PAINT CIRCULATION SYSTEM

摘要

A paint circulation system includes: a main line; a branch line; a supply pump; and a pressurization device for storing pressure of the paint in a high-pressure state in which the pressure of the paint is higher than a predetermined pressure, and for applying pressure to the paint inside of the branch line in a low-pressure state in which the pressure of the paint is lower than the predetermined pressure, in which sedimentation of the paint is prevented by driving the supply pump so that the high-pressure state and the low-pressure state occur, to cause flow sending the paint inside of the branch line from a side of the painting device to a side of the main line using a pressure difference between the predetermined pressure in the low-pressure state and the pressure of the paint.

1. A paint circulation system for supplying paint from a paint tank to a painting means, comprising:
a loop-like main line in which the paint is supplied from the paint tank; a branch line that branches from the main line, and is connected to the painting means; a supply pump that pressure-feeds the paint supplied to the main line to a side of the painting means; and a pressurization means for storing pressure of the paint in a high-pressure state in which the pressure of the paint pressure fed by the supply pump is higher than a predetermined pressure, and for applying pressure to the paint inside of the branch line in a low-pressure state in which the pressure of the paint is lower than the predetermined pressure, wherein sedimentation of the paint is prevented by driving the supply pump so that the high-pressure state and the low-pressure state occur, to cause flow sending the paint inside of the branch line from a side of the painting means to a side of the main line using a pressure difference in the low-pressure state.
