Abstract

The invention discloses a magnetic pole protective coating vacuum desorption dipping solidification system, a vacuum desorption apparatus and a technology. According to the vacuum desorption technology, before injection of a dipping liquid, vacuum-pumping desorption is performed on an enclosed system formed by a magnet yoke in a magnetic pole and a vacuum bag, and a function relational expression of a degree of vacuum or pressure in the enclosed system is established so that a vacuum desorption process is controlled, wherein parameters of the functional relational expression comprise an average air exhaust volume flow of a vacuum pump, continuous time of vacuum-pumping, initial pressure in the enclosed system and initial volume of the enclosed system. In the desorption dipping system and system, the function relational expression provides a vacuum desorption standard, desorption time can be better grasped, and an effect of mutual examination with detected pressure is formed.

Description

technical field [0001] The invention relates to the technical field of electrodes, in particular to a vacuum desorption impregnation curing system for a magnetic pole protective layer, a vacuum desorption device and a process. Background technique [0002] Please refer to figure 1 , figure 1 It is a schematic diagram of the permanent magnet motor magnetic pole protection layer forming system; figure 2 for figure 1 Schematic diagram of the details of the middle magnetic steel. [0003] figure 1 Among them, the magnetic steel 16 is arranged on the inner wall of the magnetic yoke 15 of the outer rotor, pressed against the magnetic yoke 15 by a bead, and fastened by bolts. In addition, glue is injected on the surface of the magnetic steel 16 to form a protective layer 142 . The specific process is: [0004] First, cover the reinforcing material 142 (such as glass fiber cloth), release cloth 143, and flow guide net 141 on the surface of the magnetic steel 16, and then use ...
