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.

The forming process of the paper web of the paper machine is the process in which the fiber suspension is dehydrated and deposited on the forming wire surface. It is mainly a hydrodynamic process; chemical forces and colloidal chemical forces also have a certain impact

The development of the dryer section of the paper machine:1. Single dry blanket drying device of paper machineThe drying section of a traditional multi-cylinder paper machine is equipped with two upper and lower drying cylinders with double blankets.

Whether a piece of equipment is operating normally, its key components play a very important role. The press roll is one of the more important parts in the paper machine. If there is a failure, it must be repaired and handled in time to avoid delays in production.

Paper dryer cylinder refers to a machine used in papermaking machinery to continuously dry the paper blank after the pulp is formed. Dozens of drying cylinders are placed crosswise in a paper machine.

Throughout the modern new high-speed headbox paper machine, it basically has the following main features:(1) Adopt high-efficiency hydraulic slurry rectifying components. Through the design of different structures and sizes of the hydraulic slurry rectifying elements
