The utility model has the advantages that: 1) the volume from the pump shell suction port to the pump shell outlet cavity is gradually increased; 2) the appearance profile is designed based on an Archimedes spiral line, so that the angular speed is consistent when liquid passes through the liquid, and the influence of turbulent flow when the liquid flows is avoided; 3) the outer diameter of the pump shell adapter cover is larger than that of the internally installed blades, so that the assembly characteristic of the stirring and sucking pump body can be improved.
Description
Technical Field
The utility model relates to a novel stir and inhale the pump body, concretely relates to novel stir and inhale the pump body suitable for clear away bottom silt in operation waters belongs to dredging pump technical field.
Background
The dredging pump (stirring suction pump/dredging pump) is a component on a special engineering carrier vehicle and plays a role in dredging.
When the desilting pump in the prior art is used for desilting operation, silt directly enters a pump shell through a silt inlet, and harder substances or insoluble substances in the silt easily cause the pump body to be blocked, so that the normal operation of the pump body is influenced, and the pump body can be damaged in serious conditions. And most of the sludge on the river bottom surface is removed by motor driving.
SUMMERY OF THE UTILITY MODEL
The utility model provides a novel stir and inhale the pump body, its purpose aims at overcoming the above-mentioned defect that prior art exists, increases pump body silt through the high flux pump case and passes through the rate.
The technical solution of the utility model is as follows: the utility model provides a novel stir and inhale pump body, its structure includes pump case main part and connects pump case switching lid and the reducing booster pipe at pump case main part both ends respectively, and reducing booster pipe tip is the pump case suction inlet, and pump case main part middle part intercommunication pump case export, the inside pump case inner chamber that is of pump case main part, the pump case inner chamber is the volute form.
Preferably, the reducing pressurizing pipe is of a conical gradual change inner shape and is connected with the bottom of the pump shell main body through a bolt.
Preferably, the outline of the inner cavity of the pump shell is gradually increased in an Archimedes spiral line shape.
Preferably, the outer diameter of the pump shell adapter cover is larger than the outer diameter of the blades arranged in the pump shell inner cavity.
The utility model has the advantages that: 1) the volume from the pump shell suction port to the pump shell outlet cavity is gradually increased;
2) the appearance profile is designed based on an Archimedes spiral line, so that the angular speed is consistent when liquid passes through the liquid, and the influence of turbulent flow when the liquid flows is avoided;
3) the outer diameter of the pump shell adapter cover is larger than that of the internally installed blades, so that the assembly characteristic of the stirring and sucking pump body can be improved.

Detailed Description
The present invention will be described in further detail with reference to examples and specific embodiments.
As shown in figures 1-4, the novel stirring and sucking pump body structurally comprises a pump shell main body 2, a pump shell switching cover 3 and a reducing pressure pipe 1, wherein the pump shell switching cover 3 and the reducing pressure pipe 1 are respectively connected with two ends of the pump shell main body 2, a pump shell suction port 2-1 is arranged at the end part of the reducing pressure pipe 1, a pump shell outlet 2-3 is communicated with the middle part of the pump shell main body 2, a pump shell inner cavity 2-2 is arranged inside the pump shell main body 2, and the pump shell inner cavity 2-2 is in a volute shape.
The volute-like pump casing cavity 2-2 can increase the pressure and reduce the speed of water flowing through the system. The structure of the reducing pressurizing pipe 1 can realize the steep increase of the liquid pressure input into the pump body and realize high-efficiency output.
The volute-shaped pump shell inner cavity 2-2 realizes the characteristic that the cavity volume gradually increases from the pump shell suction port 2-1 to the pump shell outlet 2-3 when the blades are assembled in the pump shell main body 2.
The reducing booster pipe 1 is in a conical gradual change inner shape and is connected with the bottom of the pump shell main body 2 through a bolt.
The inner cavity 2-2 of the pump shell gradually increases: the appearance profile is based on the design of Archimedes spiral, guarantees that the angular velocity is unanimous when liquid passes through, avoids the vortex influence when liquid flows.
The outer diameter of the pump shell adapter cover 3 is larger than that of the blades arranged in the pump shell inner cavity 2-2, so that the assembly characteristic of the stirring and sucking pump body can be improved.
All the above components are prior art, and those skilled in the art can use any model and existing design that can implement their corresponding functions.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many modifications and improvements can be made without departing from the inventive concept, and all of them belong to the protection scope of the present invention.
