[0002] The sand suction pump used for sand mining is generally composed of a pump casing, a pump cover, an impeller, a pump shaft and a bearing assembly. The impeller is installed on the shaft head at one end of the pump shaft through the threaded shaft hole in the middle. The sand suction pump has a long working time and a harsh working environment. After use, the combination of the impeller and the pump shaft of the sand suction pump becomes very tight. When the pump needs to be repaired or the impeller needs to be replaced, it is difficult to remove the impeller from the pump shaft. To facilitate the removal of the impeller, a disassembly ring is provided on the existing pump shaft.

[0003] The defects of the existing disassembly ring are:

[0004] Patent document CN202122195574.7 discloses a sand suction pump, "a disassembly ring is provided between the impeller and the shoulder of the pump shaft; the disassembly ring includes an assembly ring and two or more disassembly blocks evenly arranged on its inner circumference; a side of each disassembly block facing the pump shaft is provided with a tile-shaped surface matching the cylindrical surface of the pump shaft, the left and right surfaces of the disassembly block are parallel and perpendicular to the pump shaft, and each disassembly block is provided with at least one disassembly screw hole with an internal thread radially extending from the tile-shaped surface; the assembly ring is provided with a mounting hole corresponding to the disassembly block, and the mounting bolt passes through the mounting hole to fix each disassembly block to the inner side of the assembly ring." However, during the existing disassembly, the pump shaft needs to reserve a demolition height for the equipment ring, so that the equipment ring can be disassembled first and then the demolition block can be disassembled, which increases the production cost of the pump; and when reinstalling the disassembly ring, since the equipment ring is still on the pump shaft, it is more difficult for the maintenance worker to reinstall the demolition block, which increases the difficulty of the work.

[0005] Therefore, in view of the above problems, we need to propose a detachable ring for a pump. Utility Model Content

[0006] The purpose of the utility model is to provide a detachable ring for a pump to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a detachable ring for a pump, comprising an equipment ring, and two or more disassembly blocks evenly arranged on its inner circumference, wherein the equipment ring comprises two equipment half rings, the equipment half rings are semicircular in shape, and connecting protrusions are arranged at both ends of the equipment half rings, and bolt holes are arranged on the connecting protrusions; one or more loading and unloading holes are arranged in the middle part of the equipment half rings, and the number of inclined holes can be increased according to the shaft diameter of the pump to reduce the difficulty of loading and unloading; the two equipment half rings are fixedly connected by the bolt holes at the connecting protrusions; the two equipment half rings are connected end to end to form a ring surrounding the pump shaft.

[0008] Preferably, the surface of the disassembly block facing the pump shaft is arranged as an annular surface matching the cylindrical surface of the pump shaft, and each disassembly block is provided with at least one disassembly screw hole with an internal thread radially penetrating from the annular surface.

[0009] Preferably, the loading and unloading holes provided on the equipment half ring correspond to the positions of the disassembly screw holes of the disassembly block, and the mounting bolts pass through the loading and unloading holes to fix the disassembly block to the inner side of the equipment half ring.

[0010] Preferably, the number of disassembly blocks can increase as the pump shaft diameter increases, which can reduce the difficulty of disassembly.

[0011] Preferably, the equipment half ring is provided with a positioning cavity for the disassembly block, and the positioning cavity is within the loading and unloading hole to facilitate the positioning of the disassembly block and the equipment half ring.

[0012] Preferably, an annular protrusion is provided on the inner upper surface of the disassembly block for supporting various components on the pump and reducing the contact area between the disassembly block and the components during disassembly.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] The utility model fixes the disassembly block by two equipment half rings. When disassembly is required, the connecting bolts of the equipment half rings can be removed and the equipment half rings can be directly removed, thereby saving the reserved height of the pump shaft in the original product and further reducing the production cost of the pump.

[0015] The utility model can arrange two or more disassembly blocks on the inner circumference of the equipment ring according to the diameter of the pump shaft, which can reduce the difficulty of the operator during disassembly and improve the maintenance efficiency.
