如何檢(jian)查水冷式工業(ye)工業(ye)制冷機的水系統?

1. 檢查水(shui)(shui)冷工(gong)(gong)業工(gong)(gong)業制冷機的冷卻水(shui)(shui)、冷凍水(shui)(shui)管是(shi)(shi)否沖洗干凈，與(yu)外(wai)界連接的冷卻塔(ta)、水(shui)(shui)池(chi)等處是(shi)(shi)否有(you)雜(za)(za)質(zhi)(zhi)。確保存儲過程中(zhong)無雜(za)(za)質(zhi)(zhi)、雜(za)(za)物。檢查水(shui)(shui)側(ce)氣(qi)壓計與(yu)溫度(du)計的連接是(shi)(shi)否正確。氣(qi)壓表應隨水(shui)(shui)管垂直90°安(an)裝。溫度(du)計的安(an)裝應確保其(qi)感溫探頭(tou)插入水(shui)(shui)管中(zhong)。

工業制冷機

工業冷水機組系統的運作是通過三個相互聯系的系統：制冷劑循環系統、 水循環系統、電器自控系統。
制冷劑循環系統
蒸(zheng)發(fa)器中(zhong)的液(ye)態制(zhi)冷(leng)(leng)劑(ji)吸收(shou)水中(zhong)的熱(re)量并開始蒸(zheng)發(fa)，最終制(zhi)冷(leng)(leng)劑(ji)與水之間形成一定的溫(wen)度差(cha)，液(ye)態制(zhi)冷(leng)(leng)劑(ji)亦完(wan)全蒸(zheng)發(fa)變(bian)為氣態，后被壓縮(suo)機吸入并壓縮(suo)（壓力(li)和溫(wen)度增(zeng)加），氣態制(zhi)冷(leng)(leng)劑(ji)通過冷(leng)(leng)凝(ning)器（風冷(leng)(leng)/水冷(leng)(leng)）吸收(shou)熱(re)量，凝(ning)結成液(ye)體。通過膨脹(zhang)閥（或毛(mao)細(xi)管(guan)）節流后變(bian)成低溫(wen)低壓制(zhi)冷(leng)(leng)劑(ji)進入蒸(zheng)發(fa)器，完(wan)成制(zhi)冷(leng)(leng)劑(ji)循環(huan)過程(cheng)。

4. 檢(jian)查水冷工(gong)(gong)業工(gong)(gong)業制冷機冷卻塔/膨脹罐補水裝(zhuang)置是否通(tong)暢(chang)，水系統(tong)自(zi)動排(pai)(pai)氣閥是否能自(zi)動排(pai)(pai)風。如(ru)果是手動排(pai)(pai)氣閥，請打開冷凍水管路(lu)和(he)冷卻水管路(lu)的排(pai)(pai)氣閥，將氣體排(pai)(pai)出。

5. 調節水流，檢查通過(guo)蒸發(fa)器、冷(leng)凝器的水壓降是(shi)否(fou)滿足工(gong)業(ye)(ye)制冷(leng)機(ji)正常運(yun)行的要求(qiu)。即(ji)工(gong)業(ye)(ye)制冷(leng)機(ji)的冷(leng)凍水和冷(leng)卻水的進出口壓力不小(xiao)于0.2MPa。檢查并(bing)確(que)保(bao)水冷(leng)工(gong)業(ye)(ye)工(gong)業(ye)(ye)制冷(leng)機(ji)冷(leng)卻塔風機(ji)等(deng)設施運(yun)行正常，無異常噪聲。檢查風機(ji)皮(pi)(pi)帶松緊是(shi)否(fou)合(he)適(shi)，確(que)保(bao)風機(ji)與電機(ji)之間的連(lian)接皮(pi)(pi)帶不打(da)滑(hua)，運(yun)轉時無異常噪音。
