Webb1 nov. 1991 · Summary. Models for jet pumps currently are derived under the assumption that the power and well fluids are incompressible liquids that, in many cases, are assumed to have equal densities. When either the well or the power fluid contains gas, current design practices still use the equations for incompressible liquids and account for the presence … WebbIon pumps use a four-step process to remove gases from the vacuum chamber. Step 1: Create a high magnetic field. The ion pumps have magnets located outside the vacuum. Those magnets generate a 1200 gauss magnetic field, which contains and guides electrons within circular anode rings. Step 2: Generate a plasma.
