In addition to pumping air and no condensate and other non-corrosive gases, widely used in pumping speed and the need for high vacuum of truth in this system.
适用于抽除空气及其它无可凝性及无腐蚀性的气体，广泛应用于需要大抽速和高真空的各种真这系统中。

The Neutral Beam Injection (NBI) system requires a clean high vacuum environment. The liquid helium cryocondensation pump with high pumping speed is an ideal vacuum obtain device.
中性束注入系统要求有洁净的动态高真空环境，大抽速液氦冷凝泵是满足此要求的理想真空获得设备。
