ABSTRACT
Insurance based on the diagnostic process of any technical system be organizing its diagnosis through testing or operation. Non-destructive flaw allows detection efficiency defects, determining the nature and their parameters, ie the position, orientation and size for pieces or subassemblies belonging to coal preparation equipment. In this way can decide acceptance, remediation or refusal, in accordance with the criteria of admissibility of defects execution prescribed documentation (including norms and standards) and their causes can be identified and corrective action execution technology. Using phasor method of ultrasonic fault detection is a modern way to help locate and determine the orientation of the pieces of equipment defects grinding of coal because they depend on three-dimensional mobility and transducer device (no manual movement of the transducer). This paper treats aspects of using ultrasonic detector for detecting defects of type DGS 100 subassemblies of the mills to prevent accidents and increase the safety level of exploitation.
