我们做成了一个高速旋转真空密封装置,现已把它移置于正在研制的强流中子发生器装置中。转靶的空载运转表明,密封是成功的。密封装置情况如图1所示。用扩散泵(抽速限制为100升/秒)对主真空室抽气,另一台2×4机械泵对密封的差动密封腔抽气,皮带传动的密封轴转动时,系统的真空达 We have made a high-speed rotary vacuum seal that has now been moved to the developing high-flow neutron generator unit. No-load operation of the target shows that the seal is successful. The sealing device is shown in Figure 1. The main vacuum chamber is evacuated with a diffusion pump (pumping speed limited to 100 liters / second) and the other 2 × 4 mechanical pump is sucked into the sealed differential seal chamber. When the belt-driven sealing shaft rotates, the vacuum of the system
