Análisis de falla de una mordaza de prensa de banco, tornillo elevador y tubo de transporte de amoniaco

Abstract

In this project the diagnosis of the faults that were presented in a vice for the bench press, a lifting screw and a transport tube for ammonia was made. To do this, a visual inspection of the object of study was carried out, with the support of characterization techniques such as optical microscopy and hardness measurement. The analyzes of the samples help to gather evidence to clarify the general panorama of the root of the fault. After studying the information collected, it is concluded that the gag was due to fatigue and that it shows a series of traces characteristic of this type of phenomenon. The steel screw is due to a bending stress causing a brittle fracture to occur. Finally, the tube for the transport of ammonia was due to corrosion in the form of bites caused by the environment to which it was exposed. This type of studies helps to define design parameters to avoid faults in machines and structures, as well as create a history of failures with defined causes that serve as support for future projects
