(如(ru)(ru)果冷(leng)水機(ji)配有(you)壓(ya)力表(biao)，高(gao)壓(ya)表(biao)的(de)壓(ya)力是否高(gao)于300psi，如(ru)(ru)果高(gao)于，清(qing)(qing)洗散熱器(qi)(qi)外觀(guan)，堅持清(qing)(qing)洗，提高(gao)散熱器(qi)(qi)的(de)功能。如(ru)(ru)按以上(shang)指示反(fan)復(fu)清(qing)(qing)洗后仍(reng)有(you)問題(ti)，請組(zu)織工作(zuo)人員進行(xing)維修(xiu)。如(ru)(ru)果停一段時間，由于水和污水沉淀(dian)物的(de)凝(ning)結，水泵葉片(pian)可能被污水沉淀(dian)物凝(ning)結。再次啟動時，必須(xu)先(xian)松開泵轉(zhuan)子，避免(mian)泵葉片(pian)不轉(zhuan)動，導致(zhi)保險絲燒壞。冷(leng)水機(ji)維護。在清(qing)(qing)洗暖氣片(pian)之前先(xian)停車(che)。取(qu)下(xia)機(ji)器(qi)(qi)前下(xia)面板上(shang)的(de)濾網，用壓(ya)縮空氣吹去(qu)濾網表(biao)面的(de)灰塵(chen)。如(ru)(ru)果暖氣片(pian)臟了，也(ye)要一起清(qing)(qing)洗。如(ru)(ru)果可能，將空調清(qing)(qing)洗劑噴在散熱網上(shang)，等待幾(ji)分鐘后，用清(qing)(qing)水清(qing)(qing)洗，重復(fu)操作(zuo)，直(zhi)到(dao)過濾網外觀(guan)清(qing)(qing)潔(jie)。

   截止閥(fa)(fa)(fa)的(de)選型(xing)和(he)(he)(he)配置(zhi)主(zhu)要基于工(gong)(gong)(gong)(gong)業冷(leng)卻機(ji)設備的(de)運行(xing)工(gong)(gong)(gong)(gong)況，即(ji)常(chang)(chang)(chang)用(yong)的(de)溫(wen)(wen)(wen)(wen)度(du)(du)(du)和(he)(he)(he)壓(ya)縮(suo)機(ji)的(de)功率(lv)。家用(yong)空調和(he)(he)(he)小(xiao)(xiao)型(xing)工(gong)(gong)(gong)(gong)業冷(leng)卻機(ji)設備通(tong)常(chang)(chang)(chang)使用(yong)毛(mao)細管作(zuo)為截流器(qi)，毛(mao)細管的(de)直徑(jing)和(he)(he)(he)長度(du)(du)(du)要根(gen)據壓(ya)縮(suo)機(ji)的(de)功率(lv)和(he)(he)(he)工(gong)(gong)(gong)(gong)作(zuo)溫(wen)(wen)(wen)(wen)度(du)(du)(du)來(lai)確(que)定(ding)。原則上，功率(lv)越小(xiao)(xiao)，毛(mao)細管越長，口徑(jing)越小(xiao)(xiao)，工(gong)(gong)(gong)(gong)作(zuo)溫(wen)(wen)(wen)(wen)度(du)(du)(du)越低(di)(di)，毛(mao)細管就越長。其他型(xing)號(hao)通(tong)常(chang)(chang)(chang)使用(yong)膨脹閥(fa)(fa)(fa)作(zuo)為截流裝置(zhi)。膨脹閥(fa)(fa)(fa)分為外部(bu)平(ping)(ping)(ping)衡(heng)閥(fa)(fa)(fa)、內部(bu)平(ping)(ping)(ping)衡(heng)閥(fa)(fa)(fa)和(he)(he)(he)電子(zi)膨脹閥(fa)(fa)(fa)。外部(bu)平(ping)(ping)(ping)衡(heng)是最廣泛(fan)的(de)一個。通(tong)過檢(jian)測低(di)(di)壓(ya)回端溫(wen)(wen)(wen)(wen)度(du)(du)(du)，自動(dong)調節閥(fa)(fa)(fa)門開(kai)度(du)(du)(du)，達到佳制冷(leng)效果，內部(bu)平(ping)(ping)(ping)衡(heng)多采(cai)用(yong)低(di)(di)溫(wen)(wen)(wen)(wen)、超(chao)低(di)(di)溫(wen)(wen)(wen)(wen)低(di)(di)溫(wen)(wen)(wen)(wen)裝置(zhi)。閥(fa)(fa)(fa)門的(de)尺(chi)寸(cun)通(tong)過內置(zhi)的(de)壓(ya)力平(ping)(ping)(ping)衡(heng)管進行(xing)調整。電子(zi)膨脹主(zhu)要用(yong)于變頻機(ji)組(zu)，根(gen)據設定(ding)的(de)溫(wen)(wen)(wen)(wen)度(du)(du)(du)和(he)(he)(he)工(gong)(gong)(gong)(gong)作(zuo)條件來(lai)調整壓(ya)縮(suo)機(ji)的(de)工(gong)(gong)(gong)(gong)作(zuo)頻率(lv)。還安裝了電子(zi)膨脹裝置(zhi)，根(gen)據控制系統(tong)的(de)數據反饋和(he)(he)(he)蒸(zheng)發器(qi)進出口的(de)過熱，自動(dong)調節開(kai)啟(qi)度(du)(du)(du)
