一、什么是增壓泵
增壓泵就(jiu)是用來(lai)起到增(zeng)壓(ya)(ya)(ya)(ya)作(zuo)用的(de)一(yi)款水(shui)泵，泛指能(neng)對管路的(de)液體進(jin)行提(ti)供額(e)外壓(ya)(ya)(ya)(ya)力的(de)泵的(de)統(tong)稱(cheng)，其用途主要(yao)有熱水(shui)器增(zeng)壓(ya)(ya)(ya)(ya)用、高樓低水(shui)壓(ya)(ya)(ya)(ya)、桑拿浴(yu)、洗浴(yu)等加(jia)壓(ya)(ya)(ya)(ya)用、公(gong)寓最上(shang)層水(shui)壓(ya)(ya)(ya)(ya)不足的(de)加(jia)壓(ya)(ya)(ya)(ya)、太陽能(neng)自動增(zeng)壓(ya)(ya)(ya)(ya)、反(fan)滲透(tou)凈水(shui)器增(zeng)壓(ya)(ya)(ya)(ya)用等等。增(zeng)壓(ya)(ya)(ya)(ya)泵并不指某一(yi)種類(lei)(lei)型的(de)泵，只要(yao)是泵都具(ju)有增(zeng)壓(ya)(ya)(ya)(ya)功能(neng)，所以(yi)增(zeng)壓(ya)(ya)(ya)(ya)泵包含的(de)泵類(lei)(lei)產品繁多(duo)(duo)，可(ke)以(yi)是管道泵、離心泵、污水(shui)泵、自吸泵、多(duo)(duo)級泵等類(lei)(lei)型泵。
增(zeng)(zeng)(zeng)壓(ya)(ya)泵(beng)(beng)(beng)(beng)(beng)在很多家(jia)庭中(zhong)都非(fei)(fei)常受用(yong)(yong)(yong)(yong)，尤其是(shi)一些高樓層的(de)(de)用(yong)(yong)(yong)(yong)戶幾乎都要用(yong)(yong)(yong)(yong)到增(zeng)(zeng)(zeng)壓(ya)(ya)泵(beng)(beng)(beng)(beng)(beng)。常規所指的(de)(de)增(zeng)(zeng)(zeng)壓(ya)(ya)泵(beng)(beng)(beng)(beng)(beng)分(fen)為：個人家(jia)庭安(an)裝(zhuang)使用(yong)(yong)(yong)(yong)的(de)(de)家(jia)用(yong)(yong)(yong)(yong)增(zeng)(zeng)(zeng)壓(ya)(ya)泵(beng)(beng)(beng)(beng)(beng)和(he)自來水(shui)(shui)公司供(gong)水(shui)(shui)或者(zhe)小區第(di)(di)二次供(gong)水(shui)(shui)安(an)裝(zhuang)使用(yong)(yong)(yong)(yong)的(de)(de)管道(dao)增(zeng)(zeng)(zeng)壓(ya)(ya)泵(beng)(beng)(beng)(beng)(beng)，也可以(yi)(yi)是(shi)工廠用(yong)(yong)(yong)(yong)水(shui)(shui)第(di)(di)二次增(zeng)(zeng)(zeng)壓(ya)(ya)使用(yong)(yong)(yong)(yong)的(de)(de)增(zeng)(zeng)(zeng)壓(ya)(ya)泵(beng)(beng)(beng)(beng)(beng)。增(zeng)(zeng)(zeng)壓(ya)(ya)泵(beng)(beng)(beng)(beng)(beng)的(de)(de)意思就(jiu)是(shi)在原來管道(dao)里面(mian)水(shui)(shui)壓(ya)(ya)的(de)(de)基礎上進行第(di)(di)二次增(zeng)(zeng)(zeng)壓(ya)(ya)的(de)(de)作用(yong)(yong)(yong)(yong)泵(beng)(beng)(beng)(beng)(beng)進口的(de)(de)壓(ya)(ya)力(li)加(jia)上增(zeng)(zeng)(zeng)壓(ya)(ya)泵(beng)(beng)(beng)(beng)(beng)所提供(gong)的(de)(de)壓(ya)(ya)力(li)就(jiu)是(shi)整個泵(beng)(beng)(beng)(beng)(beng)出口壓(ya)(ya)力(li)。