一、什么是增壓泵
增壓泵就是(shi)用(yong)來起(qi)到(dao)增(zeng)(zeng)壓(ya)作用(yong)的(de)(de)一款水(shui)(shui)泵(beng)(beng)(beng)(beng)，泛指(zhi)能(neng)對管路的(de)(de)液體(ti)進行提供額(e)外壓(ya)力的(de)(de)泵(beng)(beng)(beng)(beng)的(de)(de)統稱(cheng)，其用(yong)途主要有熱水(shui)(shui)器增(zeng)(zeng)壓(ya)用(yong)、高樓低水(shui)(shui)壓(ya)、桑拿浴(yu)、洗浴(yu)等(deng)加壓(ya)用(yong)、公(gong)寓最上層水(shui)(shui)壓(ya)不(bu)足的(de)(de)加壓(ya)、太陽能(neng)自動(dong)增(zeng)(zeng)壓(ya)、反滲透凈水(shui)(shui)器增(zeng)(zeng)壓(ya)用(yong)等(deng)等(deng)。增(zeng)(zeng)壓(ya)泵(beng)(beng)(beng)(beng)并(bing)不(bu)指(zhi)某一種類(lei)型的(de)(de)泵(beng)(beng)(beng)(beng)，只要是(shi)泵(beng)(beng)(beng)(beng)都具(ju)有增(zeng)(zeng)壓(ya)功能(neng)，所以增(zeng)(zeng)壓(ya)泵(beng)(beng)(beng)(beng)包(bao)含的(de)(de)泵(beng)(beng)(beng)(beng)類(lei)產品(pin)繁多，可(ke)以是(shi)管道泵(beng)(beng)(beng)(beng)、離心泵(beng)(beng)(beng)(beng)、污水(shui)(shui)泵(beng)(beng)(beng)(beng)、自吸泵(beng)(beng)(beng)(beng)、多級泵(beng)(beng)(beng)(beng)等(deng)類(lei)型泵(beng)(beng)(beng)(beng)。
增(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)泵(beng)(beng)(beng)在很多家(jia)庭中都非常受(shou)用(yong)(yong)(yong)(yong)，尤其(qi)是(shi)一些高樓層的(de)(de)(de)用(yong)(yong)(yong)(yong)戶幾乎都要用(yong)(yong)(yong)(yong)到增(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)泵(beng)(beng)(beng)。常規(gui)所指(zhi)的(de)(de)(de)增(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)泵(beng)(beng)(beng)分(fen)為：個人家(jia)庭安(an)裝使用(yong)(yong)(yong)(yong)的(de)(de)(de)家(jia)用(yong)(yong)(yong)(yong)增(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)泵(beng)(beng)(beng)和自來(lai)水(shui)公司供(gong)水(shui)或者(zhe)小區第二(er)(er)次供(gong)水(shui)安(an)裝使用(yong)(yong)(yong)(yong)的(de)(de)(de)管道增(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)泵(beng)(beng)(beng)，也可以是(shi)工廠用(yong)(yong)(yong)(yong)水(shui)第二(er)(er)次增(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)使用(yong)(yong)(yong)(yong)的(de)(de)(de)增(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)泵(beng)(beng)(beng)。增(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)泵(beng)(beng)(beng)的(de)(de)(de)意思就(jiu)是(shi)在原來(lai)管道里面水(shui)壓(ya)(ya)(ya)(ya)(ya)的(de)(de)(de)基礎(chu)上進行第二(er)(er)次增(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)的(de)(de)(de)作用(yong)(yong)(yong)(yong)泵(beng)(beng)(beng)進口的(de)(de)(de)壓(ya)(ya)(ya)(ya)(ya)力加上增(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)泵(beng)(beng)(beng)所提(ti)供(gong)的(de)(de)(de)壓(ya)(ya)(ya)(ya)(ya)力就(jiu)是(shi)整個泵(beng)(beng)(beng)出口壓(ya)(ya)(ya)(ya)(ya)力。