EnVibe’s in-the-field rotating equipment vibrational analysis expertise and experience was called upon after a client had two successive fan catastrophic failures in their cooling fan on their gas-fired generator. The client’s belt-driven, overhung fan shattered into many pieces due to unforeseen reasons. This particular fan’s vibration signature and reliability condition could not be assessed while in running state due to inaccessibility of positioning…
EnVibe’s commitment to the next generation of bright minds in engineering, technology and science is evident: The Furious Falcons of Foster High School in Richmond, TX would love to thank EnVibe for sponsorship of FIRST Team’s 4328 Robotic 2013 Competition! EnVibe’s sponsorship of this weekend’s competition (March 7-9) at George R. Brown Convention Center helped create The Furious Falcon’s Frisbees shooting robot by…
Summary: This article describes the limitations and pitfalls of single-channel data as opposed to dual-channel data in the analysis of a journal sleeve bearing. This article is concerned with the analysis of displacement data in mils peak to peak taken from a permanently installed multi-channel monitoring system. The proximity probes on a multi-stage compressor train are monitored weekly using a single-channel portable data…
Over a period of eight years, EnVibe’s reliability group developed a Vibration Survey and Condition Based Predictive Maintenance Program (PdM) for the ABC Foods Houston Plant. ABC personnel played an integral part in setting up the program and implementing the repair procedures when machinery faults were detected. Critical to the success of the program was that the maintenance and operations departments were on…
Summary – This article describes the effects and vibration responses when carbon seal rubs are experienced on a steam turbine and procedures for correction. EnVibe received a call concerning a steam turbine unit driving a 32 inch gas blower at a chemical plant. The turbine had just undergone a yearly PM, replacing the bearings and seals. When the unit was brought back on…
Over a period of five years, EnVibe’s Equipment Reliability Group developed a Vibration Survey and Condition-Based Predictive Maintenance Program for a large plant in the Houston area. In the following text, you will find two graphs which contain the overall vibration data from the entire period. Supporting data tables are found below each graph displaying the vibration levels from the five different units…
A few years ago I was scheduled to go offshore to a production platform in the Gulf of Mexico. The platform had some problems with their Turbine/Compressor train and my job was to find out what was wrong and see that the problem was solved. The platform is located 60 some miles off the coast of Louisiana over the Mississippi Canyon with multiple…
EnVibe is involved in many different industries ranging from industrial to medical, onshore/offshore platforms — the list is long. In the Plastics Industry, we are involved with the entire range — from the source of raw material to the final making of plastic containers. In this video clip is a customer of ours that makes Plastic Bottles, a large variety of bottles. Most…
Part of what makes my job so fascinating is all the diverse industries we perform vibration analysis of machinery in. Take, in this case, a steel plant that makes plate steel and large steel pipes. I was able to capture this video of the glowing yellow steel coming out of the furnace and going through the large rolls is interesting. It is impressive…
