工(gong)(gong)(gong)作(zuo)(zuo)頻率。還(huan)安裝(zhuang)(zhuang)了電(dian)子(zi)(zi)膨(peng)脹(zhang)(zhang)裝(zhuang)(zhuang)置(zhi)(zhi)，根據(ju)控制系統(tong)的(de)數據(ju)反饋和蒸(zheng)發器(qi)進出口(kou)(kou)的(de)過熱，自動(dong)調(diao)節(jie)開啟度(du)
