一、緩沖罐的作用
緩沖罐主(zhu)要(yao)(yao)用(yong)于各(ge)種系(xi)(xi)統(tong)中緩沖系(xi)(xi)統(tong)的壓(ya)力波動(dong),使系(xi)(xi)統(tong)工(gong)作更(geng)平穩(wen)。緩沖罐的緩沖性能(neng)主(zhu)要(yao)(yao)通過壓(ya)縮罐內的壓(ya)縮空氣來(lai)實現。緩沖罐有(you)隔膜(mo)式(shi)緩沖罐和氣囊式(shi)兩(liang)種,被廣泛應用(yong)于中央空調、鍋爐、熱水器、變(bian)頻、恒(heng)壓(ya)供(gong)水設備中,其緩沖系(xi)(xi)統(tong)壓(ya)力波動(dong),消除水錘起到穩(wen)壓(ya)卸荷的作用(yong),在系(xi)(xi)統(tong)內水壓(ya)輕微變(bian)化(hua)時,緩沖罐氣囊的自(zi)動(dong)膨(peng)脹收縮會(hui)對水壓(ya)的變(bian)化(hua)有(you)一(yi)定(ding)緩沖作用(yong),能(neng)保證系(xi)(xi)統(tong)的水壓(ya)穩(wen)定(ding),水泵不會(hui)因壓(ya)力的改變(bian)而頻繁的開啟。
二、緩沖罐的結構和工作原理
緩沖罐(guan)是利用(yong)液(ye)體(ti)(ti)的(de)壓(ya)(ya)縮(suo)性極小(xiao)的(de)性質,用(yong)外力(li)將液(ye)體(ti)(ti)儲存在罐(guan)內,氣(qi)(qi)體(ti)(ti)受(shou)到壓(ya)(ya)縮(suo)壓(ya)(ya)力(li)升高(gao),當外力(li)消失(shi)壓(ya)(ya)縮(suo)氣(qi)(qi)體(ti)(ti)膨脹可將水排除。
緩(huan)沖(chong)(chong)罐(guan)(guan)主要由氣(qi)(qi)(qi)(qi)門蓋、充氣(qi)(qi)(qi)(qi)口、氣(qi)(qi)(qi)(qi)囊(nang)(nang)(nang)(nang)、碳(tan)鋼(gang)罐(guan)(guan)體(ti)(ti)(ti)、法蘭盤組成,當其(qi)連(lian)接到(dao)水(shui)(shui)(shui)系(xi)(xi)(xi)統(tong)(tong)(tong)上時(shi)(shi),主要起一(yi)個蓄能器的(de)作(zuo)(zuo)用(yong)(yong)(yong),當系(xi)(xi)(xi)統(tong)(tong)(tong)水(shui)(shui)(shui)壓(ya)(ya)(ya)(ya)力(li)(li)(li)大于(yu)(yu)緩(huan)沖(chong)(chong)罐(guan)(guan)碳(tan)鋼(gang)罐(guan)(guan)體(ti)(ti)(ti)于(yu)(yu)氣(qi)(qi)(qi)(qi)囊(nang)(nang)(nang)(nang)之(zhi)間的(de)氣(qi)(qi)(qi)(qi)壓(ya)(ya)(ya)(ya)力(li)(li)(li)時(shi)(shi),系(xi)(xi)(xi)統(tong)(tong)(tong)水(shui)(shui)(shui)會(hui)在系(xi)(xi)(xi)統(tong)(tong)(tong)壓(ya)(ya)(ya)(ya)力(li)(li)(li)的(de)作(zuo)(zuo)用(yong)(yong)(yong)下(xia)擠入緩(huan)沖(chong)(chong)罐(guan)(guan)氣(qi)(qi)(qi)(qi)囊(nang)(nang)(nang)(nang)內(nei),這樣一(yi)是(shi)會(hui)壓(ya)(ya)(ya)(ya)縮罐(guan)(guan)體(ti)(ti)(ti)于(yu)(yu)氣(qi)(qi)(qi)(qi)囊(nang)(nang)(nang)(nang)之(zhi)間的(de)氣(qi)(qi)(qi)(qi),使其(qi)體(ti)(ti)(ti)積(ji)減小(xiao)(xiao),壓(ya)(ya)(ya)(ya)力(li)(li)(li)增大;罐(guan)(guan)體(ti)(ti)(ti)于(yu)(yu)氣(qi)(qi)(qi)(qi)囊(nang)(nang)(nang)(nang)之(zhi)間是(shi)出(chu)廠時(shi)(shi)預充的(de)氣(qi)(qi)(qi)(qi),罐(guan)(guan)體(ti)(ti)(ti)外面為(wei)烤(kao)漆(qi)層(ceng),進(jin)出(chu)水(shui)(shui)(shui)口直(zhi)接用(yong)(yong)(yong)三通或金屬軟管連(lian)接到(dao)系(xi)(xi)(xi)統(tong)(tong)(tong),排(pai)氣(qi)(qi)(qi)(qi)閥(fa)(fa)接口可及(ji)時(shi)(shi)排(pai)出(chu)系(xi)(xi)(xi)統(tong)(tong)(tong)和氣(qi)(qi)(qi)(qi)囊(nang)(nang)(nang)(nang)內(nei)的(de)水(shui)(shui)(shui)溢出(chu)的(de)空(kong)氣(qi)(qi)(qi)(qi),也可用(yong)(yong)(yong)閘(zha)閥(fa)(fa)直(zhi)接關死(si),以免(mian)水(shui)(shui)(shui)從頂(ding)部溢出(chu),防塵帽下(xia)面是(shi)充/放(fang)氣(qi)(qi)(qi)(qi)口,可補(bu)充氣(qi)(qi)(qi)(qi)或放(fang)掉一(yi)部分氣(qi)(qi)(qi)(qi)體(ti)(ti)(ti)。二是(shi)會(hui)增加系(xi)(xi)(xi)統(tong)(tong)(tong)整個水(shui)(shui)(shui)的(de)容(rong)納空(kong)間,使系(xi)(xi)(xi)統(tong)(tong)(tong)壓(ya)(ya)(ya)(ya)力(li)(li)(li)減小(xiao)(xiao),直(zhi)到(dao)系(xi)(xi)(xi)統(tong)(tong)(tong)水(shui)(shui)(shui)的(de)壓(ya)(ya)(ya)(ya)力(li)(li)(li)和罐(guan)(guan)體(ti)(ti)(ti)于(yu)(yu)氣(qi)(qi)(qi)(qi)囊(nang)(nang)(nang)(nang)之(zhi)間的(de)氣(qi)(qi)(qi)(qi)壓(ya)(ya)(ya)(ya)力(li)(li)(li)達(da)到(dao)新的(de)平衡才停止進(jin)水(shui)(shui)(shui)。當系(xi)(xi)(xi)統(tong)(tong)(tong)水(shui)(shui)(shui)壓(ya)(ya)(ya)(ya)力(li)(li)(li)小(xiao)(xiao)于(yu)(yu)膨脹罐(guan)(guan)內(nei)氣(qi)(qi)(qi)(qi)體(ti)(ti)(ti)壓(ya)(ya)(ya)(ya)力(li)(li)(li)時(shi)(shi),氣(qi)(qi)(qi)(qi)囊(nang)(nang)(nang)(nang)內(nei)的(de)水(shui)(shui)(shui)會(hui)在罐(guan)(guan)體(ti)(ti)(ti)于(yu)(yu)氣(qi)(qi)(qi)(qi)囊(nang)(nang)(nang)(nang)之(zhi)間的(de)氮(dan)氣(qi)(qi)(qi)(qi)的(de)壓(ya)(ya)(ya)(ya)力(li)(li)(li)作(zuo)(zuo)用(yong)(yong)(yong)下(xia)擠出(chu),補(bu)回(hui)到(dao)系(xi)(xi)(xi)統(tong)(tong)(tong),系(xi)(xi)(xi)統(tong)(tong)(tong)水(shui)(shui)(shui)容(rong)積(ji)減小(xiao)(xiao)壓(ya)(ya)(ya)(ya)力(li)(li)(li)上升,罐(guan)(guan)體(ti)(ti)(ti)于(yu)(yu)氣(qi)(qi)(qi)(qi)囊(nang)(nang)(nang)(nang)之(zhi)間的(de)氣(qi)(qi)(qi)(qi)體(ti)(ti)(ti)積(ji)增大壓(ya)(ya)(ya)(ya)力(li)(li)(li)下(xia)降,直(zhi)到(dao)兩(liang)者達(da)到(dao)新的(de)平衡,水(shui)(shui)(shui)停止從氣(qi)(qi)(qi)(qi)囊(nang)(nang)(nang)(nang)擠壓(ya)(ya)(ya)(ya)回(hui)系(xi)(xi)(xi)統(tong)(tong)(tong),緩(huan)沖(chong)(chong)罐(guan)(guan)起到(dao)調節系(xi)(xi)(xi)統(tong)(tong)(tong)壓(ya)(ya)(ya)(ya)力(li)(li)(li)波(bo)動的(de)作(zuo)(zuo)用(yong)(yong)(yong)。
