真空引水系統運行
(1)打開真空引水系統管路上的所有手動球閥、水箱補水管路上的手動球閥。
打開(kai)機封(feng)沖(chong)洗(xi)水(shui)(shui)管道(dao)上(shang)的手(shou)動球閥，為(wei)機封(feng)提供沖(chong)洗(xi)水(shui)(shui)。系統投入(ru)運行后，水(shui)(shui)泵不管是在運行或備(bei)用，機封(feng)沖(chong)洗(xi)水(shui)(shui)必(bi)須常(chang)開(kai)，(真空引(yin)水(shui)(shui))隨時可以(yi)保(bao)證起給水(shui)(shui)泵。
(3)將控制臺(tai)上(shang)的(de)(de)自(zi)動(dong)(dong)-停(ting)(ting)-手動(dong)(dong)調檔(dang)開關調至自(zi)動(dong)(dong)檔(dang)位(wei)(wei)，真(zhen)空(kong)(kong)泵將自(zi)動(dong)(dong)啟(qi)動(dong)(dong)，抽吸水(shui)管(guan)、給水(shui)泵和出水(shui)管(guan)中的(de)(de)氣體，(真(zhen)空(kong)(kong)引水(shui))當(dang)液(ye)位(wei)(wei)達到真(zhen)空(kong)(kong)泵停(ting)(ting)止時(shi)，真(zhen)空(kong)(kong)泵自(zi)動(dong)(dong)停(ting)(ting)機，當(dang)調至手動(dong)(dong)檔(dang)位(wei)(wei)時(shi)，真(zhen)空(kong)(kong)泵將啟(qi)動(dong)(dong)，當(dang)空(kong)(kong)罐(guan)中的(de)(de)水(shui)位(wei)(wei)達到自(zi)動(dong)(dong)檔(dang)位(wei)(wei)止水(shui)時(shi)，需手動(dong)(dong)停(ting)(ting)止真(zhen)空(kong)(kong)泵。正常運(yun)行(xing)時(shi)，檔(dang)位(wei)(wei)定在自(zi)動(dong)(dong)檔(dang)位(wei)(wei)上(shang)，當(dang)真(zhen)空(kong)(kong)罐(guan)中的(de)(de)水(shui)位(wei)(wei)達到啟(qi)動(dong)(dong)的(de)(de)低液(ye)位(wei)(wei)時(shi)，真(zhen)空(kong)(kong)泵就會自(zi)動(dong)(dong)啟(qi)動(dong)(dong)，當(dang)真(zhen)空(kong)(kong)罐(guan)中的(de)(de)水(shui)位(wei)(wei)達到停(ting)(ting)止的(de)(de)高液(ye)位(wei)(wei)時(shi)，真(zhen)空(kong)(kong)泵就會自(zi)動(dong)(dong)停(ting)(ting)止。
(4)根據運行(xing)需要，啟泵(beng)開閥(fa)，給水(shui)泵(beng)投(tou)入運行(xing)。
