如何選擇離心泵廠家？

1、選擇水箱(xiang)、水塔的提升泵應盡(jin)量減(jian)少泵的臺(tai)數，宜(yi)一用(yong)一備；當(dang)單(dan)泵可以滿足要(yao)求時，則不宜(yi)采用(yong)多臺(tai)并(bing)(bing)聯方(fang)式；若必須采用(yong)多臺(tai)并(bing)(bing)聯運(yun)(yun)行(xing)(xing)或大(da)小泵搭配方(fang)式時，其型(xing)(xing)號(hao)、臺(tai)數不宜(yi)過(guo)多，型(xing)(xing)號(hao)一般不宜(yi)超過(guo)兩種，水泵的揚(yang)程范圍應相近；并(bing)(bing)聯運(yun)(yun)行(xing)(xing)時每臺(tai)泵宜(yi)仍(reng)在高效區范圍內運(yun)(yun)行(xing)(xing)。

2、電源須可靠（雙電源或雙回路供(gong)電）；水(shui)(shui)泵(beng)(beng)的工(gong)作點(dian)(dian)應選在(zai)水(shui)(shui)泵(beng)(beng)特(te)(te)性曲(qu)線(xian)(xian)（Q-H曲(qu)線(xian)(xian)）的高效工(gong)作區(qu)內(nei)，并不得選在(zai)Q-H曲(qu)線(xian)(xian)的延(yan)長(chang)線(xian)(xian)上，設計的不利工(gong)作點(dian)(dian)應在(zai)水(shui)(shui)泵(beng)(beng)特(te)(te)性曲(qu)線(xian)(xian)高效區(qu)段(duan)的右端點(dian)(dian)，即水(shui)(shui)泵(beng)(beng)出水(shui)(shui)量(liang)(liang)大、而揚程較低但能滿足要求的那(nei)個點(dian)(dian)，也就是水(shui)(shui)泵(beng)(beng)特(te)(te)性曲(qu)線(xian)(xian)高效區(qu)的低點(dian)(dian)與管(guan)道(dao)特(te)(te)性曲(qu)線(xian)(xian)的交叉點(dian)(dian)。水(shui)(shui)泵(beng)(beng)調速(su)工(gong)作范(fan)圍能盡量(liang)(liang)在(zai)水(shui)(shui)泵(beng)(beng)高效段(duan)內(nei)；調速(su)范(fan)圍宜設在(zai)水(shui)(shui)泵(beng)(beng)供(gong)水(shui)(shui)量(liang)(liang)的25%～100%之(zhi)間；設備(bei)應具有水(shui)(shui)位自動控制功能。
