TUBE CLEANING METHODS AND APPARATUS |
摘要 |
Techniques for cleaning the inside of complexly-bent tubing are disclosed using a combination of minimal amounts of solvent and pneumatically propelled foam pellets. In order to increase device efficiency, an escapement apparatus employs a vacuum-assisted loading mechanism and retaining pin to reliably load one pellet at a time. |
