Vaccum suction roll :The vacuum suction roll is a key equipment in the press section, and its function is to transfer the paper sheet after the wire section is formed to the press section. Whether it is normal is very important to the stable operation of the paper machine.They are mainly composed of a rotating cylinder, a vacuum box inside the cylinder, a bearing support device, and a transmission device.Structure principleThe vacuum suction roll is an important component of paper leading from the flat roll of the wire section to the press section.

1.Working principle of suction couch rollerThe working principle of suction rollers is mainly based on the principles of vacuum adsorption and pressure difference. When the pulp passes through the vacuum roller, the vacuum chamber inside the roller forms negative pressure, attracting the moisture in the pulp. After being adsorbed onto the surface of the roller shaft, the moisture content of the paper significantly decreases through subsequent pressing and drying processes.

Vacuum couch roll is one of the main parts for fourdrinier dehydration and transmission of paper machine. The roller shell of vacuum couch roll designed by our company is made by precision machining with SUS304/316 stainless steel rolling. The roller surface openings are arranged into a double helix, the opening rate is more than 60%, effectively improving the strength and dewater evenness of the roller shell. Special seal has good self-lubrication and wear-resisting performance.

Dryer Vacuum Roll for High Speed Paper Machine Products information The Vac roll in Dryer section normally is a grooved and drilled and used in the individual felt dryer section of high-speed paper machines. Air is sucked in through the holes on the roller shell, creating negative pressure in the grooves. Negative pressure keeps the paper in contact with the fabric, preventing operational issues such as paper shaking. The generated support effect is optimized to be the highest on the curling edge, thereby improving paper edge support and achieving reliable tail threading.
