| Summary: | Many types of equipment today are required in
service well for 24 hours a day and beyond their intended
lifetimes. Then, to dismantle them for inspection from time to
time is very expensive while the owners need to consider all the
faults before making the decision. Therefore, vibration
signature is introduced to help the owners to decidebased on
all the relevant information taken. Vibration signature is an
essential tool to detect motor problems, which can identify the
specific faults like bearing or gears, or rotor imbalances
without interrupting the operation of the motor. The
techniques used in the vibration signature are field
measurement with portable instruments, field recording
followed by detailed analysis and permanent online
monitoring. Each iibration shows the different characteristic
that determined by the running speed, the number of poles on
the rotor, the numbers of slot in the rotor or statof, and other
variables. The objective of this project is to identify most of the
bearing defects during the operation and provide valnable
information to develop a maintenance schedule before the
motor breaks down. All in all, from all the infermation, the
owner can reduce the amount of unscheduled downtime while
extend the running time of the motor ana also decrease ebe
energy costs. |
