As further improvement and supplement to the above technical scheme, the utility model discloses a following technical measure:
in order to improve the applicability of the guide shell, the two guide surfaces are oppositely arranged. The well pump can be suitable for forming water flow rotating clockwise or clockwise in the guide shell during use.
The connecting part of the cylindrical part and the circular ring part is of a step structure (the step angle of the step structure is an arc angle under the normal condition), the overflowing block is fixedly connected (for example, welded) on the step structure, the fixing surface on the overflowing block is in sealing fit with the surface of the step structure, and the axial height of the overflowing block is greater than that of the step structure. Of course, the axial height of the flow-through block can also be adapted to the axial height of the step structure. The axial height of the overflowing block mainly depends on the fact that the overflowing block has a good upward guiding effect on accumulated silt, and the silt can be smoothly discharged.
The overflowing block is provided with a plane, and the plane is parallel to the plane of the circular ring part. Usually, the radial inner end of the flow-through block extends to the radial covering position of the impeller (or extends to the radial projection of the impeller), and the part of the guide block, which is located at the radial covering position of the impeller, is provided with a plane, so that the impeller and the guide block have a proper distance.
The well pump using the guide shell is characterized by comprising a plurality of impeller strings, wherein each impeller string comprises the guide shell, an impeller and a guide vane which are arranged in an inner cavity of the guide shell, the guide vane is arranged at the opening end of the guide shell, and the impeller and the circular ring are matched.
The radial width of the flow-passing block is larger than the maximum radial gap between the impeller and the cylindrical portion. Namely, the radial inner end of the flow passing block extends to the radial covering position of the impeller (or extends to the radial projection of the impeller), and the part of the guide block, which is positioned at the radial covering position of the impeller, is provided with a plane, so that the impeller and the guide block have a proper distance.
The utility model discloses beneficial effect who has: 1. during the use, rivers in the blower inlet casing use the axis as central line circumference rotation flow, set up the excessive flow piece, then rotatory rivers are at the guide effect of water conservancy diversion face, can upwards drain accumulational silt, make silt in time by the water conservancy diversion play, reduce to produce wearing and tearing to the blower inlet casing, improve the life of blower inlet casing, and then improve the normal rate of utilization of well pump, reduce the maintenance rate. 2. In order to improve the applicability of the guide shell, the two guide surfaces are oppositely arranged. 3. The radial inner end of the flow block extends to the radial covering position of the impeller (or extends to the radial projection of the impeller), and the part of the guide block, which is positioned at the radial covering position of the impeller, is provided with a plane, so that the impeller and the guide block have a proper distance. Not only improving the drainage effect on the sediment, but also not influencing the normal use effect of the impeller.

Detailed Description
The technical solution of the present invention is further specifically described below by way of examples and with reference to the accompanying drawings.
Example (b): as shown in fig. 1, the baffle shell includes a cylindrical portion 11 and an annular portion 12, which are integrally formed, and the annular portion 12 is disposed at a bottom end of the cylindrical portion 11. At least one overflowing block 2 is arranged at the connecting part of the cylindrical part 11 and the circular ring part 12, a guide surface 21 is arranged on the overflowing block, and the guide surface 21 is an upward inclined plane. The inclined direction of the flow guide surface is matched with the circumferential direction of the circular ring part. During the use, rivers in the blower inlet casing use the axis as central line circumference rotation flow, set up the excessive flow piece, then rotatory rivers are at the guide effect of water conservancy diversion face, can upwards drain accumulational silt, make silt in time by the water conservancy diversion play, reduce to produce wearing and tearing to the blower inlet casing, improve the life of blower inlet casing, and then improve the normal rate of utilization of well pump, reduce the maintenance rate.
