The parts of the vacuum brazing furnace need cleaning steps

Vacuum brazing furnace need cleaning components in (1) first trough soaking in the preheating, again in ultrasonic cleaning tank (2) cleaning, use of ultrasonic cavitation effect to accelerate the pollutants dissolved and dissection, then rinse in cold rinse tank (3) by ultrasound, rinse off residual dirt, and make the workpiece cooling, the bigger the temperature difference between workpiece and solvent vapor is more conducive to the condensation, vapor phase cleaning effect is better. Finally in the solvent vapor layer (bath wash tank) RGL, rinse hot solvent vapors generated encounter cold condensation, solvent vapor into liquid, wetting, dissolve the contaminants on the surface of the workpiece, and like rain drops, and take away pollutants. When the workpiece temperature of solvent vapor temperature, condensation, no longer no longer drops on the surface of the parts, said end of vapor phase cleaning. Finally, the workpiece is put forward to leave vapor layer to the frozen area, artifacts slightly stay which is completely dry. Because the steam is clean, clean process without secondary pollution, so it is a completely clean cleaning process, can achieve very high cleanliness.
