螺桿泵依靠螺桿相互嚙合空間的容積變化來(lái)輸送液體。當(dāng)螺桿轉(zhuǎn)動(dòng)時(shí)吸入腔一端的密封線連續(xù)地向排出腔一端作軸向移動(dòng)，使吸入腔的容積增大，壓力降低，液體在壓差作用下沿吸入管進(jìn)入吸入腔。隨著螺桿的轉(zhuǎn)動(dòng)，密封腔內(nèi)的液體連續(xù)而均勻地沿軸向移動(dòng)到排出腔，由于排出腔一端的容積逐漸縮小，即將液體排出。

5. 配套電機(jī)的選配
泵的選型確定后，根據(jù)樣本數(shù)據(jù)可查到泵的軸功率N，該軸功率再加上一定的功率儲(chǔ)備后，作為選配電機(jī)的依據(jù)，一般電機(jī)功率Nm應(yīng)不小于泵軸功率N乘以功率儲(chǔ)備系數(shù)K后所得值，K值可參照下

· 三螺桿泵的流量、壓力在相同轉(zhuǎn)速、粘度時(shí)近似呈直線關(guān)系，壓力越高，流量越小。
· 相同粘度、壓力下，泵的流量與轉(zhuǎn)速近似成正比。
· 相同轉(zhuǎn)速、粘度下，軸功率與壓力近似成正比。
· 同一粘度、壓力下，軸功率與轉(zhuǎn)速近似成正比。
· 粘度增大時(shí)，流量和軸功率均增加，但由于其中關(guān)系較復(fù)雜，必要時(shí)可向?qū)I(yè)人員咨詢。
只要選型得當(dāng)，維護(hù)合理，三螺桿泵就可達(dá)到令人滿意的運(yùn)行效果。
