Present situation and development of oil vapour diffusion vacuum pump

油扩散泵的现状及发展

Maintenance of oil vapour diffusion vacuum pump

油扩散泵的维修

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。
