How Bearing Heaters Work

The working principle of the bearing heater is to use the metal to generate eddy current in the alternating magnetic field to make itself heat, which is usually used in metal heat treatment and so on. The principle is that when a thicker metal is in an alternating magnetic field, an electric current is generated due to the phenomenon of electromagnetic induction. After the thicker metal generates current, the current will form a spiral flow path inside the metal, so that the heat generated by the current flow is absorbed by the metal itself, which will cause the metal to heat up quickly.
Installation and debugging
1. Short-circuit heating: The host is a transformer with a special structure, and the movable yoke is used to directly pass through the bearing or other heated workpieces. When working, turn on the power of the host, and the workpiece (equivalent to the secondary winding) induces a short-circuit current and is heated.
2. Place the yoke on the end face of the main iron core.
3. Check whether the wiring between the plug and the socket is consistent, the grounding should be good, and then insert the plug into the power socket with the control switch.
4. Turn the function selection switch to the manual position, turn on the power, and the red indicator light is on.
5. Press the start button, the host is powered on, then the green indicator light will turn on and the red light will turn off; press the stop button, the red light will turn on and the green light will turn off. At this point, the debugging is over and it can be put into use.
operating procedure
The first step is to place the yoke on the end face of the main unit.
The second step is to insert the plug into the power socket with the control switch.
The third part, check whether the ground wire is good, and test it with a test pen after powering on.
The fourth step is to turn on the power according to the requirements. At this time, the host automatically detects the probe and the ambient temperature, and displays the ambient temperature at the same time.
The fifth step, check that the yoke should have no voltage to the ground.
The sixth step, select the yoke sleeve according to different specifications of bearings or other workpieces, and place the yoke on the top surface of the main machine, which should be flat.
The seventh part, press the button to select the temperature or time control, if you need to adjust the temperature or time, please press the up or down button to select the appropriate parameter.
The eighth step, press the start button. The host starts to heat the workpiece. When the set time is reached, the host automatically stops heating and automatically demagnetizes the workpiece. During temperature control, when the set temperature is reached, the workpiece is in a constant temperature state, and when it needs to be installed, just press the stop button. .
The ninth step, when the bearing is heated to the required temperature, it will automatically turn off the power or press the stop switch.
The tenth step, after the heating is stopped, move the yoke to the left or right, remove the bearing and put the yoke back on the top of the host.
Eleventh, if the machine is reused to continuously heat the bearing, it is only necessary to put the processed bearing into the yoke and press the start button.
