The working principle of bearing heater and its eight characteristics

The bearing heater consists of a dry self-cooling power frequency induction heating device referred to as the host and control equipment.

Bearing heater working principle:

1. 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 power supply of the bearing heater is turned on, and the short-circuit current is induced in the workpiece (corresponding to the secondary winding) and heated.

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.

Eight characteristics of bearing heater

1. The heating speed is fast, and the temperature display can control the heating process.

2, the new eddy current induction design, using the international advanced "FuzzyControl" and "NeuralNetowrk" technology.

3, can work continuously, output power is high, high efficiency

4, the heating process is safe and reliable, the British Royal Sun United Insurance Company underwriting.

5, can be heated with sealed bearings (ZZ, 2RS)

6, rotating (hydraulic) rocker arm or hinged heating rod design, more convenient to use.

7, heating process can display heating time

8, no open fire, no pollution, environmental protection, no accidents.

Bearing heater range

The bearing heater is suitable for machinery manufacturing and maintenance in the fields of power plants, textile mills, paper making, chemical industry, petroleum, machinery, mining machinery, maintenance of wind power industry, etc. It can be used as bearings, connectors, gears, mechanical bushings, etc. The workpiece is heated and automatically demagnetized, so that the workpiece is cylindrically expanded to meet the requirements of interference assembly. The heater is controlled by microcomputer, which can automatically detect the equipment failure, automatically adjust the heater power, and soft start/stop.
