OSCILLATION MONITOR FOR PULVERIZER JOURNAL ASSEMBLY |
摘要 |
A pulverizer 10 includes a journal assembly 19 with a grinding roller 18 that grinds solids in a grinding table 14. The oscillations of the journal assembly 19 are monitored by an angular displacement transducer (ADT) 32 that creates a composite signal. A controller 83 receives the composite signal from the ADT and compares it with known information of the pulverizer 10. It then identifies abnormal situations such as damage to a grinding roll 14, the grinding table 14, the spring assembly 20 and other parts of the pulverizer 10 before they cause major damage. |

1. A method of identifying potential problems of a pulverizer comprising the steps of:
providing a pulverizer housing with a rotatable shaft, a grinding table mounted on the rotatable shaft, at least one journal assembly pivotally mounted on the pulverizer housing, a grinding roll coupled to the at least one journal assembly, a spring assembly mounted on the pulverizer housing; providing an angular displacement transducer (ADT) coupled to the journal assembly by a coupling and a coupling adapter, with the ADT, coupling and coupling adapter each supported by a mounting bracket for ADT measurement of angular displacement of the journal assembly and electronic signal generation corresponding to the measurement of angular displacement; acquiring ADT measurement of angular displacement of the journal assembly over time; and generating an electronic signal indicating a potential problem with the pulverizer when the measurement of angular displacement is abnormal. |
