Many design parameters are used to design the paper machine, which are mainly determined by the basic data of the following aspects.

1.The basic data expressing the production capacity and adaptation range of paper machine

The main technical characteristics of the production capacity and adaptation range include the net paper width, the maximum working speed, the adjustment range, the forming department, the pressing department and the drying cadres.

2. The basic data expressing the performance structure of each part of the paper machine

In order to improve the standardization of paper machine design and manufacture, serialization, generalization, also to the paper machine each part of the main structure data in the paper machine design parameters, the structure data including the size of various roller and surface layer technical characteristics, the size and quantity of the panel, the size and number of drying cylinder, each part of the gauge, bearing distance, etc.

3. Represents the general data of the paper machine

Said the overview of the paper machine data, such as the length of the machine, total quality, since the rail surface of the maximum height, the total height, the transmission system, installed power, shows the paper machine area, space volume, unit production capacity, body quality and power consumption and other technical and economic indicators, so the data can not be ignored.

4. Basic data related to the process and technical indicators

 The technical indexes related to the design and calculation of paper machine include pulp beating degree, quantification of paper products produced, pulp concentration and dry degree of paper machine.

When determining the design parameters of the paper machine, it must also consider the designed paper machine to maintain a more advanced overall technical level, in order to meet the increasingly improved product quality requirements. At present, the most obvious technology development or technology to be developed of domestic paper machine is the integration of mechanical and electrical instruments. Therefore, the continuous addition of production parameters and quality parameters in the machine online detection instrument and control system is the primary consideration in the current domestic paper machine design.

In the design of the paper machine, reducing the production consumption, extending the service life of its parts and equipment, improving the operation efficiency and reducing the production cost are still the goals pursued by the designers.