增(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)泵(beng)(beng)(beng)可以分(fen)為立式(shi)安(an)裝或者(zhe)臥式(shi)安(an)裝，最常用(yong)(yong)(yong)(yong)的(de)(de)(de)家(jia)用(yong)(yong)(yong)(yong)增(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)泵(beng)(beng)(beng)就(jiu)是(shi)：WG型(xing)小型(xing)家(jia)用(yong)(yong)(yong)(yong)增(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)泵(beng)(beng)(beng)，最常用(yong)(yong)(yong)(yong)的(de)(de)(de)第二(er)(er)次供(gong)水(shui)增(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)泵(beng)(beng)(beng)就(jiu)是(shi)：ISG管道增(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)泵(beng)(beng)(beng)、ISW臥式(shi)管道離心(xin)泵(beng)(beng)(beng)或者(zhe)目前新出來(lai)的(de)(de)(de)DL立式(shi)不銹鋼輕型(xing)多級泵(beng)(beng)(beng)。如果(guo)要讓(rang)非自吸式(shi)的(de)(de)(de)增(zeng)(zeng)(zeng)(zeng)壓(ya)(ya)(ya)(ya)(ya)泵(beng)(beng)(beng)達(da)到自吸效果(guo)（泵(beng)(beng)(beng)位(wei)于水(shui)池(chi)上方），可以在泵(beng)(beng)(beng)的(de)(de)(de)吸入口加裝底閥即可。
二、什么是自吸泵
自(zi)(zi)(zi)(zi)吸泵(beng)(beng)(beng)屬(shu)自(zi)(zi)(zi)(zi)吸式離心泵(beng)(beng)(beng)，就是(shi)把(ba)泵(beng)(beng)(beng)安裝在(zai)比(bi)液位(wei)高的地(di)方、第一次把(ba)泵(beng)(beng)(beng)體里面灌(guan)水(shui)之后(hou)啟(qi)動自(zi)(zi)(zi)(zi)吸泵(beng)(beng)(beng)能(neng)(neng)把(ba)水(shui)抽上來(lai)排走的泵(beng)(beng)(beng)，我(wo)們就把(ba)它(ta)統稱為自(zi)(zi)(zi)(zi)吸泵(beng)(beng)(beng)，以后(hou)再使用(yong)就無需(xu)(xu)再次灌(guan)水(shui)即可(ke)(ke)啟(qi)動運行(xing)，自(zi)(zi)(zi)(zi)吸泵(beng)(beng)(beng)是(shi)否(fou)自(zi)(zi)(zi)(zi)吸要看停機后(hou)葉(xie)輪(lun)是(shi)否(fou)浸入水(shui)中(zhong)，自(zi)(zi)(zi)(zi)吸泵(beng)(beng)(beng)就是(shi)因(yin)為有(you)獨特的泵(beng)(beng)(beng)腔結構而可(ke)(ke)以保證每次停機后(hou)葉(xie)輪(lun)都可(ke)(ke)以浸入水(shui)中(zhong)才(cai)保證了其自(zi)(zi)(zi)(zi)吸。自(zi)(zi)(zi)(zi)吸泵(beng)(beng)(beng)不但具有(you)自(zi)(zi)(zi)(zi)吸泵(beng)(beng)(beng)的功(gong)(gong)能(neng)(neng)并且還具有(you)增(zeng)壓泵(beng)(beng)(beng)的功(gong)(gong)能(neng)(neng)，所以我(wo)們也(ye)可(ke)(ke)以把(ba)自(zi)(zi)(zi)(zi)吸泵(beng)(beng)(beng)稱為自(zi)(zi)(zi)(zi)吸增(zeng)壓泵(beng)(beng)(beng)。它(ta)具有(you)結構緊(jin)湊、操作方便(bian)、運行(xing)平穩(wen)、維護容易(yi)、效(xiao)率高、壽命(ming)長，并有(you)較(jiao)強(qiang)的自(zi)(zi)(zi)(zi)吸能(neng)(neng)力等優點。管路不需(xu)(xu)安裝底閥(fa)，工作前(qian)只需(xu)(xu)保證泵(beng)(beng)(beng)體內儲有(you)定量引液即可(ke)(ke)。不同(tong)液體可(ke)(ke)采用(yong)不同(tong)材質自(zi)(zi)(zi)(zi)吸泵(beng)(beng)(beng)。
三、增壓泵和自吸泵的區別
1、從安裝位置來看
增壓泵一般(ban)安(an)裝在進水(shui)管(guan)(guan)道(dao)上(shang)，在原有(you)管(guan)(guan)道(dao)上(shang)剪(jian)(jian)斷(duan)一段(duan)后泵串聯到(dao)管(guan)(guan)路上(shang)即可，管(guan)(guan)道(dao)中間(jian)的水(shui)位高于泵體(ti)；自吸泵需(xu)安(an)裝在回水(shui)管(guan)(guan)上(shang)，增壓系統壓力，以(yi)助其循環，用剪(jian)(jian)子(zi)剪(jian)(jian)斷(duan)一段(duan)管(guan)(guan)道(dao)，泵串聯到(dao)管(guan)(guan)路上(shang)即可，管(guan)(guan)道(dao)中間(jian)的水(shui)位低于泵體(ti)。
