Maintenance of induction melting furnace is static first, then dynamic

The so-called static inspection refers to the inspection performed before the induction melting furnace is powered on. When it is confirmed that the static inspection is correct, the dynamic inspection can be performed only when the power is turned on. If abnormal conditions such as smoke or flicker are found, shut it down quickly and perform static inspection again. This can avoid energizing the induction melting furnace when the situation is unknown, causing undue damage.

As far as the measuring instruments and meters used in the current maintenance are concerned, only the functional online test and static characteristic analysis of the components on the circuit board can be performed. Whether the failed circuit board is finally completely repaired, it must be installed back to the original circuit for inspection Just work. In order to obtain the correct result of this inspection process to determine whether the circuit board with the replaced electrical and electronic components is repaired, first check whether the auxiliary power supply of the induction melting furnace is correctly supplied to the relevant circuit board as required, and the circuit board Whether each interface plug-in is plugged in reliably. And to eliminate the influence of the circuit board peripheral circuit failure, in order to correctly guide the maintenance work.
