维修中频感应熔化炉正确的询问过程及方法

从维修中频感应熔化炉的经验来看，与强电相关的器件、大功率器件，电源部分及相应的驱动部分电路损坏频率较高，也会出现各种各样的故障现象，表现与其相应的电子电路有关。中频感应熔化炉的维修过程就是寻找相应故障点的过程。在维修过程中应该坚持以人为主、设备为辅的原则，充分发挥人的主观能动性，降低维修成本，从故障现象人手，分析电路原理、时序关系、工作过程，找出各种可能存在的故障点，然后借助一些维修检测设备，确定故障点，确定故障元器件，然后寻找相应的元器件进行替换，使设备恢复其固有的一性能指标，中频感应熔化炉维修过程包括以下儿个方面。

(l)询问用户中频感应熔化炉的故障现象，包括故障发生前后外部环境的变化，如电源的异常波动、负载的变化等。

(2)根据用户自勺故障描述，分析可能造成此类故障的原因。

(3)打开出现故障的中频感应熔化炉外壳，确认被维修中频感应熔化炉的程序，分析维修恢复的可行性。

(4)根据被损坏元器件的工作位置，通过分析电路工作原理，从中找出损坏元器件的原因，以及一些相关的电子电路。

(5)寻找相关的元器件进行替换。

(6)在确定所有可能造成故障的原因都排除的情况下，通电进行测试，在做这一步时候，一般要求所有的外部条件都必须具备，并且不会使故障进一步扩大。

(7)在中频感应熔化炉工作正常的情况下，可以进行中频感应熔化炉的系统调试。

Correct inquiry process and method for repairing intermediate frequency induction melting furnace

The failure of the intermediate frequency induction melting furnace may be just an electrical and electronic component. The most important thing for the maintenance personnel is to find the electrical and electronic components that have failed. It is necessary to carry out inspection and measurement and make a comprehensive analysis to make a judgment. Handle faults and minimize useless disassembly, especially to minimize the number of soldering irons used.

In addition to experience, it is necessary to have the correct inspection method. The correct method can help the maintenance personnel to narrow the scope of detection from the inside and the inside, from the complex to the simple, and finally find the fault and repair it properly.

From the experience of repairing the intermediate frequency induction melting furnace , the high-power devices, high-power devices, power supply parts and corresponding drive parts have higher damage frequency, and various fault phenomena appear. Related to electronic circuits. The maintenance process of the intermediate frequency induction melting furnace is the process of finding the corresponding fault point. In the maintenance process, we should adhere to the principle of taking people as the mainstay and equipment as the supplement, giving full play to people's subjective initiative, reducing maintenance costs, analyzing the circuit principle, timing relationship, and work process from fault phenomenon personnel, and finding out various possible faults. Point, and then with some maintenance testing equipment, determine the fault point, determine the faulty components, and then find the corresponding components to replace, so that the equipment restores its inherent performance indicators, the intermediate frequency induction melting furnace repair process includes the following aspects.

(l) Inquire about the fault phenomenon of the user's intermediate frequency induction melting furnace , including changes in the external environment before and after the fault occurs, such as abnormal fluctuations of the power supply and changes in the load.

(2) Analyze the cause of such failure according to the user's self-discovery fault description.

(3) Open the faulty intermediate frequency induction melting furnace casing, confirm the procedure of repairing the intermediate frequency induction melting furnace , and analyze the feasibility of maintenance recovery.

(4) According to the working position of the damaged component, analyze the working principle of the circuit, find out the cause of the damaged component, and some related electronic circuits.

(5) Find related components for replacement.

(6) In the case of determining that all possible causes of the fault are eliminated, the power is tested. When doing this step, all external conditions are generally required and the fault is not further expanded.

(7) at medium frequency induction melting furnace normal conditions of work, it can be medium frequency induction melting furnace system debugging.
