Shell material: SS304/Cast Iron Roll Body: SS304/Carbon Steel Shaft Head: Cast Iron/ Ductile Iron Bearing: Cast Iron/Q235, Cast Steel Sealing System: Graphite, polymer polyethylene Hardness: HRC40-68 Degree Holes diameter: 0.4mm Loading capacity:3000KG Diameter: 500-1000mm Length: 1600-6200mm Center distance: 1650-7000mm Chemical resistance: High alkaline |
The vacuum couch roll is located at the end of the wire section of the paper machine. Its structure is basically the same as that of the suction roll. It is composed of a roll body, a vacuum box, a bearing seat on the operating side and the transmission side, a water spray tube, an air cushion tube, a rubber wheel, and a vacuum regulating valve. The vacuum couch roll is dehydrated through its internal vacuum chamber, and its dehydration strength mainly depends on the vacuum degree in the vacuum chamber. Dehydration time and the amount of air passing through wet paper are only secondary factors. The increase in vacuum degree has a significant impact on the dewatering ability of the couch roll.
