Supporting structure of pump shaft locating-free inflow and outflow water body structure

The invention belongs to the technical field of water pump tools, and particularly relates to a supporting structure of a pump shaft locating-free inflow and outflow water body structure. The supporting structure of the pump shaft locating-free inflow and outflow water body structure comprises an inflow water guide blade, a supporting guide blade is arranged above the inflow water guide blade, a main shaft is arranged in the middle of the supporting guide blade, an upper support is disposed at the upper end of the supporting guide blade, a lower support is arranged at the lower end of the supporting guide blade, the supporting guide blade is flat and is positioned at a time, the distance between the upper support and the lower support is shortened, and longitudinal positioning coaxiality is achieved. The supporting structure has the advantages that the coaxiality of a pump shaft can be guaranteed, and fluid amount at a water inlet of a pump is sufficient.
