Do You Know The Component of Paper Machine Press Section

The composition of the paper machine press section:

The structural composition of the press section of different paper machines is different, but their basic composition is roughly similar. The diagram shows the structural composition of the press section of a low-speed culture paper machine.

The various devices and components included in the press section can be divided into the following parts:

1. Various types of presses formed by different matching combinations of press rolls;

2. Various accessories for pressing, such as pressure lever system, doctor blade, jet doctor blade, spray pipe, water tray, etc;

3. Various accessories for press felt, such as felt correctors, felt tensioners, spreader rolls, guide rolls and their doctor blades, washing and conditioning devices (felt suction box, felt press, water spray pipe), etc;

4. Various suction and transfer devices for paper webs, such as suction pick up rolls, vacuum suction box, paper carrier ropes, paper guide jets, etc;

5. Rolls on the paper path, such as paper guide rolls and paper loss conveyors;

6. Pneumatic pressurization system and hydraulic pressurization system;

7. Rack and walkway, etc.

Many of the components in the press section are standard or universal parts. This is because there are several presses in the pressing section, and many accessories can be interchangeable. Manufacturers often divide various types of press rolls into series based on parameters such as width and speed to create standard designs, which greatly accelerates the design and manufacturing cycle of the press section. By using these standard components, it is possible to design press sections suitable for different paper machines with minimal layout changes or the addition of specialized parts. In recent years, the composition of the pressing department has progressed towards standardization and modularization.

The form of the press machine frame varies depending on the different pressing forms. However, the frame is also developing towards building blocks, and even double rolls and compound presses have become standard components of building blocks, which can be assembled to form various different press parts.
