Development of Lifting Force Measuring Device for Magnetic Yoke Magnetic Particle Inspection Machine

Magnetic particle flaw detection is an important nondestructive testing method,which has been widely used in production practice. The performance index of magnetic particle flaw detector is stable and meets the working requirements,which is the premise to ensure the accuracy and reliability of the test results. The most critical performance index of magnetic particle flaw detector is the magnetization ability of its magnetic yoke. At present,the frequently-used test method of magnetization ability is lifting force test. This paper,according to the lifting force definition of magnetic yoke magnetic particle inspection machine,make use of smart sensors and high-speed data acquisition technology,develop a kind of magnetic particle inspection machine lifting force measurement device,this device is simple,visual result,don’t have to use heavy lifting force measuring block,greatly improve the calibration efficiency,achieved good social benefits and economic benefits.
