G型水泵為多級(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，尤其是各個(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。
