Description

Technical Field

[0001] The utility model relates to the technical field of impellers, in particular to a high-speed and stable three-dimensional flow impeller. Background Art

[0002] A water pump is a machine for conveying liquid or pressurizing liquid. The impeller is the core component of a vane pump. A three-dimensional flow impeller is a relatively advanced impeller. Its basic principle is that the three-dimensional flow theory of the jet wake is continuously and infinitely divided in the three-dimensional space inside the impeller to establish a complete dynamic model. This model is more efficient, reduces energy loss during flow, and makes the water pump more efficient. However, the blades of the three-dimensional flow impeller are directly fixed to the surface of the impeller body. When the three-dimensional flow impeller works normally, the blades are in direct contact with the fluid, and the fluid repeatedly impacts the blades, making it easy for the blades to loosen from the impeller body, causing the blades to fall off. For example, a Chinese patent discloses "three-dimensional flow impeller and water pump", and its application number is: "202320878578. 1", which is passed through the disc body through the first end of the blade. When the three-dimensional flow impeller works normally, the blade is in continuous contact with the fluid. When the fluid impacts the blade, the blade transmits the impact force to the disc body through the first end, avoiding the impact force of the fluid directly impacting the connection structure between the disc body and the blade, thereby making the connection between the blade and the disc body more firm and reliable, avoiding the technical problem in the prior art that the blades of the three-dimensional flow impeller are directly fixed to the surface of the disc body, making it easy for the blades to loosen from the disc body, or even causing the blades to fall off. However, during the rotation of the device and the repeated impact of the fluid on the blades, the impeller and the disc may shake, causing pump failure and affecting the use of the water pump.
