一、緩沖罐的作用
緩沖(chong)(chong)罐主要用于各種系(xi)(xi)(xi)統(tong)中(zhong)緩沖(chong)(chong)系(xi)(xi)(xi)統(tong)的(de)(de)壓(ya)(ya)(ya)(ya)力波動(dong)(dong),使系(xi)(xi)(xi)統(tong)工(gong)作(zuo)更平穩。緩沖(chong)(chong)罐的(de)(de)緩沖(chong)(chong)性(xing)能(neng)主要通過壓(ya)(ya)(ya)(ya)縮罐內的(de)(de)壓(ya)(ya)(ya)(ya)縮空(kong)氣來實現(xian)。緩沖(chong)(chong)罐有隔(ge)膜式緩沖(chong)(chong)罐和氣囊(nang)式兩種,被(bei)廣泛應用于中(zhong)央空(kong)調、鍋爐、熱水(shui)器、變(bian)頻、恒壓(ya)(ya)(ya)(ya)供水(shui)設(she)備中(zhong),其緩沖(chong)(chong)系(xi)(xi)(xi)統(tong)壓(ya)(ya)(ya)(ya)力波動(dong)(dong),消除水(shui)錘起到穩壓(ya)(ya)(ya)(ya)卸荷的(de)(de)作(zuo)用,在系(xi)(xi)(xi)統(tong)內水(shui)壓(ya)(ya)(ya)(ya)輕微變(bian)化(hua)時,緩沖(chong)(chong)罐氣囊(nang)的(de)(de)自動(dong)(dong)膨脹收縮會對水(shui)壓(ya)(ya)(ya)(ya)的(de)(de)變(bian)化(hua)有一定緩沖(chong)(chong)作(zuo)用,能(neng)保證系(xi)(xi)(xi)統(tong)的(de)(de)水(shui)壓(ya)(ya)(ya)(ya)穩定,水(shui)泵不會因壓(ya)(ya)(ya)(ya)力的(de)(de)改變(bian)而(er)頻繁的(de)(de)開啟。
二、緩沖罐的結構和工作原理
緩沖罐(guan)是利用(yong)液體(ti)(ti)的壓(ya)縮(suo)性(xing)極小的性(xing)質,用(yong)外(wai)力(li)將(jiang)液體(ti)(ti)儲(chu)存在(zai)罐(guan)內,氣體(ti)(ti)受到壓(ya)縮(suo)壓(ya)力(li)升高,當外(wai)力(li)消失壓(ya)縮(suo)氣體(ti)(ti)膨(peng)脹可將(jiang)水排除(chu)。
緩(huan)(huan)沖(chong)罐(guan)(guan)(guan)(guan)主(zhu)要(yao)由(you)氣(qi)(qi)(qi)門蓋(gai)、充(chong)(chong)氣(qi)(qi)(qi)口(kou)、氣(qi)(qi)(qi)囊、碳鋼(gang)罐(guan)(guan)(guan)(guan)體(ti)(ti)(ti)(ti)(ti)、法(fa)蘭(lan)盤(pan)組成,當(dang)其(qi)連(lian)接(jie)(jie)到(dao)(dao)水(shui)系(xi)(xi)統(tong)(tong)(tong)上(shang)時(shi)(shi),主(zhu)要(yao)起(qi)(qi)一個蓄能器的(de)(de)(de)作用(yong),當(dang)系(xi)(xi)統(tong)(tong)(tong)水(shui)壓(ya)(ya)(ya)(ya)力(li)(li)(li)(li)大于(yu)緩(huan)(huan)沖(chong)罐(guan)(guan)(guan)(guan)碳鋼(gang)罐(guan)(guan)(guan)(guan)體(ti)(ti)(ti)(ti)(ti)于(yu)氣(qi)(qi)(qi)囊之(zhi)間的(de)(de)(de)氣(qi)(qi)(qi)壓(ya)(ya)(ya)(ya)力(li)(li)(li)(li)時(shi)(shi),系(xi)(xi)統(tong)(tong)(tong)水(shui)會在系(xi)(xi)統(tong)(tong)(tong)壓(ya)(ya)(ya)(ya)力(li)(li)(li)(li)的(de)(de)(de)作用(yong)下(xia)擠入緩(huan)(huan)沖(chong)罐(guan)(guan)(guan)(guan)氣(qi)(qi)(qi)囊內,這樣一是(shi)會壓(ya)(ya)(ya)(ya)縮罐(guan)(guan)(guan)(guan)體(ti)(ti)(ti)(ti)(ti)于(yu)氣(qi)(qi)(qi)囊之(zhi)間的(de)(de)(de)氣(qi)(qi)(qi),使其(qi)體(ti)(ti)(ti)(ti)(ti)積(ji)減小(xiao)(xiao),壓(ya)(ya)(ya)(ya)力(li)(li)(li)(li)增(zeng)大;