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 lifting force of magnet yoke type flaw detector, which comprises the following steps: S1, material selection: taking a to-be-tested workpiece with a regular surface; s2, checking: checking whether dust, oil stains, scrap iron and rust spots exist on the surface of the workpiece or not, starting a centrifugal pump of the magnet yoke type flaw detector, uniformly stirring the magnetic suspension, checking whether the magnetic suspension exceeds the service life or not, and if yes, replacing the magnetic suspension; s3, brushing: specifically, brushingdust on the surface of the workpiece, and flushing and washing the surface of the workpiece with clean water added with detergent. According to the method, the sysmatic step includes that a flaw detection process of the magnet yoke type flaw detector is planned into steps; lifting force tests are carried out on three kinds of workpieces with different weights of 4.6 kg, 18.1 kg and 12.1 kg through a magnet yoke type flaw detector, and the obtained values are averaged; the lifting force of the magnet yoke type flaw detector is measured accurately, workers can detect proper workpieces conveniently according to the specific lifting force, the steps are clear and simple, and 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 ...
