WTR Bearing Induction Heaters
WTR Bearing Induction Heater Application
WTR Bearing induction heater, widely used in enterprises of manufacturing and maintenance from the line of railway, oil, machinery, motor and others, which is for heating of the surplus assemble of the bearings, couplings, gears, bushings, etc .
WTR Bearing Induction Heater Operating Principle
Using electromagnetic induction principle, make the bearing as a secondary coil, when connected power, from the inner to the outer will lead to thermal expansion, which will meet the surplus over assembly.
1. Improving assembling quality, even heating and high precision, keeps the workpieces surface hardness and the inherent quality.
2. Enhanced work efficiency and fast heating speed help to reduce the labor intensity as well as accelerate the assembling process, to achieve the civilized production
3. Reasonable structure, advanced and easy operating, safe without fire danger.
4. Achieving the energy conservation, cost reduction and benefit improvement. To save oil 100% than Oil Heating, 60% power than the electrical stove heating.
5. After the heating stop, WTR Bearing Induction Heater will degauss to less than 0.8mT, according to the ZJS-004 standard. WTR series Bearing Induction Heater is the ideal heating device for the civilized production, high-efficient production and safety production.
6. Add a little grease to the yoke and shank to increase the cohesive force and decrease noise when the heaters working.
WTR heaters adopt time and temperature methods to control the heating. You could know the heating speed and heating temperature directly by the numerical Representation. The heating time could be adjustable from 0 to 99 minutes, heating temperature could be adjustable from 0-300 degree.