罐(guan)(guan)(guan)(guan)體(ti)(ti)(ti)(ti)(ti)于(yu)氣(qi)(qi)(qi)囊之(zhi)間是(shi)出(chu)(chu)(chu)(chu)廠時(shi)(shi)預充(chong)(chong)的(de)(de)(de)氣(qi)(qi)(qi),罐(guan)(guan)(guan)(guan)體(ti)(ti)(ti)(ti)(ti)外(wai)面為烤漆層,進出(chu)(chu)(chu)(chu)水(shui)口(kou)直(zhi)(zhi)接(jie)(jie)用(yong)三通或金(jin)屬軟管連(lian)接(jie)(jie)到(dao)(dao)系(xi)(xi)統(tong)(tong)(tong),排氣(qi)(qi)(qi)閥(fa)接(jie)(jie)口(kou)可及時(shi)(shi)排出(chu)(chu)(chu)(chu)系(xi)(xi)統(tong)(tong)(tong)和氣(qi)(qi)(qi)囊內的(de)(de)(de)水(shui)溢出(chu)(chu)(chu)(chu)的(de)(de)(de)空氣(qi)(qi)(qi),也可用(yong)閘閥(fa)直(zhi)(zhi)接(jie)(jie)關死,以免水(shui)從頂部溢出(chu)(chu)(chu)(chu),防塵(chen)帽(mao)下(xia)面是(shi)充(chong)(chong)/放(fang)氣(qi)(qi)(qi)口(kou),可補(bu)充(chong)(chong)氣(qi)(qi)(qi)或放(fang)掉一部分(fen)氣(qi)(qi)(qi)體(ti)(ti)(ti)(ti)(ti)。二(er)是(shi)會增(zeng)加系(xi)(xi)統(tong)(tong)(tong)整(zheng)個水(shui)的(de)(de)(de)容(rong)納(na)空間,使系(xi)(xi)統(tong)(tong)(tong)壓(ya)(ya)(ya)(ya)力(li)(li)(li)(li)減小(xiao)(xiao),直(zhi)(zhi)到(dao)(dao)系(xi)(xi)統(tong)(tong)(tong)水(shui)的(de)(de)(de)壓(ya)(ya)(ya)(ya)力(li)(li)(li)(li)和罐(guan)(guan)(guan)(guan)體(ti)(ti)(ti)(ti)(ti)于(yu)氣(qi)(qi)(qi)囊之(zhi)間的(de)(de)(de)氣(qi)(qi)(qi)壓(ya)(ya)(ya)(ya)力(li)(li)(li)(li)達到(dao)(dao)新的(de)(de)(de)平衡才(cai)停止進水(shui)。當(dang)系(xi)(xi)統(tong)(tong)(tong)水(shui)壓(ya)(ya)(ya)(ya)力(li)(li)(li)(li)小(xiao)(xiao)于(yu)膨脹罐(guan)(guan)(guan)(guan)內氣(qi)(qi)(qi)體(ti)(ti)(ti)(ti)(ti)壓(ya)(ya)(ya)(ya)力(li)(li)(li)(li)時(shi)(shi),氣(qi)(qi)(qi)囊內的(de)(de)(de)水(shui)會在罐(guan)(guan)(guan)(guan)體(ti)(ti)(ti)(ti)(ti)于(yu)氣(qi)(qi)(qi)囊之(zhi)間的(de)(de)(de)氮氣(qi)(qi)(qi)的(de)(de)(de)壓(ya)(ya)(ya)(ya)力(li)(li)(li)(li)作用(yong)下(xia)擠出(chu)(chu)(chu)(chu),補(bu)回(hui)(hui)到(dao)(dao)系(xi)(xi)統(tong)(tong)(tong),系(xi)(xi)統(tong)(tong)(tong)水(shui)容(rong)積(ji)減小(xiao)(xiao)壓(ya)(ya)(ya)(ya)力(li)(li)(li)(li)上(shang)升,罐(guan)(guan)(guan)(guan)體(ti)(ti)(ti)(ti)(ti)于(yu)氣(qi)(qi)(qi)囊之(zhi)間的(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)(ti)(ti)(ti)積(ji)增(zeng)大壓(ya)(ya)(ya)(ya)力(li)(li)(li)(li)下(xia)降(jiang),直(zhi)(zhi)到(dao)(dao)兩者達到(dao)(dao)新的(de)(de)(de)平衡,水(shui)停止從氣(qi)(qi)(qi)囊擠壓(ya)(ya)(ya)(ya)回(hui)(hui)系(xi)(xi)統(tong)(tong)(tong),緩(huan)(huan)沖(chong)罐(guan)(guan)(guan)(guan)起(qi)(qi)到(dao)(dao)調節系(xi)(xi)統(tong)(tong)(tong)壓(ya)(ya)(ya)(ya)力(li)(li)(li)(li)波動的(de)(de)(de)作用(yong)。
