Description
Technical field:
The utility model relates to mechanical field, is particularly useful for the water pump carrying fluid, the submersible sewage pump of particularly a kind of improvement.
Background technique:
Submersible sewage pump is widely used in municipal engineering field.Owing to often containing foreign material in sewage, the pump housing is easily caused to block.
Summary of the invention:
The purpose of this utility model is the submersible sewage pump providing a kind of improvement, and the submersible sewage pump of described this improvement will to solve in prior art submersible sewage pump easily by the technical problem of foreign material blocking in sewage.
The submersible sewage pump of this improvement of the present utility model, comprise the pump housing, pump shaft and impeller, pump chamber is provided with in the described pump housing, suction port and exhaust port is provided with in the pump housing, described suction port and exhaust port are all communicated with described pump chamber, described pump shaft is arranged in the pump housing by gear mechanism, seal arrangement is provided with between pump shaft and the pump housing, the central axis of pump shaft and the central axes of suction port, described impeller to be fixedly connected on pump shaft and to be positioned at pump chamber, wherein, the pump housing is connected with a cylindrical tube at suction port extenal fixation, described cylindrical tube is coaxial with pump shaft, the bottom of cylindrical tube is provided with opening, or be provided with plurality of through holes in the sidewall of cylindrical tube, the radial cross section area of described opening or the radial cross section area sum of described through hole are greater than or equal to the radial cross section area of suction port, the top and bottom of cylindrical tube are provided with radial struts separately, two cutter shafts are provided with in cylindrical tube, the axis of described cutter shaft is all parallel to the central axis of pump shaft, the top and bottom of any one cutter shaft are all connected with described radial struts each via bearing, the upper end of any one cutter shaft is all connected with the lower end of pump shaft each via gear, any one cutter shaft is provided with plural blade all separately.
Further, the lower end of any one cutter shaft is connected with a conical deflector all separately.
Working principle of the present utility model is: after starting mode of pump, and cutter shaft rotates with pump shaft, and sewage is sucked pump chamber from suction port by impeller, releases from exhaust port.Foreign material in sewage are by the blade cuts on cutter shaft, and volume reduces, and are not easy to block pump chamber.
