Description

Technical Field

[0001] The utility model relates to the technical field of printing press moistening liquid, in particular to a moistening liquid vacuum degassing device. Background Art

[0002] Fountain solution, also known as wetting liquid, sink liquid, and fountain liquid, contains a wetting agent to change the surface tension of the printing plate surface. PREMIER FOUNT with added wetting control ingredients can also help reduce the amount of ink while obtaining clear dots and bright colors. Fountain solution is an indispensable chemical additive in the printing process of a color printing machine. It forms a uniform water film on the blank part of the printing plate to resist the infiltration of ink on the image into the blank part and prevent dirty plates. Vacuum degassing during storage of the fountain solution can achieve the advantages of removing bubbles, protecting ingredients and improving stability.

However, the cleaning tube and the liquid inlet pipe are connected together by threads, which may cause a certain distance between the first sealing rings and the connection is not appropriate, resulting in an unsatisfactory sealing effect in the degassing chamber. In view of this, we propose a liquid lubricating vacuum degassing device. Utility Model Content
