近年来,磁力联轴器获得越来越广泛的应用,如磁力泵、磁力搅拌反应釜等。磁力联轴器结构中内转子处于腐蚀介质中,永磁体必须用包套(通常铬镍奥氏体不锈钢)加以保护。因此需解决包套和内转子座带磁进行焊接的问题。 1 磁干扰的产生 焊接件由内转子座、永磁体和包套组成(如图1)。内转子座加工至要求尺寸并粘上永磁体后与包套装配,产生了两处需密封焊接的焊

In recent years, magnetic coupling has been more and more widely used, such as magnetic pump, magnetic stirring reactor. In the magnetic coupling structure, the inner rotor is in a corrosive medium and the permanent magnets must be protected by a sheath (usually chromium-nickel-austenitic stainless steel). Therefore, it is necessary to solve the problem that the sleeve and the inner rotor seat are magnetically welded. A magnetic interference welding parts from the inner rotor seat, permanent magnet and the envelope (Figure 1). Inner rotor seat processing to the required size and stick to the permanent magnet and the package assembly, resulting in two to be sealed welding
