隨著(zhu)我(wo)國城市(shi)化的(de)快速(su)發展，住(zhu)宅小(xiao)區的(de)迅速(su)增加(jia)，自來(lai)水(shui)(shui)(shui)管(guan)網的(de)壓力越來(lai)越大，甚至顯得不足，很多(duo)城市(shi)的(de)小(xiao)區在用水(shui)(shui)(shui)的(de)高峰(feng)期(qi)經(jing)常出(chu)現(xian)的(de)斷(duan)水(shui)(shui)(shui)的(de)現(xian)象，俗話說，水(shui)(shui)(shui)是人(ren)類的(de)生(sheng)命之源(yuan)，一旦出(chu)現(xian)斷(duan)水(shui)(shui)(shui)現(xian)象，人(ren)們(men)的(de)基本生(sheng)活都會增加(jia)很多(duo)的(de)麻煩。這時就需要城市(shi)二次(ci)供水(shui)(shui)(shui)設備(bei)來(lai)保障用水(shui)(shui)(shui)，我(wo)們(men)今天就給大家大概介(jie)紹下城市(shi)二次(ci)供水(shui)(shui)(shui)設備(bei)。
城(cheng)市二次供(gong)水(shui)設備是城(cheng)市供(gong)水(shui)的重要組成(cheng)部分，擔負著城(cheng)市供(gong)水(shui)的重要任務。城市二次供(gong)水設備為住(zhu)宅(zhai)必備的(de)供水附屬(shu)設施，主要由泵站(zhan)、入戶管線(xian)、壓力調節設備、蓄水箱、水量計量設備等組(zu)成。
城(cheng)市二次供水(shui)形式
1、水(shui)泵(beng)與水(shui)箱聯(lian)合供(gong)水(shui)形(xing)式(shi)
2、變頻調速供(gong)水形式
3、無負壓供水形(xing)式
從客觀上來分析，恒壓(ya)供(gong)水設備(bei)與城(cheng)市二次供(gong)水設備(bei)各有優缺點(dian)。城(cheng)市二次供(gong)水設備(bei)備(bei)節(jie)能降耗，但(dan)在使用上還(huan)存在一定(ding)的局(ju)限性。恒壓(ya)供(gong)水設備(bei)需(xu)設置低位水箱配合送水。
二(er)次(ci)供(gong)水(shui)設(she)備介(jie)紹
中贏二次供(gong)(gong)水(shui)(shui)(shui)(shui)(shui)(shui)設(she)備通過(guo)微機(ji)控制變頻調(diao)速(su)(su)來實(shi)現恒(heng)(heng)(heng)壓供(gong)(gong)水(shui)(shui)(shui)(shui)(shui)(shui).首先(xian)根據實(shi)際情況設(she)定用(yong)(yong)(yong)(yong)水(shui)(shui)(shui)(shui)(shui)(shui)點工作(zuo)壓力(li)(li)，并時刻(ke)監測市(shi)政(zheng)管網壓力(li)(li)，當(dang)壓力(li)(li)低于用(yong)(yong)(yong)(yong)戶(hu)所(suo)需(xu)壓力(li)(li)時，微機(ji)自動控制子變頻器啟動，調(diao)節(jie)(jie)水(shui)(shui)(shui)(shui)(shui)(shui)泵轉(zhuan)(zhuan)(zhuan)速(su)(su)提高，直(zhi)(zhi)到(dao)管網壓力(li)(li)上(shang)升到(dao)用(yong)(yong)(yong)(yong)戶(hu)所(suo)需(xu)壓力(li)(li)，并控制水(shui)(shui)(shui)(shui)(shui)(shui)泵以一(yi)恒(heng)(heng)(heng)定轉(zhuan)(zhuan)(zhuan)速(su)(su)運(yun)行進行恒(heng)(heng)(heng)壓供(gong)(gong)水(shui)(shui)(shui)(shui)(shui)(shui).當(dang)用(yong)(yong)(yong)(yong)水(shui)(shui)(shui)(shui)(shui)(shui)量增加時轉(zhuan)(zhuan)(zhuan)速(su)(su)提高，當(dang)用(yong)(yong)(yong)(yong)水(shui)(shui)(shui)(shui)(shui)(shui)量減少時轉(zhuan)(zhuan)(zhuan)速(su)(su)降低，時刻(ke)保證用(yong)(yong)(yong)(yong)戶(hu)的(de)(de)(de)用(yong)(yong)(yong)(yong)水(shui)(shui)(shui)(shui)(shui)(shui)壓力(li)(li)恒(heng)(heng)(heng)定.傳統(tong)的(de)(de)(de)城鎮供(gong)(gong)水(shui)(shui)(shui)(shui)(shui)(shui)系統(tong)可以把水(shui)(shui)(shui)(shui)(shui)(shui)廠送水(shui)(shui)(shui)(shui)(shui)(shui)到(dao)用(yong)(yong)(yong)(yong)戶(hu)水(shui)(shui)(shui)(shui)(shui)(shui)龍頭的(de)(de)(de)全過(guo)程(cheng)分離為(wei)一(yi)次供(gong)(gong)水(shui)(shui)(shui)(shui)(shui)(shui)和(he)二次供(gong)(gong)水(shui)(shui)(shui)(shui)(shui)(shui)兩個相對獨立的(de)(de)(de)系統(tong)，而(er)管網直(zhi)(zhi)接(jie)(jie)增壓供(gong)(gong)水(shui)(shui)(shui)(shui)(shui)(shui)系統(tong)是將二者(zhe)結合(he)成為(wei)一(yi)個整體的(de)(de)(de)系統(tong)，變二次供(gong)(gong)水(shui)(shui)(shui)(shui)(shui)(shui)為(wei)一(yi)次直(zhi)(zhi)接(jie)(jie)供(gong)(gong)水(shui)(shui)(shui)(shui)(shui)(shui)到(dao)戶(hu).無負壓給水(shui)(shui)(shui)(shui)(shui)(shui)設(she)備則(ze)是管網直(zhi)(zhi)接(jie)(jie)增壓供(gong)(gong)水(shui)(shui)(shui)(shui)(shui)(shui)系統(tong)可以使(shi)用(yong)(yong)(yong)(yong)的(de)(de)(de)設(she)備.直(zhi)(zhi)接(jie)(jie)以市(shi)政(zheng)管網為(wei)水(shui)(shui)(shui)(shui)(shui)(shui)源、形(xing)成連續密閉的(de)(de)(de)接(jie)(jie)力(li)(li)增壓供(gong)(gong)水(shui)(shui)(shui)(shui)(shui)(shui)方式，徹底避免了(le)傳統(tong)2次增壓供(gong)(gong)水(shui)(shui)(shui)(shui)(shui)(shui)系統(tong)造成的(de)(de)(de)水(shui)(shui)(shui)(shui)(shui)(shui)質標準降低和(he)各種(zhong)水(shui)(shui)(shui)(shui)(shui)(shui)源污染問題，完全保持了(le)市(shi)政(zheng)水(shui)(shui)(shui)(shui)(shui)(shui)源的(de)(de)(de)水(shui)(shui)(shui)(shui)(shui)(shui)質標準充分利(li)用(yong)(yong)(yong)(yong)市(shi)政(zheng)水(shui)(shui)(shui)(shui)(shui)(shui)源本(ben)身壓力(li)(li)熱能，差多少補(bu)多少，切實(shi)有效(xiao)地、最大(da)限度地發揮(hui)了(le)變頻調(diao)速(su)(su)的(de)(de)(de)節(jie)(jie)能效(xiao)果。
