Installations in MENA region

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 shut-down.

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.

LORD RealTime Fan Balancing Systems

LORD Fab Balancing Systems are comprised of sensors, a controller, and one or more balancers that make trim balance corrections to reduce fan vibration while the fan is still running, at any operating speed or load. The system is able to compensate for variable balance conditions due to material build-up, temperature variations and changing process conditions. Balance corrections are made automatically or manually, minimizing vibrations caused by unbalance in seconds.

How RealTime Fan Balancing Systems Work:

One or more balancers is permanently fixed on the rotating shaft, and each balancer is surrounded by a stationary coil used to transmit power into the balancer(s)
Balance corrections are made based on "Sense, then Adjust":
Sensors monitor vibration levels and transmit information to the controller
- When vibration exceeds a preset high limit or alarm, the controller signals the coil(s) to pulse power to the balancer(s) to make a balance correction
- The correction is made by repositioning the two counterweighted rotors relative to each other, located inside the rotating balancer(s)
- Vibration levels are reduced as the rotors are moved until the controller senses that vibration levels have dropped below a preset low limit
- The rotors are repositioned in seconds to complete the trim balance balance correction while the fan continues operating without a forced shutdown
- The system monitors and controls 1X (sha
