Introduction to the application of electromagnetic heating in hot installation and hot removal

Electromagnetic heating assembly and disassembly equipment is primarily used for the thermal assembly and disassembly of interference-fit parts such as large motors, motor stators, rotors, large bearings, rolls, couplings, and other workpieces. Traditional methods for interference-fit assembly and disassembly of workpieces involve baking or oil boiling. These methods are time-consuming and labor-intensive, unsafe and environmentally unfriendly, and difficult to control temperature, leading to wasteful resources.

Traditional domestic induction heating power supplies generally utilize analog control circuits, which present numerous inherent disadvantages for both manufacturers and users:

1) Analog control circuits utilize a large number of discrete components and circuit boards, inevitably leading to higher hardware costs and reduced system reliability;

2) The need for manual adjustment of components, such as adjustable potentiometers, reduces production efficiency and control system consistency;

3) Component aging and thermal drift can lead to reduced output performance of the induction power supply;

4) Product upgrades are difficult, requiring modifications to the control system, which in turn requires hardware improvements;

5) Analog control systems offer limited monitoring capabilities. In the event of a fault, they are generally limited to audible and visual alarms, which is extremely inconvenient.

Electromagnetic induction heating can effectively avoid the negative impacts of traditional processes in shrink assembly and removal of interference fits. Its advantages over traditional heating processes include:

1) Electromagnetic induction heating utilizes the principles of electromagnetic induction and the Joule effect to heat the workpiece. Simply turning on the power supply is quick and convenient, and once heating is complete, simply turning off the power eliminates any waste of resources.

2) It heats quickly and precisely, eliminating issues such as workpiece deformation caused by inadequate temperature control, excessive temperatures, or workpiece failure due to insufficient temperature control.

3) Electromagnetic induction heating requires minimal labor. Compared to traditional shrink assembly and removal processes, it can save significant human resources, significantly reducing labor costs for businesses.

4) Assembly and disassembly using electromagnetic induction heating is easier to automate.
