SK型水环式真空泵的特点：

1、SK型水环式真空泵结构紧凑、维修方便；

2、SK型水环式真空泵应用范围广泛，可抽除含水蒸汽、易燃、易爆、含少量灰尘的、含少量液体的各种气体；

3、SK型水环式真空泵主要用水作为工作介质，维护费用低；

4、SK型水环式真空泵可以在较为恶劣的环境下工作。

该机组具有结构紧凑，操作灵活可靠，使用方便等特点，广泛应用于电子工业、冶金工业、化学工业、原子能工业以及宇航等科研技术领域。可为真空烧结炉，各种真空镀膜机以及真空电子束焊机、各类真空电炉、电子显微镜、各种电子射线、加速器、宇宙空间模拟容器所需之高真空环境均可用JK系列扩散泵真空机组来实现。

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.

该机组采用油做工作介质，对于怕油污染的真空环境，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为工作液，返油就会得到很大改善。也可以采用水冷挡板，再装一个简单的液氮阱，可使返油率小于5×10-6mg/cm2．因而可更广泛地应用于光学工业、电子工业、真空冶金、航天及原子能工业中。

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.
