Sucker rod magnetic flux leakage detector is used for flaw detection of a large number of new and old sucker rod cracks (including fatigue cracks, stress corrosion cracks, etc.), inclusions, folding and other defects used in oil fields.
Nanjing BKN Automation System Co., Ltd. is headquartered in the beautiful ancient capital of China, Nanjing. It is a high-tech enterprise specializing in the development of non-destructive testing instruments and equipment. The company is committed to the development of eddy current, magnetic flux leakage and various non-standard equipment, and has a number of national patents independently researched and developed. Products are widely used in aerospace, military, automotive, electric power, railway, metallurgical machinery and other industries. Product exports: the United States, Russia, Germany, Singapore, Thailand, India, Hong Kong, South Africa, Taiwan, Vietnam, Kazakhstan, Iran, Japan, South Korea, Brazil.
Since the finished sucker rod has a pier head during flaw detection, it will inevitably generate a beating during the operation, and a beating interference signal will be generated. Especially when the flaw detection is required for high precision, the impact of the jump disturbance on the detection result is more obvious, which seriously affects the flaw detection. The accuracy of the results. To this end, our company has specially designed a two-stage probe automatic floating tracking device to reduce the jitter disturbance to some extent. On this basis, we have developed a fully automatic roller avoidance technology. When the sucker rod head passes a certain roller, the roller automatically avoids it, completely avoiding the jump of the sucker rod head during operation. The reference ensures the stability and reliability of the test results.
Testing Φ16mm ~ 46mm sucker rod crack, eccentric wear and corrosion pit, using DC demagnetization and AC demagnetization, automatic detection, automatic alarm, automatic identification and automatic alarm.
