蘭州久華二次供(gong)水(shui)設(she)備(bei)(bei)(bei)采用氣(qi)(qi)壓(ya)(ya)式供(gong)水(shui)。利用密封罐(guan)體(ti)(ti)，利用罐(guan)內高(gao)壓(ya)(ya)氣(qi)(qi)水(shui)壓(ya)(ya)力(li)達到(dao)供(gong)水(shui)目(mu)的(de)。具體(ti)(ti)工作順序(xu)是由水(shui)泵(beng)將水(shui)通過逆(ni)止閥壓(ya)(ya)入罐(guan)體(ti)(ti)，使(shi)(shi)(shi)罐(guan)內氣(qi)(qi)體(ti)(ti)受到(dao)壓(ya)(ya)縮，壓(ya)(ya)力(li)逐漸增大(da)。當(dang)壓(ya)(ya)力(li)達到(dao)指(zhi)定上限時電接(jie)點壓(ya)(ya)力(li)表通過控制柜(ju)使(shi)(shi)(shi)泵(beng)機(ji)自動(dong)停(ting)止。設(she)備(bei)(bei)(bei)中(zhong)的(de)水(shui)壓(ya)(ya)高(gao)于外界管網(wang)壓(ya)(ya)力(li)，自動(dong)送(song)水(shui)至供(gong)水(shui)管網(wang)。當(dang)罐(guan)體(ti)(ti)內水(shui)位下降，罐(guan)內氣(qi)(qi)體(ti)(ti)膨漲壓(ya)(ya)力(li)減(jian)小到(dao)指(zhi)定的(de)下限位置(zhi)時，電接(jie)點壓(ya)(ya)力(li)表通過控制柜(ju)使(shi)(shi)(shi)水(shui)泵(beng)重新啟(qi)動(dong)。如此反復，使(shi)(shi)(shi)設(she)備(bei)(bei)(bei)不停(ting)供(gong)水(shui)。當(dang)罐(guan)內氣(qi)(qi)體(ti)(ti)不足時，補氣(qi)(qi)閥可自動(dong)補氣(qi)(qi)。
