在集中供暖系統中,由于熱源較遠,常出現循環水壓不足,家中采暖溫度不達標的現象,因此需要在采暖主管分支入戶處增加鈦強制循環泵,而鈦強制循環泵安裝在回水管路上是理想方式。這是因為:
1、保護循(xun)(xun)環(huan)泵(beng)(beng)(beng)安全,減少高溫(wen)對循(xun)(xun)環(huan)泵(beng)(beng)(beng)的傷害。供水管中的水溫(wen)比回(hui)水溫(wen)度要高很多(duo),循(xun)(xun)環(huan)泵(beng)(beng)(beng)屬于電器設備,高溫(wen)會影響(xiang)設備的正常工作,鑒于供回(hui)水溫(wen)度不一樣,很顯(xian)然將循(xun)(xun)環(huan)泵(beng)(beng)(beng)安裝在回(hui)水管路對水泵(beng)(beng)(beng)的影響(xiang)較(jiao)小。
2、保護供暖(nuan)(nuan)(nuan)系(xi)(xi)(xi)統(tong)(tong)(tong)(tong),減少(shao)對(dui)供暖(nuan)(nuan)(nuan)系(xi)(xi)(xi)統(tong)(tong)(tong)(tong)的(de)(de)沖(chong)擊。供暖(nuan)(nuan)(nuan)系(xi)(xi)(xi)統(tong)(tong)(tong)(tong)是有(you)一定的(de)(de)阻力(li)的(de)(de),如果將(jiang)循(xun)環泵安(an)裝在供水管路,在循(xun)環泵工作時,強勁的(de)(de)水流(liu)推(tui)動力(li)必然沖(chong)擊用(yong)戶家中(zhong)的(de)(de)供暖(nuan)(nuan)(nuan)系(xi)(xi)(xi)統(tong)(tong)(tong)(tong),而由(you)于(yu)供暖(nuan)(nuan)(nuan)系(xi)(xi)(xi)統(tong)(tong)(tong)(tong)的(de)(de)阻力(li),這樣很可能(neng)使供暖(nuan)(nuan)(nuan)系(xi)(xi)(xi)統(tong)(tong)(tong)(tong)承受很大的(de)(de)壓力(li)。不(bu)僅(jin)阻礙系(xi)(xi)(xi)統(tong)(tong)(tong)(tong)正常循(xun)環,還(huan)可能(neng)使供暖(nuan)(nuan)(nuan)系(xi)(xi)(xi)統(tong)(tong)(tong)(tong)漏水。循(xun)環泵裝在回水管路上,能(neng)夠解決(jue)用(yong)戶家中(zhong)供暖(nuan)(nuan)(nuan)系(xi)(xi)(xi)統(tong)(tong)(tong)(tong)的(de)(de)水壓問(wen)題,多余的(de)(de)壓力(li)會隨著供暖(nuan)(nuan)(nuan)系(xi)(xi)(xi)統(tong)(tong)(tong)(tong)的(de)(de)主(zhu)管向熱源處排走。
3、利于(yu)供暖(nuan)系統進行(xing)排污(wu)(wu)。供暖(nuan)管(guan)(guan)(guan)(guan)路(lu)中難免會進入(ru)一(yi)些(xie)污(wu)(wu)垢,而這些(xie)污(wu)(wu)垢會在水流較平緩的位置附著,不易排出(chu),在供暖(nuan)管(guan)(guan)(guan)(guan)路(lu)中,回水管(guan)(guan)(guan)(guan)路(lu)就屬(shu)于(yu)水流較平緩的位置,其動壓(ya)要低于(yu)供水管(guan)(guan)(guan)(guan)路(lu),因(yin)此將(jiang)鈦(tai)強制循環泵安裝在回水管(guan)(guan)(guan)(guan)路(lu),有利于(yu)污(wu)(wu)垢從(cong)供暖(nuan)系統中排出(chu),延長供暖(nuan)系統的使用壽命(ming)。
需要注意(yi)的是(shi),在(zai)集中(zhong)供暖(nuan)中(zhong),不要私(si)自安裝鈦(tai)強制循環泵,可能會導(dao)致回水不循環,影響其他住戶的正(zheng)常采(cai)暖(nuan)。
