Description

Technical Field

[0001] The utility model relates to the technical field of volutes, in particular to a volute which is convenient for disassembly and maintenance. Background Art

[0002] The volute is the abbreviation of the volute-type water diversion chamber. Its appearance is very similar to a snail shell, so it is usually referred to as the volute. In order to ensure uniform water supply to the water guide mechanism, the cross-section of the volute is gradually reduced. At the same time, it can form a necessary ring in front of the water guide mechanism to reduce the working intensity of the water guide mechanism. There is a patent for a volute, and the patent publication number is CN216950985U, which includes: a volute body, the volute body includes a water pressure chamber and an outlet pipe, the outlet pipe is arranged along the axial direction of the water pressure chamber and is connected to the water pressure chamber; a guide piece is provided at the connection between the water pressure chamber and the inside of the outlet pipe; the principle and effect of this scheme: when the volute cooperates with the impeller to pump water, the impeller sucks water into the water pressure chamber, and the rotation of the impeller drives the water in the water pressure chamber to flow out from the outlet pipe to achieve water pumping. Compared with the traditional radial setting of the outlet pipe, the axial setting of the outlet pipe can reduce the radial size of the volute and the overall size of the water pump. At the same time, the guide member in the present application can reduce the resistance of water from the water pressure chamber to the outlet pipe, thereby increasing the amount of water extracted. Furthermore, the guide member is a baffle tongue, which is inclined to the axial line of the volute body. Beneficial effect: in the prior art, since the baffle tongue of the volute is parallel to the axial line, each rotation of the blades on the impeller will bring water from the water pressure chamber to the outlet pipe, and each rotation will drive the water to collide with the baffle tongue, which has a greater resistance to water. At the same time, the water pumped out by the water pump will be reduced, and the water pump will generate greater vibration and noise during the pumping process. By setting the baffle tongue at an angle, the resistance to water is reduced, the water flow is better guided, and the vibration and noise generated by the water pump during pumping are reduced.

[0003] Regarding the above-mentioned related technologies, the inventor believes that the following defects exist: although the equipment will not be damaged by rust, in actual practical use, the vibration and noise generated by the water pump when pumping water are reduced. The existing volute is mostly fixed by nuts and bolts at the four corners, which is inconvenient to fix and disassemble, and the volute installation direction only has four directions. When the position needs to be adjusted, the position needs to be adjusted as a whole. Therefore, we propose a volute that is easy to disassemble and maintain to solve the above-mentioned problems.
