Abstract: A hydrocyclone vibration measurement system includes an upper vibration sensor attached to the overflow of a hydrocyclone and a lower vibration sensor attached to the underflow of the hydrocyclone. A vibration analysis system includes an ADC, an overall vibration value processing channel, and one or more band pass filters. The overall vibration value processing channel generates overflow and underflow scalar vibration values representing overall vibration measured at the overflow and underflow portions of the hydrocyclone. The vibration analysis system may interface with a DCS to provide control information for controlling the hydrocyclone based on the overflow and underflow scalar vibration values.

Abstract: A rotating machine valve health monitor. Aspects of the valve monitor include instrumenting each valve of a reciprocating compressor, or other rotating machine, with a sensor capable of detecting at least vibration and instrumenting the crank shaft with a sensor capable of detecting at least rotation. A controller directly monitors the operation and condition of each valve to precisely identify any individual valve exhibiting leakage issues rather than only identifying the region of the leakage. The valve monitor uses a relatively high frequency stress wave analysis technique to provide a good signal-to-noise ratio to identify impact events indicative of leakage. The valve monitor uses circular waveforms of vibration data for individual valves to identify leakage by pattern recognition or visual identification. The valve monitor provides ongoing data collection to give warning of predicted valve failure and scheduling of preventative maintenance for failing valves.
