Considerations for using bearing heaters

Electrical equipment is an indispensable equipment in our life. The heater is the equipment that we use in the production and processing activities. With the development of modern production technology, there are many types of bearing heater, heater is one of them, bearing heater heating equipment is relatively safe, but when in use may encounter a variety of problems, the specific contents are as follows: the grounding wire must complete 1 power supply. Bearing heater power wiring, power supply should be applied 380V three-phase four wire power supply. 2 the motherboard does not arrange the yoke, press the start button switch is prohibited, otherwise will damage the instrument or discard the fuse. 3 please do not put the magnetic probe on the heating workpiece, in order to extend the life of the probe, heating uniform bearing, even if the use of time control to extend the life of the probe. 4 bearing heater temperature must not exceed 120. Otherwise it will make the bearing annealing. 5 bearing temperature, the diameter of the expansion of the reference diameter of the bearing temperature coefficient of contraction. Take the workpiece to pay attention to low temperature, in order to prevent burns. 6 in order to improve the heating to the inner hole of the bearing yoke, according to size selection response, should try to choose a larger cross sectional area of yoke. The 7 Party is required when the motherboard power, heating parts in desirable yoke. The board must be neat arrangement, not skewed, the yoke and the motherboard must conform to the end.
