LORD Corporation USA
LORD balancing systems are designed to correct unbalance in rotating machinery while in operation. The system is comprised of five parts: the balancer, actuator coil, sensors, controller and software. Unlike traditional “off-line” balancing techniques, which require the rotating asset to be stopped while corrections are made, LORD balancers correct for unbalance while the rotating equipment is running.

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.
