What are the reasons for the leakage of the meshing position of the paper machine?

The reason for the leakage of the meshing position of the paper machine, the complete set of equipment that makes the pulp form the sub-linkage of the paper web is collectively called the paper machine, including the head box, the wire section, the press section, the drying section, the calender, the paper reel and the Transmission department and other main engines and auxiliary systems such as steam, water, vacuum, lubrication, and heat recovery.

Due to the uneven distribution of the mass center of gravity of the drying cylinder (the drying cylinder weighs about 5 tons per cylinder), and the drying cylinder is heated by steam, during the operation of the equipment, high-pressure steam will form condensate in the dryer, which will cause condensate during high-speed operation. Drainage is unfavorable, and a centrifugal force is formed in the dryer. The dryer can only move to both ends of the dryer to release this force, causing a certain frequency of vibration at the gear mesh. Usually modern multi-cylinder paper machines consist of 55-80 cylinders. The paper machine generates such vibrations during operation, which causes leakage at each meshing position.
