Problems solved by technology

[0003] The existing yoke-type flaw detector needs to confirm the lifting force of the machine equipment when using it, so as to facilitate the subsequent lifting and flaw detection of the workpiece. The general lifting force measurement is more troublesome. Therefore, a lifting force test of the yoke-type flaw detector is proposed. method

Abstract

The invention discloses a method for testing the lifting force of a yoke type flaw detector, which comprises the following steps: S1, material selection, taking a workpiece to be tested with a regular surface; S2, checking, checking whether there is dust, oil, iron filings, rust spots on the surface of the workpiece , Turn on the centrifugal pump of the yoke flaw detector, stir the magnetic suspension, check whether the magnetic suspension has exceeded the service life, and replace it if it exceeds; S3, brush, brush the dust on the surface of the workpiece, rinse and scrub with clean water added with detergent The surface of the workpiece; the present invention plans the flaw detection process of the yoke flaw detector into steps through systematic steps, and carries out the lifting force test on workpieces with three different weights of 4.6 kilograms, 18.1 kilograms and 12.1 kilograms through the yoke flaw detector. And the obtained value is averaged, so as to test a more accurate and precise lifting force of the yoke flaw detector, and then facilitate the staff to detect the appropriate workpiece according to the specific lifting force. The steps are clear and simple, and the data is accurate.

Description

technical field [0001] The invention relates to the technical field of numerical detection, in particular to a method for testing the lifting force of a yoke-type flaw detector. Background technique [0002] The flaw detector is generally non-destructive flaw detection. The flaw detector is specially used for shipbuilding, petroleum, chemical industry, machinery, aerospace, transportation and construction and other industrial sectors to check the welding quality of materials and parts such as hulls, pipelines, high-pressure vessels, boilers, aircraft, vehicles and bridges. , and the quality of various light metal, rubber, ceramic and other processed parts. It is used to show the surface and internal defects of parts and welds processed from materials to evaluate the quality of products. Shows the location, shape and size of the discontinuity. It can detect extremely fine cracks, hairlines, white spots, folds, inclusions and other defects on the surface of the material. It ...
