Quick Answer. A rotary vane vacuum pump works by using centrifugal force to turn blades against the circular surface of a cylinder whereby pockets of air are pushed from an inlet port to an outlet port as air pressure increases.
How Hydraulic Rotary Vane Actuators Work. Hydraulic rotary vane actuators use a system of vanes to produce force by means of hydraulics. Pneumatic applications are useful in situations where large amounts of force at not required. For more muscle, hydraulics are the type of cylinder actuators you want.In both types a closed chamber resides on both ends of a shaft. Applying pressure to one side moves the shaft in the desired rotary direction.neumatic applications are useful in situations where large amounts of force at not required.
