Turbo Pump Experiencing Imbalance Issues?

The most critical aspect of a Turbo Pump’s magnetic levitation bearings is dynamic balance. High rotational frequency fluctuations indicate poor balance. How can this be measured effectively?

Operating Principle of Turbo Pumps

A turbo pump operates by transferring kinetic energy to gas molecules through high-speed rotating blades, creating directional flow for vacuum pumping. Alternating rotor and stator blades are arranged in opposite inclined directions, forming multiple blade stages. Turbo pumps are generally classified into two main types based on structure: vertical type and horizontal type.

The vertical type is more compact than the horizontal type but is more susceptible to damage if foreign objects enter the pump, making repairs more challenging. It also has lower stability and is more prone to vibrations. However, it offers advantages such as replacing diffusion pumps and vacuum gauges, greater flexibility in vacuum system integration, and lower cost compared to horizontal pumps. Additionally, turbo pumps with magnetic levitation bearings are less affected by oil contamination.

Solution and Monitoring Explanation

IMS-TP Turbo Pump Inspection and Analysis System
Turbo pumps with magnetic levitation bearings exhibit lower vibration levels, requiring spectral analysis for accurate evaluation. One of the core issues with magnetic levitation bearings is dynamic balance—higher rotational frequency fluctuations indicate poor balance. We utilize a portable inspection and analysis system to ensure pump quality and implement predictive maintenance, preventing unexpected shutdowns.
