nov 14, 2016 the motor tripped on high vibration at one of its bearings. initially, only one vertical probe reached the trip value, and the second one didnt. after seconds, both probes reached the trip value of 7.1 mmsec, and the motor was shut down, exactly as intended. all bearings were deep-groove style 6317, meaning the bearing bore was mm.If the plant is manned by responsible operating staff on a continuous basis, the last four items can be monitored by supervisory equipment having preset alarm levels. this allows the operator freedom to manoeuvre the operating conditions to reduce the dangerous condition. If unable to do this, the operator must trip the plant manually.monitoring philosophy. within the lng industry as in all other industries, Br el & Kj vibro is completely focused on providing the necessary system, diagnosis and detailed supporting information necessary to help avoid unplanned machine downtime; no matter where the customer is located or what level of technical expertise and resources they have on-site.nov 07, 2019 but in this blog, thought would calibrate the vibration of weed, alcohol, and what is called plant medicine. just to be clear on the process that we are using for calibrating these different herbs or these different processes of fermentation or whatever it is, it has to do with understanding of book that is called power vs force, which has sep 17, 2013 resonant vibration in mechanical structures such as pumps, turbines and motors occurs when a natural frequency is at or close to a forcing frequency such as rotor speed. when present, this condition can cause severe vibration levels by amplifying small vibratory forces from machine operation. such problems often develop after a speed change has
auxiliary feedwater pumps automatically started in accordance with plant design upon trip of the main feedwater pump on low condenser vacuum. all safety systems responded per design and the plant was stabilized in mode cause OF event investigation into the event determined the high vibration experienced by the turbine was as a
