Zhongyun Technology's Intelligent Operations and Maintenance Platform Empowers Food Enterprises—Successfully Addressing Resonance Faults in Water-Cooled Chillers to Ensure Continuous Production.

Recently, a well-known food enterprise leveraged the intelligent operation and maintenance platform provided by Wuhan Zhongyun Kangchong Technology Co., Ltd. (hereinafter referred to as "Zhongyun Technology") to accurately predict and efficiently address a motor resonance issue in the water-cooled chiller equipment. By implementing targeted welding reinforcement measures, the equipment's vibration levels were restored to normal without disrupting core production processes. This incident clearly highlights the platform's critical role in predictive maintenance for equipment within the food industry.

I. Real-time Monitoring and Early Warning to Detect Equipment Anomalies

As a core production component in the food industry, water-cooled chillers play a critical role in maintaining stable production temperatures. Any equipment malfunction can directly impact food fermentation efficiency and product quality. Traditional manual inspections are often unable to detect real-time anomalies in equipment performance. However, Wuhan Zhongyun Kangchong's intelligent operation and maintenance platform addresses this challenge by deploying high-precision sensors at key monitoring points of the equipment, enabling 24-hour uninterrupted data collection and dynamic monitoring.

When the equipment was powered on and started operating in June, the system platform detected abnormal vibration data at the motor drive end: the maximum vibration velocity in the horizontal direction reached 14 mm/s, exceeding the system's preset threshold. This triggered a fixed-threshold alarm generated by the platform, which simultaneously issued a notification stating " Acceleration waveform imbalance or foundation loosening "Mechanism alarm information. The platform's alarm messages clearly indicate: the alarmed device, alarm measurement point, alarm content, actual value/alarm threshold, alarm level, initial alarm time, and latest alarm time, providing the operations and maintenance team with clear risk guidance."

II. Precise Data Diagnosis to Identify the Root Cause of the Fault

After receiving the alert, the Zhongyun Technology diagnostic team conducted an in-depth analysis of the vibration data from the motor drive end. By examining the spectrum analysis and correlating it with the equipment's operational structure and the motor's rated speed, they ruled out the possibility of a simple bearing failure. Instead, the preliminary assessment identified the root cause of the issue as either "resonance within the motor or loosening of the foundation."

Diagnostic Conclusion: The motor of the water-cooled chiller unit is operating in a warning state, with the core issues being resonance or foundation loosening.

Maintenance Recommendations: Strengthen equipment operation monitoring. During shutdowns, prioritize inspecting whether the motor foundation platform is loose. If no obvious loosening is detected, welding reinforcement should be performed on the foundation platform.

III. Implement closed-loop management to ensure stable production.

The platform operates a closed-loop process encompassing "early warning, diagnosis, handling, and verification," ensuring efficient fault resolution and controllable outcomes.

1. Planned shutdown management for precise problem resolution

The company, following the diagnostic recommendations, scheduled equipment shutdown for inspection on September 4, 2025. On-site verification confirmed that the motor equipment's steel structure platform was experiencing resonance issues. Consistent with the platform's diagnostic conclusion. ). On-site maintenance personnel immediately carried out welding reinforcement work on the channel steel and patterned plates of the steel platform. The entire process did not interfere with the core fermentation production period, effectively avoiding capacity losses caused by unplanned downtime.

2. Validate data effectiveness and restore equipment stability

Following the equipment restart on September 16, 2025, real-time monitoring on the platform indicates that the horizontal vibration velocity at the motor drive end has dropped below 2 mm/s. Additionally, the trends in horizontal, vertical, and axial velocities have all stabilized, confirming that the equipment has returned to normal operating conditions.

IV. Core Value of the Platform, Driving Industry Operations and Maintenance Upgrades

This case study on the water-cooled machine failure highlights the three core values of Zhongyun Technology's Intelligent Operations and Maintenance Monitoring Platform in the food industry:

1. Overcoming limitations in inspection: Replace manual periodic inspections with 24-hour real-time monitoring to precisely detect dynamic resonance anomalies during equipment startup, addressing the critical pain points of "difficult human detection and challenging fault prediction."

2. Reduce operational maintenance costs: By leveraging data-driven, precise diagnostics to directly pinpoint the core issue of "platform resonance," we can avoid unnecessary disassembly and repairs, shorten response times, and minimize equipment wear and tear.

3. Safeguarding Production Safety: Supporting enterprises in transitioning their equipment from "reactive maintenance" to "predictive maintenance," ensuring the stable operation of water chillers, and thereby providing reliable support for temperature control in fermentation processes, ultimately maintaining consistent product quality.

In the future, Zhongyun Technology will continue to iterate its equipment monitoring technologies and AI-based diagnostic algorithms, further expanding application scenarios into industries such as food and biomanufacturing. We will provide more enterprises with intelligent operation and maintenance solutions that deliver "precise early warnings, efficient responses, and stable assurance," thereby supporting high-quality industry development.
