稱水環(huán)泵。水環(huán)泵首要用于粗真空、抽氣量大的工藝進(jìn)程中。在化工、石油、輕工、及食品工業(yè)中得到了廣泛地應(yīng)用,如真空過濾、真空送料、真空濃縮、真空脫氣等。單級(jí)水環(huán)泵的極限壓力可達(dá)8~2×103Pa,雙級(jí)水環(huán)泵的極限壓力可達(dá)1×102Pa,排氣量為0.25~500m3/h。水環(huán)式真空泵的作業(yè)原理水環(huán)泵作業(yè)輪2在泵體1中旋轉(zhuǎn)時(shí)構(gòu)成了水環(huán)3和作業(yè)室5。水環(huán)與作業(yè)輪構(gòu)成了月牙形空間。右邊半個(gè)月牙形的容積由小變大,構(gòu)成吸氣室。左邊的半個(gè)月牙形的容積由大變小,構(gòu)成了緊縮進(jìn)程(相當(dāng)于排氣室)。被抽氣體由進(jìn)氣管8和進(jìn)氣口4進(jìn)入吸氣室。轉(zhuǎn)子進(jìn)一步滾動(dòng),使氣體受緊縮,經(jīng)過排氣口6和排氣管7排出。排出的氣體和水滴由排氣管道7進(jìn)入水箱10。

雙吸葉輪的利益就是相同轉(zhuǎn)速與流量的情況下,由于減小了進(jìn)水口的流速、雙吸泵很難呈現(xiàn)汽蝕現(xiàn)象。雙吸泵的運(yùn)用規(guī)劃與臥式離心泵相同,流量規(guī)劃為90~3000m3/h,揚(yáng)程規(guī)劃為10-140m。其特點(diǎn)是流量大,檢修便當(dāng),而且檢修時(shí)只需翻開泵蓋即可取出轉(zhuǎn)子,不需要拆開電動(dòng)機(jī)和銜接管路。按軸的設(shè)備方位不同,這種離心泵可分立式雙吸泵和臥式雙吸泵兩種結(jié)構(gòu)。臥式S型單級(jí)雙吸離心泵結(jié)構(gòu)圖。單級(jí)雙吸離心泵泵體是水平剖分的螺旋形蝸殼,兩個(gè)呈半螺旋形的吸液室與泵殼一同為中開式。泵軸水平放置,軸的兩端支撐在裝有軸承的軸承座內(nèi),雙吸式葉輪置于泵軸中心。泵的口及排出口分別安頓鄙人半個(gè)泵殼的兩端,泵體和葉輪兩端都裝有密封環(huán),軸封設(shè)備為填料密封。
