Description

Technical Field

[0001] The utility model belongs to the technical field of a flow guide shell, and relates to a flow guide shell, in particular to a novel flow guide shell. Background Art

[0002] At present, vertical multi-stage pumps are used more and more widely, and are applied to the circulating pressurization of cold and hot clear water in high-pressure operation systems, the parallel water supply of multiple pumps in high-rise buildings, fire fighting, boiler feed water, cooling water systems, and the transportation of various flushing liquids.

[0003] According to the search on the patent website, the application number is CN208057516, and the patent name is a flow guide shell for a vertical multi-stage pump. It discloses a flow guide shell for a vertical multi-stage pump, including a flow guide shell body. The flow guide shell body is made of carbon steel, and the surface of the flow guide shell body is treated by electrophoresis. An upper shell and a lower shell are arranged on the flow guide shell body. An inlet is formed between the upper shell and the lower shell. The upper shell includes flow guide fan-shaped ribs and a cover plate. The upper surface of the flow guide fan-shaped ribs is fixedly welded corresponding to the cover plate, and the lower surface of the flow guide fan-shaped ribs is closely welded to the upper shell. The distribution positions between the flow guide fan-shaped ribs are equidistant from the central axis of the upper shell, and the bending directions of the flow guide fan-shaped ribs are arranged clockwise. The flow guide fan-shaped ribs provided by this flow guide shell can effectively improve the flow guide performance in the pump. However, after long-term use, the flow guide fan-shaped ribs will be worn, resulting in a poor use effect in the later stage. Moreover, the flow guide fan-shaped ribs and the flow guide shell are welded, so they cannot be replaced later and can only be replaced as a whole, increasing the use cost.

[0004] Most of the existing flow guide shells and flow guide fan-shaped ribs are integrally arranged or fixed by welding. After long-term use, the flow guide fan-shaped ribs are worn, resulting in a poor use effect and the inability to replace the flow guide fan-shaped ribs, so only the whole can be replaced, increasing the use cost. Summary of the Invention

[0005] The purpose of the utility model is to provide a novel flow guide shell that is convenient for replacement and maintenance in view of the above problems existing in the prior art.

[0006] The purpose of the utility model can be achieved by the following technical solutions: A novel flow guide shell, including a flow guide shell body, characterized in that a flow guide device is arranged on the flow guide shell body. The flow guide device is composed of an installation part and a plurality of flow guide fan-shaped ribs. A connecting column is arranged on the installation part. A connecting hole matching with the connecting column is opened on the flow guide shell body. A clamping device is arranged on the connecting column. An installation groove for installing the clamping device is opened in the connecting column. The clamping device is composed of a pressing spring and a clamping block.

[0007] In the above-mentioned new type of flow guide shell, a number of limiting posts for limiting are provided on the flow guide shell, and a number of limiting holes matching the limiting posts are provided on the installation part.

[0008] In the above-mentioned new type of flow guide shell, a limiting part is provided on the clamping block.

[0009] Compared with the prior art, the utility model can make the flow guide device be quickly disassembled and replaced through the cooperation of the clamping device on the connecting column and the connecting hole, and the cooperation of the limiting post and the limiting hole increases the radial connection strength between the flow guide shell and the flow guide device, avoiding the damage of the connecting column.
