2BE1S水環(huán)式真空泵

　2BE1S系列水環(huán)式真空泵是在2BE1系列基礎上拓展設計的雙級單作用水環(huán)式真空泵。2BE1系列真空泵極限壓力為3300Pa，理想工作壓力范圍20Kpa-100Kpa，當入口壓力低于20Kpa時(shí)，抽氣量迅速衰減，此時(shí)選用單級水環(huán)真空泵效率極低。2BE1S系列水環(huán)真空泵設計兩級壓縮過(guò)程，在較高的真空度范圍內抽速平穩，或者在很大的抽氣速率范圍內維持較高的真空度。在較高真空工作狀態(tài)時(shí)效率較單級水環(huán)泵提高35%至40%，能耗也相應降低。

工作原理

　　2BE1S雙級水環(huán)真空泵吸排氣工作原理與2BE1 單級水環(huán)真空泵相同。在葉輪作旋轉時(shí),腔體內壁形成與葉輪成偏心的水環(huán)，充滿(mǎn)在葉片間的水，隨著(zhù)葉輪的旋轉，在葉片之間不斷地作周期性的往復運動(dòng).改變葉片中間的容積大小，在固定的吸氣口和排氣口的相應配合下，完成吸氣、壓縮和排氣過(guò)程。而雙級的作用是經(jīng)第一級壓縮排出的氣體被第二級吸氣口吸入，然后經(jīng)過(guò)第二級的進(jìn)一步壓縮后排出，第二級的作用是減少第一級排氣壓強，以提高第一級吸入口的真空度。

2BE1S雙級水環(huán)真空泵的特點(diǎn)

　　極限壓力可達2Kpa，入口工作壓力范圍5Kpa-20Kpa

　　200-7500m3/h多種規格，滿(mǎn)足各種工藝需要

　　不銹鋼、雙相鋼、鈦材、哈氏合金等多種材質(zhì)選擇

　　可靠的葉輪鎖緊防松方式

　　兩端機械密封，多種沖洗方案選配

　　標配防汽蝕裝置

　　性能可靠，高效節能

　　精密鑄件、進(jìn)口軸承、高標配件

應用領(lǐng)域

　　完美的設計，合理的結構，可靠的性能，特別適用于化工、食品、制藥、紡織、電力、造紙、冶金、儀器等各種行業(yè)的真空干燥、濃縮、蒸發(fā)、蒸餾、脫水、脫氣、過(guò)濾等工藝。

　　作為羅茨真空泵的前級泵使用效果尤為理想。

典型應用

　　配套蒸發(fā)器的真空蒸發(fā)/精餾工藝

　　蒸發(fā)器真空系統一般要求入口真空度在6-10Kpa之間有較大的抽氣量。單級水環(huán)真空泵在這一區間抽氣能力已相當弱，而選用雙級水環(huán)真空泵此時(shí)發(fā)揮出最大的抽氣能力。同等能耗下效率提高30%以上。

　　精細化工塔頂常減壓真空裝置

　　常減壓蒸餾真空裝置也要求在較低真空度時(shí)有較大的抽氣能力。即使選用單級水環(huán)式真空泵帶一級大氣噴射器，在吸入壓力為5kPa-6Kpa時(shí)的抽氣速率也只有該泵最大的65--70%。所以雙極水環(huán)真空泵是常減壓蒸餾真空裝置的理想選擇。

　　電廠(chǎng)汽輪機凝汽器抽真空裝置

　　當前電廠(chǎng)凝汽器抽真空主要采用2BE1系列水環(huán)真空泵串聯(lián)一級大氣噴射器的方式，配置大氣噴射器真空度提高了，但抽氣效率降低，能耗高。2BE1S系列雙級水環(huán)泵最大氣量可達7500m3/h，選配優(yōu)質(zhì)換熱器、儀表閥門(mén)，滿(mǎn)足高可靠性的使用要求。

　　配套羅茨真空泵組成的羅茨機組

　　羅茨真空機組選用雙級水環(huán)泵輔以?xún)?yōu)質(zhì)的控制系統，是保證機組長(cháng)期平穩運行的關(guān)鍵。目前水環(huán)羅茨機組一般采用2BE1和2BV系列水環(huán)真空泵作為前級泵，運行中羅茨泵過(guò)載、發(fā)熱，壽命短。配用2BE1S系列雙級水環(huán)泵較低入口壓力下有較大的抽氣能力，即降低羅茨泵的排氣壓力，使羅茨泵始終在壓差允許范圍內運行，無(wú)過(guò)載發(fā)熱，保證機組安全可靠運行。

雙級液環(huán)泵和單級液環(huán)泵的比較與選擇

　　雙級和單級水環(huán)真空泵是針對不同的使用工況設計開(kāi)發(fā)的。從上述曲線(xiàn)看出單級水環(huán)真空泵在較高真空度(小于20000Pa)范圍內，抽速衰減嚴重，在5000至10000Pa時(shí)甚至不足最大抽速的30%，在此工況下效率極低，功耗較高。但在粗真空狀態(tài)下又顯示出其抽氣量大的優(yōu)勢。而雙級水環(huán)真空泵，在較高的真空度范圍內能獲得更大的抽速，或者在很大的抽氣速率范圍內維持較高的真空度。在較高真空工作狀態(tài)時(shí)效率較單級水環(huán)泵提高35%至40%，能耗也相應降低。因此應根據使用條件選擇合適的真空泵才能降低能耗經(jīng)濟運行。
