Machinery Applications Include: Electric Motors, Steam Turbines, Expanders, Compressors, Blowers, Fans, Pumps, Positive Displacement Compressors, Gears, Speed Changers, Journal Bearings, Radial Vibration, Thrust, Vibration Monitoring, Protection System, VMS, API 670.
Large Critical Machines exist in all industries including HPI, Chemical, Pipeline, Power Generation, Pulp and Paper and Water Treatment. Critical Machines are defined by the following criteria; criticality to production, capital cost, replacement cost and safety. As they may be only partially spared or not spared at all production will be lost if they fail. As Critical Machines tend to be high horsepower and heavily loaded Journal or Smooth Bore Bearings are most often used.
As most Critical Machines have already been supplied with Protection Systems many of which are or becoming obsolete a replacement systems can be modeled after the existing systems hardware. The following will help you insure that the system being provided for new or replacement vibration monitoring systems meets the intent of API-670.
Critical Machines or Critical Machine Trains are made up of many combinations of Drivers, Speed Changers and Driven Equipment. An all-inclusive Vibration Monitoring System can be ascertained by looking at the requirements for each machine component (case) individually and summing them together for a complete system.
