What is the working principle of axial flow pump?
How it works: The wing is suspended in a fluid that flows at a certain speed with negative pressure on the surface and positive pressure on the back, the positive and negative pressure is related to the wing shape.
What is the working principle of axial flow pump? How it works: The wing is suspended in a fluid that flows at a certain speed with negative pressure on the surface and positive pressure on the back, the positive and negative pressure is related to the wing shape, the angle of attack and the inclination of the flow direction. When the fluid is stationary and the wing is moving in the fluid at the same speed, the back of the wing and the surface of the wing are subjected to the same positive and negative pressure as before, that is, the back of the wing (above the wing) is under the negative pressure and the back is under the positive pressure. Under this pressure the wing will gain lift. When the rotating shaft rotates at high speed, the wing surface (the lower side of the propeller) has the function of suction due to the negative pressure, and the wing back has the function of drainage due to the positive pressure.
