Digital portable type magnetic powder flaw detector

Abstract

The invention discloses a digital portable type magnetic powder flaw detector. The digital portable type magnetic powder flaw detector comprises a magnetic yoke and an instrument box, wherein an annularly arranged light emitting diode is arranged on the end face on the top of the magnetic yoke; a camera is arranged in the center of the end face on the top of the magnetic yoke; a logical control arithmetic unit and a microprocessing unit are also arranged in the instrument box; an external interface group is also arranged on the shell of the instrument box; and a microprocessor is connected with the external interface group through an interface circuit. The invention has the benefits that 1, the digital portable type magnetic powder flaw detector has digital advantages of storing on-site flaw detection result data, printing a flaw detection report by a printing machine, transmitting data stored in the flaw detector to a computer and recording and replaying the flaw detection process for continuous research and processing; 2, the digital portable type magnetic powder flaw detector has the miniaturization characteristic, light weight and portability; and 3, the digital portable type magnetic powder flaw detector has flexibility and convenience, wherein an internal battery is provided, so the instrument can work continuously for more than 3 hours without alternating current power supply.

Description

technical field [0001] The invention relates to a digital portable magnetic particle flaw detector. Background technique [0002] Among the existing physical methods of nondestructive testing, magnetic particle testing is the most intuitive, simplest and most widely used testing method. Magnetic particle flaw detection is suitable for detecting cracks and subtle defects on the surface and near surface of various small and medium-sized parts caused by casting, quenching, processing, fatigue and other reasons by wet magnetic particle method. Type, widely used in railway, electric power, petroleum, petrochemical, chemical industry, metallurgy, machinery, shipbuilding, boiler pressure vessel, nuclear industry, aerospace and other industries. Due to the wide range of applications of magnetic particle flaw detection, and there are certain differences in the detection conditions and detection requirements in various fields, the current general-purpose magnetic particle flaw detect...

AI Technical Summary

Problems solved by technology

Due to the wide range of applications of magnetic particle flaw detection, and there are certain differences in the detection conditions and detection requirements in various fields, the current general-purpose magnetic particle flaw detectors have also exposed some weaknesses in the application of some special fields. It is not traceable, cannot be separated from the AC power supply, and cannot be portable; use a trolley to push the workpiece flaw detection work; although magnetic particle flaw detection is the most intuitive method, it can be difficult to use in some areas that require flaw detection
