Technical Field
[0001] This utility model relates to the field of water pump technology, and in particular to a complete set of water pump inlet and outlet equipment with a quick-release structure. Background Technology
[0002] A water pump is a widely used device in the field of liquid transportation. Its main function is to generate power through the rotation of an impeller, thereby realizing the intake and discharge of liquids. In existing technology, water pumps typically consist of a motor, an impeller, and a casing. The casing houses the impeller and forms a working chamber, while the motor drives the impeller to rotate via its output shaft, achieving the pumping action. This type of equipment has a simple structure, stable operation, and can meet the basic requirements of various applications.
[0003] With the continuous development of water pump technology, its application scope is expanding, especially in agricultural irrigation, industrial circulation, and building water supply, where it plays a vital role. Highly efficient and reliable water pump equipment is crucial for improving production efficiency and reducing energy consumption; therefore, optimizing and improving water pump structures has always been a key focus of technological research.
[0004] However, existing water pump equipment has certain structural design flaws. Specifically, the casing of traditional water pumps is mostly one-piece or fixedly connected, making the disassembly process complex and time-consuming when the impeller is damaged or requires maintenance. This structural inconvenience not only increases the difficulty of maintenance but also affects the efficiency of the equipment. Especially under high-frequency use or harsh operating conditions, the impeller is easily damaged, and the time cost required to replace the impeller is high, limiting the overall performance and economy of the water pump. Utility Model Content
[0005] The purpose of this utility model is to provide a complete set of water pump inlet and outlet equipment with a quick-release structure to solve the problems existing in the prior art.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A water pump inlet and outlet assembly with a quick-release structure includes a waterproof motor, an impeller, a first cover plate, and a second cover plate. The first and second cover plates form a chamber for mounting the impeller. The waterproof motor is detachably mounted on the first cover plate. The output shaft of the waterproof motor passes through the first cover plate and extends into the chamber. The impeller is sleeved on the section of the waterproof motor's output shaft located within the chamber. The waterproof motor drives the impeller to rotate. An outlet is provided at the joint of the chamber formed by the first and second cover plates. An inlet is provided at the center of the side of the second cover plate opposite to the first cover plate. A sealing ring is provided at the joint of the first and second cover plates.
[0007] By adopting the above technical solution, the impeller may be damaged more quickly due to the usage scenario. In this case, only the impeller needs to be replaced. However, because the existing equipment is inconvenient to disassemble, the impeller requires a long maintenance time. This solution uses the first cover plate and the second cover plate to form a working chamber for accommodating the impeller, which makes it easy to disassemble and replace during maintenance, greatly saving the maintenance and replacement time of the impeller.
[0008] In a further embodiment, the second cover plate has a cylindrical shell structure, and the end of the second cover plate near the first cover plate is completely open. An extension edge is provided on the outer side of the open end of the second cover plate, and circular holes are uniformly arranged axially on the extension edge. A through hole corresponding to the circular hole is provided on the first cover plate. A protruding ring is provided on the mating surface of the extension edge and the first cover plate. An annular groove corresponding to the annular groove is provided on the first cover plate, and the sealing ring is located in the annular groove.
[0009] By adopting the above technical solution, the cooperation between the ring and the ring groove enables the positioning accuracy control of the first cover plate and the second cover plate. During use, the bolts, nuts and the cooperation of the round holes and through holes are used to lock and fix them. When necessary, anti-vibration bolts can be used.
[0010] In a further embodiment, a positioning hole is provided at the center of one end of the impeller near the inner wall of the second cover plate, and a grid is fixedly installed inside the water inlet of the second cover plate, with a positioning cylinder corresponding to the positioning hole at the center of the grid.
[0011] By adopting the above technical solution, impeller vibration caused by different coaxiality can be avoided when rotating at high speed.
[0012] In a further embodiment, all acute angles of the second cover plate are provided with rounded transition structures.
[0013] In a further embodiment, the second cover plate has a concentric flange at one end near the first cover plate, and the connection between the flange and the inner wall of the second cover plate is a rounded transition structure.
[0014] In a further embodiment, the sealing ring is a heat-resistant, high-strength modified PET material.
[0015] In summary, this utility model has the following beneficial effects: 1. The working chamber for housing the impeller is formed by splicing the first cover plate and the second cover plate, which makes it easy to disassemble and replace during maintenance, greatly saving the maintenance and replacement time of the impeller.
