Liansheng Paper Industry
Project Overview
- Liansheng Paper (Longhai) Co., Ltd., located in Zhangzhou, Fujian, is a large domestic packaging paper manufacturer with a prominent position in the industry. This project involves the maintenance and retrofitting of the hood for the PM7 packaging paper machine, aiming to improve system operational stability and drying efficiency while reducing production energy consumption. The project requires the hood system to operate reliably with even ventilation, a short retrofitting cycle and no disruption to normal production. Zhengding Environment provided professional hood maintenance, retrofitting and commissioning services for this project, further strengthening its market reputation for hood system retrofits in the packaging paper sector.
- Delivered on schedule, the project passed commissioning successfully on the first attempt. The system runs stably, and the drying performance and energy-saving effect have both met the customer’s expectations.
Scope of Supply
- Zhengding Environment undertakes the hood maintenance and retrofitting project for the PM7 packaging paper machine, adapted to the medium-speed production conditions of packaging paper with a web width of 5800 mm and a machine speed of 350 m/min.
- It is responsible for comprehensive inspection, equipment maintenance, replacement of damaged components and sealing optimization of the PM7 paper machine hood system.
- The overall commissioning service of the hood system is completed to ensure on-time project delivery and stable startup and operation of the equipment.
Core technology
- Combined with the humid climate characteristics of Zhangzhou, Fujian, and in response to high standards for system tightness, stability and energy-efficient operation, the sealing and dehumidification design of the hood is reinforced to adapt to the local high-humidity production environment.
- The air volume ratio is optimized according to machine speed and evaporation load to precisely match the operating conditions of packaging paper production and optimize equipment operating parameters.
- Targeted sealing reinforcement and flow field adjustment are carried out in accordance with the paper machine production process to ensure stable, efficient and energy-saving operation of the system.
