荧光磁粉探伤检测系机电一体式结构。由电源控制系统、送料机构、复合磁化机构、磁悬液喷淋回收系统、转动观察系统、荧光灯系统、下料退磁机构等组成。专门以湿式磁粉法探伤检测接箍类等环型件的表面、近表面的各种裂纹和细微缺陷。
Fluorescent magnetic particle inspection is an electromechanical integrated structure. It consists of a power supply control system, a feeding mechanism, a composite magnetization mechanism, a magnetic suspension spray recovery system, a rotation observation system, a fluorescent lamp system, a blanking demagnetization mechanism and the like. Wet magnetic particle inspection is specially used to detect various cracks and minor defects on the surface and near the surface of ring-shaped parts such as couplings.
控制电路采用可编程控制器PLC集中控制，具有手动控制和自动控制功能，手动控制时可进行设备的每个功能动作的手动操作控制，自动控制时设备自动执行PLC内部自动程序，实现送料→夹紧（穿棒）→喷淋→磁化（两次）→继续送料→转动机构上升→转动（观察）→旋转90℃→转动（观察）→下料退磁等一系列动作的半自动化控制,程序自动循环执行。在程序执行过程中如需立即结束，按动设备的复位按钮开关，程序立即结束，自动回到初始位置。
The control circuit adopts PLC centralized control with manual control and automatic control functions. During manual control, the manual operation control of each functional action of the equipment can be carried out. During automatic control, the equipment automatically executes the PLC internal automatic program to realize the semi-automatic control of a series of actions such as feeding → clamping (threading) → spraying → magnetization (twice) → continuous feeding → lifting of the rotating mechanism → rotation (observation) → rotation at 90℃→ rotation (observation) → blanking demagnetization, and the program is automatically and circularly executed. If the program needs to be finished immediately during execution, press the reset button switch of the equipment, and the program will be finished immediately and automatically return to the initial position.
磁化电流采用可控硅无触点无极调压技术，交流磁化均带断电相位控制，既适合连续法又适合剩磁法探伤检查，复合磁化一次性显示全方位裂纹缺陷，使用更安全方便。
Magnetization current adopts SCR contactless stepless voltage regulation technology, AC magnetization is controlled with power-off phase, which is suitable for both continuous and remanence flaw detection. Composite magnetization displays omnidirectional crack defects at one time, and is safer and more convenient to use.
