Abstract
The utility model relates to a submersible sewage pump, comprising a pump body and an impeller, wherein the impeller is driven by a motor; a bearing is arranged between the shaft of the motor and the pump body; an inner groove is formed in a hole for assembling the bearing; an elastic retainer ring for the hole is mounted in the inner groove; the retainer ring is mounted on the upper part of the outer ring of the bearing to ensure that the outer ring of the bearing cannot drift upwards; and a positioning lug boss is fixed at the lower part of the outer ring of the bearing to ensure that the outer ring of the bearing cannot drift downwards. The submersible sewage pump is characterized in that the bearing is positioned in upward and downward two directions, and therefore, up and down drifting of the bearing is effectively prevented.
Description
Technical field
The utility model relates to a kind of proof submersible sand discharging pump.
Background technique
Proof submersible sand discharging pump is due to part processing and assembly error, and the unequal reasons that waits of water pump vane front and rear covers axially loaded area all can make water pump produce axial force, and the direction of this axial force changes because pump operating condition is different.So guarantee that the above-below direction of bearing all will have the device that prevents reliably play.Existing proof submersible sand discharging pump is more does not have the upper and lower play of Control Shaft bearing outer-ring, has greatly affected the working life of proof submersible sand discharging pump.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned defect of prior art, and a kind of proof submersible sand discharging pump that effectively prevents the upper and lower play of bearing outer ring is provided, and guarantees bearing outer ring play downwards, quality and the life-span of effectively improving proof submersible sand discharging pump.
The utility model comprises the pump housing, impeller, impeller is driven by motor, between motor shaft and the pump housing, be provided with bearing, its technical solution is: in running in bearings hole, process an internal channel, circlip for hole is installed in internal channel, the bearing outer ring play that can not make progress is guaranteed on the top that back-up ring is arranged on bearing outer ring, and the bottom of bearing outer ring arranges stationary positioned boss, guarantees bearing outer ring play downwards.
Said structure positions bearing from upper and lower both direction, has effectively prevented the play up and down of bearing.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, further illustrate particular content of the present utility model.
Fig. 1: the structural representation of the present embodiment.
The partial enlarged drawing of Fig. 2: Fig. 1.
Embodiment
As shown in the figure, the present embodiment comprises the pump housing 1, impeller 5, impeller 5 is driven by motor 2, between motor shaft 6 and the pump housing 1, be provided with bearing 4, in running in bearings hole, process an internal channel, circlip for hole 8 is installed in internal channel, the bearing outer ring play that can not make progress is guaranteed on the top that back-up ring 8 is arranged on bearing 4 outer rings, the bottom of bearing outer ring arranges stationary positioned boss 9, guarantees bearing outer ring play downwards.
