Reverse double-turbine high-pressure axial flow pump

Abstract

The invention discloses a reverse double-turbine high-pressure axial flow pump, and relates to the technical field of axial flow pumps. The reverse double-turbine high-pressure axial flow pump comprises a water conveying pipe, two rotary bearings with same structures are arranged at the positions, close to the upper position and the lower position, of an inner cavity of the water conveying pipe, and turbofans are arranged on the inner walls of every two rotary bearings. A sealing shell is arranged on the right side of the water conveying pipe, a motor is arranged on the right side of the waterconveying pipe, a rotary shaft is arranged in an inner cavity of the motor, the rotary shaft penetrates through the surface of the motor, an upper gear is arranged at the bottom of the rotary shaft,a lower gear is arranged at the bottom of the rotary shaft, and the surface of the upper gear is clamped with the surface of the turbofan at the upper end. Two installation blocks with same structuresare arranged on the right side of the water conveying pipe, a rotating shaft is arranged between the two installation blocks with the same structures, a transmission gear is arranged on the surface of the rotating shaft, and the left side of the transmission gear is clamped with surface of the turbofan at the lower end. According to the reverse double-turbine high-pressure axial flow pump, the resistance of the flow is reduced, no gap exists between the turbofans and the inner wall of the water conveying pipe, the loss of pressure is avoided, and the efficiency of a water pump is improved.

Description

technical field [0001] The invention relates to the technical field of axial flow pumps, in particular to a reverse twin-turbine high-pressure axial flow pump. Background technique [0002] Axial flow pump is a common type of water pump at present. Due to the strong conveying capacity of the axial flow pump, the fluid is led to the outlet by the lift of the blades. It is axially in and axially out, and has the advantages of large flow. Forming an integrated body, there is no need for labor-intensive and time-consuming assembly processes of the motor, transmission mechanism, and water pump axis alignment at the installation site. The on-site installation is convenient and fast. Outside the pipe, however, this kind of playing pipe will increase the resistance of the water flow and slow down the speed of the water flow, and the gap between the turbofan and the inner wall of the pipe is large, which is easy to cause pressure loss, thereby reducing the efficiency of the water pum...
