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 development of paper machine and pulp equipment in recent yearsInternationally, modern papermaking machinery and papermaking pulp equipment are developing rapidly, and the degree of automation is getting higher and higher. At present, a single chemical pulp production line has a production scale of 600,000 t/year

Pulp equipment (or refining equipment) is to make the fibrous raw materials to be processed displace the primary and secondary walls of the fibers that are moving relative to each other, and then rupture, and then the fibers absorb water and swell and are cut, and finally fine fibers Change

According to the structural principle of pulp equipment, the main classifications are as follows:1. According to whether pulp equipment is continuous or not(1) Interval beater, such as Dutch beater, Volt beater.(2) Continuous beating machines, such as: column-back refiner, cone refiner, and disc refiner.

First, the slurry tankThe pulp tank of a paper machine pulp beater generally adopts a reinforced concrete structure. Simple grout tanks can also be constructed with bricks and cement. In order to make the pulp circulate well in the tank, reduce the friction of the pulp, and keep the pulp clean

Paper machines include two major categories: pulp machinery and paper machinery, as well as paper decoration and processing equipment. The specific lubrication methods are as follows:1. Lubrication of pulp machineryPulp machinery includes two types of equipment: material preparation and pulp making.