2、從適用范圍來看
增壓(ya)泵(beng)一般用(yong)在集中(zhong)供暖系統(tong)上，以及(ji)(ji)太陽能落(luo)差(cha)小導致水壓(ya)小，以及(ji)(ji)熱水器(qi)水壓(ya)小，需(xu)要增壓(ya)的情況下；自吸泵(beng)主(zhu)要針對的是(shi)自采暖用(yong)戶，或者中(zhong)大(da)戶型家庭取暖系統(tong)循環(huan)、地暖熱水循環(huan)使用(yong)。如果(guo)進水溫度(du)(du)可以、出水溫度(du)(du)較低(di)(di)，安(an)裝自吸泵(beng)就可以解決(jue)問題，但是(shi)如果(guo)進回水溫度(du)(du)都(dou)低(di)(di)，那么需(xu)要先(xian)查找不熱的原因(yin)。
3、從增壓強弱來看
增(zeng)(zeng)壓(ya)泵(beng)(beng)主要(yao)解決水壓(ya)偏(pian)小的(de)問題(ti)，屬(shu)于壓(ya)力偏(pian)小的(de)類型泵(beng)(beng)，這主要(yao)是由水泵(beng)(beng)結構決定的(de)，增(zeng)(zeng)壓(ya)泵(beng)(beng)是靠(kao)離心力增(zeng)(zeng)壓(ya)；而自(zi)吸泵(beng)(beng)相(xiang)較增(zeng)(zeng)壓(ya)泵(beng)(beng)壓(ya)力較大，可以帶動整個供暖系統的(de)循(xun)環。
4、從產品操作來看
增壓泵多是自(zi)(zi)動(dong)控(kong)制(zhi)，即開關是水流自(zi)(zi)動(dong)開關控(kong)制(zhi)，只要(yao)有(you)水流動(dong)開關自(zi)(zi)動(dong)啟動(dong)，沒有(you)水流動(dong)自(zi)(zi)動(dong)關閉；自(zi)(zi)吸泵大多是手(shou)動(dong)控(kong)制(zhi)，需(xu)要(yao)人為(wei)開動(dong)開關，實(shi)現水泵接通運(yun)轉和停止(zhi)運(yun)轉。
四、自吸泵和增壓泵哪個效果好
自吸(xi)泵(beng)和增(zeng)壓(ya)泵(beng)都(dou)可以(yi)對自來水進行(xing)增(zeng)壓(ya)，增(zeng)壓(ya)泵(beng)帶有(you)(you)恒(heng)(heng)壓(ya)裝(zhuang)置(zhi)(zhi)，它能夠(gou)讓水管內(nei)的水壓(ya)保持一個相(xiang)對平均的壓(ya)力。但自吸(xi)泵(beng)是不(bu)帶恒(heng)(heng)壓(ya)裝(zhuang)置(zhi)(zhi)的，當在本來就(jiu)有(you)(you)水壓(ya)的管道上(shang)裝(zhuang)它后，嚴(yan)重情況下(xia)會(hui)把水表玻璃都(dou)會(hui)吸(xi)碎掉。
如(ru)果水(shui)(shui)沒有斷流情況可(ke)以使(shi)用(yong)增壓(ya)泵，如(ru)果經常斷流就要準備個容器（水(shui)(shui)池(chi)、水(shui)(shui)罐等），容器上(shang)可(ke)以裝排水(shui)(shui)管(guan)還(huan)可(ke)以使(shi)用(yong)增壓(ya)泵，不能裝排水(shui)(shui)管(guan)就只能裝自吸泵。
適合選增壓泵的情況：
使(shi)用自(zi)(zi)來水的住戶：因為(wei)自(zi)(zi)來水是具(ju)有壓(ya)力的，尤(you)其(qi)是住在高層的住戶，需要(yao)借助增壓(ya)泵來增壓(ya)，讓(rang)壓(ya)力達(da)到0.65MPa左右，才能實(shi)現(xian)正常使(shi)用。
適合選自吸泵的情況：
像(xiang)很多(duo)農村家里(li)(li)，還沒有通自來水(shui)的，只能(neng)(neng)使用井水(shui)，水(shui)井或水(shui)缸的位置比較低，那么使用自吸(xi)泵(beng)的話，能(neng)(neng)夠將水(shui)自動吸(xi)進凈水(shui)器里(li)(li)面。
另外，在(zai)購買自吸(xi)泵和增(zeng)壓泵時，也要注意(yi)以(yi)下一些事項：
購買增壓泵時，要向廠家(jia)提供(gong)(gong)自(zi)家(jia)的(de)供(gong)(gong)水管道的(de)型(xing)號、口徑以及(ji)自(zi)己所需要的(de)流量大小和揚程，這樣(yang)廠家(jia)就能根據用戶(hu)的(de)要求(qiu)，給出一(yi)款合(he)適(shi)的(de)泵。
購買自吸泵時(shi)，基本(ben)也(ye)和增壓泵的購買注(zhu)意事項差不(bu)多，當然(ran)用(yong)戶也(ye)可以向廠家說(shuo)明自己(ji)所想抽取(qu)的是什么液體(ti)介(jie)質，這樣廠家就能夠匹(pi)配出適(shi)合用(yong)戶的自吸泵，無論是抽取(qu)清水還(huan)是其他介(jie)質。
