The actual failure and treatment method of high frequency quenching equipment
1. Short circuit alarm and electrical parameter alarm sensitivity of high frequency quenching equipment.
Treatment method: short circuit alarm to check the circuit board, if the circuit board is found to be broken, replace the circuit board. Electrical parameter sensitivity alarm problem, optimize the program.
2. The problem of short circuit alarm and electrical parameter alarm of high frequency quenching equipment.
Treatment method: After inspection, it is found that the short-circuit alarm works normally. Electric parameter alarm problem, because this function is not turned on on the touch screen, there is no electric parameter alarm function. After turning on the function, it works fine.
3. Short circuit alarm failure of high frequency quenching equipment.
Treatment method: Check the short circuit circuit board, if the circuit board is faulty, replace the circuit board. Electrical parameter sensitivity alarm problem, optimize the program.
4. The electrical parameter alarm and short-circuit alarm of the new blind hole in the high-frequency quenching equipment.
Solution: Electric parameter alarm function, re-write the program. For short-circuit alarm problems, check the short-circuit alarm circuit board and replace the circuit board (during the replacement process of the short-circuit alarm device, it was found that the interfaces of the short-circuit alarm device were not uniform, and the devices could not be replaced as a whole, extending the equipment maintenance time). During the maintenance of the equipment, new blind holes were found, the filament voltmeter was broken (no variable output), and the buzzer of the three-color alarm light was faulty. Since there were no spare parts, it could not be replaced.
