Vibration Monitoring for the Paper Industry

Download the printer-friendly Vibration Monitoring for the Paper Industry Application Note

Predictive maintenance is essential to the paper and pulp manufacturing process to ensure product efficacy, operational uptime, and prevent catastrophic failure. Due to the intense heat and caustic processes involved in paper manufacturing, machine fires are a common occurrence in the absence of predictive maintenance.

Condition monitoring programs can be used to monitor the vibration of the bearings throughout the plant and improve the reliability of the overall process.

Commonly Monitored Machines within a paper mill include:

▶ Calendars
▶ Chippers
▶ Dryers
▶ Drying Cylinders
▶ Fans
▶ Gearboxes
▶ Motors
▶ Compressors
▶ Paper Machine Rolls
▶ Couch Rolls
▶ Pumps
▶ Winders

Common faults like misguided felts, breaks, and fires can be caused by defects in rolling element bearings resulting from:

▶ Improper Lubrication
▶ Misalignment
▶ Uneven Wear
▶ Overloading

Due to the often hot, wet, and chemically challenging environment present in paper and pulp processing, CTC recommends the permanent mounting of vibration sensors to the machine. CTC offers a variety of robust and reliable hardware tailored to meet the needs and environments of each industrial process within the paper industry.

When permanently mounting sensors, it is important to run cables back to a safe data collection point to limit analyst exposure to the high temperatures found in the dryer section. CTC Junction Boxes provide a common cable termination point for bringing compatible cables for sensors back to one location for routine data collection with portable data collectors.

CTC offers a wide variety of Junction Boxes ranging from 1 channel up to 48 channels. Multiple channel count configurations mean that you only pay for the number of channels that you require. Due to moisture ingress concerns in paper processing, CTC recommends only selecting enclosures with latching doors for a NEMA 4X (equivalent to IP66) rating.
