LORD
balancing systems are designed to correct
unbalance in rotating machinery while they are
operating. Unlike traditional "off-line"
balancing techniques, which require the rotating
asset to be stopped and often disassembled while
corrections are made, LORD balancers monitor
rotating imbalance and provide real start-up and
shut-down cycles. These permanently installed
balancers are proven to reduce maintenance cost
and improve performance.
The balancer is installed permanently onto
the rotating shaft; sensors continuously monitor
the vibration levels while running. When an
increase in vibration is detected above a
pre-determined level, the controller initiates
an advisory message as to the change in state of
the unbalance. It then instructs the balancer to
make an automatic balance correction. Balance
adjustments can be made during start-up, normal
operation and shutdown.
The balancing systems provide the ability to
continuously monitor the state of balance of the
rotating system. Rather than “covering
up/masking,” a balance problem, the balancing
system continuously reports the state of the
system’s unbalance, thus providing diagnostic
information used to predict system health and
optimize service outages.
LORD balancers have been applied to fans,
pumps, turbines, generators, compressors,
grinders, lathes, spindles, drive shafts and
aircraft propellers.
