[0017] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.
[0018] Please refer to the accompanying Figs. 1-3 It is a high-efficiency self-cleaning water pump impeller structure disclosed by the present application.
[0019] The utility model discloses,
[0020] Mainly by impeller main body 1 constitutes, and impeller main body 1 includes hub 2 and the multiple blades 3 that evenly distributed along the circumference of hub 2.
[0021] First, regarding the design of blade 3.Cleaning edge 4 arranged on the surface of blade 3 is one of the key structures of realizing self-cleaning function.Cleaning edge 4 extends along the length direction of blade 3, and its height is usually set between 2-5 millimeters, for example, can be 3 millimeters.The spacing between adjacent cleaning edges 4 is kept at 5-10 millimeters, such as 8 millimeters.The top of cleaning edge 4 is arc-shaped, and the arc radius can be selected between 5-10 millimeters, such as 8 millimeters.This arc-shaped design can make water flow smoothly along the surface of cleaning edge 4 when passing through blade 3, reduce water flow resistance, and at the same time, when impurities in water contact blade 3, impurities will move along the arc surface of cleaning edge 4 to the drainage groove 5 between adjacent cleaning edges 4 due to the convex structure of cleaning edge 4.
[0022] The section of drainage groove 5 is trapezoidal, and the depth is shallow near hub 2, generally 3-5 millimeters, for example, 4 millimeters, and the depth is deep away from hub 2, and the range is 6-10 millimeters, such as 8 millimeters.During the high-speed rotation of the impeller, impurities will be quickly thrown to the deeper area outside the drainage groove 5 by the action of centrifugal force and discharged from the impeller with water flow.
[0023] Elastic scraper 6 is installed on the leading edge of blade 3.Elastic scraper 6 is made of elastic wear-resistant materials such as rubber or polyurethane, and its thickness is between 3-5 millimeters, for example, 4 millimeters, and the width is 10-20 millimeters, such as 15 millimeters.Elastic scraper 6 is installed at an angle of 30°-60° with the leading edge of blade 3, and 45° is a preferred implementation angle.When the impeller rotates, elastic scraper 6 first contacts impurities in the liquid, and due to its elastic properties, it can effectively scrape off impurities and prevent impurities from adhering to the leading edge of blade 3, and can also produce elastic deformation when encountering a larger impact force (such as collision with larger particle impurities), thereby avoiding damage to itself and blade 3.
[0024] The surface of hub 2 is provided with spiral guide groove 7.Spiral guide groove 7 extends from one end of hub 2 to the other end, and its pitch is between 10-20 millimeters, for example, 15 millimeters, and the spiral direction is accurately matched with the rotation direction of the impeller.When the impeller rotates, the liquid forms a spiral flow on the surface of hub 2 under the guidance of spiral guide groove 7.This spiral flow can enhance the scouring effect of the liquid on the surface of hub 2, effectively prevent impurities from depositing on the surface of hub 2, and on the other hand, it can also optimize the flow state of the liquid in the impeller, reduce flow disorder, improve the hydraulic efficiency of the water pump, and make the water pump more stable and efficient in conveying liquid during operation.
[0025] A plurality of drainage holes 8 are evenly distributed on the rear cover plate 9 of the impeller body 1. The drainage holes 8 are arranged in a ring array, and the diameter is between 5-10mm, for example 8mm. The axis of the drainage hole 8 is inclined to the rotation axis of the impeller at an angle of 45-75 degrees, for example 60 degrees. When the impeller rotates at high speed, under the action of centrifugal force, the impurities cleaned from the blades 3 and the hub 2 will be thrown in the direction of the rear cover plate 9 along with the liquid, and then quickly discharged outside the impeller through the inclined drainage holes 8, effectively avoiding the accumulation of impurities in the impeller, further ensuring the self-cleaning effect of the impeller and the continuous and efficient operation of the water pump.
[0026] In actual installation and use, the elastic scraper 6 is first firmly installed on the leading edge of the blade 3 at a predetermined angle to ensure its effectiveness and stability in scraping impurities. Then the blade 3 with the cleaning edge 4, the drainage groove 5 and the spiral guide groove 7 is precisely assembled with the hub 2 to ensure that the blade 3 is evenly distributed and firmly connected in the circumferential direction of the hub 2. Finally, the rear cover plate 9 with the drainage hole 8 is installed on the impeller body 1 to make the entire impeller structure complete. During the operation of the water pump, the impeller structure can fully play the functions of self-cleaning and optimizing the water flow, reduce the problems of water pump performance degradation caused by impurity blockage, prolong the service life of the water pump, and improve the overall operation efficiency and reliability.
[0027] In summary, the high-efficiency self-cleaning water pump impeller structure of the present application effectively solves the problems of easy blockage, difficult cleaning and affected hydraulic performance of traditional water pump impellers through the synergistic effect of each part, has obvious practicality and innovation, and can be widely applied to various water pump equipment to provide strong support for liquid conveying operations in related fields.
