SK型水環式真空泵的特點：

1、SK型水環式真空泵結構緊湊、維修方便；

2、SK型水環式真空泵應用范圍廣泛，可抽除含水蒸汽、易燃、易爆、含少量灰塵的、含少量液體的各種氣體；

3、SK型水環式真空泵主要用水作為工作介質，維護費用低；

4、SK型水環式真空泵可以在較為惡劣的環境下工作。

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?？蔀檎婵諢Y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.

該機組采用油做工作介質，對于怕油污染的真空環境，其使用受到了一定限制。但采用五氯酚苯基乙醚或五氯酚苯基硅氧烷為工作液，返油就會得到很大改善。也可以采用水冷擋板，再裝一個簡單的液氮阱，可使返油率小于5×10-6mg/cm2．因而可更廣泛地應用于光學工業、電子工業、真空冶金、航天及原子能工業中。

Oil is used as medium for this unit, so there is some restriction for the use under vacuum environment which should be avoid of oil pollution.But the use of PCP phenol ether or PCP phenol silicone as working solution and oil back-streaming could be improved greatly.min。

Water-cooling baffle could be also used, and the installation of a simple liquid nitrogen trap could make oil back-streaming rate less then 5 ×10-6mg/cm2.min.So it can be also widely applied in the industries such as optics, electronics, vacuum metallurgy, aerospace and nuclear industry.
