The scraper is a common mechanical device in paper machines, which can be divided into two types: one is the scraper for cleaning such as rolls (including the wire section/press section rolls, drying cylinders, calender rolls, take-up rolls); The other type is functional scrapers.

What is the pulping process in the papermaking process of the paper machine? How to formulate the pulp?Answer: In the process of papermaking, in order to improve the properties of paper or meet the needs of papermaking performance, and in some cases to save high-quality long fibers

Invention and development of the paper machine. After the invention of papermaking, in the long history, after thousands of years, it has spread from China to West Asia, Europe, America, and all over the world. It was not until more than 1,600 years after the invention of papermaking that the first paper machine appeared in the world

At present, the technologies for fault diagnosis and maintenance of paper machines mainly include oil analysis technology and vibration monitoring technology. Vibration monitoring technology mainly uses vibration signals to perform condition monitoring and fault diagnosis of paper machines.

The paper machine sizing system is responsible for the process of transporting the paper pulp to the headbox of the paper machine wire section through equipment such as slurry pumps, slurry pumps, and multi-stage screens. Among them, the slurry pump and the slurry pump are the most important equipment

Although paper machine pulping machinery and equipment involves several major fields such as special pulp and paper engineering machinery and equipment, general chemical machinery and equipment, hydraulic machinery and equipment, and environmental protection machinery and equipment
