The GHJ- N ( W ) gear heater is a highly efficient induction heating method using frequency conversion technology. The principle is to turn the power frequency power supply into a frequency of around 20KHZ and increase the frequency tracking technology. The heating device can be operated in an optimum state in the case where the workpiece to be heated is different. The thermal efficiency of its energy conversion can reach more than 98% .
The gear heater solves the problem of small-diameter large workpieces that cannot be solved by the power frequency heating assembly in the field of thermal assembly. ( The heating of the power frequency thermal assembly is caused by the iron core , so that there is a variable magnetic field in the workpiece ) and the gear heater does not need iron core ( silicon steel sheet ) . The inductor consists of a copper coil and a ferrite. (The sensor is made according to the hole size of the workpiece. ) The sensor is placed in the bore of the heated workpiece. After turning on the power, quickly heat the workpiece. The gear heater is a high-efficiency induction heating method that uses frequency conversion technology to replace thyristors with IGBT tubes.
Gear heaters have the advantages of fast heating speed, high thermal efficiency, light weight and durability. And set three control modes: 1. Time control 2. Temperature control 3. Temperature maintenance. And has an automatic demagnetization function.
