一、DF型鍋爐給水泵產(chǎn)品概述:
DF型鍋爐給水泵,供輸送清水及物理化學(xué)性質(zhì)類似于水的液體之用。本型水泵揚(yáng)程在46至576米時(shí),流量為6至55米/小時(shí),液體的最高溫度低于110適合于鍋糧給水,軾廠及城市給水之用。水泵配用Y型電動(dòng)機(jī)。目前所制造的DF型泵有:11/2D-5,21/2D6及4D8等共4種。 結(jié)構(gòu)說(shuō)明:DF型不銹鋼水泵為多級(jí)分段式,其吸入口位于進(jìn)水段上,吐出口在出水段上均垂直向上,其揚(yáng)程機(jī)根據(jù)使用而增減水泵級(jí)數(shù)。水泵裝配良好瑟否,對(duì)性能影響關(guān)系很大,萬(wàn)其是各個(gè)葉輪的出口與導(dǎo)葉進(jìn)口之寧肯對(duì)位置,每級(jí)葉輪的吐出口中心必須對(duì)準(zhǔn)導(dǎo)葉的中心,其中稍有偏差即將使水段上均直向上,其揚(yáng)程可根據(jù)使用而增減水泵級(jí)數(shù)。水泵裝配良好與否,對(duì)性能影響關(guān)系很大,尤其是各個(gè)葉輪的出口與導(dǎo)葉進(jìn)口之相對(duì)位置,每級(jí)葉輪的吐出口中心必須對(duì)準(zhǔn)導(dǎo)葉的中心,其中稍有偏差即將使水泵的流量減少,揚(yáng)程降低,效率差,故在檢修裝配時(shí)務(wù)必注意,若有偏差必須調(diào)整。
二、鍋爐給水泵型號(hào)意義:
例如:DF6-25×6
DF-不銹鋼多級(jí)泵
6-流量(m3/h)
25-單級(jí)揚(yáng)程(米)
6-泵級(jí)數(shù)
