Abstract
The invention belongs to the technical field of water pump tools, and particularly relates to a pump shaft position-changeable water incoming and outgoing body structure which comprises a water pump water incoming and outgoing body, a first stop port and a second stop port are formed in the upper end face of the water pump water incoming and outgoing body, a water incoming guide vane is matched with the first stop port, a supporting guide vane is arranged above the water incoming guide vane, a spindle is arranged in the middle of the supporting guide vane, an upper support is arranged at the upper end of the supporting guide vane, a lower support is arranged at the lower end of the supporting guide vane, the supporting guide vane is flat for one-time positioning, reduces distance between the upper support and the lower support and realizes coaxiality of up-down positioning, an outer barrel matched with the second stop port is connected at the second stop port, and the water incoming guide vane is arranged in the outer barrel. The pump shaft position-changeable incoming and outgoing water body structure has the advantages that pump shaft coaxiality can be ensured, and sufficient fluid quantity and water incoming flow smoothness at a pump water inlet can be realized.
Description
Technical field
The invention belongs to water pump apparatus technical field, particularly relate to a kind of pump shaft without location water inlet and outlet body structure.
Background technique
In existing stainless steel multistage centrifugal pump, its turnover water body center is provided with pump shaft fixed structure, its deficiency: add positioning bearing because turnover water body center is provided with mounted pump axle construction, compromise the proper flow of current, have a strong impact on the smooth and easy technical requirements of Pump Suction Nozzle fluid, and the flow velocity between internal impeller creates inconsistent phenomenon, thus the efficiency of the whole pump of impact.And there is boss in the inlet of turnover water body, and make into water liquid stream not enough smoothly.
Summary of the invention
The object of the invention is to solve above-described technical problem, provide one can guarantee pump shaft coaxality, pump water inlet mouth can be made again to have the adequate flow scale of construction, pump shaft is without location water inlet and outlet body structure smoothly for liquid stream of intaking, its technological scheme is as follows:
Pump shaft is without location water inlet and outlet body structure, it is characterized in that, described pump shaft comprises water pump turnover water body without location water inlet and outlet body structure, the upper-end surface of described water pump turnover water body offers the first seam and the second seam, and the first described seam and the second seam simultaneously disposable clamping process; The top place of the first seam is provided with into water stator, water inlet stator and the first seam match, the top place of water inlet stator is provided with support guide vane, the middle of support guide vane is provided with main shaft, the upper end of support guide vane is provided with support, and the lower end of support guide vane is provided with lower support, and support guide vane is flat-shapedly do disposable location, distance in shortening between support and lower support, realizes the coaxality of locating up and down; Second stop portion is connected with the urceolus matched with it, and water inlet stator is arranged in urceolus.
Optimal way is, described main shaft is arranged at the middle of support guide vane by positioning device, and positioning device comprises positioning block and stable block, and positioning block is positioned at for connecting main shaft and support guide vane in lower support, and stable block is located at above positioning block and is located.
Optimal way is, the middle of described water pump turnover water body is provided with smooth arc plate.
Pump shaft provided by the invention is without location water inlet and outlet body structure, and when in use, the first seam and the second seam simultaneously disposable clamping process, and ensure that the coaxality of pump shaft, also ensure that the normal work of pump.Water inlet stator, support guide vane, urceolus be arranged so that the coaxality that ensure that pump shaft.
The middle of the water pump turnover water body that the present invention is further described is provided with smooth arc plate.Boss is removed, makes it the smooth transition by smooth arc plate, and make into water liquid stream smooth and easy.
The further optimal way of the present invention is, described main shaft is arranged at the middle of support guide vane by positioning device, positioning device comprises positioning block and stable block, and setting sleeve is positioned at for connecting main shaft and support guide vane in lower support, and stable block is located at above setting sleeve and is located.Make main shaft can be more stable, better guarantee the coaxality of pump shaft simultaneously.
The invention has the beneficial effects as follows: pump shaft coaxality can be guaranteed, pump water inlet mouth can be made again to have the adequate flow scale of construction, water inlet liquid stream smooth and easy.
