[0003] When the magnetic pump is running at high speed, the temperature inside it will become higher and higher, and the outer magnetic rotor and the inner rotor will also increase. At present, the heat dissipation of the outer magnetic rotor and the inner rotor mostly relies on passive heat dissipation. When the magnetic pump transports high-temperature liquid, coupled with the outer magnetic rotor and the inner rotor heating up due to rotation, passive heat dissipation is difficult to cool down quickly, resulting in a reduction in the delivery capacity of the magnetic pump.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] Example:
[0019] See also Figure 1-4 The utility model provides a technical solution: a magnetic pump bracket, including a connecting bracket 10, a plurality of support bars 11 are fixedly connected to the surface of the connecting bracket 10, and a plurality of flow holes 12 are provided on the surface of the support bar 11. The flow holes 12 can prevent the support bar 11 from blocking the flow of the medium, which helps to increase the flow speed of the medium and improve the heat conduction efficiency of the connecting bracket 10;
[0020] The casing 4 is sleeved on the surface of the connecting bracket 10, and the casing 4 is fixedly connected to the support bar 11. A flow channel is formed between the casing 4, the support bar 11, and the connecting bracket 10, so that the medium flows in from the bottom of the casing 4 and flows out from the top of the casing 4, ensuring that the medium can fill the casing 4 and evenly dissipate heat for the connecting bracket 10;
[0021] The upper and lower surfaces of the casing 4 are respectively provided with a discharge joint 5 and an inflow joint 6 , and the discharge joint 5 and the inflow joint 6 are both connected to the flow channel to facilitate the cooling medium to flow in and out of the casing 4 .
[0022] In this embodiment, if Figure 1 As shown, the left and right ends of the connecting bracket 10 are respectively connected to a flange 8 and a connecting plate 1, and the side of the connecting plate 1 is fixedly connected to a perforated plate 2. The flange 8 is used to facilitate the connection between the connecting bracket 10 and the motor, and the perforated plate 2 is used to facilitate the connection between the connecting bracket 10 and the impeller pump casing.
[0023] In this embodiment, if Figure 1 As shown, a drain pipe 9 is installed on the lower surface of the casing 4, and a sealing cap 7 is screwed on the surface of the drain pipe 9. A sealing ring 14 is provided inside the sealing cap 7, and the sealing ring 14 abuts against the drain pipe 9. The use of the sealing ring 14 can improve the sealing effect between the sealing cap 7 and the drain pipe 9. When the connecting bracket 10 dissipates heat normally, the sealing cap 7 blocks the drain pipe 9 to ensure that the medium can circulate. When it is necessary to clean the stains inside the casing 4, the sealing cap 7 can be unscrewed to open the drain pipe 9 and discharge the stains at the bottom of the casing 4.
[0024] In this embodiment, if Figure 1 As shown, a support frame 3 is fixedly connected to the surface of the connection plate 1, and the support frame 3 can be connected to the base of the magnetic pump to support the magnetic pump bracket and improve the stability of the installation of the magnetic pump bracket.
[0025] In this embodiment, if Figure 1 As shown, a lifting ring 13 is installed on the upper surface of the casing 4, and the magnetic pump bracket can be conveniently lifted by the lifting ring 13, so that the magnetic pump bracket can be easily moved after installation.
[0026] Specifically, when in use, the pipe joints for conveying the medium are respectively connected to the discharge joint 5 and the inflow joint 6. When the magnetic pump is working, the heat generated by the rotation of the outer magnetic rotor and the inner rotor is first transferred to the connecting bracket 10. When the heat dissipation medium flows between the connecting bracket 10 and the casing 4, the flowing medium is used to take away the heat on the connecting bracket 10, which can reduce the temperature of the outer magnetic rotor and the inner rotor and maintain the conveying capacity of the magnetic pump.
[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
