Description

Technical Field

[0001] This utility model relates to the field of magnetic pumps, and in particular to a magnetic pump that is easy to assemble and disassemble. Background Technology

[0002] A magnetic drive pump is a type of pump that utilizes magnetic coupling for power transmission and is an important branch of the water pump field. It applies the principle of permanent magnet couplings to centrifugal pumps, achieving contactless torque transmission. A magnetic drive pump mainly consists of three parts: the pump body, the magnetic drive unit, and the electric motor. The magnetic drive unit is the core component, composed of an outer magnetic rotor, an inner magnetic rotor, and a non-magnetic isolation sleeve. When the electric motor drives the outer magnetic rotor to rotate, the magnetic field can penetrate the air gap and non-magnetic materials, driving the inner magnetic rotor, which is connected to the impeller, to rotate synchronously, thereby driving the impeller.

[0003] In current practical applications of magnetic pumps, the material conveying casing is typically fixed using bolt connections. While this design ensures structural stability and connection reliability to a certain extent,

[0004] However, materials may clump or deposit during transport. These solidified materials tend to accumulate inside the conveyor shell, eventually causing blockages. Once a blockage occurs, the material conveyor shell needs to be disassembled and cleaned. However, due to the presence of bolted connections, the disassembly process is relatively cumbersome and requires a significant amount of time and manpower.

[0005] Furthermore, the impeller of the magnetic pump, as a critical component, may wear or be damaged after prolonged operation, requiring replacement. Similarly, replacing the impeller also requires disassembling the material conveying casing, and the complexity of the bolted connections further increases the difficulty of disassembly, making maintenance work more time-consuming and labor-intensive.

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] like Figure 1 - Figure 4As shown, a magnetic pump that is easy to assemble and disassemble includes a magnetic pump housing 1, a mounting base 2, mounting holes 3, and a tail-end heat dissipation shell 4. The mounting base 2 is installed at the bottom of the magnetic pump housing 1 to ensure the stability of the overall structure. For ease of installation and maintenance, multiple mounting holes 3 are evenly distributed on both sides of the mounting base 2. The tail-end heat dissipation shell 4 is installed at the outer end of the magnetic pump housing 1, and its main function is to ensure the normal operation of the magnetic pump and extend its service life through effective heat dissipation.

[0029] At the front end of the magnetic pump housing 1, a first disassembly cover 5 and a second disassembly cover 6 are connected. Both disassembly covers have material compartments 11 inside for easy material storage and transportation. To ensure sealing performance, a sealing strip is designed at the joint between the first disassembly cover 5 and the second disassembly cover 6. Furthermore, to achieve quick assembly and disassembly, a sealing connecting ring 12 is provided at the connection between the first disassembly cover 5, the second disassembly cover 6 and the magnetic pump housing 1. A connecting rod 10 securely fixes the disassembly cover, the sealing connecting ring 12, and the magnetic pump housing 1, thereby simplifying the assembly and disassembly process.

[0030] The inner end of the sealing ring 12 is designed with arc-shaped encapsulation shells 14 at its upper and lower parts, respectively. The outer ends of these encapsulation shells are provided with encapsulation filler chambers 15 and overflow chambers 16. This design enables the encapsulation treatment at the joint between the first disassembly cover 5 and the second disassembly cover 6, ensuring the sealing performance of the entire magnetic pump.

[0031] To further enhance the sealing effect, a protruding ring and a recessed groove are designed at the joint of the first disassembly cover 5 and the second disassembly cover 6, respectively. The protruding ring of the first disassembly cover 5 can be perfectly embedded in the recessed groove of the second disassembly cover 6, and sealing strips are also provided at these protruding rings and recessed grooves to prevent liquid leakage.

[0032] Multiple insertion holes 13 are provided on the sealing ring 12, which are arranged in a ring to facilitate the insertion of the mating rod 10. Sealing rings are attached to both ends of the sealing ring 12 with adhesive. The insertion holes 13 are aligned with the openings on the disassembly cover and the magnetic pump housing 1 to ensure a tight connection.

[0033] The docking rod 10 features an ingenious design, consisting of a screw and a sealing washer. The screw passes through the disassembly cover and the sealing connecting ring 12, and is inserted into the magnetic pump housing 1. The sealing washer is placed between the end of the screw and the disassembly cover to prevent damage to the housing when the screw rotates. The end of the docking rod 10 also has a hexagonal hole for easy assembly and disassembly using tools.

[0034] Two arc-shaped encapsulation shells 14 are symmetrically distributed on the upper and lower parts of the sealing connecting ring 12. This design is not only aesthetically pleasing but also practical. The arc-shaped encapsulation shells 14 and the sealing connecting ring 12 are an integrated design, and they together cover the mating seam of the first disassembly cover 5 and the second disassembly cover 6 to ensure sealing performance.

[0035] To further improve the sealing effect, the encapsulation packing chamber 15 is filled with sealing packing material. This sealing packing material can be one or more of the following: stranded packing material composed of multi-strand fibers, polytetrafluoroethylene impregnated packing material, carbon fiber braided packing material, or mixed molded plastic packing material. Sealing strips are also designed on the edges of the arc-shaped encapsulation shell 14 and the sealing connecting ring 12 to prevent leakage of the sealing packing material. The overflow tank 16 is directly opposite the protruding tubes of the first disassembly cover 5 and the second disassembly cover 6. The overflow tank 16 allows the sealing packing material to overflow, thus ensuring the uniform distribution of the sealing packing material. Injecting sealant into the overflow tank 16 can further enhance the sealing effect.

[0036] To facilitate connection with other equipment, a first assembly base 7 is installed at the lower end of the first disassembly cover 5, and a second assembly base 8 is installed at the lower end of the second disassembly cover 6. The side walls of these two assembly bases are provided with mating holes 9, which facilitates quick connection and disassembly with other equipment.

[0037] Turn off the power to the magnetic pump and ensure there is no residual pressure in the system. Remove any other equipment from the mating hole 9 at the connection between the first disassembly cover 5 and the second disassembly cover 6. Use a suitable tool (such as a wrench or screwdriver) to loosen and remove the screw from the hexagonal hole at the end of the mating rod 10. When removing the mating rod 10, be careful not to lose the sealing gasket. Then, remove the first disassembly cover 5 and the second disassembly cover 6, paying attention to the position of the sealing strip to prevent damage. For further disassembly, continue to remove the first assembly base 7 and the second assembly base 8.

[0038] Install the first assembly base 7 and the second assembly base 8 onto the lower ends of the first disassembly cover 5 and the second disassembly cover 6. Align the first disassembly cover 5 and the second disassembly cover 6 and connect them to the magnetic pump housing 1, ensuring the sealing strip is correctly positioned. Insert the mating rod 10 into the insertion hole 13 of the sealing connecting ring 12, ensuring the screw passes through the openings in the disassembly cover and the magnetic pump housing 1. Place a sealing washer between the screw end and the disassembly cover, then tighten the screw to ensure a secure connection. Use a tool to tighten the screw in the hexagonal hole at the end of the mating rod 10 to ensure a tight seal. Next, connect the other equipment to the mating holes 9 of the first disassembly cover 5 and the second disassembly cover 6. Check the sealing performance of all connections to ensure there are no leaks. Turn on the power and check the operation of the magnetic pump to confirm that everything is normal.
