(1) Sensory identification method: Without using tools and instruments, the judgement personnel's experience and senses are used to judge the technical status of parts. Such as parts of cracks, breaks, bending, twisting, corrosion, fatigue erosion, etc., can be visually identified; parts of the connection is tight, the part itself is a crack, etc., can be tapped with a small hammer, with and out of voice voicing With the ear to identify; some parts of the crack can be smeared with oil after immersion in oil, and then tapped with a small hammer to identify whether there is oil ooze; can also shake the matching parts by hand, initially identified with the size of the gap.
(2) Measuring and appraising and appraising: Various measuring tools are used to check the fit size, clearance, surface shape and position deviation of the parts, which is a relatively accurate identification method. Commonly used measuring tools include rulers, strip rulers, calipers, gauges, vernier calipers, percent rulers, and dial gauges.
(3) Sample inspection and identification method: First, a standard model is produced according to the technical requirements. When the identification is performed, only the part to be identified is compared with the template to see whether the deviation is within the allowable range. This method is simple and practical.
(4) Special instrument inspection and identification method: if the magnetic flaw detector is used to inspect the internal cracks or voids of the parts; use the water pressure tester to check the sealing performance of the container; check the elastic state of the spring with the spring elasticity tester; check with the static or dynamic balance test stand Turning parts are balanced etc.
(5) No dismantling identification method: It is the various parts in the assembly conditions, the use of tools or other instruments, measuring its various horizontal or vertical or oblique distance with the nearby parts, or check the sealing, straightness or fit clearance Size, to determine whether the parts work well.
