RETAINING DEVICES & maintenance & assembly tools

The centerpiece of this gluing process is the DPP-8 doublepiston pump, which must provide a specific fluid pressure to apply the adhesive accurately. Each piston takes in compressed air on the upward stroke and displaces liquid from the glue cylinder on the downward stroke.

“You could call it a two-cylinder engine with the performance of an eight-cylinder,” said Ahler.

The DPP-8 piston pump regulates the air input pressure to set the required adhesive fluid pressure. The precise proportional pressure regulator VPPM from Festo controls the air volume on the input side. The VPPM has a linear pressure regulation range between 0.06 and 6 bar. For a delivery pump with a transmission ratio of 8:1, this means a reliable fluid pressure regulation range of 8 to 40 bar. The regulation starts with small increments to the control quality at 2 bar.
