Unbalance, misalignment, bearing failures, gear faults, motor electrical problems, etc. are typical faults experienced in all equipment. Identification and elimination of these faults and other issues are critical to maintaining the health of your plant equipment. Healthy equipment means lower maintenance cost, increased uptime, better product quality and a safer work environment for employees. This [...]

Lines of resolution (LOR) describes the number of lines of information that appear in the spectrum (FFT) acquired by the vibration data collector.  LOR can be calculated by dividing the overall frequency range collected (Fmax) by the number of lines selected.    LOR represent the amount of detail in the collected data.  Without sufficient detail in [...]

UPSTREAM PUMPING SOLUTIONS • Spring 2011 Mud Pump Vibration Analysis Online condition monitoring for hard-to-reach or hazardous places A mud pump is a reciprocating piston/plunger device designed to circulate drilling fluid under high pressure down the drill string and back up the annulus. Mud pumps come in a variety of sizes and configurations, but for [...]

June 2011 • RELIABLE PLANT A VIBXPERT vibration data collector was used to collect data on a DDM 750 AC 1M drilling machine at the workshop to check for factory acceptance. The VIBXPERT allows for high-resolution time signal and spectrum measurements to be collected. The VIBXPERT can collect more than 100,000 lines of resolution, which [...]

June/July 2011 • UPTIME Analyzing only vibration response spectra is difficult since they often don’t clearly match wall chart and textbook examples. As anyone who has practiced vibration analysis knows, vibration signatures obtained on routes are often far from the wall chart examples. The reason for this is that the vibration signatures collected and analyzed represent [...]
