[0020] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail in combination with the embodiments and the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. The technical solution of the present invention is described in detail below in combination with the embodiments and the accompanying drawings, but the scope of protection is not limited thereto.

[0021] like Figures 1 to 3 As shown, this embodiment provides a self-heating disassembly and reassembly tool for the magnetic pump isolation sleeve, including a circular pressure plate 1, a heat-conducting ring block 2, a first tie rod 3 and three second tie rods 4; the first tie rod 3 and the three second tie rods 4 are all screws with a length of less than 350 mm, and one end of the screw is processed with M10 thread and the other end is processed with M8 thread.

[0022] The circular pressure plate 1 is arranged on the outside of the magnetic pump body 5, and a hole for the first pull rod 3 to pass through is arranged in the center of the circular pressure plate 1. An elongated groove is milled on the circular pressure plate 1 around the center every 120° by a milling machine, and the elongated groove is used for three second pull rods 4 to pass through. Two connecting ear plates 11 are symmetrically arranged on the outer edge of the circular pressure plate 1, and holes are also arranged on the connecting ear plates 11.

[0023] One end of the first pull rod 3 is threadedly connected to the driving shaft 6 in the pump body 5 of the magnetic pump, and the other end of the first pull rod 3 passes through the hole in the center of the circular pressure plate 1 and is slidably connected to the circular pressure plate 1; a threaded hole is provided on the isolation sleeve 7, and the second pull rod 4 is threadedly connected in the threaded hole and connected to the isolation sleeve 7, and the other end passes through the circular pressure plate 1 and is connected to the circular pressure plate 1 by a bolt 8.
