On line fault diagnosis system for metallurgical casting crane

Generally speaking, mechanical equipment includes prime mover (such as motor), transmission system (such as gear transmission and hydraulic transmission) and execution system (mechanical functions or actions executed by the terminal). The structural forms of motor and gear transmission system are similar, but the scales are different. These two systems are also the most prone to failure. Therefore, there are many researches on fault diagnosis methods and principles. The functions of the execution system are different, and the fault forms are more diverse and often related to the process flow. Therefore, the fault diagnosis of the execution system is more personalized.

WT-W500YW on-line fault diagnosis system (motor, reducer, wheel)

Casting crane is a kind of special lifting equipment for super large production line, with large lifting capacity, long operation cycle, and poor operating conditions and environment. In use, it is difficult to find the problems of the motor, reducer and traveling wheel during the daily spot inspection, and the maintenance time is long after the fault occurs, resulting in large losses in unplanned shutdown.

The fault diagnosis system of metallurgical crane (motor, reducer and wheel) is based on the online monitoring of crane, matching the fault model of motor and reducer and big data trend analysis to realize the fault diagnosis of equipment. Provide timely guidance for the maintenance of motor, reducer and wheel.

Provide users with real-time status monitoring, alarm status, trend curve, historical data query and analysis, fault event record and information push of motor and reducer.
