The tension control of the rewinding and unwinding system of the paper machine, such as the rewinding machine and the off-machine coating machine. There are two forming methods for papermaking, namely flat paper and web paper. Due to the large number of high-speed printing presses

The paper machine sizing system is responsible for the process of transporting the paper pulp to the headbox of the paper machine wire section through equipment such as slurry pumps, slurry pumps, and multi-stage screens. Among them, the slurry pump and the slurry pump are the most important equipment

The paper machine is a combined machine composed of a series of ancillary equipment, divided into two parts, the wet part and the dry part. The wet part includes the sizing flow system, wire and pressing parts, and the dry part includes drying, calendering and coiling parts.

Although paper machine pulping machinery and equipment involves several major fields such as special pulp and paper engineering machinery and equipment, general chemical machinery and equipment, hydraulic machinery and equipment, and environmental protection machinery and equipment

Our country’s paper machine branch transmission equipment used SCR DC speed regulation in the past. Due to the existence of slip rings and carbon brushes, the reliability and accuracy of the paper machine are not high, which leads to the backwardness of the paper machine machinery.

At present, the technologies for fault diagnosis and maintenance of paper machines mainly include oil analysis technology and vibration monitoring technology. Vibration monitoring technology mainly uses vibration signals to perform condition monitoring and fault diagnosis of paper machines.
