For different types of dry vacuum pumps, we are all eager to reduce their physical size. But this contradicts the pumping rate of the vacuum pump, because the pumping rate of the vacuum pump is proportional to the volume of the vacuum pump, small physical size means that the volume is also small....

The diffusion pump uses a high-speed steam direct injection pump to decompose the gas at the throat of the throat. In 1915, hosted by Wolfgang Gade and using mercury vapors, they were high vacuum free molecular flows in which the movement of gaseous molecules could be better understood than conve...
