Rotary Vane Vacuum Pumps
Rotary vane pumps are comprised of a series of vanes that are mounted to a rotor that turns inside a cavity. As the vanes rotate, centrifugal force extends them from their individual slots, forming compression cells that get larger to draw air in from the intake and smaller to push air out the exhaust.
🔹
Articulated Piston
An articulated piston industrial vacuum pump operates in a manner similar to that of an automobile engine. As the piston moves downward inside the cylinder, air is drawn in through the intake valve. During the piston's upward stroke, the air is permitted to escape via an exhaust valve.
🔹
Screw Vacuum Pumps
Rotary screw pumps include two parallel rotary screws in the pump housing. The screws are synchronized to turn in opposite directions, which causes the compression action to occur. The gas is compressed in the direction of the pump's discharge port.
🔹
Liquid Ring Pumps
Liquid ring pumps also operate via positive displacement. During operation, the pump's impeller rotates inside the pump casing. A rotating liquid ring then seals the impeller and its blades. Conveyed gas is compressed during each impeller revolution.
