Abstract
Recently, the ministry of environment banned the use of the existing airless method using the spray in painting industrial facilities. Therefore, it is necessary to develop a pressure-roller attached to existing airless painting systems. The hole design of the SUS piping and drum-bases of pressure-rollers currently developed and sold have not been studied in detail, so their efficiency is questionable. In particular, if sufficient paint is not supplied to both ends of the roller, it is necessary to rework with a brush after painting. Therefore, the holes of the drum base need to be distributed so that the paint can flow to both ends of the roller. In this study, numerical analysis was performed to determine the effects of the hole design in the SUS piping and drum-base on the flow patterns of the paint and to suggest more efficient design measures. The analysis results showed that the uniform placement of the holes in the SUS piping is good for the balanced inflow of the paint. For the drum-base, the paint can flow better into both ends of the roller when the holes are concentrated and machined on both ends of the drum-base.
