確認(ren)工(gong)業(ye)冷(leng)(leng)水(shui)(shui)機供(gong)電(dian)正(zheng)常，無(wu)反(fan)相(xiang)(xiang)、缺相(xiang)(xiang)現象;冷(leng)(leng)卻塔風機、冷(leng)(leng)卻水(shui)(shui)泵、冷(leng)(leng)凍水(shui)(shui)泵均為(wei)獨立控制。開機前(qian)應確認(ren)電(dian)源(yuan)正(zheng)常，無(wu)反(fan)相(xiang)(xiang)、缺相(xiang)(xiang)現象。檢(jian)查工(gong)業(ye)冷(leng)(leng)水(shui)(shui)機主(zhu)機、水(shui)(shui)泵、閥(fa)門、儀表及各種附件是否能夠打開，是否完好。檢(jian)查工(gong)業(ye)冷(leng)(leng)水(shui)(shui)機組(zu)油(you)位是否正(zheng)常(應在(zai)下(xia)鏡中心線以(yi)上(shang)(shang)，上(shang)(shang)鏡中心線以(yi)下(xia))

   開機(ji)前12小時接通冷(leng)水(shui)機(ji)組電(dian)(dian)源，使油加熱(re)器順利電(dian)(dian)加熱(re);啟動冷(leng)水(shui)機(ji)前，先對(dui)冷(leng)凍(dong)水(shui)循環系(xi)統和冷(leng)卻水(shui)循環系(xi)統進行調試;檢查制冷(leng)系(xi)統壓力(li)表讀數(shu)是否等于制冷(leng)劑在當地環境(jing)溫度下的(de)飽和壓力(li)值(zhi);檢查壓縮機(ji)電(dian)(dian)機(ji)絕(jue)緣(yuan)電(dian)(dian)阻，絕(jue)緣(yuan)電(dian)(dian)阻應在3兆歐以上。
