Mixed flow pump is to rely on the centrifugal force and axial thrust to transport the liquid mixture, so called mixed flow pump.
(1) mixed-flow pump working principle From the working principle, when the prime mover driven impeller rotation, the role of the liquid both centrifugal force and axial thrust, is a combination of centrifugal pump and axial flow pump. It is therefore a pump between the centrifugal pump and the axial pump. Mixed flow pump than the centrifugal pump speed, lower than the axial flow pump, usually between 300-500. Its lift is higher than the axial pump, but lower than the centrifugal pump axial flow pump smaller than the centrifugal pump. Mixed flow pump is mainly used for agricultural irrigation and drainage, in addition to urban drainage, can be used as a circulating pump for thermal power plants.
(2) Type and structure of mixed flow pump Mixed flow pump has two types of mixed flow pump and guide vane mixed flow pump. Volute-type} Kun flow pump mainly by the pump, pump cover, impeller, pump shaft, bearing body and shaft seal device and other components.
Guide vane type mixed flow pump also known as diagonal flow pump. Guide vane type mixed flow pump and volute difference, mainly in the pump body, with several usually vaulted vane space guide vane device. Liquid from the impeller through the vane after the axial flow. Cylinder shape cylinder, but looks like a big bellied drum, a bit like axial flow pump. This pump is generally horizontal and vertical two kinds of internal structure is basically the same. Most of the large caliber made upright. Small diameter vertical guide vane type mixing pump shape is very similar to the centrifugal type shallow well pump, this pump structure is simple, easy to move, suitable for farmland irrigation and drainage, it is called mixed flow farming pump.
