Axial flow pump capable of controlling waterflow velocity

Abstract

The invention discloses an axial flow pump capable of controlling waterflow velocity. The axial flow pump comprises a motor, a flow guiding vane and a bearing, wherein a first rotating shaft is fixedly connected to the left side of the motor and is connected with a second rotating shaft through a bolt; the second rotating shaft sequentially penetrates through a sealing block, a sealing gap, the bearing, the flow guiding vane and an impeller from right to left; a sealing support is welded to the left side of the sealing block; a pump body is welded to the left side of the sealing support; the sealing gap is formed in the sealing support; a pump body is welded to the left side of the sealing gap; a connecting support is welded to the two sides of the bearing; the upper end of the connectingsupport is welded to the inner wall of the pump body; and a support is welded to the left side of the outer wall of the pump body. According to the axial flow pump capable of controlling the waterflowvelocity disclosed by the invention, through rotation of a rotary disc, a sealing plate is moved up or down through threads, so that an opening of the pump is changed, the waterflow velocity is changed, water resources slowly flow into a field, and conservation of the water resources is realized.

Description

technical field [0001] The invention relates to the technical field of axial flow pumps, in particular to an axial flow pump capable of controlling water flow velocity. Background technique [0002] Axial flow pumps have now become a commonly used water pumping tool. Axial flow pumps can be used to pump accumulated water and irrigate farmland, and the current axial flow pumps have problems due to the fact that the pump port cannot be adjusted in size when irrigation is performed. The pump cannot control the water flow rate, so that in the process of irrigation, the water in the farmland often exceeds the required water range, resulting in a waste of water resources. Contents of the invention [0003] The object of the present invention is to provide an axial flow pump capable of controlling the water flow velocity, so as to solve the problem of inability to control the water flow velocity presented in the above-mentioned background technology. [0004] In order to achieve...
