Momentum transfer pump

Rely blades rotating at high speed or high-speed jet, the momentum transfer to the gas or gas molecules,gas transfer pump , so that continuously transferred from the gas inlet to the pump outlet. Such pumps can be divided into the following form,

 Molecular pump
It is the use of high-speed rotation of the rotor to transfer momentum to the gas molecules, and thus obtain the orientation speed,automated fuel management system , so as to be compressed, is driven towards the exhaust port of the preceding stage is drawn away after a vacuum pump. This pump concrete can be divided into,

1) traction molecular pump and high-speed movement of gas molecules collide and get momentum rotor is driven to the pump outlet.

2) turbo molecular pump by high-speed rotation of the rotor blades and the stationary blade with each other to achieve a given pumping. Such pumps are typically operate at the molecular flow state.fuel dispensing pump

3) It is composed of complex molecular pump turbo molecular pump and traction type two series combination of a complex type of molecular pump.
