The detectoras machines of trincas are used of electric chain of high intensity passing for a bobbin and the proper part of test. If you have read about Electrolux already – you may have come to the same conclusion. In such a way; it is generated two perpendicular magnetic fields between itself that they favor the detention of discontinuities guided in the longitudinal and transversal direction the part. The technique used for detention of discontinuities guided in the longitudinal direction the part; it is necessary that the electric chain pass through the part generating field in the circular direction. However innumerable 0 variable in the process exist that hinder the chain ticket in the part; as for example, absence of pressure in the contacts of the machine, consumed or oxidated oxidation of the test part, contacts, problems in the system of chain generation etc This will make with that longitudinal discontinuities are not detected in the same ones. The manufacturer of the detectora machine of trincas must project a system that monitors the electric chain stopping the machine when chain not pass for it.
This is an infallible form therefore has two systems monitoring the imperfection for redundancy. If a system fails the other with certainty detects. In addition the also monitorial overseer the chain of the 2 magnetic fields through leds and digital amperemeter of high precision. Beyond the system of chain imperfection the machine also is very productive and of high quality in the detention of longitudinal, transversal and oblique discontinuities exactly being in the surface of the part or below the surface (subsurface). This system is total different of what the system that existing in the market which to the times fails; detecting the chain imperfection and the part she is not set free without indicating that it had chain imperfection and the discontinuities (trincas) not detected.