三、壓力罐的安裝位置要求
1、農村庭院
在農(nong)村地區,我(wo)們(men)通常用(yong)水(shui)井(jing)來(lai)使用(yong)壓力罐(guan)(guan),考(kao)慮到(dao)揚程(cheng)和壓力的問題,壓力罐(guan)(guan)的位置不(bu)應該離井(jing)太遠,但(dan)是由(you)于(yu)農(nong)村水(shui)井(jing)邊(bian)上(shang)(shang)一(yi)(yi)般是露(lu)(lu)天(tian)的,我(wo)們(men)可(ke)以(yi)(yi)考(kao)慮把壓力罐(guan)(guan)裝到(dao)離水(shui)井(jing)不(bu)遠的配房(fang)里面,這(zhe)樣我(wo)們(men)一(yi)(yi)來(lai)可(ke)以(yi)(yi)避免風吹雨淋對壓力罐(guan)(guan)上(shang)(shang)面電(dian)子(zi)器件(jian)的損耗,二來(lai)在房(fang)間里也可(ke)以(yi)(yi)在冬天(tian)到(dao)來(lai)的時候更(geng)好的去(qu)做(zuo)防(fang)凍處理(li)。當然,以(yi)(yi)上(shang)(shang)并不(bu)是說壓力罐(guan)(guan)不(bu)能在露(lu)(lu)天(tian)使用(yong),只是如果有條件(jian)的話(hua),肯(ken)定屋里更(geng)合適一(yi)(yi)點,如果需要露(lu)(lu)天(tian)擺放的話(hua),我(wo)們(men)可(ke)以(yi)(yi)用(yong)大(da)飲料瓶將(jiang)壓力開關保護(hu)一(yi)(yi)下,至于(yu)罐(guan)(guan)體(ti),只要選擇304不(bu)銹鋼(gang)材質(zhi),是完(wan)全沒(mei)有腐(fu)蝕或者上(shang)(shang)銹擔(dan)憂(you)的。
2、城市使用
由(you)于(yu)水(shui)(shui)壓(ya)(ya)不(bu)足,許多城(cheng)市家(jia)(jia)庭將購買壓(ya)(ya)力(li)(li)罐的(de)問(wen)題(ti)被用作壓(ya)(ya)上水(shui)(shui)使用,那么在這個(ge)城(cheng)市,放(fang)哪里比較(jiao)合(he)適呢?壓(ya)(ya)力(li)(li)罐本身的(de)體積(ji)較(jiao)小不(bu)會占用太多的(de)空(kong)間,不(bu)過容(rong)量還是蠻(man)大(da)的(de),就像家(jia)(jia)用冰箱一樣,所以(yi)我(wo)們可以(yi)安裝在浴室或廚房角落的(de)一個(ge)角落里,因為它既不(bu)占用太多空(kong)間,也(ye)不(bu)會影響家(jia)(jia)庭本身的(de)裝飾(shi)精美程(cheng)度,如(ru)果有單獨的(de)儲物間的(de)話(hua)也(ye)是不(bu)錯的(de)安裝位置。
總之,對(dui)壓力(li)(li)罐的(de)安(an)裝(zhuang)位(wei)置沒有(you)嚴格的(de)要(yao)求。在安(an)裝(zhuang)時,我(wo)(wo)(wo)們(men)還(huan)需(xu)要(yao)考慮(lv)其他一(yi)(yi)(yi)些問題,如水(shui)源的(de)位(wei)置、水(shui)泵的(de)揚(yang)程(cheng)和水(shui)的(de)位(wei)置。根據以上問題,我(wo)(wo)(wo)們(men)可(ke)(ke)以計算出一(yi)(yi)(yi)個合理的(de)位(wei)置。此外(wai),我(wo)(wo)(wo)們(men)還(huan)需(xu)要(yao)考慮(lv)天氣(qi)等(deng)原因,如冬季(ji)寒冷,為(wei)了(le)方便(bian)保(bao)溫(wen),我(wo)(wo)(wo)們(men)需(xu)要(yao)盡量把(ba)它安(an)裝(zhuang)在室內,一(yi)(yi)(yi)些人甚至(zhi)為(wei)了(le)防止(zhi)冰凍而把(ba)它安(an)裝(zhuang)在地(di)下。如果購買的(de)壓力(li)(li)罐壓力(li)(li)較(jiao)小,但(dan)它們(men)使用的(de)出水(shui)口較(jiao)多,這時,我(wo)(wo)(wo)們(men)可(ke)(ke)以將安(an)裝(zhuang)位(wei)置放高,并借助一(yi)(yi)(yi)下自然壓力(li)(li)。
