該機組可配套提供JZ系列油擴散噴射泵真空機組（又稱油增壓泵機組）。該機組抽氣能力大、粗抽時間短、設備維護簡單、操作方便，是真空應用設備的理想配套設備。但該機組不適于排除對金屬有腐蝕作用及對泵油產生化學反應的氣體。現廣泛地被太陽能制品企業所應用。

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.

1、比較SK系列單級水環真空泵而言，具有真空度高、在高真空區抽速大等特點。

2、相同抽速率下，軸功率明顯高于2BV、2BE系列水環式真空泵。

3、因結構為雙葉輪結構，制造、維修較為復雜，易損件較多。

2SK型水環式真空泵被廣泛應用于食品、紡織、化工、醫藥和冶金工業及電子領域的真空蒸發、真空濃縮、真空回潮、真空浸漬、真空干燥及真空冶煉等。

2SK系列使用于吸入壓力低于-0.08MPa的工況條件，2SK-P1系列使用于吸入壓力低于-0.096MPa的工況條件。

該機組具有結構緊湊，操作靈活可靠，使用方便等特點，廣泛應用于電子工業、冶金工業、化學工業、原子能工業以及宇航等科研技術領域。可為真空燒結爐，各種真空鍍膜機以及真空電子束焊機、各類真空電爐、電子顯微鏡、各種電子射線、加速器、宇宙空間模擬容器所需之高真空環境均可用JK系列擴散泵真空機組來實現。

This unit has the features such as compact structure, flexible and reliable operation, easy to use. It is widely applied in electronic industry, metallurgy industry, chemical industry, nuclear industry and in scientific research technology fields such as aerospace.The ultra vacuum environment required by vacuum sintering furnace, vacuum coating machine, vacuum electron-beam welder, various vacuum furnace, electron microscope, various electron rays, accelerators and space simulation chamber could be achieved by JK serial diffusion vacuum pump unit.
