The diffusion pump’s pressure is 100~10-7mmHg, the stable working pressure range is 5x10-4~5x10-6mmHg. So, we need to set a right pressure for the pump, and not allowed it working a long time under the pressure of 10-8mmHg.


4.  All the gas which produced by the vacuum equipment of the fuel truck and water truck could come into the vacuum pump.
