The induction heater adopts advanced electronic time (or temperature) control circuit, which can be operated in
'(
or
'
℃) and automatically time (or fix the temperature) according to the set value. The upper limit of time (or temperature
')
can be set. When heating the bearing, 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 knows the temperature changes of the inner ring of the heated bearing and the changes in heating time at any time. During heating, only the bearings heat up, 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 bearing knocking, flame heating, and oil boiling heating.
1. Purposebr/> '
Series heaters are mainly used for heating various types of bearings, gears, ring gears, motor aluminum shells, pistons, connecting rod small ends, wheel cores, 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
'
'
Series heaters are driven by dry self-cooling power frequency induction It consists of a heating device (hereinafter referred to as the host machine) and control equipment.
●
'
Working principle
'
'
, short-circuit heating
'
The host is a transformer with a special structure. The movable yoke is used to directly insert bearings or other heated workpieces. When working, turn on the power of the host, a short-circuit current is induced in the workpiece (equivalent to the secondary side assembly) and is heatedbr/> '
, eddy current heating
'
The heated workpiece and the host The iron core forms a closed magnetic circuit. When working, the magnetic field lines passing through the main machine generate eddy currents in the workpiece and are rapidly heated.
'
3. Operation procedurebr/>
'
According to the inner diameter of the bearing, select the corresponding yoke, and place the yoke of the sleeve bearing on the end face of the core of the main machine They should be in contact and consistent (otherwise the noise will be too loud)
'
During the heating process, use a point thermometer to measure the temperature rise at the end plane of the inner ring of the bearing. When the temperature rise meets the requirements, keep an eye on the time count, stop heating, remove the yoke, remove the bearing and assemble it. Continuously heat the bearings of the same specification and set the heating time. When the bearing is heated The power will be automatically turned off when the set time is reachedbr/> '
. After the work is completed, move the function selection switch to the stop position to cut off the power.
