[0002] A vertical mixed flow pump is a mixed flow pump placed vertically. A mixed flow pump is a type of pump between a centrifugal pump and an axial flow pump. The specific speed of a mixed flow pump is higher than that of a centrifugal pump and lower than that of an axial flow pump, generally between 300 and 500. Its head is higher than that of an axial flow pump, but its flow rate is smaller than that of an axial flow pump and larger than that of a centrifugal pump.

[0003] However, the existing vertical long-axis mixed flow pump has the following problems:

[0004] The pump body and motor of the vertical long-axis mixed-flow pump are difficult to disassemble and separate quickly, which makes the maintenance of the pump body and the motor more troublesome.

[0005] Therefore, we made improvements on this and proposed a vertical long-axis mixed-flow pump with a separated pump body and motor. Utility Model Content