增(zeng)(zeng)(zeng)壓(ya)(ya)泵(beng)(beng)(beng)(beng)(beng)可以(yi)(yi)分(fen)為立(li)式安(an)裝(zhuang)或者(zhe)臥(wo)(wo)式安(an)裝(zhuang)，最(zui)常用(yong)(yong)(yong)(yong)的(de)(de)家(jia)用(yong)(yong)(yong)(yong)增(zeng)(zeng)(zeng)壓(ya)(ya)泵(beng)(beng)(beng)(beng)(beng)就(jiu)是(shi)：WG型(xing)小型(xing)家(jia)用(yong)(yong)(yong)(yong)增(zeng)(zeng)(zeng)壓(ya)(ya)泵(beng)(beng)(beng)(beng)(beng)，最(zui)常用(yong)(yong)(yong)(yong)的(de)(de)第(di)(di)二次供(gong)水(shui)(shui)增(zeng)(zeng)(zeng)壓(ya)(ya)泵(beng)(beng)(beng)(beng)(beng)就(jiu)是(shi)：ISG管道(dao)增(zeng)(zeng)(zeng)壓(ya)(ya)泵(beng)(beng)(beng)(beng)(beng)、ISW臥(wo)(wo)式管道(dao)離心泵(beng)(beng)(beng)(beng)(beng)或者(zhe)目前(qian)新出來的(de)(de)DL立(li)式不銹鋼(gang)輕型(xing)多級泵(beng)(beng)(beng)(beng)(beng)。如果(guo)要讓非(fei)(fei)自吸式的(de)(de)增(zeng)(zeng)(zeng)壓(ya)(ya)泵(beng)(beng)(beng)(beng)(beng)達到自吸效果(guo)（泵(beng)(beng)(beng)(beng)(beng)位于水(shui)(shui)池上方），可以(yi)(yi)在泵(beng)(beng)(beng)(beng)(beng)的(de)(de)吸入(ru)口加(jia)裝(zhuang)底(di)閥即可。
二、什么是自吸泵
自(zi)(zi)(zi)吸(xi)(xi)(xi)泵(beng)(beng)(beng)(beng)(beng)屬自(zi)(zi)(zi)吸(xi)(xi)(xi)式離(li)心泵(beng)(beng)(beng)(beng)(beng)，就(jiu)(jiu)是(shi)把(ba)泵(beng)(beng)(beng)(beng)(beng)安(an)(an)裝在比液(ye)位高(gao)的地方(fang)、第(di)一次(ci)把(ba)泵(beng)(beng)(beng)(beng)(beng)體(ti)里面灌(guan)水(shui)(shui)之后(hou)啟動自(zi)(zi)(zi)吸(xi)(xi)(xi)泵(beng)(beng)(beng)(beng)(beng)能把(ba)水(shui)(shui)抽上來排走(zou)的泵(beng)(beng)(beng)(beng)(beng)，我們就(jiu)(jiu)把(ba)它(ta)統稱(cheng)為自(zi)(zi)(zi)吸(xi)(xi)(xi)泵(beng)(beng)(beng)(beng)(beng)，以(yi)后(hou)再使(shi)用就(jiu)(jiu)無需(xu)(xu)再次(ci)灌(guan)水(shui)(shui)即可啟動運(yun)行，自(zi)(zi)(zi)吸(xi)(xi)(xi)泵(beng)(beng)(beng)(beng)(beng)是(shi)否(fou)自(zi)(zi)(zi)吸(xi)(xi)(xi)要看停機后(hou)葉(xie)(xie)輪是(shi)否(fou)浸入水(shui)(shui)中，自(zi)(zi)(zi)吸(xi)(xi)(xi)泵(beng)(beng)(beng)(beng)(beng)就(jiu)(jiu)是(shi)因為有(you)(you)(you)獨特的泵(beng)(beng)(beng)(beng)(beng)腔結(jie)構而(er)可以(yi)保(bao)證(zheng)每(mei)次(ci)停機后(hou)葉(xie)(xie)輪都(dou)可以(yi)浸入水(shui)(shui)中才保(bao)證(zheng)了其自(zi)(zi)(zi)吸(xi)(xi)(xi)。