TADS ( Rail rolling bearings' faults and acoustic diagnosis system) literacy

TADS ( Rail rolling bearings' faults and acoustic diagnosis system) Literacy - 2018 11 - 25 ( The bureau of qiqihar car depot) As is known to all, bearing is the key to the vehicle parts, bearing failure is one of the main fault source of train operation. In order to prevent burning shaft, shaft, cutting Co. has established the infrared temperature monitoring system for network, and achieved very good results. Infrared temperature monitoring system is based on the principle of infrared radiation, for truck bearing temperature test online. But for truck bearing early failures, and there is no heat, no way. Every national railway found the hot box of rolling bearing fault, a lot of threats to transportation security. And TADS is in the truck when the shaft bearing is not hot can diagnose the fault, do bearing failure early detection, early warning, make the truck bearing failure of the protection barrier ahead of infrared forecast a stage. The complementary system and infrared temperature monitoring system, may carry on the forecast of bearing fault, greatly improving the accuracy and somewhat better than hot, provide reliable guarantee for transportation safety. TADS by acoustic diagnosis technology and computer network technology, through to the truck in the operation of the bearing noise signal acquisition and analysis, identify bearing working condition, can provide effective bearing internal early fault diagnosis results, fault found in hot shaft before. Combined with infrared axle temperature detection system, can more effectively prevent the cutting axis and derailment accidents, improve the level of bearing failure of protection, the column test to examine the rolling bearing, mainly from people sentenced to gradually transition to the man-machine combination, machine to give priority to the stage. TADS enhances the bearing ability of early warning, to prevent the reach mark, embodies the safety of 'prevention first' guiding ideology, to ensure driving safety.
