what is the principle of axial flow pump?

the working principle of axial flow water pump factory is the use of the impeller when the rotating blades of water to produce lift, lift will energy to the water, the axial flow pump can find water. Visible, axial flow water pump does not use the centrifugal force, but to take advantage of the impeller rotation to generate lift to flush.

for horizontal axial flow pump has a suction pipe, when the water push back in the impeller rotating impeller, the impeller is created in front of the certain vacuum low pressure area. And on the surface of the water source is the atmospheric pressure, high pressure water always flows to the lower pressure. Therefore, the water in the water under the action of atmospheric pressure, through be sucked in the pump inlet pipe road, fill the impeller center of low pressure area, this is the axial flow pump suction process. It as the principle of centrifugal pump suction and impeller near the back pressure is lower, its suction.

axial flow pump according to the direction of the pump shaft can be divided into vertical, horizontal and diagonal type three kinds of structure; According to its blade can mediate different and regulating mechanism can be divided into stationary blade, blade adjustable and fully adjustable blade 3 kinds. General for whole stationary blade impeller casting and become, structure is simple, but the casting more difficult, more for small axial flow pump. Blade adjustable impeller blades and separate manufacturing hub. More than half of the adjustment type impeller blade used for medium and small axial flow pump, fully adjustable blade impeller used in medium and large axial flow pump. Due to the vertical axial flow pump cover an area of an area small, uniform bearing wear, impeller submerged in the water, start don't need water, can also adopt a type bearing way, will be effected according to the change of the water level in the middle of the rotating shaft connected with appropriate length pump and engine,
