Abstract
The utility model discloses a no blocking well diving pump, designed for the problem of the blocking caused by depositing of mud flowed over the prior well diving pump sprue and the flow guiding shell. The no blocking well diving pump of the utility model comprises a pump body which is fixedly equipped with a flow guiding shell and a pump cover, wherein a blade wheel is arranged in the inner cavity between the flow guiding shell and the pump cover, and the blade wheel has the shape of conical sprue twisted blade, also the flow guiding shell has the shape of spacing conical sprue twisted blade. When the mud deposits, the mud will automatically slide out of the sprue for the sprue shape is conical, thereby solving the familiar lacunas of abnormal operating of pump sprue caused by mud depositing and blocking.
Description
Technical field
The utility model patent relates to the well submersible pump, especially a kind of non blocking type well submersible pump.
Background technique
In the prior art, well commonly used includes pump housing part with submersible pump.Be provided with impeller, blower inlet casing and pump cover in its pump housing, pump shaft is located in the blower inlet casing.Inner chamber between blower inlet casing and the pump cover is provided with impeller, and the impeller of the pump housing, blower inlet casing all adopt the plane front and back guide blade, because impeller channel is a plane shape, silt deposits its water passage surface easily, and the time is long more, deposits thick more, cause runner to stop up, flow reduces, even can not water outlet.
The model utility content
In order to overcome above-mentioned defective, the purpose of this utility model is to provide a kind of well submersible pump that prevents that the sedimentation of pump runner from stopping up.
For solving the problems of the technologies described above, the utility model non blocking type well comprises pump housing part with submersible pump, be set with blower inlet casing and pump cover on the pump housing, inner chamber between blower inlet casing and the pump cover is provided with impeller, described impeller shape is the tapered runner twisted blade, and blower inlet casing is a space tapered runner twisted blade.
After adopting such structure, because the runner of impeller and blower inlet casing is taper, when sedimentation, silt can skid off runner along the inclined-plane of taper automatically, thus the use defective that has solved the pump runner and can not normally move because sedimentation is stopped up.
Description of drawings
Fig. 1 is the cross-sectional schematic of the utility model non blocking type well with submersible pump.
Embodiment
The utility model non blocking type well shown in Figure 1 includes the pump housing 20 with submersible pump, be set with blower inlet casing 1 and pump cover 19 on the pump housing, the inner chamber that blower inlet casing 1 and pump cover are 19 is provided with impeller 2, described impeller 2 is shaped as the tapered runner twisted blade, and blower inlet casing 1 is a space tapered runner twisted blade.
When sedimentation, because the runner of impeller 2 and blower inlet casing 1 is taper, silt can skid off runner along the inclined-plane of taper automatically, thus the use defective that has solved the pump runner and can not normally move because sedimentation is stopped up.
Claims (1)
1, a kind of non blocking type well submersible pump, described submersible pump comprises the pump housing, be set with blower inlet casing and pump cover on the pump housing, inner chamber between blower inlet casing and the pump cover is provided with impeller, it is characterized in that: described impeller shape is the tapered runner twisted blade, and blower inlet casing is a space tapered runner twisted blade.
