Rotating Equipment Monitoring and Diagnostic Technology

On-site and Remote Vibration Monitoring and Fault Diagnosis for Rotating Equipment

Vibration issues in critical rotating machinery are among the most common and complex challenges in plant operations, significantly impacting both equipment safety and the economic performance of enterprises. Our company has been engaged for over two decades in the research, development, and application of vibration monitoring, diagnosis, and predictive technologies for large-scale rotating equipment, accumulating extensive experience in fault diagnosis. The accuracy rates for identifying common faults and for vibration prediction both exceed 90%. In recent years, we have developed a “Remote Monitoring and Fault Diagnosis System for Large-Scale Rotating Equipment.”

On-site dynamic balancing of rotors

On-site rotor dynamic balancing is a technique that, without removing the equipment’s cover, addresses both the initial imbalance of rotating machinery rotors and imbalances that develop during operation by adding counterweights to the rotor. This method is convenient for field application; for rigid rotors, the typical job duration is 2–3 hours, while for flexible rotors, the time required depends on site-specific conditions. The company is equipped with the U.S.-made VB3000 on-site dynamic balancing system and a holographic on-site dynamic balancing system, which are used to perform on-site balancing for rigid and flexible rotors, respectively.

Vibration and Noise Assessment and Mitigation

During operation, mechanical equipment inevitably generates vibrations and noise of varying degrees. When operators work for extended periods in environments with high noise levels, their physical and mental health may be adversely affected; in severe cases, this can lead to occupational diseases. Vibration and noise assessment and control involve evaluating on-site measurement data against relevant vibration and noise standards and implementing appropriate mitigation measures for any non‑compliant findings, thereby bringing the levels within the permissible limits.

Wear Monitoring and Ferrography Analysis of Lubricating Oils

Ferrography is an oil‑analysis technique based on wear‑particle analysis, and it is one of the most effective methods for monitoring equipment wear conditions and diagnosing faults. Since the 1980s, our company has developed and applied this technology, achieving remarkable results in promptly predicting potential wear‑related failures, identifying the causes and locations of equipment malfunctions, providing reliable evidence for inspection and maintenance, and ensuring the safe operation of equipment.

Monitoring and analysis of flue gas dust concentration and particle size in flue gas turbines, etc.

Flue gas particulates are the primary factor affecting the long‑term operational reliability of the refinery’s draft fan–main air blower unit and even the entire catalytic cracking unit. When particulate concentration or particle size exceeds allowable limits, erosive wear on the rotor and uneven deposition (sintering) of particles on the rotor can lead to excessive vibration levels, resulting in unplanned shutdowns. By monitoring and analyzing these parameters, it is possible to promptly assess the efficiency of the three‑stage cyclone separator and the overall process conditions, enabling targeted measures to reduce particulate concentration and particle size, or to adjust the opening of the draft fan inlet butterfly valve, thereby preventing excessive erosion of the rotor and avoiding unscheduled outages.

Lubricant Particle Size Analysis

Lubricant particle‑size analysis is an oil cleanliness‑assessment technique based on light‑obscuration laser‑based automated particle counting. It provides rapid and accurate characterization of the size distribution and concentration of solid particulate contaminants in lubricants, enabling determination of whether the equipment’s lubricant meets specified cleanliness standards. It is also one of the fastest and most effective methods for monitoring equipment wear and diagnosing faults.
