PLC控制等离子喷涂设备的研制

Development of PLC controlled plasma spray equipment

研制了以Ｆ１－４０ＭＲ为核心的可编程控制器（ＰＬＣ）控制的等离子喷涂设备．喷涂电源采用８０９８单片机控制，最大额定输出功率１２０ｋＷ，并利用维弧电源消除了高频对单片机系统的干扰．研制的大功率等离子喷涂枪结构合理，引弧容易，喷涂过程稳定，能适应各种合金粉末喷涂要求．试验结果表明，整体设备操作简单，运行可靠，喷涂效果较理想．

The PLC controlled plasma spray equipment using F1 40MR as its central unit is developed. The spraying power source is controlled by 8098 single chip micro computer and its rated maximum output is 120 kW.The pilot arc power source is also used to eliminate the interference on the single chip micro computer form high frequency igniter. The high power plasma spraying gun is reasonable in structure, easy in striking, stable in spraying process and suitable for various alloy powder. It is shown by test results that the equipment is convenient and reliable to operate, and its spraying result is ideal.
