Axial flow impeller rotation is the use of the water body to produce thrust (lift) Work of low-lift pump variable flow pumps, vertical, horizontal, inclined and Tubular several species. Vertical Axial which depends mainly on the blade lift will lead to fluid outlet is axially into axial out, with the advantages of large flow. Axial pump works: axial fluid flow into the blade passage, when the impeller rotates in the prime mover driven, rotating blades to the fluid flow around an axial reasoning, reasoning secondary fluid leaves work, so that the energy of the fluid increases and axial discharge, continuous rotation of the impeller, which form continuous axial flow pump. General characteristics of axial flow pump: 1) water flowing along the direction of axial flow impeller shaft is inhaled, the outflow axis, so called axial flow; head low (1 to 13 m), large flow, high efficiency suitable for plain, lake, river drainage area; 2) before the start without irrigation, simple operation. Variable stator vane pump surface is a circular variable pump. Between service calls, the rotor and stator has eccentricity, the oil pan is only open a window and a suction pressure of the oil window. When the rotor rotates in the direction of the arrow driven by the electric motor, the stator vane through the lower half, the centrifugal force of the variable displacement pump. Specialist, extending from the blade groove, sealed volume between the two blades is increased, to achieve Suction; stator blade through the upper half, was gradually pressed into the surface of the stator blade slots, sealed volume reduction and achieve oil pressure. Each turn a pump rotor of the pump transition Nursing, each sealed volume suction, pressure oil each time. Changing the amount of eccentricity between the stator and rotor, you can change the pump displacement, so called variable vane pump [2]. Variable pump.
