Overview PdM specialists were requested to assess the vibratory movement of the blower and determine the source(s) of the unusual vibration and noise during equipment operation. The equipment had recently been aligned and to further diagnose faults Motion...
Overview The Ripsaw has had high vibration on the Arbor Jackshaft, and Motors for some time. The majority of the vibration on the arbor jackshaft and drive motors has been at the speed of the arbor, and not the speed of the motors, indicating structural stiffness...
Overview PdM was called on site to investigate the misalignment of the pump. Cross phase analysis was conducted along the base of the machine's platform. 180 degree phase difference was found, causing a momentary misalignment between the sheaves. The primary source of...
Overview PdM was called on site to investigate the root cause of excess vibration on the motor end of the compressor and skid. Cross phase analysis was conducted along the base of the machine's platform. 180 degrees phase difference was found in the vertical direction...
PdM Specialists was brought on site to investigate repetitive failures of a waste heat exhaust fan for a gas turbine. Vibration readings taken on the motor and fan bearings did not produce any conclusive leads. Motion Amplification to the Rescue!! Recordings were...
A centrifugal pump was investigated due to multiple seal failures. Vibration measurements indicated a misalignment condition, however, a precision alignment between the motor and pump had been performed and confirmed to be within tolerance. Motion Amplification to the...