三、壓力罐的安裝位置要求
1、農村庭院
在(zai)農村地(di)區,我(wo)們通常用水(shui)(shui)井來使用壓(ya)力罐(guan),考慮到揚程和壓(ya)力的(de)(de)問題,壓(ya)力罐(guan)的(de)(de)位置不應該離井太遠(yuan),但是(shi)由于農村水(shui)(shui)井邊上(shang)(shang)一般(ban)是(shi)露(lu)天(tian)的(de)(de),我(wo)們可以(yi)(yi)考慮把(ba)壓(ya)力罐(guan)裝到離水(shui)(shui)井不遠(yuan)的(de)(de)配房里(li)面,這樣我(wo)們一來可以(yi)(yi)避免風吹雨淋對(dui)壓(ya)力罐(guan)上(shang)(shang)面電(dian)子(zi)器件的(de)(de)損(sun)耗,二來在(zai)房間里(li)也可以(yi)(yi)在(zai)冬天(tian)到來的(de)(de)時候(hou)更好(hao)的(de)(de)去做防(fang)凍(dong)處理。當(dang)然,以(yi)(yi)上(shang)(shang)并不是(shi)說壓(ya)力罐(guan)不能(neng)在(zai)露(lu)天(tian)使用,只是(shi)如(ru)果(guo)有條(tiao)件的(de)(de)話,肯定屋(wu)里(li)更合適一點(dian),如(ru)果(guo)需要露(lu)天(tian)擺(bai)放的(de)(de)話,我(wo)們可以(yi)(yi)用大飲料瓶(ping)將(jiang)壓(ya)力開關保(bao)護一下,至(zhi)于罐(guan)體,只要選擇304不銹鋼(gang)材質,是(shi)完全沒(mei)有腐(fu)蝕或者上(shang)(shang)銹擔(dan)憂的(de)(de)。
2、城市使用
由于水(shui)壓不(bu)足,許多(duo)城市(shi)家(jia)庭(ting)將購買壓力(li)罐的(de)(de)(de)問題被用(yong)(yong)(yong)作(zuo)壓上水(shui)使(shi)用(yong)(yong)(yong),那么在這個城市(shi),放哪里比較(jiao)合適呢?壓力(li)罐本身(shen)的(de)(de)(de)體積較(jiao)小不(bu)會占用(yong)(yong)(yong)太多(duo)的(de)(de)(de)空間(jian)(jian),不(bu)過容量還是(shi)蠻大的(de)(de)(de),就像家(jia)用(yong)(yong)(yong)冰箱一樣,所(suo)以我們(men)可(ke)以安(an)(an)裝在浴室或廚(chu)房角落(luo)的(de)(de)(de)一個角落(luo)里,因為它既不(bu)占用(yong)(yong)(yong)太多(duo)空間(jian)(jian),也不(bu)會影響(xiang)家(jia)庭(ting)本身(shen)的(de)(de)(de)裝飾精美(mei)程(cheng)度,如果(guo)有單獨(du)的(de)(de)(de)儲物間(jian)(jian)的(de)(de)(de)話也是(shi)不(bu)錯的(de)(de)(de)安(an)(an)裝位置(zhi)。
總(zong)之,對壓(ya)力罐(guan)的(de)(de)(de)(de)安(an)(an)裝(zhuang)(zhuang)位置(zhi)(zhi)沒(mei)有嚴格的(de)(de)(de)(de)要求。在(zai)安(an)(an)裝(zhuang)(zhuang)時,我(wo)(wo)們(men)還需(xu)(xu)要考慮(lv)其他一(yi)些問題(ti),如(ru)水(shui)源的(de)(de)(de)(de)位置(zhi)(zhi)、水(shui)泵的(de)(de)(de)(de)揚程和(he)水(shui)的(de)(de)(de)(de)位置(zhi)(zhi)。根據以(yi)(yi)上(shang)問題(ti),我(wo)(wo)們(men)可以(yi)(yi)計(ji)算出一(yi)個合理(li)的(de)(de)(de)(de)位置(zhi)(zhi)。