If the centrifugal pump does not use a volute, then the fluid leaves the impeller, the direction of its movement?
The concept is not clear, not clear.Impeller is generally a centrifugal pump and other vane pump concept, the impeller is outside the pressure chamber.Hydraulic cylinder generally high pressure, small flow, commonly used gear pumps, piston pumps and other displacement pumps.The deflector should be interpreted as a diversion device without rotation or energy exchange. The velocity should be calculated by the continuity equation and the pressure is calculated according to the conservation of energy
Centrifugal pump works: centrifugal pump is the use of impeller rotation and the centrifugal force generated by the water to work. Centrifugal pump before starting to pump shell and the water pipe filled with water, and then start the motor, the pump shaft to drive the impeller and water do high-speed rotation, water under the centrifugal force, was thrown to the outer edge of the impeller, the pressure water pipeline flow through the volute pump into the pump shell. The pump impeller at the center, due to action of water under the centrifugal force after being thrown into the vacuum suction tank in the water under the action of atmospheric pressure is pressed into the pump shell and the impeller rotates without stop by, make the water in the impeller under the effect of continuous inflow and outflow, achieve the purpose of water transport.
Centrifugal pumps: centrifugal force on the impeller rotates the transmission fluid pump.
If the volute is not used in the centrifugal pump, when the fluid leaves the impeller, its direction will follow the tangential direction at the outlet of the impeller (as shown).
