Abstract
Description
Technical Field
[0001] This utility model relates to the field of water pump impeller technology, specifically to a corrosion-resistant automotive water pump impeller. Background Technology
[0002] Pump impellers are made of cast iron, and the blades on the impeller play a major role. The shape and size of the pump impeller are closely related to the pump's performance. Pump impellers can generally be divided into single-suction and double-suction types. Single-suction impellers draw water from one side and are mostly used in small-flow pumps. Double-suction impellers draw water from both sides and are used in large-flow pumps. Currently, to ensure the quality of impeller use, they are generally treated with anti-corrosion coating.
[0003] Existing technologies often use epoxy resin and polyurethane coating materials to coat the impeller surface to improve its corrosion resistance. However, the coating is easily washed away by water over a long period of time, which affects its service life. Therefore, a corrosion-resistant automotive water pump impeller is proposed, which is easy to cover the impeller surface for corrosion protection and is easy to replace later. Utility Model Content
[0004] To address the problems in the existing technology, this utility model provides a corrosion-resistant automotive water pump impeller, which is easy to cover the impeller surface for corrosion protection and is convenient to replace later.
[0005] The technical solution adopted by this utility model to solve its technical problem is a corrosion-resistant automotive water pump impeller, including an impeller body, blades and a protective component, wherein the protective component includes a protective cover and a disassembly strip;
[0006] The top surface of the impeller body has mounting holes on both sides corresponding to the blades, and the surface of the disassembly strip has disassembly holes at the positions corresponding to the mounting holes.
[0007] By adopting the above technical solution, protective covers are respectively attached to the outer surface of the blades at the top of the impeller body to protect them from corrosion. The protective covers are made of PVC material, which has excellent corrosion resistance and can resist the erosion of various chemicals such as acids, alkalis, and salts. Furthermore, the surface of the protective covers is coated with an epoxy resin coating, which further enhances the corrosion resistance.
[0008] Meanwhile, the mounting holes on the impeller body surface allow the protective cover to be bolted on and off through the mounting holes on the sides of the mounting strips, facilitating the replacement of the protective cover later and making the replacement process convenient.
[0009] Specifically, blades are evenly arranged around the center position on the top periphery of the impeller body.
[0010] By adopting the above technical solution, the main function of the blades on the impeller body is to convert the fluid into energy through the rotation of the impeller, thereby realizing the pumping function of the pump.
[0011] Specifically, the protective covers are all clipped onto the top surface of the blades, and the protective covers are provided with disassembly strips on both sides.
[0012] By adopting the above technical solution, protective covers are used to cover the outer surface of the blades at the top of the impeller body to protect them from corrosion and other damage.
[0013] Specifically, the disassembly strips are all fixed to the mounting holes by disassembly bolts, and the surfaces of the protective cover and the disassembly strips are coated with an anti-corrosion layer, which is an epoxy resin coating.
[0014] By adopting the above technical solution, the mounting holes on the surface of the impeller body are used to facilitate the bolt installation and removal of the guard through the mounting and removal holes on the surfaces of the two side mounting strips, so as to facilitate the replacement of the guard in the later stages.
[0015] Specifically, both the protective cover and the disassembly strip are made of PVC material.
[0016] By adopting the above technical solution, the protective cover and disassembly strip are both made of PVC material, which has excellent corrosion resistance and can resist the erosion of various chemical substances such as acids, alkalis, and salts.
[0017] The beneficial effects of this utility model are:
[0018] (1) The corrosion-resistant automobile water pump impeller of this utility model is protected by a cover that is respectively clamped on the outer surface of the blades at the top of the impeller body for corrosion protection. The cover is made of PVC material, which has excellent corrosion resistance and can resist the erosion of various chemicals such as acids, alkalis, and salts. The surface is coated with an anti-corrosion layer of epoxy resin coating, which further enhances the corrosion resistance.
[0019] (2) The corrosion-resistant automobile water pump impeller of this utility model has mounting holes on the surface of the impeller body so that the protective cover can be bolted on and off through the mounting holes on the surface of the two side mounting strips, so that the protective cover can be replaced later.
