Product Description

Air Tube for Suction Roll

Rubber Air Tube for Suction Roll

The rubber air tube is mainly used on vacuum suction roll to increase pressure to achieve a good sealing effect. The air tube is usually used in conjunction with sealing strips.

Postion of air tube in the suction roll

Almost every paper machine has at least one suction roll, and some have as many as five, plus spares. They are a critical path element in the operation of the machine, and improper operation can significantly impact power consumption, and decrease the operating interval between changes.

A typical seal assembly is shown in left picture. In most modern designs, the side and siencer seals rest upon air tubes that lie under the seals in a U-shaped holder. The end deckles can be either fixedor resting on springs. The exact configuration depends on the manufacturer of the suction roll and the position.

Importance for sealing strip

The pressure of the sealing strip is determined by the supply pressure of the pneumatic tube set in the sealing groove. The normal operation of the equipment depends on the integrity of the vacuum roller sealing air tube.
