Detailed Description

The invention will be further described in the following with reference to specific embodiments thereof, with reference to the accompanying drawings, in which figures 1 to 3:

the utility model provides a pump middle section structure of dredge pump is guided to cutting formula which characterized in that: the water-saving panel comprises a panel 1 and a lower convex ring 2 arranged on the lower surface of the panel 1, wherein the lower convex ring 2 surrounds to form a cavity, a water through hole 3 communicated with the cavity is formed in the center of the panel 1, a guide block 4 integrally connected with the water through hole 3 is arranged at the upper end of the water through hole 3, and a guide surface 5 obliquely arranged is arranged on the guide block 4.

The middle section of the pump has a larger space due to the cavity, and cut objects can be fully dispersed when entering the cavity, so that the cut objects can uniformly enter the impeller 14, and blockage is avoided; the whole guide block 4 is of an arc-shaped structure, the inclination direction of the guide surface 5 is inclined downwards from the top surface of the guide block 4 to the upper end surface of the water passing port, after the middle section of the pump and the pump head 13 are installed, the guide block 4 is positioned in the water inlet ring of the impeller, and the rotating water flow generated when the impeller 14 rotates can quickly enter the impeller 14 along the guide surface 5 of the guide block 4, so that the blocking phenomenon at the position covered with the water passing hole 3 is avoided; in addition, the guide block and the water passing hole are integrally cast and formed, so that the production requirement and the production cost are greatly lower.

Still be equipped with impeller choma recess 6 around crossing the setting of water hole 3 on the upper surface of panel 1, impeller choma recess 6 is used for with impeller choma installation cooperation, to the impeller choma with cross the effect of playing preventing leaking between the water hole 3, improve the lift and the efficiency of pump.

Still be equipped with on the inner wall of water hole 3 and leak husky mouth 7 with impeller mouth ring groove 6 intercommunication, the volume of seting up of leaking husky mouth 7 is less relatively, can be convenient for the interior silt impurity of pump head 13 discharge downwards under the condition that does not influence to leak, avoids producing card husky phenomenon.

An upper convex ring 8 is arranged on the upper surface of the panel 1, a flow guide surface 9 which is obliquely arranged is formed between the inner wall of the upper convex ring 8 and the upper surface of the panel 1, and a pump head 13 of the pump can be clamped with the upper convex ring 8 when being installed with the middle section of the pump, so that the stability is improved; when the impeller 14 rotates, an outward centrifugal water flow is formed on the upper surface of the panel 1, and the sewage and dirt remained on the upper surface of the panel 1 is conveyed into the pump head 13 through the flow guide surface 9.

The periphery of the panel 1 is provided with a plurality of connecting holes 10, and the connecting holes 10 are used for being connected with a pump head 13 of a pump.

The above-mentioned embodiment is only the preferred embodiment of the present invention, and does not limit the protection scope of the present invention according to this, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
