The extruder gearbox.

Early warning of bearing fault in extruder gear pump

Gear pumps are a vital component in extrusion polymer and plastics industries to maintain the steady flow and homogeneous material required for high-quality extruded products. This case study from an extruder application demonstrates the advantages of a multi-technique approach to provide maximum prewarning time on this critical piece of equipment.

When traditional vibration enveloping was used alongside SPM's patented HD technology on this four-stage gearbox with two intermediate shafts, the early-stage damage detection capability of SPM’s HD technologies and high-frequency condition monitoring techniques was clearly proven.