此外,我(wo)(wo)們(men)還需(xu)(xu)要考慮(lv)天(tian)氣等原因,如(ru)冬季寒冷(leng),為了方便保溫,我(wo)(wo)們(men)需(xu)(xu)要盡量把(ba)它(ta)安(an)(an)裝(zhuang)(zhuang)在(zai)室(shi)內,一(yi)些人甚至為了防(fang)止冰凍而把(ba)它(ta)安(an)(an)裝(zhuang)(zhuang)在(zai)地下。如(ru)果(guo)購買的(de)(de)(de)(de)壓(ya)力罐(guan)壓(ya)力較小,但它(ta)們(men)使(shi)用(yong)的(de)(de)(de)(de)出水(shui)口較多,這時,我(wo)(wo)們(men)可以(yi)(yi)將(jiang)安(an)(an)裝(zhuang)(zhuang)位置(zhi)(zhi)放高,并借助一(yi)下自(zi)然壓(ya)力。
四、家用壓力罐怎么安裝
1、放置壓力罐
我們先將品牌壓力罐側(ce)放(fang),將(jiang)壓力(li)(li)罐的(de)(de)支(zhi)架找到,用螺(luo)絲將(jiang)支(zhi)架固定(ding)在壓力(li)(li)罐底部,再將(jiang)壓力(li)(li)罐放(fang)在水(shui)(shui)源附近的(de)(de)位置,比如所我們將(jiang)壓力(li)(li)罐放(fang)在水(shui)(shui)井旁(pang)邊(bian)。壓力(li)(li)罐要(yao)水(shui)(shui)平放(fang)置,不(bu)能(neng)出(chu)現傾斜的(de)(de)問題。我們在安(an)裝壓力(li)(li)罐時,要(yao)先準(zhun)備好(hao)相關的(de)(de)材料和(he)工(gong)具,例如我們要(yao)根據壓力(li)(li)罐的(de)(de)大小準(zhun)備好(hao)相應規格的(de)(de)水(shui)(shui)管,大家還需準(zhun)備好(hao)止回(hui)閥、生(sheng)料帶、水(shui)(shui)管接頭(tou)、水(shui)(shui)泵、熱(re)熔(rong)機、剪刀、扳手等安(an)裝材料和(he)工(gong)作。
2、安裝配件
大家要先安(an)裝(zhuang)(zhuang)壓力(li)(li)罐排(pai)污口處(chu)的波紋(wen)(wen)管,在(zai)(zai)安(an)裝(zhuang)(zhuang)時(shi)將(jiang)波紋(wen)(wen)管一(yi)端(duan)放膠墊,并將(jiang)它接(jie)(jie)在(zai)(zai)排(pai)污口上(shang),波紋(wen)(wen)管的另一(yi)端(duan)安(an)裝(zhuang)(zhuang)水龍頭。接(jie)(jie)著我們(men)安(an)裝(zhuang)(zhuang)壓力(li)(li)開關和(he)壓力(li)(li)表(biao)。大家用扳(ban)手將(jiang)三通(tong)接(jie)(jie)在(zai)(zai)壓力(li)(li)表(biao)接(jie)(jie)口上(shang),再(zai)把壓力(li)(li)表(biao)、壓力(li)(li)開關接(jie)(jie)在(zai)(zai)三通(tong)上(shang)。在(zai)(zai)安(an)裝(zhuang)(zhuang)時(shi)接(jie)(jie)口處(chu)可纏繞生料帶加強密封。最后我們(men)安(an)裝(zhuang)(zhuang)安(an)全閥(fa)和(he)負(fu)壓閥(fa),我們(men)用扳(ban)手將(jiang)安(an)全閥(fa)和(he)負(fu)壓閥(fa)接(jie)(jie)在(zai)(zai)壓力(li)(li)罐相(xiang)應的接(jie)(jie)口處(chu),在(zai)(zai)安(an)裝(zhuang)(zhuang)時(shi)不能用力(li)(li)過猛(meng),以免閥(fa)門損(sun)壞。
3、安裝水管
