Short-circuit heating: The main unit is a special-structure transformer. The movable yoke is used to directly pass the sleeve bearing or other heated workpiece. During operation, the main unit "target=_blank> is powered on, and the workpiece (corresponding to the secondary winding) is induced to generate a short-circuit current and is heated.
Installation and commissioning
2. Place the yoke on the end face of the main iron core.
3. Check that the wiring between the plug and the socket is the same, 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 and close the power supply. At this time, the red indicator light is on.
5. Press the start button, the main unit is powered on, then the green indicator light is red and the light is off; press the stop button, the red light is on and the green light is off. At this point, debugging is complete and ready for use.
Operating procedures:
1. According to the inner diameter of the bearing, select the corresponding yoke (see Table 2), and place the yoke of the bearing on the string on the end face of the main iron core, which should be square.
2. During the heating process, measure the temperature rise at the end of the bearing inner ring with a point thermometer. When the temperature rise meets the requirements, look at the time count, stop heating, remove the yoke, and remove the bearing to assemble.
3. Continuously heat the bearing of the same specification, set the function selection switch to the time control position, set the heating time, and automatically turn off the power when the bearing is heated to the set time.
4. After the work is completed, turn the function selection switch to the stop position and cut off the position. Http://news.chinawj.com.cn Editor: (Hardware Business Network Information Center) http://news.chinawj.com.cn
