GJT30K type small coupling heater

Small coupling heater, suitable for rapid heating of small couplings, gears, ring gears, end covers, etc.

,
Induction heating The device uses an advanced electronic time (or temperature) control circuit to automatically time (or fix the temperature) according to the set value within the range of
, (
or
,
℃). The upper limit of time (or temperature
, )
can be set. When heating the workpiece, when the set upper limit is reached, the heater will automatically cut off the circuit and issue an over-temperature alarm indication. Timing or constant temperature digital display, intuitive and accurate. The operator can know the temperature changes of the inner ring of the heated workpiece and the heating time changes at any time. During heating, only the workpiece is heated, while the heater itself remains at normal temperature. It overcomes the problems of channel damage, loud noise, reduced service life and environmental pollution caused by original installation methods such as hammering of workpieces, flame heating, and oil boiling heating.
. 1. Application br/ ,
Series heaters are mainly used to heat various types of bearings, gears, ring gears, motor aluminum shells, pistons, connecting rod small ends, wheel centers, wheel hoops, etc. The metal parts are heated and expanded to meet the needs of interference assembly or disassembly.
. 2. Structure and working principle
. ●
Structure

,
The series heaters are composed of dry self-cooling power frequency induction heating devices (below Referred to as the host) and control equipment.
. ●
Working principle
,
, short-circuit heating
The host is a transformer with a special structure. The movable yoke is used to directly wear bearings or other objects. Heating the workpiece. When working, when the main machine is powered on, a short-circuit current is induced in the workpiece (equivalent to the secondary side assembly) and is heated. ,
or eddy current heating
The heated workpiece and the iron core of the main machine form one When the closed magnetic circuit is working, the magnetic field lines passing through the host generate eddy currents in the workpiece and are rapidly heated.

Operating procedures
. .
Place the workpiece between the main machine core and the yoke and ensure that the workpiece is in the core,
/>Put down the movable yoke,
make it close to the workpiece
. .
Put the function switch to the manual position, press the start button, the green light will be on, the red light will be off, and the host will work
The timer starts timing. When the workpiece is heated to the temperature required for assembly, record the heating time and press the stop button. The red light is on, the green light is off, the host stops working, and the workpiece is ready for assembly
. .
. When heating workpieces of the same specifications in batches, just put the function switch in the automatic position
and set the timer to the time value recorded during manual heating, load the workpieces, and press the start button to start heating.
When the heating reaches the set time (that is, the required temperature rise value is reached), the heating automatically stops
. .
After the work is completed, turn off the branch air switch and the main air switch.
