Do you know about the debugging of high frequency induction heating machine?

1. For the debugging of the circuit, we can first disconnect the high-voltage circuit, cut off the connection line between the low-voltage side of the anode transformer and the three-phase AC power supply, only connect the low-voltage circuit, and then connect three 220V bulbs to the three-wire disconnection head and prepare for insulation. Finally, we close the door of the equipment, connect the main gate of the power supply, open the waterway, and start debugging. When adjusting the voltage adjustment button of the three-phase AC, pay attention to observe the brightness of the three bulbs in the process of becoming the brightest. Is there regular variation. After turning on the cold water system, we turn on the voltage of the vacuum tube step by step to see if the buttons, indicator lights, voltmeter, etc. of the equipment are displayed normally. For the high-frequency induction heating machine that is used for the first time or has not been used for a long time, its vacuum tube must be preheated for 10 minutes in advance, and the main power supply can only be connected after half an hour. For equipment that is often powered on, it can be turned on. Use without preheating.

2. When testing the waterway, be sure to disconnect the power supply, first check whether the water pipes of each way are firmly connected, and then open the water valve to test. During the process of increasing water flow, observe whether the waterway in each place is There may be water leakage or water seepage.

3. When the control circuit is checked and energized normally, the protection circuit should be debugged. Reduce the water pressure, the water pressure relay is still operating normally, but all the indicator lights must be extinguished, and the indicator shows a zero state. Before the operation of the equipment, check whether the door is opened and closed in time. If there is a problem, the main circuit and heating circuit of the device will automatically stop. Check whether the protection function of the overcurrent relay is normal.

4. When the high-frequency induction heating machine is conducting the heating experiment, after all the preparations are completed, put the workpiece into the inductor, prepare for heating in strict accordance with the operation sequence in the manual, turn on the heating, and adjust the power of the equipment, Anode voltage, etc., to see if the equipment can operate normally and the sensor is heating normally.
