箱式供水設備的工作原理
自(zi)來(lai)(lai)水(shui)(shui)(shui)(shui)進入調節罐(guan)，罐(guan)中(zhong)(zhong)的(de)(de)空氣(qi)從(cong)真空消(xiao)除器(qi)(qi)排(pai)出(chu)。注滿(man)水(shui)(shui)(shui)(shui)后，真空消(xiao)除器(qi)(qi)自(zi)動關(guan)閉(bi)。當自(zi)來(lai)(lai)水(shui)(shui)(shui)(shui)能(neng)夠滿(man)足(zu)水(shui)(shui)(shui)(shui)壓和(he)水(shui)(shui)(shui)(shui)量(liang)要求(qiu)時(shi)，設備通過(guo)旁路止回閥直接向(xiang)水(shui)(shui)(shui)(shui)管(guan)網(wang)(wang)(wang)供(gong)(gong)(gong)水(shui)(shui)(shui)(shui)；當水(shui)(shui)(shui)(shui)管(guan)網(wang)(wang)(wang)的(de)(de)壓力(li)(li)不能(neng)滿(man)足(zu)用水(shui)(shui)(shui)(shui)需(xu)求(qiu)時(shi)，系統(tong)通過(guo)壓力(li)(li)傳感器(qi)(qi)(或壓力(li)(li)控制(zhi)器(qi)(qi)、電接點壓力(li)(li)表)啟(qi)動泵(beng)運行信號。當供(gong)(gong)(gong)水(shui)(shui)(shui)(shui)被泵(beng)送時(shi)，如果(guo)水(shui)(shui)(shui)(shui)管(guan)網(wang)(wang)(wang)的(de)(de)水(shui)(shui)(shui)(shui)流大于泵(beng)的(de)(de)水(shui)(shui)(shui)(shui)流，系統(tong)保(bao)持正常供(gong)(gong)(gong)水(shui)(shui)(shui)(shui)；在高峰期，當水(shui)(shui)(shui)(shui)管(guan)網(wang)(wang)(wang)的(de)(de)水(shui)(shui)(shui)(shui)流量(liang)小于泵(beng)的(de)(de)流量(liang)時(shi)，調節池中(zhong)(zhong)的(de)(de)水(shui)(shui)(shui)(shui)仍然可(ke)以供(gong)(gong)(gong)應正常的(de)(de)水(shui)(shui)(shui)(shui)作為補(bu)充水(shui)(shui)(shui)(shui)源。這時(shi)，空氣(qi)從(cong)真空消(xiao)除器(qi)(qi)進入調節罐(guan)，消(xiao)除了水(shui)(shui)(shui)(shui)管(guan)網(wang)(wang)(wang)。高峰期過(guo)后，系統(tong)恢復正常。如果(guo)自(zi)來(lai)(lai)水(shui)(shui)(shui)(shui)供(gong)(gong)(gong)應不足(zu)或由于管(guan)網(wang)(wang)(wang)停水(shui)(shui)(shui)(shui)導致調節池中(zhong)(zhong)的(de)(de)水(shui)(shui)(shui)(shui)位(wei)持續(xu)下(xia)降，水(shui)(shui)(shui)(shui)位(wei)檢測(ce)器(qi)(qi)會(hui)發出(chu)停泵(beng)信號以保(bao)護泵(beng)機組。夜間(jian)供(gong)(gong)(gong)水(shui)(shui)(shui)(shui)和(he)小流量(liang)可(ke)由小膨脹水(shui)(shui)(shui)(shui)箱提(ti)供(gong)(gong)(gong)，以防止泵(beng)頻繁啟(qi)動。
