Bearing wear triggers an alarm, and the Zhongyun platform provides precise location for rapid repair.

In compressed air systems, screw air compressors are the core equipment that ensures the stable operation of pneumatic devices. Recently, a screw air compressor at an industrial equipment company experienced a continuous increase in vibration acceleration during operation, triggering an alarm on the monitoring platform. Using advanced analytics, the Zhongyun Technology Intelligent Operations and Maintenance Platform accurately identified a potential bearing wear issue on the compressor’s non‑drive end, guiding the company to replace the bearing. As a result, the vibration levels quickly returned to normal, ensuring the safe supply of compressed air for production.

1. Acceleration continues to rise, and the platform triggers an alarm.

In early April 2026, the platform detected a sustained increase in the acceleration readings at the non-drive-end measurement point of the screw air compressor, triggering a trend‑alert on April 10. The system automatically dispatched equipment details, sensor locations, threshold‑exceeding data, and corresponding time stamps, ensuring that potential hazards are identified promptly.

II. Precisely Identifying Bearing Wear

The diagnostic team conducted an in-depth analysis of the vibration data and identified distinct impact events in the time-domain waveform, elevated background noise in the frequency spectrum, and evenly spaced frequency components, with clear characteristic frequencies. Based on this comprehensive assessment, bearing wear was diagnosed, and the company was advised to promptly shut down the equipment and inspect the bearing condition.

3. On-site bearing replacement resulted in a rapid reduction in vibration.

Based on the platform’s recommendations, the enterprise scheduled a shutdown for inspection on April 11 and confirmed significant wear on the non‑drive end bearing of the compressor, which was highly consistent with the diagnostic findings. Maintenance personnel replaced the worn bearing. Following the equipment’s restart, platform monitoring showed a marked reduction in vibration levels, and the unit resumed normal operation.

IV. Core Value: Enabling Bearings to “Retire Early”

The successful resolution of this air compressor bearing wear failure underscores the unique value of the Zhongyun Platform:

1. Trend Detection: Issue an early warning during the phase of continuously increasing acceleration to prevent sudden bearing failure and subsequent equipment damage.
2. Precise Diagnosis: Identify bearing faults through feature analysis, eliminating unnecessary disassembly and inspection and improving maintenance efficiency.
3. Rapid closed-loop response: From alarm to completion of the replacement, the entire process takes just one day, minimizing disruption to production gas supply.

Zhongyun Technology will continue to iteratively advance its intelligent diagnostic technologies, delivering end-to-end smart operations and maintenance solutions that provide “precise early warning, efficient response, and robust reliability” for industrial equipment, thereby helping enterprises fortify their equipment‑safety defenses.
