In contrast to induction heating devices, induction heating units with medium frequency technology are suitable for both thermal mounting and thermal dismounting. Induction heating equipment can also be used to heat very large and heavy components.
In most cases, adequate expansion of the bearing is achieved at temperatures between +80 °C and +100 °C. In the heating process, the maximum heating temperature must be observed. In bearings, the temperature must not exceed 120 ºC, otherwise the structure and hardness of the bearings may be adversely affected. All heating equipment allows a continuous adjustment of the temperature.
Thanks to their high degree of flexibility and their compact design, these units can also be used in mobile applications. Thus, they can be used, for example, on wind turbine sites or for other large and difficult to transport components.
Each unit is made up of a generator and an inductor that is positioned on the part to be heated. Depending on the requirements, a rigid or flexible inductor is used. Flexible inductors are used to wrap the hole or the outer diameter of the part, depending on the specific application.
Flexible induction melting furnace supplier provides you suitable for heating bearing inner rings and large components such as machinery mounts in wind turbines. The length of the inductor is determined in relation to the dimensions of the part.
Rigid inductors are especially suitable for series applications. Here, flexibility has a lower priority, short lead times and a high level of process security are more important.
Induction heating units with medium frequency technique have the following advantages:
- Suitable for mounting
- Suitable for disassembly
- Working frequency from 10 kHz to 25 kHz
- Generator efficiency greater than 99%
- Low energy consumption
- Short heating times
- Heating with time and temperature control as well as other operating modes
- automatic degaussing
- Possibility of flexible and rigid inductors
- Use of inductors inside and outside the part
- Lower mains connection power compared to mains frequency heating devices
- Almost silent operation
- air cooled system
General Reasons for Using HEAT GENERATOR Devices
Greater efficiency
HEAT GENERATOR devices make it possible to considerably reduce energy costs. With an efficiency level of over 90%, the HEAT GENERATOR operates with a significantly higher level of energy efficiency than conventional heating devices.
Higher productivity
HEAT generator induction power supply devices heat components faster than mains frequency devices, increasing productivity.
Greater flexibility
The HEAT GENERATOR is considerably more compact and 40% lighter than the previous generation, making them mobile units and suitable even for hard-to-reach areas. Mounting and removal tasks can be performed using flexible or rigid inductors depending on the application.
Greater security
Temperature control allows easy and safe handling and prevents excessive heating of the part.
Characteristic
For large and heavy components:
- digital control system
- Control via touch panel
- It includes a generator and an inductor that can be rigid or flexible.
Rigid Inductors:
- They are manufactured specifically for the application
- They are light and can be easily placed on the piece
- They are especially suitable for dismounting bearing rings, labyrinth rings and axlebox bearings in mass production.
Flexible Inductors:
- They are similar to cables and are used to wrap holes or be placed on the outside of the piece
- They have a length of up to 40 meters depending on the application
- They are exceptionally adaptable to a wide variety of parts and particularly suitable for large bearings, gears, housings, etc.
