Problems solved by technology

At present, with the continuous development of science and technology, the axial flow pump has made great progress in technology, but there are also the following technical problems that urgently need to be improved: (1) The axial movement of the pump shaft is relatively large when the axial flow pump is started. (2) During the operation of the axial flow pump, sometimes there will be vibration and noise, which will reduce the sealing performance of the axial flow pump for a long time, and increase the packing and rubber bearing at the same time. Wear and tear, reducing the service life of the axial flow pump

Abstract

The invention provides a novel axial flow pump. The novel axial flow pump comprises an axial flow pump body and a seal assembly, wherein the axial flow pump body comprises a shell and a pump shaft; aguide pipe communicating with the interior of the shell is arranged on the top of the shell; an annular supporting part is arranged on the inner wall of the top end of the guide pipe; a rubber bearingmatched with the pump shaft is arranged in the guide pipe; the pump shaft comprises a shaft shoulder supported against the bottom end of the rubber bearing; the seal assembly comprises a first elastic adjusting part and a second elastic adjusting part; the first elastic adjusting part is arranged on the pump shaft in a sleeving manner and is located between the supporting part and the rubber bearing; the second elastic adjusting part is arranged on the rubber bearing in a sleeving manner and is located below the first elastic adjusting part; a buffer layer which is arranged on the rubber bearing in a sleeving and sealing manner is arranged between the first elastic adjusting part and the second elastic adjusting part; a containing cavity for placing filler is formed by the first elastic adjusting part, the buffer layer, the rubber bearing and the pump shaft in a surrounding manner; and wedge-shaped sealing rings are pressed between the first elastic adjusting part and the supporting part and between the second elastic adjusting part and the shaft shoulder. The novel axial flow pump has relatively good sealing property and cooling effect.

Description

technical field [0001] The invention relates to the field of axial flow pumps, in particular to a novel axial flow pump. Background technique [0002] The axial flow pump uses the thrust generated by the high-speed rotation of the impeller to lift water, push the water from the bottom to the top, and realize the transportation of water. At present, with the continuous development of science and technology, the axial flow pump has made great progress in technology, but there are also the following technical problems that urgently need to be improved: (1) The axial movement of the pump shaft is relatively large when the axial flow pump is started. (2) During the operation of the axial flow pump, sometimes there will be vibration and noise, which will reduce the sealing performance of the axial flow pump for a long time, and increase the packing and rubber bearing at the same time. The wear and tear will reduce the service life of the axial flow pump. Contents of the inventi...
