Compared with other insulation treatment processes, what are the advantages of electric heating dip varnish?

With the development of motor manufacturing technology, the winding insulation process has been continuously changed and upgraded. VPI vacuum pressure dipping equipment has become the standard configuration process for most motor manufacturers and repair companies. The traditional immersion and drip immersion process is relatively rare in motor manufacturing enterprises, and only exists in some small motor repair shops.

The traditional winding insulation treatment process includes three steps of preheating, dipping and drying of the object to be treated. Most of the preheating and drying use high temperature ovens, which are three different and discontinuous work. equipment combination . But no matter which process is used, there are some potential problems without exception, such as: (1) poor curing effect and poor appearance quality; (2) unstable paint quantity and uneven distribution of impregnating paint; ( 3) It is difficult to clean the residual paint on the inner and outer surfaces of the iron core, and the cost of materials and labor is high; and there is the problem of interference with the parts and components; (3) The discontinuity of the process and process leads to environmental pollution and material waste; (4) Baking During the drying process, due to the uneven furnace temperature, the heated parts are heated unevenly, and even quality failures such as local scorching occur.

I recently browsed the Internet and found out about the process of electric heating dipping paint curing. It is my occupation, so I read the relevant materials; when I communicated with a friend, I also had a preliminary understanding of the electric heating dipping paint process, which is a kind of traditional immersion process. Essential improvement, the special feature of this process is the pertinence of heating, that is, only the winding part is heated, and the dipping process will not pollute the surface of the iron core, which ensures the quality of dipping and effectively improves the clean production. feasibility.

The technological advantages of the electric heating dipping equipment are: (1) The equipment occupies a small area and can be flexibly arranged according to the production logistics; the process is flexible, and the production organization is easy; labor saving; (2) It is suitable for continuous mass production and flow of stator (3) Three-phase AC heating method is adopted, the heating is more uniform, the speed is faster, and the production efficiency is high; the electric heating controls the temperature accurately, and the paint content is accurately controlled; Remove the lacquer tumor or reduce the lacquer tumor; (5) After the cooling device, the stator can be directly transferred to the next process.

This process can better ensure the amount of paint hanging on the winding and the curing effect, and at the same time reduce the loss of dipping paint during operation; from the perspective of environmental protection and energy saving, it has a certain promotion value.