自(zi)(zi)(zi)吸(xi)(xi)(xi)泵(beng)(beng)(beng)(beng)(beng)不(bu)但具(ju)有(you)(you)(you)自(zi)(zi)(zi)吸(xi)(xi)(xi)泵(beng)(beng)(beng)(beng)(beng)的功(gong)能并且還(huan)具(ju)有(you)(you)(you)增(zeng)壓(ya)泵(beng)(beng)(beng)(beng)(beng)的功(gong)能，所以(yi)我們也(ye)可以(yi)把(ba)自(zi)(zi)(zi)吸(xi)(xi)(xi)泵(beng)(beng)(beng)(beng)(beng)稱(cheng)為自(zi)(zi)(zi)吸(xi)(xi)(xi)增(zeng)壓(ya)泵(beng)(beng)(beng)(beng)(beng)。它(ta)具(ju)有(you)(you)(you)結(jie)構緊湊、操(cao)作(zuo)方(fang)便、運(yun)行平穩、維護容易、效率高(gao)、壽命長，并有(you)(you)(you)較強的自(zi)(zi)(zi)吸(xi)(xi)(xi)能力等優點。管路不(bu)需(xu)(xu)安(an)(an)裝底閥，工作(zuo)前(qian)只(zhi)需(xu)(xu)保(bao)證(zheng)泵(beng)(beng)(beng)(beng)(beng)體(ti)內儲有(you)(you)(you)定量(liang)引液(ye)即可。不(bu)同液(ye)體(ti)可采用不(bu)同材質自(zi)(zi)(zi)吸(xi)(xi)(xi)泵(beng)(beng)(beng)(beng)(beng)。
三、增壓泵和自吸泵的區別
1、從安裝位置來看
增(zeng)壓泵(beng)(beng)(beng)一般安(an)(an)裝(zhuang)在(zai)(zai)進水(shui)管道(dao)上，在(zai)(zai)原有(you)管道(dao)上剪(jian)斷(duan)一段后泵(beng)(beng)(beng)串聯到(dao)管路(lu)上即(ji)可(ke)，管道(dao)中間的水(shui)位(wei)高于泵(beng)(beng)(beng)體(ti)；自吸泵(beng)(beng)(beng)需安(an)(an)裝(zhuang)在(zai)(zai)回(hui)水(shui)管上，增(zeng)壓系統壓力，以(yi)助(zhu)其循環，用剪(jian)子剪(jian)斷(duan)一段管道(dao)，泵(beng)(beng)(beng)串聯到(dao)管路(lu)上即(ji)可(ke)，管道(dao)中間的水(shui)位(wei)低于泵(beng)(beng)(beng)體(ti)。
2、從適用范圍來看
增壓泵一般用(yong)(yong)在集中供暖系(xi)統上，以及(ji)太陽(yang)能(neng)落差小(xiao)導致水(shui)(shui)壓小(xiao)，以及(ji)熱水(shui)(shui)器(qi)水(shui)(shui)壓小(xiao)，需(xu)要增壓的情況下；自吸泵主要針對的是自采暖用(yong)(yong)戶(hu)(hu)，或者中大戶(hu)(hu)型(xing)家庭取暖系(xi)統循環、地(di)暖熱水(shui)(shui)循環使(shi)用(yong)(yong)。如果進(jin)水(shui)(shui)溫度可以、出(chu)水(shui)(shui)溫度較低，安裝自吸泵就可以解決問題，但是如果進(jin)回水(shui)(shui)溫度都低，那么需(xu)要先查(cha)找不(bu)熱的原(yuan)因(yin)。
3、從增壓強弱來看
