Essential Capabilities Every Monitoring and Diagnostic System Must Have A Straightforward Guide to Extruder Train Diagnostics Monitoring takes place on the gearboxes of the extruder, melt pump (gear pump), pelletizer, dryer and associated motors. All critical bearings and gear wheels must be monitored to detect and identify impending failures at an early stage and avoid costly downtime. For this specialized application, there is no “one-system-fitsall” solution. Several factors make extruder train monitoring a unique challenge: • Variability in load and vibration amplitude due to process changes • Wide range of shaft speeds in gearboxes due to the many stages of gear reduction • High number of different faults to track in complex gearboxes • Variable-speed operation of the melt pump [...]
