The paper machinery industry is defined as machinery that includes raw material preparation, pulping, papermaking, up to roll or sheet finished products, and processing paper and board. For more details, the following is the definition and classification of the paper machinery industry compiled by Xiaobian.
Modern paper-making machinery can be said to be a behemoth with a high degree of integration. Its width can reach 10m, height can reach 20m, and length can even reach 150m. Each papermaking machine includes at least four main parts: forming part or wire part, press part, drying part, rewinding part
The composition of the wire section of the Fourdrinier paper machine:The wire part of the Fourdrinier paper machine is referred to as the Fourdrinier wire or the wire case for short. It is a typical fourdrinier network department. The main component of the net case is an endless fine woven net.
Dewatering process of vacuum suction box of Fourdrinier paper machineOn the vacuum water tank of the paper machine, the wet paper web has been basically shaped, and its main purpose is to dewater.For the vacuum suction box at low speed and low vacuum, the dehydration process of the wet paper web on a vacuum suction box can be roughly divided into three stages.
The top roll of the paper machine is the last dewatering device in the Fourdrinier section. After the wet paper web passes through the vacuum suction box, it is further dehydrated on the flat roll to reach a certain degree of dryness and has sufficient wet strength to be smoothly peeled from the surface of the forming wire and transferred to the press section.
Requirements for lubricating oil in various parts of paper machineThe modern paper machine is a behemoth with a high degree of integration, including four main parts: the forming part or the wire part, the pressing part, the drying part, and the rewinding part.
