GJT30H-G type piston heater

. Changzhou Jun
Piston heater
Suitable for rapid heating of pistons of various single-cylinder and multi-cylinder machines. It is the largest piston heating in China/
Piston induction heating/< br/>Inductive piston heating/
Manufacturer of piston heating machines, with a far leading market share
. It can quickly heat the piston pin hole to achieve the effect of interference assembly, and is used for pistons on power machinery equipment assembly lines. Interference assembly, such as internal combustion engine and diesel engine industry. After assembly, the inner hole of the piston is naturally cooled, and the shaft and pin fit closely together to achieve the purpose of interference assembly of the piston by the manufacturer.

The induction heater adopts an advanced electronic time (or temperature) control circuit, and operates according to the setting within the range of
, (
or
,
℃). Fixed value automatic timing (or fixed temperature). 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. Applicationbr/,
series heaters are mainly used for heating bearings, gears, ring gears, motor aluminum shells, pistons
, connecting rod small ends, wheel cores, wheel hoops, etc. Various types of metal parts are heated and expanded to meet the needs of interference assembly or disassembly.
2. Structure and working principle
●
Structure

,
The series heater is composed of a dry self-cooling power frequency induction 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 wear 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 group) and is heated. , eddy current heating
The heated workpiece and the iron core of the host form a closed When the magnetic circuit is working, the magnetic field lines passing through the host generate eddy currents in the workpiece and are quickly heated.