增(zeng)壓(ya)泵主要解決(jue)水壓(ya)偏(pian)小的(de)(de)問題，屬于壓(ya)力偏(pian)小的(de)(de)類型泵，這主要是(shi)由(you)水泵結(jie)構(gou)決(jue)定的(de)(de)，增(zeng)壓(ya)泵是(shi)靠離(li)心力增(zeng)壓(ya)；而自吸泵相較增(zeng)壓(ya)泵壓(ya)力較大，可以帶動整個供(gong)暖系統(tong)的(de)(de)循環。
4、從產品操作來看
增(zeng)壓泵多是(shi)(shi)自(zi)(zi)動(dong)(dong)(dong)控(kong)制(zhi)，即開關是(shi)(shi)水流自(zi)(zi)動(dong)(dong)(dong)開關控(kong)制(zhi)，只要(yao)有水流動(dong)(dong)(dong)開關自(zi)(zi)動(dong)(dong)(dong)啟動(dong)(dong)(dong)，沒(mei)有水流動(dong)(dong)(dong)自(zi)(zi)動(dong)(dong)(dong)關閉；自(zi)(zi)吸(xi)泵大(da)多是(shi)(shi)手動(dong)(dong)(dong)控(kong)制(zhi)，需要(yao)人為開動(dong)(dong)(dong)開關，實現水泵接通運(yun)轉(zhuan)和停止運(yun)轉(zhuan)。
四、自吸泵和增壓泵哪個效果好
自吸(xi)泵和增(zeng)壓(ya)(ya)(ya)泵都(dou)可(ke)以對自來水(shui)進(jin)行增(zeng)壓(ya)(ya)(ya)，增(zeng)壓(ya)(ya)(ya)泵帶有(you)恒壓(ya)(ya)(ya)裝置，它能夠讓(rang)水(shui)管內(nei)的(de)水(shui)壓(ya)(ya)(ya)保持(chi)一個相對平(ping)均的(de)壓(ya)(ya)(ya)力。但自吸(xi)泵是(shi)不帶恒壓(ya)(ya)(ya)裝置的(de)，當(dang)在本來就有(you)水(shui)壓(ya)(ya)(ya)的(de)管道上裝它后，嚴重情況下會(hui)(hui)把水(shui)表玻璃都(dou)會(hui)(hui)吸(xi)碎掉。
如果(guo)水沒(mei)有斷(duan)流(liu)情況可(ke)以使用增(zeng)壓泵(beng)(beng)，如果(guo)經常斷(duan)流(liu)就要準備個容器（水池、水罐等），容器上可(ke)以裝(zhuang)(zhuang)排水管還可(ke)以使用增(zeng)壓泵(beng)(beng)，不能裝(zhuang)(zhuang)排水管就只能裝(zhuang)(zhuang)自吸(xi)泵(beng)(beng)。
適合選增壓泵的情況：
使(shi)用(yong)自(zi)來(lai)水的住戶：因為自(zi)來(lai)水是具有壓(ya)力的，尤其是住在高(gao)層的住戶，需(xu)要借助(zhu)增壓(ya)泵來(lai)增壓(ya)，讓壓(ya)力達到0.65MPa左右，才能實現正常使(shi)用(yong)。
適合選自吸泵的情況：
像很多農(nong)村家里(li)，還沒(mei)有通自(zi)來水(shui)的，只能使用(yong)井水(shui)，水(shui)井或水(shui)缸的位置比較低，那么(me)使用(yong)自(zi)吸泵的話，能夠將水(shui)自(zi)動吸進(jin)凈水(shui)器里(li)面。
另外，在購買(mai)自吸泵和(he)增壓泵時，也要注意以下一些事項：
購買增壓泵時，要(yao)向廠家提(ti)供(gong)自家的(de)供(gong)水管道(dao)的(de)型(xing)號、口徑(jing)以及自己所需(xu)要(yao)的(de)流量(liang)大小和揚程(cheng)，這樣廠家就(jiu)能根據(ju)用戶(hu)的(de)要(yao)求，給出一款合(he)適的(de)泵。
購買自吸泵(beng)(beng)時，基本也(ye)(ye)和(he)增(zeng)壓泵(beng)(beng)的購買注(zhu)意事項差不(bu)多，當然(ran)用(yong)戶也(ye)(ye)可以(yi)向廠家(jia)說明(ming)自己所想抽取的是什么(me)液體介質，這樣廠家(jia)就(jiu)能(neng)夠匹(pi)配(pei)出適合用(yong)戶的自吸泵(beng)(beng)，無(wu)論是抽取清水還是其他介質。
