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.