我(wo)們在(zai)壓力(li)罐出水口(kou)處纏繞生(sheng)料帶,再將(jiang)(jiang)內絲(si)活接(jie)頭接(jie)在(zai)出水口(kou)上,接(jie)著我(wo)們通過熱熔焊接(jie)的方(fang)式(shi)將(jiang)(jiang)水管(guan)和接(jie)頭焊接(jie)好,再水閥裝(zhuang)在(zai)水管(guan)上。水閥安裝(zhuang)好之后,我(wo)們通過熱熔連(lian)接(jie)的方(fang)式(shi)將(jiang)(jiang)管(guan)道和家中用水主管(guan)接(jie)在(zai)一(yi)起。
我們(men)安(an)(an)裝(zhuang)水(shui)(shui)(shui)(shui)泵和(he)進(jin)水(shui)(shui)(shui)(shui)口(kou)管(guan)道。我們(men)用(yong)尺子(zi)測量好水(shui)(shui)(shui)(shui)泵口(kou)到(dao)壓力罐出(chu)水(shui)(shui)(shui)(shui)口(kou)的長度,用(yong)剪刀將水(shui)(shui)(shui)(shui)管(guan)剪切(qie)好。接(jie)(jie)(jie)(jie)著在接(jie)(jie)(jie)(jie)頭(tou)兩端纏繞生料帶并將接(jie)(jie)(jie)(jie)頭(tou)接(jie)(jie)(jie)(jie)在水(shui)(shui)(shui)(shui)泵口(kou)處(chu),再(zai)將止(zhi)回閥(fa)接(jie)(jie)(jie)(jie)在接(jie)(jie)(jie)(jie)頭(tou)上,止(zhi)回閥(fa)另(ling)一端接(jie)(jie)(jie)(jie)轉換接(jie)(jie)(jie)(jie)頭(tou)。下一步我們(men)通過(guo)水(shui)(shui)(shui)(shui)管(guan)將進(jin)水(shui)(shui)(shui)(shui)口(kou)和(he)水(shui)(shui)(shui)(shui)泵口(kou)接(jie)(jie)(jie)(jie)在一起。最后我們(men)將水(shui)(shui)(shui)(shui)泵另(ling)一個接(jie)(jie)(jie)(jie)口(kou)處(chu)連接(jie)(jie)(jie)(jie)水(shui)(shui)(shui)(shui)管(guan),水(shui)(shui)(shui)(shui)管(guan)要延長到(dao)水(shui)(shui)(shui)(shui)源(yuan)處(chu),在安(an)(an)裝(zhuang)水(shui)(shui)(shui)(shui)管(guan)時水(shui)(shui)(shui)(shui)管(guan)中間可安(an)(an)裝(zhuang)水(shui)(shui)(shui)(shui)閥(fa)開(kai)關。
4、安裝電源電線
我們用(yong)螺(luo)絲刀將(jiang)壓(ya)力(li)開關保護(hu)蓋(gai)的(de)螺(luo)絲擰(ning)松,把保護(hu)蓋(gai)取下。接(jie)著我們準備好帶(dai)插頭的(de)電(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)線(xian)(xian),將(jiang)電(dian)(dian)(dian)(dian)線(xian)(xian)從進線(xian)(xian)口(kou)穿入(ru)(ru)并接(jie)在壓(ya)力(li)開關相應的(de)接(jie)線(xian)(xian)端(duan)口(kou)上。大家(jia)再(zai)準備一根帶(dai)插座(zuo)的(de)電(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)線(xian)(xian),將(jiang)電(dian)(dian)(dian)(dian)線(xian)(xian)從壓(ya)力(li)開關另(ling)一側進線(xian)(xian)口(kou)穿入(ru)(ru),將(jiang)電(dian)(dian)(dian)(dian)線(xian)(xian)接(jie)在相應的(de)接(jie)線(xian)(xian)端(duan)口(kou)。電(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)線(xian)(xian)接(jie)好之后,我們在壓(ya)力(li)開關上做用(yong)塑料瓶(ping)等做一個保護(hu)罩。
