Abstract
The utility model relates to a novel dive axial-flow pump pit shaft, including the pit shaft, its characterized in that: the shaft is composed of an upper section of cylinder body and a lower section of cylinder body, a flange ring is arranged at the bottom of the upper section of cylinder body, a flange ring is arranged at the top of the lower section of cylinder body, the two flange rings are connected through a flange bolt, and a rubber sealing gasket is arranged on the contact surface of the two flange rings. The inner wall of the cylinder body at the lower part of the lower section of the cylinder body is welded with an anti-rotation block, a seat ring and a support rib which correspond to the axial-flow pump. The length of the upper section of the upper and lower sections of the cylinder body is greater than that of the lower section of the cylinder body. The utility model has the advantages that divide into a section of long barrel and a section of short barrel with original very long pit shaft, the dive axial-flow pump mounting dimension of short barrel and different operating modes is supporting. When the submersible axial-flow pump needs to be replaced, only the section cylinder body needs to be replaced, the whole shaft does not need to be replaced, economic benefits are achieved, and materials are saved.
Description
Technical Field
The utility model relates to an axial-flow pump pit shaft, especially a novel dive axial-flow pump pit shaft.
Background
The submersible axial-flow pump motor and the water pump are integrated, the submersible axial-flow pump motor and the water pump are hung into a special shaft during installation, and a seat ring of the shaft is installed with the water pump in a coupling mode. The pumps with the same caliber need to be provided with special shafts under different working conditions, and shafts 21 (in figure 1) matched with submersible axial flow pumps 20 (in figure 1) of various water pump manufacturers are different. After long-time operation, because the field working condition changes or the service life of the water pump is finished, the old pump needs to be modified or the pump types of different manufacturers need to be replaced, the original submersible axial-flow pump and the matched shaft are completely replaced, so that the shaft waste is caused, and therefore the improvement of the shaft of the existing axial-flow pump is urgently needed to reduce the cost.
Disclosure of Invention
The utility model aims at solving prior art axial-flow pump pit shaft and need change and abandon the above-mentioned problem that exists along with the axial-flow pump, provide a novel dive axial-flow pump pit shaft. The utility model relates to a novel dive axial-flow pump pit shaft, including the pit shaft, its characterized in that: the shaft is composed of an upper section of cylinder body and a lower section of cylinder body, a flange ring is arranged at the bottom of the upper section of cylinder body, a flange ring is arranged at the top of the lower section of cylinder body, the two flange rings are connected through a flange bolt, and a rubber sealing gasket is arranged on the contact surface of the two flange rings. The inner wall of the cylinder body at the lower part of the lower section of the cylinder body is welded with an anti-rotation block, a seat ring and a support rib which correspond to the axial-flow pump. The length of the upper section of the upper and lower sections of the cylinder body is greater than that of the lower section of the cylinder body. The utility model has the advantages that divide into a section of long barrel and a section of short barrel with original very long pit shaft, the dive axial-flow pump mounting dimension of short barrel and different operating modes is supporting. When the submersible axial-flow pump needs to be replaced, only the section cylinder body needs to be replaced, the whole shaft does not need to be replaced, economic benefits are achieved, and materials are saved.

Detailed Description
In the figure, a novel submersible axial-flow pump shaft comprises a shaft body and is characterized in that: the shaft is composed of an upper section of cylinder body and a lower section of cylinder body, a flange ring 2 is arranged at the bottom of the upper section of cylinder body 1, a flange ring 4 is arranged at the top of the lower section of cylinder body 3, the two flange rings are connected through a flange bolt 5, and a rubber sealing gasket 6 is arranged on the contact surface of the two flange rings. The inner wall of the cylinder body at the lower part of the lower section of the cylinder body is welded with an anti-rotation block 8, a seat ring 9 and a support rib 10 which correspond to the axial-flow pump 7. The length of the upper section of the upper and lower sections of the cylinder body is greater than that of the lower section of the cylinder body.
When the submersible axial flow pump is actually used, an original long shaft is divided into a section of long cylinder (an upper section of cylinder) and a section of short cylinder, and the short cylinder (a lower section of cylinder) is matched with submersible axial flow pumps under different working conditions in installation size. When the submersible axial-flow pump needs to be replaced, only one section of short cylinder needs to be replaced, the whole shaft does not need to be replaced, economic benefits are achieved, and materials are saved.
