真空泵是指利用機(jī)械、物理、化學(xué)或物理化學(xué)的方法對(duì)被抽容器進(jìn)行抽氣而獲得真空的器件或設(shè)備。通俗來(lái)講，真空泵是用各種方法在某一封閉空間中改善、產(chǎn)生和維持真空的裝置。
按真空泵的工作原理，真空泵基本上可以分為兩種類(lèi)型，即氣體捕集泵和氣體傳輸泵。其廣泛用于冶金、化工、食品、電子鍍膜等行業(yè)。
2BEA、2BVA、SZ、2S、2SK系列水環(huán)真空泵，除與羅茨泵或氣冷泵組成2-4級(jí)羅茨水環(huán)或羅茨氣冷水環(huán)機(jī)組外，亦可獨(dú)立組成水環(huán)泵閉環(huán)或開(kāi)環(huán)成套機(jī)組（含防爆型）。
Model 2BEA, 2BVA,SZ, 2S, 2SK water ring vacuum pump series could be assumed into 2-4 stages vacuum pump unit with roots vacuum pump or air cooled pump and also could be water ring closed-loop or open-loop unit (include the explosion-proof type) independently.
該機(jī)組可配套提供JZ系列油擴(kuò)散噴射泵真空機(jī)組（又稱(chēng)油增壓泵機(jī)組）。該機(jī)組抽氣能力大、粗抽時(shí)間短、設(shè)備維護(hù)簡(jiǎn)單、操作方便，是真空應(yīng)用設(shè)備的理想配套設(shè)備。但該機(jī)組不適于排除對(duì)金屬有腐蝕作用及對(duì)泵油產(chǎn)生化學(xué)反應(yīng)的氣體。現(xiàn)廣泛地被太陽(yáng)能制品企業(yè)所應(yīng)用。
This unit comes with JK serial oil diffusion jet vacuum pump unit (also called oil booster unit).It has good capacity of gas extracting, with short rough extracting, easy to maintain and operating. It is ideal corollary equipment for vacuum application equipment.But this unit is not suitable for the gases which exclude corrosion towards metals and chemical reaction towards pump oil.Now it is widely applied by solar product enterprises.
