油扩散泵
Introduces the newly developed K-800A HV oil diffusion pump for its design of broadened range of pumping speed, increased critical backing pressure and reduced backstreaming rate.
介绍了新研制的高真空油扩散泵在拓宽抽气速率范围、提高临界前级压力、降低返油率方面的创新设计。
The oil vapor contamination in the old vacuum furnace was inherited from its oil diffusion pump, and the inaccuracy temperature control of the furnace chamber was resulted from the manual temperature adjust-ment. These problems have severely restricted the development of vacuum technology in our laboratories.
老式真空炉由于采用了油扩散泵和手动控温方式,存在真空系统被油污染和控温精度差的问题,严重影响了真空工艺质量。
