一、緩沖罐的作用
緩(huan)(huan)沖(chong)罐主要用(yong)于各種(zhong)系(xi)(xi)統(tong)中緩(huan)(huan)沖(chong)系(xi)(xi)統(tong)的壓(ya)(ya)(ya)(ya)力(li)波(bo)動,使系(xi)(xi)統(tong)工作(zuo)更平穩(wen)。緩(huan)(huan)沖(chong)罐的緩(huan)(huan)沖(chong)性能主要通過壓(ya)(ya)(ya)(ya)縮(suo)罐內的壓(ya)(ya)(ya)(ya)縮(suo)空氣(qi)來實現。緩(huan)(huan)沖(chong)罐有(you)隔(ge)膜式緩(huan)(huan)沖(chong)罐和氣(qi)囊式兩種(zhong),被廣泛應用(yong)于中央(yang)空調、鍋爐、熱(re)水(shui)(shui)(shui)器、變頻、恒壓(ya)(ya)(ya)(ya)供水(shui)(shui)(shui)設備中,其緩(huan)(huan)沖(chong)系(xi)(xi)統(tong)壓(ya)(ya)(ya)(ya)力(li)波(bo)動,消除(chu)水(shui)(shui)(shui)錘起到穩(wen)壓(ya)(ya)(ya)(ya)卸荷的作(zuo)用(yong),在系(xi)(xi)統(tong)內水(shui)(shui)(shui)壓(ya)(ya)(ya)(ya)輕微變化(hua)時,緩(huan)(huan)沖(chong)罐氣(qi)囊的自動膨脹(zhang)收縮(suo)會對水(shui)(shui)(shui)壓(ya)(ya)(ya)(ya)的變化(hua)有(you)一(yi)定緩(huan)(huan)沖(chong)作(zuo)用(yong),能保(bao)證系(xi)(xi)統(tong)的水(shui)(shui)(shui)壓(ya)(ya)(ya)(ya)穩(wen)定,水(shui)(shui)(shui)泵不會因壓(ya)(ya)(ya)(ya)力(li)的改變而頻繁的開啟。
二、緩沖罐的結構和工作原理
緩沖罐(guan)是(shi)利用(yong)液(ye)體(ti)的(de)壓(ya)縮性極小(xiao)的(de)性質,用(yong)外力(li)(li)(li)將液(ye)體(ti)儲(chu)存在罐(guan)內(nei),氣體(ti)受(shou)到(dao)壓(ya)縮壓(ya)力(li)(li)(li)升高(gao),當外力(li)(li)(li)消(xiao)失壓(ya)縮氣體(ti)膨脹(zhang)可將水排除。
緩沖罐(guan)(guan)主(zhu)要由氣(qi)(qi)(qi)(qi)門蓋、充氣(qi)(qi)(qi)(qi)口、氣(qi)(qi)(qi)(qi)囊(nang)(nang)、碳鋼罐(guan)(guan)體(ti)、法蘭盤(pan)組成,當其(qi)連(lian)接(jie)到(dao)水(shui)系(xi)(xi)(xi)(xi)統(tong)(tong)上時(shi),主(zhu)要起一個蓄能器的(de)(de)作用(yong),當系(xi)(xi)(xi)(xi)統(tong)(tong)水(shui)壓(ya)(ya)(ya)(ya)力(li)(li)(li)大于(yu)(yu)(yu)緩沖罐(guan)(guan)碳鋼罐(guan)(guan)體(ti)于(yu)(yu)(yu)氣(qi)(qi)(qi)(qi)囊(nang)(nang)之間(jian)(jian)的(de)(de)氣(qi)(qi)(qi)(qi)壓(ya)(ya)(ya)(ya)力(li)(li)(li)時(shi),系(xi)(xi)(xi)(xi)統(tong)(tong)水(shui)會在(zai)系(xi)(xi)(xi)(xi)統(tong)(tong)壓(ya)(ya)(ya)(ya)力(li)(li)(li)的(de)(de)作用(yong)下(xia)擠入緩沖罐(guan)(guan)氣(qi)(qi)(qi)(qi)囊(nang)(nang)內(nei),這(zhe)樣一是(shi)(shi)(shi)會壓(ya)(ya)(ya)(ya)縮罐(guan)(guan)體(ti)于(yu)(yu)(yu)氣(qi)(qi)(qi)(qi)囊(nang)(nang)之間(jian)(jian)的(de)(de)氣(qi)(qi)(qi)(qi),使其(qi)體(ti)積(ji)減(jian)(jian)小(xiao)(xiao),壓(ya)(ya)(ya)(ya)力(li)