[0002] A low-noise water pump is a water pump device specifically designed to reduce noise during operation. This type of water pump is usually used in applications that require a lower noise level, such as residential areas, commercial buildings, or industrial applications that require a quiet environment. Reducing the vibration of the moving parts inside the water pump can significantly reduce the noise conducted to the surrounding structure. By optimizing the design of the pump and reducing the weight and inertia of the moving parts, the vibration can be effectively reduced. The processing of low-noise water pumps is mainly to ensure the accuracy, quality, and performance of their structures and components.

[0003] For the processing of traditional low-noise water pumps, through precise processing, it can be ensured that the geometric shape, surface finish of the impeller, and the flow channel design of the pump body meet the design specifications, thereby reducing the turbulence and pressure pulsation during fluid movement, and effectively controlling and reducing the noise that may be generated during the operation of the water pump, improving its applicability and performance in a low-noise environment.

A protective component is arranged on the top of the large bottom plate 19. The protective component functions to protect the casting blank 2.

[0033] Specifically, start the second electric push rod 24, drive the fixing tool 25 to move through the second electric push rod 24, fix the casting blank 2, and then start the oil cylinder seat 14. Drive the pressing arm 18 to rotate through the oil cylinder seat 14, and at the same time drive the hinge 15 to rotate through the pressing arm 18, and also fix the casting blank 2. By adopting a high-torque hydraulic clamping unit, the clamping force is made stable and reliable. The body is made of special high-strength and high-wear-resistant materials, realizing a long service life of the fixture.
