Volute mixed flow pump is mainly composed of impeller, pump cover, pump body, pump shaft, bearing and sealing device. The shape and components of the mixed flow pump are similar to those of the single suction centrifugal pump, the main difference lies in the shape of the impeller: the impeller of the mixed flow pump is between the impeller of the centrifugal pump and the impeller of the axial flow pump, its flow channel is inclined to the axis of the pump shaft, and the water enters the impeller from the axial direction and flows out from the inclined direction, which makes use of the centrifugal force and the thrust force.
The mixed flow pump has the advantages of simple structure, small volume, light weight and convenient operation and maintenance. Its working characteristics are: the flow is greater than the centrifugal pump, less than the axial flow pump, the head is less than the centrifugal pump, more than the axial flow pump, so it is more suitable for use in the plain area with the head of 5-10 meters, and is a more popular agricultural pump. The water pump adopts vertical shaft single foundation structure with vertical motor. The motor is directly set on the water pump, which avoids the disadvantage that the old pump motor and water pump are respectively placed in the upper and lower floors for operation, and the installation and maintenance are extremely inconvenient. The product has high operation reliability.
