Description

Technical Field

[0001] The utility model relates to the technical field of water pump impellers, in particular to an impeller capable of reducing pressure pulsation. Background Art

[0002] Water pumps are widely used in daily life and industrial production. In the existing water pump impeller, centrifugal water pumps are usually used, that is, cooling water enters from the axial direction of the water pump impeller and is discharged from the side of the water pump impeller. The impeller is an indispensable part of the water pump. For example, a water pump impeller proposed in the prior art publication number CN205446172U includes multiple blades distributed radially, characterized in that at least one water retaining ring extends along the axial direction of the water pump impeller. However, when the water pump is working, the impeller is always in high-speed operation. When running, the impeller rotates at high speed with the coolant. The rotation will cause large pressure pulsation due to the inconsistent linear speed of each area of ​​the impeller, causing the impeller to move up and down, thereby greatly increasing the noise and vibration of the entire water pump. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides an impeller for reducing pressure pulsation, which can reduce the pressure pulsation of a water pump, and reduce the noise and vibration of the water pump.

[0004] The utility model discloses an impeller for reducing pressure pulsation, comprising a connecting seat, a fixing disk fixedly mounted on one end of the connecting seat, a plurality of blades evenly arranged and mounted on the fixing disk, a cover disk connected to the other end of the blade, and cutting blades mounted on the plurality of blades; when in use, a motor drives the connecting seat to rotate, and the connecting seat drives the fixing disk and the blades to rotate, and the cutting blades can first cut the fluid to reduce the pressure pulsation of the fluid, and after the pressure pulsation of the fluid is reduced, the blades throw the fluid out, thereby achieving the purpose of reducing the noise and vibration of the water pump.

[0005] Preferably, the cutting blade is configured in a shark fin shape, which gradually expands from the outside to the inside and is completely matched with the blade; when rotating, the cutting blade cuts the fluid to reduce the pressure pulsation of the fluid, and the shark fin-shaped cutting blade can improve the cutting effect on the fluid.

[0006] Preferably, a circular hole is provided in the middle of the connecting seat, and a plurality of mounting holes are provided at one end of the connecting seat away from the fixing plate; the circular hole and the mounting holes facilitate installation on the motor, and are easy to install and use.

[0007] Preferably, a plurality of positioning slots matching the blades are provided at one end of the cover plate close to the fixing plate, and connecting columns are installed on the blades, and fixing holes matching the connecting columns are provided in the positioning slots of the cover plate; the cover plate is fixedly connected to the blades through the cooperation of the positioning slots and the blades, and the connecting columns are inserted into the fixing holes, which is convenient for production and assembly.

[0008] Compared with the prior art, the utility model has the following beneficial effects: when in use, the motor drives the connecting seat to rotate, and the connecting seat drives the fixed disk and the blades to rotate. The cutting blades can first cut the fluid to reduce the pressure pulsation of the fluid. After the fluid pressure pulsation is reduced, the blades will throw the fluid out, thereby achieving the purpose of reducing the noise and vibration of the water pump.

[0015] In order to facilitate the understanding of the utility model, the utility model will be described more comprehensively below with reference to the relevant drawings. The utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the utility model more thorough and comprehensive.

[0016] like Figures 1 to 5 As shown, a fixing plate 2 is fixedly installed at one end of the connecting seat 1, and a plurality of blades 3 are evenly arranged and installed on the fixing plate 2. A cover plate 5 is connected to the other end of the blade 3. Cutting blades 4 are installed on the plurality of blades 3. The cutting blades 4 are arranged in a shark fin shape. The cutting blades 4 gradually expand from the outside to the inside and completely match the blades 3. A circular hole is opened in the middle of the connecting seat 1, and a plurality of mounting holes are opened at the end of the connecting seat 1 away from the fixing plate 2. A plurality of positioning slots matching the blades 3 are opened at the end of the cover plate 5 close to the fixing plate 2, and a connecting column 6 is installed on the blade 3. A fixing hole 7 matching the connecting column 6 is opened in the positioning slot of the cover plate 5.

[0017] The cover plate 5 is fixedly connected to the blade 3 by cooperating with the positioning slot and the blade 3, and the connecting column 6 is inserted into the fixing hole 7, which is convenient for production and assembly. It is convenient to install on the motor through the circular hole and the mounting hole, and is convenient for installation and use. When in use, the motor drives the connecting seat 1 to rotate, and the connecting seat 1 drives the fixing plate 2 and the blade 3 to rotate. When rotating, the cutting blade 4 cuts the fluid to reduce the pressure pulsation of the fluid. The shark fin-shaped cutting blade 4 can improve the cutting effect on the fluid, and the cutting reduces the pressure pulsation of the fluid. After the pressure pulsation of the fluid is reduced, the blade 3 throws the fluid out, thereby achieving the purpose of reducing the noise and vibration of the water pump.

[0018] like Figures 1 to 5 As shown, the utility model is an impeller for reducing pressure pulsation. When it is working, the motor drives the connecting seat 1 to rotate, and the connecting seat 1 drives the fixed plate 2 and the blades 3 to rotate. The cutting blades 4 can first cut the fluid to reduce the pressure pulsation of the fluid. After the fluid pressure pulsation is reduced, the blades 3 will throw the fluid out to reduce the noise and vibration of the water pump.
