Embodiment

[0011] Such as Figure 1 ~ Figure 2 Shown, the present invention is the power of motor by power cable (6), and signal cable (7), impeller (1), pump cover (2), pump body (10), base (11) and motor, motor mainly consists of The rotor (3) and the stator (4), the motor transmits torque to the impeller (1) through the pump shaft (8), the bearings (5, 9) support and fix the pump shaft (8), and the outlet of the pump body (10) is Multiple export forms. When the pump is working, the liquid pumped by the impeller (1) flows out through multiple outlets of the pump body (10). The lower ends of the outlets are horizontal, so that the water pump can be installed in the wellbore stably, and then reach the designated position through the wellbore.

Abstract

The invention relates to a multi-outlet subduction-typed pump. The outlet of the pump is designed into a multi-outlet form, thereby playing the role of replacing an exit guide vane and improving the efficiency of the pump; moreover, the height of the pump is slightly lower than the height of the same pump with the guide vane.

Description

Technical field: [0001] The present invention relates to fluid machines. Specifically refers to a submersible pump with multiple outlets, using multiple outlets instead of outlet guide vanes. Background technique: [0002] In the past, when designing submersible axial flow pumps, guide vanes are usually installed at the outlet of the impeller. The function of the guide vanes is to change the rotation of the water flowing out of the impeller into axial movement, and at the same time convert part of the kinetic energy into pressure energy. In order to minimize the hydraulic loss at the pump outlet, there is an optimal swirl flow. The shape and installation angle of the set guide vane are very difficult to make the outlet water flow reach the optimal swirl flow, so that the efficiency of the pump cannot reach the maximum. Invention content: [0003] In order to solve the above problems, the purpose of the present invention is to provide a submersible pump with multiple outl...
