Glass Industry

Background

Glass manufacturing relies on high-temperature, continuous processes involving melting furnaces, blowers, cooling fans, and exhaust systems. These machines operate under extreme heat, heavy vibration, and dusty environments created by silica and raw material handling. Mechanical deterioration—such as unbalance, fouling, or bearing wear—can quickly escalate into failures that interrupt furnace stability or forming line operation.

To maintain production quality and prevent costly shutdowns, early detection of vibration abnormalities is essential.

Diagnosis Process

Novaseer’s predictive maintenance system applies a standardized diagnostic method suited for all rotating equipment in glass plants:

Trend Monitoring

Abnormal increases in vibration or temperature were detected over time, especially during furnace load changes or cooling phase adjustments.

Waveform Evaluation

Waveforms showed distortion, impacts, or periodic disturbances—patterns commonly related to:

• High-temperature deformation
• Unbalance from dust buildup
• Looseness caused by thermal cycling
• Overstressed bearings

Spectrum Analysis

Frequency-domain analysis revealed:

• Elevated rotating-frequency amplitude (unbalance)
• Harmonics or sidebands (looseness/misalignment)
• Early bearing characteristic frequencies

These combined signatures triggered a diagnostic warning and recommended on-site inspection.

On-Site Inspection & Maintenance

Technicians typically discovered issues such as:

• Dust or particulate accumulation on impellers

• Structural looseness caused by thermal expansion and contraction

• Unbalance from uneven material buildup

• Misalignment due to continuous furnace heat exposure

• Early bearing degradation

Corrective actions generally included cleaning, tightening, balancing, and replacing worn components.

Before & After Comparison

Condition	Before Maintenance	After Maintenance
Vibration Trend	Rising or unstable	Stable and reduced
Waveform Shape	Distorted with impacts	Smooth and consistent
Spectrum	Strong rotating-frequency peaks	Lower amplitude, balanced

These improvements confirm the mechanical issue was successfully addressed.

ROI — Typical value delivered for glass industry equipment includes:

• Unplanned downtime avoided: 4–10 hours

Estimated average: ~6 hours

Early detection of abnormal equipment behavior allows plants to shift corrective actions into scheduled maintenance windows, reducing costly production interruptions.

• Maintenance time saved: 1–3 hours

Estimated average: ~2 hours

Technicians can locate failure points more quickly with system-assisted diagnostics, improving repair efficiency and reducing troubleshooting overhead.

• Secondary damage prevented: $3,000–$8,000

Estimated average: ~$8,000

Advanced warnings help avoid cascading failures—such as increased wear on drive components, overheating motors, or misalignment-related losses.

• Total estimated value: $20,000–$50,000+

Estimated average: ~$50,000

For critical assets (e.g., lehr drives, forming equipment, cold-end inspection lines), timely alerts significantly reduce the likelihood of catastrophic failures and extended downtime.

Customer Feedback

Glass manufacturers frequently report smoother operation, reduced vibration alarms, and improved stability of forming or cooling systems. Early warnings allow maintenance work to be completed during planned downtime instead of disrupting furnace or line operations.