(li)(li)增(zeng)(zeng)大;罐(guan)(guan)體(ti)于(yu)(yu)(yu)氣(qi)(qi)(qi)(qi)囊(nang)(nang)之間(jian)(jian)是(shi)(shi)(shi)出廠時(shi)預充的(de)(de)氣(qi)(qi)(qi)(qi),罐(guan)(guan)體(ti)外面為烤(kao)漆層(ceng),進出水(shui)口直(zhi)(zhi)接(jie)用(yong)三通或(huo)金屬軟管連(lian)接(jie)到(dao)系(xi)(xi)(xi)(xi)統(tong)(tong),排氣(qi)(qi)(qi)(qi)閥接(jie)口可(ke)(ke)及時(shi)排出系(xi)(xi)(xi)(xi)統(tong)(tong)和氣(qi)(qi)(qi)(qi)囊(nang)(nang)內(nei)的(de)(de)水(shui)溢出的(de)(de)空(kong)氣(qi)(qi)(qi)(qi),也可(ke)(ke)用(yong)閘閥直(zhi)(zhi)接(jie)關死,以免水(shui)從(cong)頂部溢出,防塵帽下(xia)面是(shi)(shi)(shi)充/放(fang)氣(qi)(qi)(qi)(qi)口,可(ke)(ke)補(bu)充氣(qi)(qi)(qi)(qi)或(huo)放(fang)掉一部分氣(qi)(qi)(qi)(qi)體(ti)。二是(shi)(shi)(shi)會增(zeng)(zeng)加系(xi)(xi)(xi)(xi)統(tong)(tong)整(zheng)個水(shui)的(de)(de)容納空(kong)間(jian)(jian),使系(xi)(xi)(xi)(xi)統(tong)(tong)壓(ya)(ya)(ya)(ya)力(li)(li)(li)減(jian)(jian)小(xiao)(xiao),直(zhi)(zhi)到(dao)系(xi)(xi)(xi)(xi)統(tong)(tong)水(shui)的(de)(de)壓(ya)(ya)(ya)(ya)力(li)(li)(li)和罐(guan)(guan)體(ti)于(yu)(yu)(yu)氣(qi)(qi)(qi)(qi)囊(nang)(nang)之間(jian)(jian)的(de)(de)氣(qi)(qi)(qi)(qi)壓(ya)(ya)(ya)(ya)力(li)(li)(li)達(da)(da)到(dao)新的(de)(de)平衡才停止進水(shui)。當系(xi)(xi)(xi)(xi)統(tong)(tong)水(shui)壓(ya)(ya)(ya)(ya)力(li)(li)(li)小(xiao)(xiao)于(yu)(yu)(yu)膨(peng)脹(zhang)罐(guan)(guan)內(nei)氣(qi)(qi)(qi)(qi)體(ti)壓(ya)(ya)(ya)(ya)力(li)(li)(li)時(shi),氣(qi)(qi)(qi)(qi)囊(nang)(nang)內(nei)的(de)(de)水(shui)會在(zai)罐(guan)(guan)體(ti)于(yu)(yu)(yu)氣(qi)(qi)(qi)(qi)囊(nang)(nang)之間(jian)(jian)的(de)(de)氮(dan)氣(qi)(qi)(qi)(qi)的(de)(de)壓(ya)(ya)(ya)(ya)力(li)(li)(li)作用(yong)下(xia)擠出,補(bu)回到(dao)系(xi)(xi)(xi)(xi)統(tong)(tong),系(xi)(xi)(xi)(xi)統(tong)(tong)水(shui)容積(ji)減(jian)(jian)小(xiao)(xiao)壓(ya)(ya)(ya)(ya)力(li)(li)(li)上升,罐(guan)(guan)體(ti)于(yu)(yu)(yu)氣(qi)(qi)(qi)(qi)囊(nang)(nang)之間(jian)(jian)的(de)(de)氣(qi)(qi)(qi)(qi)體(ti)積(ji)增(zeng)(zeng)大壓(ya)(ya)(ya)(ya)力(li)(li)(li)下(xia)降(jiang),直(zhi)(zhi)到(dao)兩(liang)者達(da)(da)到(dao)新的(de)(de)平衡,水(shui)停止從(cong)氣(qi)(qi)(qi)(qi)囊(nang)(nang)擠壓(ya)(ya)(ya)(ya)回系(xi)(xi)(xi)(xi)統(tong)(tong),緩沖罐(guan)(guan)起到(dao)調(diao)節系(xi)(xi)(xi)(xi)統(tong)(tong)壓(ya)(ya)(ya)(ya)力(li)(li)(li)波動的(de)(de)作用(yong)。
