Abstract
The utility model belongs to the technical field of the water pump apparatus, especially, relate to a pump shaft does not have location and advances water -out body structure. The utility model discloses a pump shaft does not have location and advances water -out body structure, pump shaft does not have location and advances water -out body structure include that the water pump advances water -out body, the water pump advance to have seted up first tang and second tang on water -out body's the up end, the simultaneously disposable clamping processing of first tang and second tang form, support the stator and be the disposable location of flat form work, shorten to go up and support and under bracing distance within a definite time, the axiality of location about realizing, even there is assorted urceolus with it in second tang department, and the stator of intaking sets up in the urceolus. The beneficial effects of the utility model are that: can ensure the pump shaft axiality, can make the pump water inlet have sufficient fluid volume, the liquid stream of intaking smooth and easy again.
Description
Technical field
The utility model belongs to water pump apparatus technical field, particularly relates 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 purpose of this utility model is to solve above-described technical problem, provides one can guarantee pump shaft coaxality, and 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.
The pump shaft that the utility model provides 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 utility model 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 utility model 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 beneficial effects of the utility model are: can guarantee pump shaft coaxality, and pump water inlet mouth can be made again to have the adequate flow scale of construction, water inlet liquid stream smooth and easy.
