無負壓供水裝置工作原理

     設(she)備正常投(tou)入使用時(shi)，市(shi)政(zheng)管網的水進入無負壓穩流罐(guan)，罐(guan)內(nei)的空(kong)氣(qi)從排(pai)(pai)氣(qi)閥(fa)大(da)量(liang)排(pai)(pai)出。當(dang)空(kong)氣(qi)排(pai)(pai)完時(shi)，閥(fa)內(nei)浮(fu)球被除水浮(fu)起，傳動塞頭(tou)至關閉(bi)位置(zhi)，慢慢關閉(bi)排(pai)(pai)氣(qi)口，停止排(pai)(pai)氣(qi)，防止出水，當(dang)穩流罐(guan)內(nei)水流正常輸送時(shi)，如有少量(liang)空(kong)氣(qi)聚集在閥(fa)內(nei)到相當(dang)程度，閥(fa)內(nei)水位下降，浮(fu)球隨之下降，此時(shi)空(kong)氣(qi)則由排(pai)(pai)氣(qi)孔排(pai)(pai)出。

     無負(fu)壓(ya)(ya)供水(shui)裝置正常運行(xing)過程中，當市(shi)政(zheng)管網供水(shui)量(liang)不足時(shi)，市(shi)政(zheng)進(jin)水(shui)管管內水(shui)流(liu)空(kong)時(shi)，或穩流(liu)罐(guan)內水(shui)壓(ya)(ya)低于(yu)大(da)氣(qi)壓(ya)(ya)時(shi)，穩流(liu)罐(guan)內水(shui)位下降，浮(fu)球隨之下降，帶動(dong)塞(sai)頭開啟，吸入空(kong)氣(qi)，使穩流(liu)罐(guan)內保(bao)持大(da)氣(qi)壓(ya)(ya)力(li)，不至對市(shi)政(zheng)管網產生負(fu)壓(ya)(ya)。

     當市政(zheng)管網(wang)(wang)中(zhong)壓力(li)低(di)(di)于用(yong)戶所需(xu)的(de)設定壓力(li)時，水(shui)(shui)泵(beng)變頻(pin)調速運行，保證用(yong)戶管網(wang)(wang)壓力(li)符合用(yong)戶用(yong)水(shui)(shui)的(de)要(yao)求。市政(zheng)管網(wang)(wang)水(shui)(shui)壓越(yue)高(gao)。水(shui)(shui)泵(beng)的(de)轉(zhuan)速越(yue)低(di)(di)，市政(zheng)管網(wang)(wang)水(shui)(shui)壓越(yue)低(di)(di)，水(shui)(shui)泵(beng)的(de)轉(zhuan)速越(yue)高(gao)。當市政(zheng)管網(wang)(wang)供水(shui)(shui)壓力(li)達到用(yong)戶要(yao)求時，設備自動(dong)停止工作，市政(zheng)管網(wang)(wang)的(de)水(shui)(shui)通過旁通管直接(jie)供給用(yong)戶使(shi)用(yong)。

     當市(shi)政管(guan)網停水時，穩流(liu)罐內水位逐(zhu)漸(jian)下(xia)降，當降至較(jiao)低水位時，穩流(liu)罐上的(de)液位計(ji)發出停機信號(hao)，設備(bei)自動停止運行并顯示缺(que)水保護信號(hao)。

     當電網(wang)(wang)停電時，設備(bei)停機，市政管網(wang)(wang)的水直接(jie)從(cong)設備(bei)旁通管供應到(dao)用戶。
