The induction heating coil is the energy output device of the medium and high frequency induction heating equipment, which is wound by a hollow copper tube and can be cooled by water. What are the effects of improper induction heating coils on medium and high frequency induction heating equipment? The suitability of induction heating coil directly affects the effective output power, working efficiency, stability, reliability and service life of medium and high frequency induction heating equipment. The number of turns, shape, size of the induction coil, the material of the workpiece, the coupling position of the heating part and the induction coil, etc., these factors will affect the heating effect and the actual output power of the induction heating equipment. Today we are mainly to understand the number of sensor turns of high frequency induction heating equipment how to determine?
1. The number of turns of the induction coil of the medium and high frequency induction heating equipment is mainly determined by the power size, inner diameter size and working size of the medium and high frequency induction heating equipment.
2, such as steel and other ferromagnetic workpiece induction heating, generally preferred to use 2 to 4 rings of induction coil. If it is a material with poor magnetic conductivity such as copper, aluminum and other induction heating, the number of induction coils should be increased.
3, in general, the larger the diameter of the induction coil of the medium and high frequency induction heating equipment, the heavier the load (larger wall thickness or larger volume of the workpiece), the fewer the number of turns of the induction coil. The smaller the diameter of the induction coil and the lighter the load (small workpieces or thin-walled workpieces), the number of turns can be appropriately increased.
4, in principle, as long as the induction coil of the medium and high frequency induction heating equipment can be started normally, but if the induction coil with too many turns is used, the load of the medium and high frequency induction heating equipment will be heavy, affecting the service life, so please consider carefully.
5, here it is recommended that the manufacturer do not change the induction coil, the induction coil mismatch is easy to cause damage to the internal components of the high-frequency induction heating equipment, delay the normal production.
