How bearing heaters work
2023-11-30 01:08:42
The working principle of the bearing heater is to use the metal to generate eddy currents in the alternating magnetic field and heat itself, usually used in the heat treatment of metals. The principle is that when a thick metal is in an alternating magnetic field, current will be generated due to electromagnetic induction. When the thicker metal generates current, the current will form a spiral flow path inside the metal, so that the heat generated by the current flow is absorbed by the metal itself, which will cause the metal to heat up quickly.
Like the other three Office Lighting, it can add emergency functions, dimming function and sensing functions. It can also be connected seamlessly. There are a variety of lengths to choose from: 2ft, 3ft, 4ft, 5ft, 6ft, 8ft. Generally, for the convenience of transportation, choosing a shorter size to splice is also a good choice.
Whether it is a corridor, a museum, a restaurant, or a kitchen, you can use this Up And Down Linear Lights to light up.
Installation and commissioning
1. Short-circuit heating: The main machine is a special-structure transformer. The movable yoke iron is used to directly wear sleeve bearings or other heated workpieces. During operation, the main unit is turned on, and a short-circuit current is induced in the workpiece (equivalent to the secondary winding) and is heated.
2. Place the yoke on the end face of the main core.
3, check the plug and socket wiring is consistent, the ground should be good, and then plug into the power outlet with a control switch.
4. Turn the function selection switch to the manual position and close the power supply. The red indicator light is on.
5, press the start button, the host power, then the green indicator light is red light; press the stop button, the red light is green. At this point, debugging is completed and it can be put into use.
Operating procedure
In the first step, place the yoke on the end face of the main machine.
In the second step, insert the plug into the power outlet with the control switch.
In the third part, check if the grounding line is good and test it with a pencil after power-on.
The fourth step is to turn on the power according to the requirements. At this time, the host automatically detects the probe and the ambient temperature and simultaneously displays the ambient temperature.
The fifth step, check the yoke should be no voltage to the ground.
The sixth step, according to different specifications of the bearing or other workpiece selection yoke sleeve, the yoke placed on the top surface of the host should be consistent with the formation.
The seventh part, press the button, select the temperature or time control, if you need to adjust the temperature or time, press the up or down key, select the appropriate parameters.
In the eighth step, press the start button. The main unit starts to heat the workpiece. When the set time is reached, the main engine automatically stops heating and automatically demagnetizes the workpiece. In the temperature control, when the set temperature is reached, the workpiece is in a constant temperature state. When it is required to install, press the stop button. .
In the ninth step, when the bearing is heated to the required temperature, it will automatically shut off the power supply or press the stop switch.
In the tenth step, after the heating is stopped, the yoke moves to the left or right. After the bearing is removed, the yoke is placed back on the top of the host.
In Part 11, if the machine is used repeatedly and the bearing is heated continuously, it is only necessary to insert the machined bearing into the yoke and press the start button.
When you look up, do you feel that your ceiling is too dark and feel depressed? Do you think the sky above the corridor is a little scary?
Then these Up and Down linear lights can solve your problem very well. Both the top and bottom of this Linear Light Led can emit light, the top is 30%, and the bottom is 70%. This Up And Down Light will make the entire space more spacious.
Like the other three Office Lighting, it can add emergency functions, dimming function and sensing functions. It can also be connected seamlessly. There are a variety of lengths to choose from: 2ft, 3ft, 4ft, 5ft, 6ft, 8ft. Generally, for the convenience of transportation, choosing a shorter size to splice is also a good choice.
Whether it is a corridor, a museum, a restaurant, or a kitchen, you can use this Up And Down Linear Lights to light up.