三、壓力罐的安裝位置要求
1、農村庭院
在(zai)農村地區,我(wo)(wo)們(men)通(tong)常用(yong)(yong)(yong)水井(jing)來使(shi)(shi)用(yong)(yong)(yong)壓力罐(guan),考(kao)慮(lv)到揚程和(he)壓力的(de)問(wen)題(ti),壓力罐(guan)的(de)位置(zhi)不應該離(li)(li)井(jing)太遠(yuan),但(dan)是由于農村水井(jing)邊上(shang)一(yi)般是露(lu)(lu)天(tian)的(de),我(wo)(wo)們(men)可(ke)以考(kao)慮(lv)把壓力罐(guan)裝到離(li)(li)水井(jing)不遠(yuan)的(de)配(pei)房里面,這樣我(wo)(wo)們(men)一(yi)來可(ke)以避(bi)免(mian)風吹雨淋對壓力罐(guan)上(shang)面電子器件(jian)的(de)損耗,二(er)來在(zai)房間里也可(ke)以在(zai)冬天(tian)到來的(de)時候更好的(de)去做防凍處理。當(dang)然,以上(shang)并不是說壓力罐(guan)不能在(zai)露(lu)(lu)天(tian)使(shi)(shi)用(yong)(yong)(yong),只(zhi)是如果(guo)有(you)條件(jian)的(de)話(hua),肯定屋里更合(he)適一(yi)點,如果(guo)需要(yao)露(lu)(lu)天(tian)擺放的(de)話(hua),我(wo)(wo)們(men)可(ke)以用(yong)(yong)(yong)大飲料(liao)瓶(ping)將壓力開關保護(hu)一(yi)下(xia),至于罐(guan)體,只(zhi)要(yao)選擇(ze)304不銹鋼材質,是完(wan)全沒有(you)腐蝕或者上(shang)銹擔憂的(de)。
2、城市使用
由(you)于水壓(ya)不(bu)足,許多(duo)(duo)城(cheng)市家(jia)庭(ting)將(jiang)購買壓(ya)力(li)罐的(de)(de)(de)(de)問題被用作壓(ya)上(shang)水使用,那么在這個城(cheng)市,放哪里(li)比較合適呢?壓(ya)力(li)罐本身的(de)(de)(de)(de)體積較小不(bu)會占用太多(duo)(duo)的(de)(de)(de)(de)空間,不(bu)過容量(liang)還是(shi)蠻大的(de)(de)(de)(de),就像(xiang)家(jia)用冰箱(xiang)一(yi)樣,所以我們(men)可以安裝在浴室或廚房(fang)角(jiao)落的(de)(de)(de)(de)一(yi)個角(jiao)落里(li),因為它既不(bu)占用太多(duo)(duo)空間,也不(bu)會影響家(jia)庭(ting)本身的(de)(de)(de)(de)裝飾精美程度(du),如果有單獨的(de)(de)(de)(de)儲(chu)物間的(de)(de)(de)(de)話也是(shi)不(bu)錯的(de)(de)(de)(de)安裝位(wei)置。
總之,對壓力(li)(li)罐(guan)的(de)安裝位(wei)置(zhi)沒有(you)嚴格的(de)要求。在(zai)安裝時(shi),我們(men)還需(xu)要考(kao)慮(lv)其他(ta)一(yi)些問題(ti),如水源的(de)位(wei)置(zhi)、水泵的(de)揚程和水的(de)位(wei)置(zhi)。根據以上(shang)問題(ti),我們(men)可以計算出一(yi)個(ge)合理的(de)位(wei)置(zhi)。此外,我們(men)還需(xu)要考(kao)慮(lv)天(tian)氣等原(yuan)因(yin),如冬季寒冷,為了方便保(bao)溫,我們(men)需(xu)要盡(jin)量(liang)把它(ta)安裝在(zai)室(shi)內,一(yi)些人(ren)甚(shen)至為了防止冰凍(dong)而把它(ta)安裝在(zai)地下。如果購買的(de)壓力(li)(li)罐(guan)壓力(li)(li)較小,但(dan)它(ta)們(men)使(shi)用的(de)出水口較多,這時(shi),我們(men)可以將(jiang)安裝位(wei)置(zhi)放高(gao),并借助一(yi)下自(zi)然壓力(li)(li)。
四、家用壓力罐怎么安裝
