ACOUSTIC BEARING CHECKER

LOW SPEED

Low rotational speed of operation (as low as 0.1RPM)

LUBRICANT

Indicates lack of lubricant/dirty lubricant.

16-25__ALARM CONDITION
>26+___DANGER CONDITION

ASSIGNING PRIORITY LEVELS

GOOD CONDITION

___No abnormal trends or performance is noted at the time of data acquisition, thus no action is typically recommended at this time, and acquisition is scheduled for the next calendar date.

ACTION: No Action requires.

SUSPECT CONDITION

___Typically employed when a change in machine performance or mechanical wear mechanism is detected, however, trends need to be observed to determine if the machine stabilizes, or if operational methods are causing the excursion. It is recommended to be re-greased and lubrication oil change. Typically, measurement frequency is doubled during this period

ACTION: Re-greasing on Lubrication Oil change then re-inspection.

ALARM CONDITION

___Machinery data indicates operation is in the rough category. Plans should be made to arrange repair outage at first availability. Vibration, oil, temperature and operation data should be examined to determine dynamic data trends and root cause of problem. This allows for systemic failure repair (for example, bearings, lubrication, etc.), and allows source faults to be identified. Repairs and operational options (imbalance, misalignment, excessive machine speed, cooler problems, etc.) may be exercised to prolong machinery availability and minimize loss of production.

ACTION: - Apply FFT analysis to identify the problem.
_________- Prolong the machine by add grease or lubrication oil change.
_________- Using alternative CBM technique to trend the machine degradation.

DANGER CONDITION

___Machinery data indicates that failure is imminent. Machinery requires immediate attention, and the immediate repair shutdown should be seriously considered. During this level attention, the machine should be monitored a minimum of once per day.

ACTION: - Follow up inspection and trending more frequently.
_________- Apply FFT analysis to identify the problem.
_________- Predict and confirm by alternative technique.
_________- Prolong the machine and make maintenance plan.
