Variable frequency drives (VFDs) have become a preferred method of process control for electric motor driven equipment ranging from vertical water pumps to centrifugal air fans. The following is a basic discussion of risks of using a VFD with direct driven centrifugal fans and methods of mitigating those risks to maintain equipment reliability.

Many small gearboxes are considered to be replaceable but the downtime they cause cannot be replaced. Oftentimes these gearboxes, though small, are critical to an operation. For example, a breakdown in a conveyor gearbox, burnt out the conveyor belt and brought a large mining site to a halt at a cost of $21,000,000 USD. Learn what tools you can use to perform 2-minute visual checks and oil analysis that can give you information to stay on top of your equipment reliability and manage risk.

Triaxial accelerometers are a useful combination of three sensing pellets, each taken from a single-axis accelerometer and oriented in a new package to cover all three Euclidean axes, that can quickly evaluate a machine’s condition. Obtaining data from just a single measurement axis can certainly clue you into developing machine faults and their severity, but monitoring all three axes, especially at both ends of the machine, gives the clearest picture of overall machine health.
