Cleaning By Internal Penetration of Parts
Bearing Cleaning Demonstrates the Power of VCN
Similar to the initial vapor bubble nucleation observed in a boiling liquid, Vacuum Cycling Nucleation (VCN) bubbles predominantly develop in confined regions, such as crevices within the vessel where phase change initiates. These vapor bubbles facilitate fluid and contaminant removal via expulsion during growth, while subsequent bubble collapse induces fluid influx. The cycle occurs on a timescale of seconds, ensuring rapid fluid exchange on internal surfaces. The turbulence generated during vapor formation enhances particle dislodgement and surface contaminant removal.
1. Secure all components. The VCN pressure maintains a uniform distribution across the chamber, including adjacent surfaces.
2. Perform cleaning at reduced temperatures when handling materials with heightened sensitivity.
3. Perform cleaning within a controlled environment, isolating from ambient conditions.
4. Perform vacuum drying to prevent spotting. Optimize solvent retention or decrease surfactant concentrations to achieve cost efficiency.
5. Conduct vacuum distillation to concentrate waste streams and facilitate solvent recycling, thereby optimizing operational efficiency and reducing costs.
Bearing Cleaning Demonstrates the Power of VCN
The video illustrates the application of Vacuum Cycling Nucleation (VCN) in inducing vapor bubble formation within micro-scale geometries. This process enables the cleaning, sterilization, and drying of devices that were previously difficult to sanitize via conventional methods. When operated at low vacuum levels or reduced temperatures, VCN allows precise identification of primary vapor nucleation sites within a component.
