Using technical assessment to identify root cause

A large pulp mill was shut down due to failure of the forced draft fan on its recovery boiler. Excessive vibration of the inboard bearing had broken the cooling water line inside the oil-filled bearing housing and flushed out the oil. The bearing journal had overheated, cracked and melted the Babbitt causing heavy scouring damage to the shaft surface.

10 benefits of using adjustable speed drives

Adjustable speed drives can be used in most applications where motors power mechanical equipment. Drives provide precise electrical motor control, enabling motor speeds to be ramped up and down or maintained at a required speed. The obvious benefit is the motor and drive use only the require amount of energy, rather than having a motor run at a fixed speed.
